Soup-3.0SoupSession

Soup session state object.

Session is the object that controls client-side HTTP. A Session encapsulates all of the state that libsoup is keeping on behalf of your program; cached HTTP connections, authentication information, etc. It also keeps track of various global options and features that you are using.

Most applications will only need a single Session; the primary reason you might need multiple sessions is if you need to have multiple independent authentication contexts. (Eg, you are connecting to a server and authenticating as two different users at different times; the easiest way to ensure that each Message is sent with the authentication information you intended is to use one session for the first user, and a second session for the other user.)

Additional Session functionality is provided by SessionFeature objects, which can be added to a session with Session.add_feature or Session.add_feature_by_type For example, Logger provides support for logging HTTP traffic, ContentDecoder provides support for compressed response handling, and ContentSniffer provides support for HTML5-style response body content sniffing. Additionally, subtypes of Auth can be added as features, to add support for additional authentication types.

All Soup.Sessions are created with a AuthManager, and support for SOUP_TYPE_AUTH_BASIC and SOUP_TYPE_AUTH_DIGEST. Additionally, sessions using the plain Session class (rather than one of its deprecated subtypes) have a ContentDecoder by default.

Note that all async methods will invoke their callbacks on the thread-default context at the time of the function call.

Properties

Compile-time signal type information.

This instance property is generated only for TypeScript type checking. It is not defined at runtime and should not be accessed in JS code.

$gtype: GType<Soup.Session>

Accessors

  • get idle_timeout(): number

    Connection lifetime (in seconds) when idle. Any connection left idle longer than this will be closed.

    Although you can change this property at any time, it will only affect newly-created connections, not currently-open ones. You can call Session.abort after setting this if you want to ensure that all future connections will have this timeout value.

    Returns number

  • set idle_timeout(val: number): void

    Parameters

    • val: number

    Returns void

  • get idleTimeout(): number

    Connection lifetime (in seconds) when idle. Any connection left idle longer than this will be closed.

    Although you can change this property at any time, it will only affect newly-created connections, not currently-open ones. You can call Session.abort after setting this if you want to ensure that all future connections will have this timeout value.

    Returns number

  • set idleTimeout(val: number): void

    Parameters

    • val: number

    Returns void

  • get max_conns(): number

    The maximum number of connections that the session can open at once.

    Returns number

  • get max_conns_per_host(): number

    The maximum number of connections that the session can open at once to a given host.

    Returns number

  • get maxConns(): number

    The maximum number of connections that the session can open at once.

    Returns number

  • get maxConnsPerHost(): number

    The maximum number of connections that the session can open at once to a given host.

    Returns number

  • get remote_connectable(): Gio.SocketConnectable

    Sets a socket to make outgoing connections on. This will override the default behaviour of opening TCP/IP sockets to the hosts specified in the URIs.

    This function is not required for common HTTP usage, but only when connecting to a HTTP service that is not using standard TCP/IP sockets. An example of this is a local service that uses HTTP over UNIX-domain sockets, in that case a Gio.UnixSocketAddress can be passed to this function.

    Returns Gio.SocketConnectable

  • get remoteConnectable(): Gio.SocketConnectable

    Sets a socket to make outgoing connections on. This will override the default behaviour of opening TCP/IP sockets to the hosts specified in the URIs.

    This function is not required for common HTTP usage, but only when connecting to a HTTP service that is not using standard TCP/IP sockets. An example of this is a local service that uses HTTP over UNIX-domain sockets, in that case a Gio.UnixSocketAddress can be passed to this function.

    Returns Gio.SocketConnectable

  • get timeout(): number

    The timeout (in seconds) for socket I/O operations (including connecting to a server, and waiting for a reply to an HTTP request).

    Although you can change this property at any time, it will only affect newly-created connections, not currently-open ones. You can call Session.abort after setting this if you want to ensure that all future connections will have this timeout value.

