Description

A WebKitWebResource encapsulates content for each resource at the end of a particular URI. For example, one WebKitWebResource will be created for each separate image and stylesheet when a page is loaded.

You can access the response and the URI for a given WebKitWebResource, using webkit_web_resource_get_uri() and webkit_web_resource_get_response(), as well as the raw data, using webkit_web_resource_get_data().

Functions

webkit_web_resource_get_uri ()

const gchar *
webkit_web_resource_get_uri (WebKitWebResource *resource);

Returns the current active URI of resource . The active URI might change during a load operation:

When the resource load starts, the active URI is the requested URI
When the initial request is sent to the server, “sent-request” signal is emitted without a redirected response, the active URI is the URI of the request sent to the server.
In case of a server redirection, “sent-request” signal is emitted again with a redirected response, the active URI is the URI the request was redirected to.
When the response is received from the server, the active URI is the final one and it will not change again.

You can monitor the active URI by connecting to the notify::uri signal of resource .

Parameters

resource

a WebKitWebResource

Returns

the current active URI of resource

webkit_web_resource_get_response ()

WebKitURIResponse *
webkit_web_resource_get_response (WebKitWebResource *resource);

Retrieves the WebKitURIResponse of the resource load operation. This method returns NULL if called before the response is received from the server. You can connect to notify::response signal to be notified when the response is received.

Parameters

resource

a WebKitWebResource

Returns

the WebKitURIResponse, or NULL if the response hasn't been received yet.

webkit_web_resource_get_data ()

void
webkit_web_resource_get_data (WebKitWebResource *resource,
                              GCancellable *cancellable,
                              GAsyncReadyCallback callback,
                              gpointer user_data);

Asynchronously get the raw data for resource .

When the operation is finished, callback will be called. You can then call webkit_web_resource_get_data_finish() to get the result of the operation.

Parameters

resource	a WebKitWebResource
cancellable	a GCancellable or `NULL` to ignore.	[allow-none]
callback	a GAsyncReadyCallback to call when the request is satisfied.	[scope async]
user_data	the data to pass to callback function.	[closure]

webkit_web_resource_get_data_finish ()

guchar *
webkit_web_resource_get_data_finish (WebKitWebResource *resource,
                                     GAsyncResult *result,
                                     gsize *length,
                                     GError **error);

Finish an asynchronous operation started with webkit_web_resource_get_data().

Parameters

resource	a WebKitWebResource
result	a GAsyncResult
length	return location for the length of the resource data.	[out][allow-none]
error	return location for error or `NULL` to ignore

Returns

a string with the data of resource , or NULL in case of error. if length is not NULL, the size of the data will be assigned to it.

Property Details

The `“response”` property

  “response”                 WebKitURIResponse *

The WebKitURIResponse associated with this resource.

Flags: Read

The `“uri”` property

  “uri”                      gchar *

The current active URI of the WebKitWebResource. See webkit_web_resource_get_uri() for more details.

Flags: Read

Default value: NULL

Signal Details

The `“failed”` signal

void
user_function (WebKitWebResource *resource,
               gpointer           error,
               gpointer           user_data)

This signal is emitted when an error occurs during the resource load operation.

Parameters

resource	the WebKitWebResource
error	the GError that was triggered
user_data	user data set when the signal handler was connected.

Flags: Run Last

The `“failed-with-tls-errors”` signal

void
user_function (WebKitWebResource   *resource,
               GTlsCertificate     *certificate,
               GTlsCertificateFlags errors,
               gpointer             user_data)

This signal is emitted when a TLS error occurs during the resource load operation.

Parameters

resource	the WebKitWebResource
certificate	a GTlsCertificate
errors	a GTlsCertificateFlags with the verification status of `certificate`
user_data	user data set when the signal handler was connected.

Flags: Run Last

Since: 2.8

The `“finished”` signal

void
user_function (WebKitWebResource *resource,
               gpointer           user_data)

This signal is emitted when the resource load finishes successfully or due to an error. In case of errors “failed” signal is emitted before this one.

Parameters

resource	the WebKitWebResource
user_data	user data set when the signal handler was connected.

Flags: Run Last

The `“received-data”` signal

void
user_function (WebKitWebResource *resource,
               guint64            data_length,
               gpointer           user_data)

This signal is emitted after response is received, every time new data has been received. It's useful to know the progress of the resource load operation.

Parameters

resource	the WebKitWebResource
data_length	the length of data received in bytes
user_data	user data set when the signal handler was connected.

Flags: Run Last

The `“sent-request”` signal

void
user_function (WebKitWebResource *resource,
               WebKitURIRequest  *request,
               WebKitURIResponse *redirected_response,
               gpointer           user_data)

This signal is emitted when request has been sent to the server. In case of a server redirection this signal is emitted again with the request argument containing the new request sent to the server due to the redirection and the redirected_response parameter containing the response received by the server for the initial request.

Parameters

resource	the WebKitWebResource
request	a WebKitURIRequest
redirected_response	a WebKitURIResponse, or `NULL`
user_data	user data set when the signal handler was connected.

Flags: Run Last
