Description

A SoupMessage represents an HTTP message that is being sent or received.

For client-side usage, if you are using the traditional SoupSession APIs (soup_session_queue_message() and soup_session_send_message()), you would create a SoupMessage with soup_message_new() or soup_message_new_from_uri(), set up its fields appropriately, and send it. If you are using the newer SoupRequest API, you would create a request with soup_session_request_http() or soup_session_request_http_uri(), and the returned SoupRequestHTTP will already have an associated SoupMessage that you can retrieve via soup_request_http_get_message().

For server-side usage, SoupServer will create SoupMessages automatically for incoming requests, which your application will receive via handlers.

Note that libsoup's terminology here does not quite match the HTTP specification: in RFC 2616, an "HTTP-message" is either a Request, or a Response. In libsoup, a SoupMessage combines both the request and the response.

void
soup_message_set_uri (SoupMessage *msg,
                      SoupURI *uri);

void
soup_message_set_status (SoupMessage *msg,
                         guint status_code);

Sets msg 's status code to status_code . If status_code is a known value, it will also set msg 's reason_phrase.

Parameters

msg

a SoupMessage

 

status_code

an HTTP status code

 

soup_message_set_status_full ()

void
soup_message_set_status_full (SoupMessage *msg,
                              guint status_code,
                              const char *reason_phrase);

                           const char *redirect_uri);

Sets msg 's status_code to status_code and adds a Location header pointing to redirect_uri . Use this from a SoupServer when you want to redirect the client to another URI.

redirect_uri can be a relative URI, in which case it is interpreted relative to msg 's current URI. In particular, if redirect_uri is just a path, it will replace the path and query of msg 's URI.

Parameters

msg

a SoupMessage

 

status_code

a 3xx status code

 

redirect_uri

the URI to redirect msg to

 

Since: 2.38


soup_message_is_keepalive ()

                                 GCallback callback,
                                 gpointer user_data);

Adds a signal handler to msg for signal , as with g_signal_connect(), but the callback will only be run if msg 's incoming messages headers (that is, the request_headers for a client SoupMessage, or the response_headers for a server SoupMessage) contain a header named header .

[skip]

Parameters

msg

a SoupMessage

 

signal

signal to connect the handler to.

 

header

HTTP response header to match against

 

callback

the header handler

                                      guint status_code,
                                      GCallback callback,
                                      gpointer user_data);

Adds a signal handler to msg for signal , as with g_signal_connect(), but the callback will only be run if msg has the status status_code .

signal must be a signal that will be emitted after msg 's status is set. For a client SoupMessage, this means it can't be a "wrote" signal. For a server SoupMessage, this means it can't be a "got" signal.

[skip]

Parameters

msg

a SoupMessage

 

signal

signal to connect the handler to.

 

status_code

status code to match against

                        SoupMessageFlags flags);

Sets the specified flags on msg .

Parameters

msg

a SoupMessage

 

flags

a set of SoupMessageFlags values

 

soup_message_get_flags ()

SoupMessageFlags
soup_message_get_flags (SoupMessage *msg);

SoupChunkAllocator ()

SoupBuffer *
(*SoupChunkAllocator) (SoupMessage *msg,
                       gsize max_len,
                       gpointer user_data);

SoupChunkAllocator is deprecated and should not be used in newly-written code.

Use SoupRequest if you want to read into your own buffers.

The prototype for a chunk allocation callback. This should allocate a new SoupBuffer and return it for the I/O layer to read message body data off the network into.

If max_len is non-0, it indicates the maximum number of bytes that could be read, based on what is known about the message size. Note that this might be a very large number, and you should not simply try to allocate that many bytes blindly. If max_len is 0, that means that libsoup does not know how many bytes remain to be read, and the allocator should return a buffer of a size that it finds convenient.

If the allocator returns NULL, the message will be paused. It is up to the application to make sure that it gets unpaused when it becomes possible to allocate a new buffer.

Parameters

msg

the SoupMessage the chunk is being allocated for

 

max_len

the maximum length that will be read, or 0.

 

user_data

the data passed to soup_message_set_chunk_allocator()

 

Returns

the new buffer (or NULL).

[nullable]


soup_message_disable_feature ()

void
soup_message_disable_feature (SoupMessage *msg,
                              GType feature_type);

This disables the actions of SoupSessionFeatures with the given feature_type (or a subclass of that type) on msg , so that msg is processed as though the feature(s) hadn't been added to the session. Eg, passing SOUP_TYPE_CONTENT_SNIFFER for feature_type will disable Content-Type sniffing on the message.

You must call this before queueing msg on a session; calling it on a message that has already been queued is undefined. In particular, you cannot call this on a message that is being requeued after a redirect or authentication.