    Not to be confused with Session.idle_timeout (which is the length of time that idle persistent connections will be kept open).

    Returns number

  • set timeout(val: number): void

    Parameters

    • val: number

    Returns void

  • get user_agent(): string

    User-Agent string.

    If non-null, the value to use for the "User-Agent" header on Messages sent from this session.

    RFC 2616 says: "The User-Agent request-header field contains information about the user agent originating the request. This is for statistical purposes, the tracing of protocol violations, and automated recognition of user agents for the sake of tailoring responses to avoid particular user agent limitations. User agents SHOULD include this field with requests."

    The User-Agent header contains a list of one or more product tokens, separated by whitespace, with the most significant product token coming first. The tokens must be brief, ASCII, and mostly alphanumeric (although "-", "_", and "." are also allowed), and may optionally include a "/" followed by a version string. You may also put comments, enclosed in parentheses, between or after the tokens.

    If you set a Session.user_agent property that has trailing whitespace, Session will append its own product token (eg, libsoup/2.3.2) to the end of the header for you.

    Returns string

  • set user_agent(val: string): void

    Parameters

    • val: string

    Returns void

  • get userAgent(): string

    User-Agent string.

    If non-null, the value to use for the "User-Agent" header on Messages sent from this session.

    • val: string

    Returns void

Methods

  • Cancels all pending requests in session and closes all idle persistent connections.

    Returns void

  • If feature_type is the type of a class that implements SessionFeature, this creates a new feature of that type and adds it to session as with Session.add_feature. You can use this when you don't need to customize the new feature in any way. Adding multiple features of the same feature_type is not allowed.

    If feature_type is not a SessionFeature type, this gives each existing feature on session the chance to accept feature_type as a "subfeature". This can be used to add new Auth types, for instance.

    See the main Session documentation for information on what features are present in sessions by default.

    Parameters

    Returns void

  • Get the value used by session for the "Accept-Language" header on new requests.

    Returns string

    the accept language string

  • Gets whether session automatically sets the "Accept-Language" header on new requests.

    Returns boolean

    true if session sets "Accept-Language" header automatically, or false otherwise.

  • Get the timeout in seconds for idle connection lifetime currently used by session.

    Returns number

    the timeout in seconds

  • Get the maximum number of connections that session can open at once.

    Returns number

    the maximum number of connections

  • Get the maximum number of connections that session can open at once to a given host.

    Returns number

    the maximum number of connections per host

  • Get the timeout in seconds for socket I/O operations currently used by session.

    Returns number

    the timeout in seconds

  • Get the value used by session for the "User-Agent" header on new requests.

    Returns string

    the user agent string

  • Tests if session has at a feature of type feature_type (which can be the type of either a SessionFeature, or else a subtype of some class managed by another feature, such as Auth).

    Parameters

    Returns boolean

    true or false

  • Start a preconnection to msg.

    Once the connection is done, it will remain in idle state so that it can be reused by future requests. If there's already an idle connection for the given msg host, the operation finishes successfully without creating a new connection. If a new request for the given msg host is made while the preconnect is still ongoing, the request will take the ownership of the connection and the preconnect operation will finish successfully (if there's a connection error it will be handled by the request).

    The operation finishes when the connection is done or an error occurred.

    Parameters

    Returns Promise<boolean>

  • Start a preconnection to msg.

    Once the connection is done, it will remain in idle state so that it can be reused by future requests. If there's already an idle connection for the given msg host, the operation finishes successfully without creating a new connection. If a new request for the given msg host is made while the preconnect is still ongoing, the request will take the ownership of the connection and the preconnect operation will finish successfully (if there's a connection error it will be handled by the request).

    The operation finishes when the connection is done or an error occurred.

    Parameters

    Returns void

  • Start a preconnection to msg.

    Once the connection is done, it will remain in idle state so that it can be reused by future requests. If there's already an idle connection for the given msg host, the operation finishes successfully without creating a new connection. If a new request for the given msg host is made while the preconnect is still ongoing, the request will take the ownership of the connection and the preconnect operation will finish successfully (if there's a connection error it will be handled by the request).

    The operation finishes when the connection is done or an error occurred.

    Parameters

    Returns void | Promise<boolean>

  • Synchronously sends msg and waits for the beginning of a response.

    On success, a Gio.InputStream will be returned which you can use to read the response body. ("Success" here means only that an HTTP response was received and understood; it does not necessarily mean that a 2xx class status code was received.)

    If non-null, cancellable can be used to cancel the request; Session.send will return a Gio.IOErrorEnum.CANCELLED error. Note that with requests that have side effects (eg, POST, PUT, DELETE) it is possible that you might cancel the request after the server acts on it, but before it returns a response, leaving the remote resource in an unknown state.

    If msg is requeued due to a redirect or authentication, the initial (3xx/401/407) response body will be suppressed, and Session.send will only return once a final response has been received.

    Possible error domains include SessionError, Gio.IOErrorEnum, and Gio.TlsError which you may want to specifically handle.

    Parameters

    Returns Gio.InputStream

    a Gio.InputStream for reading the response body, or null on error.

  • Set the value to use for the "Accept-Language" header on Messages sent from session.

    If accept_language is null then no "Accept-Language" will be included in requests. See Session.accept_language for more information.

    Parameters

    • accept_language: string

      the languages string

    Returns void

  • Set a timeout in seconds for idle connection lifetime to be used by session on new connections.

    See Session.idle_timeout for more information.

    Parameters

    • timeout: number

      a timeout in seconds

    Returns void

  • Set a timeout in seconds for socket I/O operations to be used by session on new connections.

    See Session.timeout for more information.

    Parameters

    • timeout: number

      a timeout in seconds

    Returns void

  • Set the value to use for the "User-Agent" header on Messages sent from session.

    If user_agent has trailing whitespace, session will append its own product token (eg, libsoup/3.0.0) to the end of the header for you. If user_agent is null then no "User-Agent" will be included in requests. See Session.user_agent for more information.

    Parameters

    • user_agent: string

      the user agent string

    Returns void

Methods - Inherited from GObject

  • Creates a binding between source_property on source and target_property on target.

    Whenever the source_property is changed the target_property is updated using the same value. For instance:

      g_object_bind_property (action, "active", widget, "sensitive", 0);
    

    Will result in the "sensitive" property of the widget GObject.Object instance to be updated with the same value of the "active" property of the action GObject.Object instance.

    If flags contains GObject.BindingFlags.BIDIRECTIONAL then the binding will be mutual: if target_property on target changes then the source_property on source will be updated as well.

    The binding will automatically be removed when either the source or the target instances are finalized. To remove the binding without affecting the source and the target you can just call g_object_unref() on the returned GObject.Binding instance.

    Removing the binding by calling g_object_unref() on it must only be done if the binding, source and target are only used from a single thread and it is clear that both source and target outlive the binding. Especially it is not safe to rely on this if the binding, source or target can be finalized from different threads. Keep another reference to the binding and use g_binding_unbind() instead to be on the safe side.

    A GObject.Object can have multiple bindings.

    Parameters

    Returns GObject.Binding

    the GObject.Binding instance representing the binding between the two GObject.Object instances. The binding is released whenever the GObject.Binding reference count reaches zero.

  • Complete version of g_object_bind_property().

    Creates a binding between source_property on source and target_property on target, allowing you to set the transformation functions to be used by the binding.

    If flags contains GObject.BindingFlags.BIDIRECTIONAL then the binding will be mutual: if target_property on target changes then the source_property on source will be updated as well. The transform_from function is only used in case of bidirectional bindings, otherwise it will be ignored

    The binding will automatically be removed when either the source or the target instances are finalized. This will release the reference that is being held on the GObject.Binding instance; if you want to hold on to the GObject.Binding instance, you will need to hold a reference to it.