Parameters

msg

a SoupMessage

 

feature_type

the GType of a SoupSessionFeature

 

Since: 2.28


soup_message_is_feature_disabled ()

gboolean
soup_message_is_feature_disabled (SoupMessage *msg,
                                  GType feature_type);

Get whether SoupSessionFeatures of the given feature_type (or a subclass of that type) are disabled on msg . See soup_message_disable_feature().

Parameters

msg

a SoupMessage

 

feature_type

the GType of a SoupSessionFeature

 

Returns

TRUE if feature is disabled, or FALSE otherwise.

Since: 2.72


soup_message_get_soup_request ()

SoupRequest *
soup_message_get_soup_request (SoupMessage *msg);

If msg is associated with a SoupRequest, this returns that request. Otherwise it returns NULL.

Parameters

msg

a SoupMessage

 

Returns

msg 's associated SoupRequest.

[transfer none]

Since: 2.42


soup_message_get_priority ()

SoupMessagePriority
soup_message_get_priority (SoupMessage *msg);

Retrieves the SoupMessagePriority. If not set this value defaults to SOUP_MESSAGE_PRIORITY_NORMAL.

Parameters

msg

a SoupMessage

 

Returns

the priority of the message.

Since: 2.44


soup_message_set_priority ()

void
soup_message_set_priority (SoupMessage *msg,
                           SoupMessagePriority priority);

Sets the priority of a message. Note that this won't have any effect unless used before the message is added to the session's message processing queue.

The message will be placed just before any other previously added message with lower priority (messages with the same priority are processed on a FIFO basis).

Setting priorities does not currently work with SoupSessionSync (or with synchronous messages on a plain SoupSession) because in the synchronous/blocking case, priority ends up being determined semi-randomly by thread scheduling.

Parameters

msg

a SoupMessage

 

priority

the SoupMessagePriority

 

Since: 2.44


soup_message_get_site_for_cookies ()

SoupURI *
soup_message_get_site_for_cookies (SoupMessage *msg);

Parameters

msg

a SoupMessage

 

Returns

the msg 's site for cookies SoupURI.

[transfer none]

Since: 2.70


soup_message_set_site_for_cookies ()

soup_message_set_site_for_cookies (SoupMessage *msg,
                                   SoupURI *site_for_cookies);

Sets site_for_cookies as the policy URL for same-site cookies for msg .

It is either the URL of the top-level document or NULL depending on whether the registrable domain of this document's URL matches the registrable domain of its parent's/opener's URL. For the top-level document it is set to the document's URL.

See the same-site spec for more information.

Parameters

msg

a SoupMessage

Types and Values

SoupMessage

typedef struct {
	const char         *method;

	guint               status_code;
	char               *reason_phrase;

	SoupMessageBody    *request_body;
	SoupMessageHeaders *request_headers;

	SoupMessageBody    *response_body;
	SoupMessageHeaders *response_headers;
} SoupMessage;

Represents an HTTP message being sent or received.

status_code will normally be a SoupStatus value, eg, SOUP_STATUS_OK, though of course it might actually be an unknown status code. reason_phrase is the actual text returned from the server, which may or may not correspond to the "standard" description of status_code . At any rate, it is almost certainly not localized, and not very descriptive even if it is in the user's language; you should not use reason_phrase in user-visible messages. Rather, you should look at status_code , and determine an end-user-appropriate message based on that and on what you were trying to do.

As described in the SoupMessageBody documentation, the request_body and response_body data fields will not necessarily be filled in at all times. When the body fields are filled in, they will be terminated with a '\0' byte (which is not included in the length), so you can use them as ordinary C strings (assuming that you know that the body doesn't have any other '\0' bytes).

For a client-side SoupMessage, request_body 's data is usually filled in right before libsoup writes the request to the network, but you should not count on this; use soup_message_body_flatten() if you want to ensure that data is filled in. If you are not using SoupRequest to read the response, then response_body 's data will be filled in before “finished” is emitted. (If you are using SoupRequest, then the message body is not accumulated by default, so response_body 's data will always be NULL.)

For a server-side SoupMessage, request_body 's data will be filled in before “got_body” is emitted.

To prevent the data field from being filled in at all (eg, if you are handling the data from a “got_chunk”, and so don't need to see it all at the end), call soup_message_body_set_accumulate() on response_body or request_body as appropriate, passing FALSE.

SOUP_HTTP_1_1

HTTP 1.1 (RFC 2616)

 

enum SoupMessageFlags

Various flags that can be set on a SoupMessage to alter its behavior.

Members

SOUP_MESSAGE_NO_REDIRECT

The session should not follow redirect (3xx) responses received by this message.

 

SOUP_MESSAGE_CAN_REBUILD

The caller will rebuild the request body if the message is restarted; see soup_message_body_set_accumulate() for more details.