    To remove the binding, call g_binding_unbind().

    A GObject.Object can have multiple bindings.

    The same user_data parameter will be used for both transform_to and transform_from transformation functions; the notify function will be called once, when the binding is removed. If you need different data for each transformation function, please use g_object_bind_property_with_closures() instead.

    Parameters

    • source_property: string

      the property on source to bind

    • target: GObject.Object

      the target GObject.Object

    • target_property: string

      the property on target to bind

    • flags: GObject.BindingFlags

      flags to pass to GObject.Binding

    • Optionaltransform_to: BindingTransformFunc

      the transformation function from the source to the target, or null to use the default

    • Optionaltransform_from: BindingTransformFunc

      the transformation function from the target to the source, or null to use the default

    • Optionalnotify: DestroyNotify

      a function to call when disposing the binding, to free resources used by the transformation functions, or null if not required

    Returns GObject.Binding

    the GObject.Binding instance representing the binding between the two GObject.Object instances. The binding is released whenever the GObject.Binding reference count reaches zero.

  • Creates a binding between source_property on source and target_property on target, allowing you to set the transformation functions to be used by the binding.

    This function is the language bindings friendly version of g_object_bind_property_full(), using GClosures instead of function pointers.

    Parameters

    Returns GObject.Binding

    the GObject.Binding instance representing the binding between the two GObject.Object instances. The binding is released whenever the GObject.Binding reference count reaches zero.

  • Disconnects a handler from an instance so it will not be called during any future or currently ongoing emissions of the signal it has been connected to.

    Parameters

    • id: number

      Handler ID of the handler to be disconnected

    Returns void

  • This function is intended for GObject.Object implementations to re-enforce a [floating][floating-ref] object reference. Doing this is seldom required: all GInitiallyUnowneds are created with a floating reference which usually just needs to be sunken by calling g_object_ref_sink().

    Returns void

  • Increases the freeze count on object. If the freeze count is non-zero, the emission of "notify" signals on object is stopped. The signals are queued until the freeze count is decreased to zero. Duplicate notifications are squashed so that at most one GObject.Object::notify signal is emitted for each property modified while the object is frozen.

    This is necessary for accessors that modify multiple properties to prevent premature notification while the object is still being modified.

    Returns void

  • Gets a named field from the objects table of associations (see g_object_set_data()).

    Parameters

    • key: string

      name of the key for that association

    Returns any

    the data if found, or null if no such data exists.

  • Gets a property of an object.

    The value can be:

    • an empty GObject.Value initialized by G_VALUE_INIT, which will be automatically initialized with the expected type of the property (since GLib 2.60)
    • a GObject.Value initialized with the expected type of the property
    • a GObject.Value initialized with a type to which the expected type of the property can be transformed

    In general, a copy is made of the property contents and the caller is responsible for freeing the memory by calling GObject.Value.unset.

    Note that GObject.Object.get_property is really intended for language bindings, GObject.Object.get is much more convenient for C programming.

    Parameters

    • property_name: string

      The name of the property to get

    • value: any

      Return location for the property value. Can be an empty GObject.Value initialized by G_VALUE_INIT (auto-initialized with expected type since GLib 2.60), a GObject.Value initialized with the expected property type, or a GObject.Value initialized with a transformable type

    Returns any

  • This function gets back user data pointers stored via g_object_set_qdata().

    Parameters

    • quark: number

      A GLib.Quark, naming the user data pointer

    Returns any

    The user data pointer set, or null

  • Gets n_properties properties for an object. Obtained properties will be set to values. All properties must be valid. Warnings will be emitted and undefined behaviour may result if invalid properties are passed in.

    Parameters

    • names: string[]

      the names of each property to get

    • values: any[]

      the values of each property to get

    Returns void

  • Emits a "notify" signal for the property property_name on object.

    When possible, eg. when signaling a property change from within the class that registered the property, you should use g_object_notify_by_pspec() instead.

    Note that emission of the notify signal may be blocked with g_object_freeze_notify(). In this case, the signal emissions are queued and will be emitted (in reverse order) when g_object_thaw_notify() is called.

    Parameters

    • property_name: string

      the name of a property installed on the class of object.

    Returns void

  • Emits a "notify" signal for the property specified by pspec on object.

    This function omits the property name lookup, hence it is faster than g_object_notify().

    One way to avoid using g_object_notify() from within the class that registered the properties, and using g_object_notify_by_pspec() instead, is to store the GParamSpec used with g_object_class_install_property() inside a static array, e.g.:

      typedef enum
    {
    PROP_FOO = 1,
    PROP_LAST
    } MyObjectProperty;

    static GParamSpec *properties[PROP_LAST];

    static void
    my_object_class_init (MyObjectClass *klass)
    {
    properties[PROP_FOO] = g_param_spec_int ("foo", NULL, NULL,
    0, 100,
    50,
    G_PARAM_READWRITE | G_PARAM_STATIC_STRINGS);
    g_object_class_install_property (gobject_class,
    PROP_FOO,
    properties[PROP_FOO]);
    }

    and then notify a change on the "foo" property with:

      g_object_notify_by_pspec (self, properties[PROP_FOO]);
    

    Parameters

    Returns void

  • Increases the reference count of object.

    Since GLib 2.56, if GLIB_VERSION_MAX_ALLOWED is 2.56 or greater, the type of object will be propagated to the return type (using the GCC typeof() extension), so any casting the caller needs to do on the return type must be explicit.

    Returns GObject.Object

    the same object

  • Increase the reference count of object, and possibly remove the [floating][floating-ref] reference, if object has a floating reference.

    In other words, if the object is floating, then this call "assumes ownership" of the floating reference, converting it to a normal reference by clearing the floating flag while leaving the reference count unchanged. If the object is not floating, then this call adds a new normal reference increasing the reference count by one.

    Since GLib 2.56, the type of object will be propagated to the return type under the same conditions as for g_object_ref().

    Returns GObject.Object

    object

  • Releases all references to other objects. This can be used to break reference cycles.

    This function should only be called from object system implementations.

    Returns void

  • Sets multiple properties of an object at once. The properties argument should be a dictionary mapping property names to values.

    Parameters

    • properties: { [key: string]: any }

      Object containing the properties to set

    Returns void

  • Each object carries around a table of associations from strings to pointers. This function lets you set an association.

    If the object already had an association with that name, the old association will be destroyed.

    Internally, the key is converted to a GLib.Quark using g_quark_from_string(). This means a copy of key is kept permanently (even after object has been finalized) — so it is recommended to only use a small, bounded set of values for key in your program, to avoid the GLib.Quark storage growing unbounded.

    Parameters

    • key: string

      name of the key

    • Optionaldata: any

      data to associate with that key

    Returns void

  • Sets a property on an object.

    Parameters

    • property_name: string

      The name of the property to set

    • value: any

      The value to set the property to

    Returns void

  • Remove a specified datum from the object's data associations, without invoking the association's destroy handler.

    Parameters

    • key: string

      name of the key

    Returns any

    the data if found, or null if no such data exists.

  • This function gets back user data pointers stored via g_object_set_qdata() and removes the data from object without invoking its destroy() function (if any was set). Usually, calling this function is only required to update user data pointers with a destroy notifier, for example:

    void
    object_add_to_user_list (GObject *object,
    const gchar *new_string)
    {
    // the quark, naming the object data
    GQuark quark_string_list = g_quark_from_static_string ("my-string-list");
    // retrieve the old string list
    GList *list = g_object_steal_qdata (object, quark_string_list);

    // prepend new string
    list = g_list_prepend (list, g_strdup (new_string));
    // this changed 'list', so we need to set it again
    g_object_set_qdata_full (object, quark_string_list, list, free_string_list);
    }
    static void
    free_string_list (gpointer data)
    {
    GList *node, *list = data;

    for (node = list; node; node = node->next)
    g_free (node->data);
    g_list_free (list);
    }

    Using g_object_get_qdata() in the above example, instead of g_object_steal_qdata() would have left the destroy function set, and thus the partial string list would have been freed upon g_object_set_qdata_full().