 

SOUP_MESSAGE_OVERWRITE_CHUNKS

Deprecated: equivalent to calling soup_message_body_set_accumulate() on the incoming message body (ie, “response_body” for a client-side request), passing FALSE.

 

SOUP_MESSAGE_CONTENT_DECODED

Set by SoupContentDecoder to indicate that it has removed the Content-Encoding on a message (and so headers such as Content-Length may no longer accurately describe the body).

 

SOUP_MESSAGE_CERTIFICATE_TRUSTED

if set after an https response has been received, indicates that the server's SSL certificate is trusted according to the session's CA.

 

SOUP_MESSAGE_NEW_CONNECTION

Requests that the message should be sent on a newly-created connection, not reusing an existing persistent connection. Note that messages with non-idempotent “method”s behave this way by default, unless SOUP_MESSAGE_IDEMPOTENT is set.

 

SOUP_MESSAGE_IDEMPOTENT

The message is considered idempotent, regardless its “method”, and allows reuse of existing idle connections, instead of always requiring a new one, unless SOUP_MESSAGE_NEW_CONNECTION is set.

 

SOUP_MESSAGE_IGNORE_CONNECTION_LIMITS

Request that a new connection is created for the message if there aren't idle connections available and it's not possible to create new connections due to any of the connection limits has been reached. If a dedicated connection is eventually created for this message, it will be dropped when the message finishes. Since 2.50

 

SOUP_MESSAGE_DO_NOT_USE_AUTH_CACHE

The SoupAuthManager should not use the credentials cache for this message, neither to use cached credentials to automatically authenticate this message nor to cache the credentials after the message is successfully authenticated. This applies to both server and proxy authentication. Note that “authenticate” signal will be emitted, if you want to disable authentication for a message use soup_message_disable_feature() passing SOUP_TYPE_AUTH_MANAGER instead. Since 2.58

 

enum SoupMessagePriority

Priorities that can be set on a SoupMessage to instruct the message queue to process it before any other message with lower priority.

Members

SOUP_MESSAGE_PRIORITY_LOW

Use this for low priority messages, a SoupMessage with the default priority will be processed first.

 

SOUP_MESSAGE_PRIORITY_NORMAL

The default priotity, this is the priority assigned to the SoupMessage by default.

 

SOUP_MESSAGE_PRIORITY_HIGH

High priority, a SoupMessage with this priority will be processed before the ones with the default priority.

 

SOUP_MESSAGE_PRIORITY_VERY_HIGH

The highest priority, use this for very urgent SoupMessage as they will be the first ones to be attended.

Signal Details

The “content-sniffed” signal

void
user_function (SoupMessage *msg,
               gchar       *type,
               GHashTable  *params,
               gpointer     user_data)

This signal is emitted after “got-headers”, and before the first “got-chunk”. If content sniffing is disabled, or no content sniffing will be performed, due to the sniffer deciding to trust the Content-Type sent by the server, this signal is emitted immediately after “got-headers”, and type is NULL.

If the SoupContentSniffer feature is enabled, and the sniffer decided to perform sniffing, the first “got-chunk” emission may be delayed, so that the sniffer has enough data to correctly sniff the content. It notified the library user that the content has been sniffed, and allows it to change the header contents in the message, if desired.

After this signal is emitted, the data that was spooled so that sniffing could be done is delivered on the first emission of “got-chunk”.

Parameters

msg

the message

 

type

the content type that we got from sniffing

 

params

a GHashTable with the parameters.

[element-type utf8 utf8]

user_data

user data set when the signal handler was connected.

 

Flags: Run First

Since: 2.28


The “finished” signal

void
user_function (SoupMessage *msg,
               gpointer     user_data)

Emitted when all HTTP processing is finished for a message. (After “got_body” for client-side messages, or after “wrote_body” for server-side messages.)

Parameters

msg

the message

 

user_data

user data set when the signal handler was connected.

 

Flags: Run First


The “got-body” signal

void
user_function (SoupMessage *msg,
               gpointer     user_data)

Emitted after receiving the complete message body. (For a server-side message, this means it has received the request body. For a client-side message, this means it has received the response body and is nearly done with the message.)

See also soup_message_add_header_handler() and soup_message_add_status_code_handler(), which can be used to connect to a subset of emissions of this signal.

Parameters

msg

the message

 

user_data

user data set when the signal handler was connected.

 

Flags: Run First


The “got-chunk” signal

void
user_function (SoupMessage *msg,
               SoupBuffer  *chunk,
               gpointer     user_data)

Emitted after receiving a chunk of a message body. Note that "chunk" in this context means any subpiece of the body, not necessarily the specific HTTP 1.1 chunks sent by the other side.

If you cancel or requeue msg while processing this signal, then the current HTTP I/O will be stopped after this signal emission finished, and msg 's connection will be closed.