    Parameters

    • quark: number

      A GLib.Quark, naming the user data pointer

    Returns any

    The user data pointer set, or null

  • Stops a signal's emission by the given signal name. This will prevent the default handler and any subsequent signal handlers from being invoked.

    Parameters

    • detailedName: string

      Name of the signal to stop emission of

    Returns void

  • Reverts the effect of a previous call to g_object_freeze_notify(). The freeze count is decreased on object and when it reaches zero, queued "notify" signals are emitted.

    Duplicate notifications for each property are squashed so that at most one GObject.Object::notify signal is emitted for each property, in the reverse order in which they have been queued.

    It is an error to call this function when the freeze count is zero.

    Returns void

  • Decreases the reference count of object. When its reference count drops to 0, the object is finalized (i.e. its memory is freed).

    If the pointer to the GObject.Object may be reused in future (for example, if it is an instance variable of another object), it is recommended to clear the pointer to null rather than retain a dangling pointer to a potentially invalid GObject.Object instance. Use g_clear_object() for this.

    Returns void

  • the constructed function is called by g_object_new() as the final step of the object creation process. At the point of the call, all construction properties have been set on the object. The purpose of this call is to allow for object initialisation steps that can only be performed after construction properties have been set. constructed implementors should chain up to the constructed call of their parent class to allow it to complete its initialisation.

    Returns void

  • the dispose function is supposed to drop all references to other objects, but keep the instance otherwise intact, so that client method invocations still work. It may be run multiple times (due to reference loops). Before returning, dispose should chain up to the dispose method of the parent class.

    Returns void

  • instance finalization function, should finish the finalization of the instance begun in dispose and chain up to the finalize method of the parent class.

    Returns void

  • Emits a "notify" signal for the property property_name on object.

    When possible, eg. when signaling a property change from within the class that registered the property, you should use g_object_notify_by_pspec() instead.

    Note that emission of the notify signal may be blocked with g_object_freeze_notify(). In this case, the signal emissions are queued and will be emitted (in reverse order) when g_object_thaw_notify() is called.

    Parameters

    Returns void

  • the generic setter for all properties of this type. Should be overridden for every type with properties. If implementations of set_property don't emit property change notification explicitly, this will be done implicitly by the type system. However, if the notify signal is emitted explicitly, the type system will not emit it a second time.

    Parameters

    Returns void

  • This function essentially limits the life time of the closure to the life time of the object. That is, when the object is finalized, the closure is invalidated by calling g_closure_invalidate() on it, in order to prevent invocations of the closure with a finalized (nonexisting) object. Also, g_object_ref() and g_object_unref() are added as marshal guards to the closure, to ensure that an extra reference count is held on object during invocation of the closure. Usually, this function will be called on closures that use this object as closure data.

    Parameters

    Returns void

  • Add a property to an interface; this is only useful for interfaces that are added to GObject-derived types. Adding a property to an interface forces all objects classes with that interface to have a compatible property. The compatible property could be a newly created GObject.ParamSpec, but normally g_object_class_override_property() will be used so that the object class only needs to provide an implementation and inherits the property description, default value, bounds, and so forth from the interface property.

    This function is meant to be called from the interface's default vtable initialization function (the class_init member of GObject.TypeInfo.) It must not be called after after class_init has been called for any object types implementing this interface.

    If pspec is a floating reference, it will be consumed.

    Parameters

    Returns void

  • Parameters

    • property_id: number

      the new property ID

    • name: string

      the name of a property registered in a parent class or in an interface of this class.

    Returns void