Parameters

msg

the message

 

chunk

the just-read chunk

 

user_data

user data set when the signal handler was connected.

 

Flags: Run First


The “got-headers” signal

void
user_function (SoupMessage *msg,
               gpointer     user_data)

Emitted after receiving all message headers for a message. (For a client-side message, this is after receiving the Status-Line and response headers; for a server-side message, it is after receiving the Request-Line and request headers.)

See also soup_message_add_header_handler() and soup_message_add_status_code_handler(), which can be used to connect to a subset of emissions of this signal.

If you cancel or requeue msg while processing this signal, then the current HTTP I/O will be stopped after this signal emission finished, and msg 's connection will be closed. (If you need to requeue a message--eg, after handling authentication or redirection--it is usually better to requeue it from a “got_body” handler rather than a “got_headers” handler, so that the existing HTTP connection can be reused.)

Parameters

msg

the message

 

user_data

user data set when the signal handler was connected.

 

Flags: Run First


The “got-informational” signal

void
user_function (SoupMessage *msg,
               gpointer     user_data)

Emitted after receiving a 1xx (Informational) response for a (client-side) message. The response_headers will be filled in with the headers associated with the informational response; however, those header values will be erased after this signal is done.

If you cancel or requeue msg while processing this signal, then the current HTTP I/O will be stopped after this signal emission finished, and msg 's connection will be closed.

Parameters

msg

the message

 

user_data

user data set when the signal handler was connected.

 

Flags: Run First


The “network-event” signal

void
user_function (SoupMessage       *msg,
               GSocketClientEvent event,
               GIOStream         *connection,
               gpointer           user_data)

Emitted to indicate that some network-related event related to msg has occurred. This essentially proxies the “event” signal, but only for events that occur while msg "owns" the connection; if msg is sent on an existing persistent connection, then this signal will not be emitted. (If you want to force the message to be sent on a new connection, set the SOUP_MESSAGE_NEW_CONNECTION flag on it.)

See “event” for more information on what the different values of event correspond to, and what connection will be in each case.

Parameters

msg

the message

 

event

the network event

 

connection

the current state of the network connection

 

user_data

user data set when the signal handler was connected.

 

Flags: Run First

Since: 2.38


The “restarted” signal

void
user_function (SoupMessage *msg,
               gpointer     user_data)

Emitted when a request that was already sent once is now being sent again (eg, because the first attempt received a redirection response, or because we needed to use authentication).

Parameters

msg

the message

 

user_data

user data set when the signal handler was connected.

 

Flags: Run First


The “starting” signal

void
user_function (SoupMessage *msg,
               gpointer     user_data)

Emitted just before a message is sent.

Parameters

msg

the message

 

user_data

user data set when the signal handler was connected.

 

Flags: Run First

Since: 2.50


The “wrote-body” signal

void
user_function (SoupMessage *msg,
               gpointer     user_data)

Emitted immediately after writing the complete body for a message. (For a client-side message, this means that libsoup is done writing and is now waiting for the response from the server. For a server-side message, this means that libsoup has finished writing the response and is nearly done with the message.)

Parameters

msg

the message

 

user_data

user data set when the signal handler was connected.

 

Flags: Run First


The “wrote-body-data” signal

void
user_function (SoupMessage *msg,
               SoupBuffer  *chunk,
               gpointer     user_data)

Emitted immediately after writing a portion of the message body to the network.

Unlike “wrote_chunk”, this is emitted after every successful write() call, not only after finishing a complete "chunk".

Parameters

msg

the message

 

chunk

the data written

 

user_data

user data set when the signal handler was connected.

 

Flags: Run First

Since: 2.24


The “wrote-chunk” signal

void
user_function (SoupMessage *msg,
               gpointer     user_data)

Emitted immediately after writing a body chunk for a message.

Note that this signal is not parallel to “got_chunk”; it is emitted only when a complete chunk (added with soup_message_body_append() or soup_message_body_append_buffer()) has been written. To get more useful continuous progress information, use “wrote_body_data”.

Parameters

msg

the message

 

user_data

user data set when the signal handler was connected.

 

Flags: Run First


The “wrote-headers” signal

void
user_function (SoupMessage *msg,
               gpointer     user_data)

Emitted immediately after writing the headers for a message. (For a client-side message, this is after writing the request headers; for a server-side message, it is after writing the response headers.)

Parameters

msg

the message

 

user_data

user data set when the signal handler was connected.

 

Flags: Run First


The “wrote-informational” signal

void
user_function (SoupMessage *msg,
               gpointer     user_data)

Emitted immediately after writing a 1xx (Informational) response for a (server-side) message.

Parameters

msg

the message

 

user_data

user data set when the signal handler was connected.
