SoupMultipartInputStream

SoupMultipartInputStream — Multipart input handling stream

Implemented Interfaces

SoupMultipartInputStream implements GPollableInputStream.

Includes

#include <libsoup/soup.h>

Description

This adds support for the multipart responses. For handling the multiple parts the user needs to wrap the GInputStream obtained by sending the request with a SoupMultipartInputStream and use soup_multipart_input_stream_next_part() before reading. Responses which are not wrapped will be treated like non-multipart responses.

Note that although SoupMultipartInputStream is a GInputStream, you should not read directly from it, and the results are undefined if you do.

Functions

soup_multipart_input_stream_new ()

SoupMultipartInputStream *
soup_multipart_input_stream_new (SoupMessage *msg,
                                 GInputStream *base_stream);

Creates a new SoupMultipartInputStream that wraps the GInputStream obtained by sending the SoupRequest. Reads should not be done directly through this object, use the input streams returned by soup_multipart_input_stream_next_part() or its async counterpart instead.

Parameters

msg

the SoupMessage the response is related to.

 

base_stream

the GInputStream returned by sending the request.

 

Returns

a new SoupMultipartInputStream

Since 2.40


soup_multipart_input_stream_get_headers ()

SoupMessageHeaders *
soup_multipart_input_stream_get_headers
                               (SoupMultipartInputStream *multipart);

Obtains the headers for the part currently being processed. Note that the SoupMessageHeaders that are returned are owned by the SoupMultipartInputStream and will be replaced when a call is made to soup_multipart_input_stream_next_part() or its async counterpart, so if keeping the headers is required, a copy must be made.

Note that if a part had no headers at all an empty SoupMessageHeaders will be returned.

Parameters

multipart

a SoupMultipartInputStream.

 

Returns

a SoupMessageHeaders containing the headers for the part currently being processed or NULL if the headers failed to parse.

Since 2.40


soup_multipart_input_stream_next_part ()

GInputStream *
soup_multipart_input_stream_next_part (SoupMultipartInputStream *multipart,
                                       GCancellable *cancellable,
                                       GError **error);

Obtains an input stream for the next part. When dealing with a multipart response the input stream needs to be wrapped in a SoupMultipartInputStream and this function or its async counterpart need to be called to obtain the first part for reading.

After calling this function, soup_multipart_input_stream_get_headers() can be used to obtain the headers for the first part. A read of 0 bytes indicates the end of the part; a new call to this function should be done at that point, to obtain the next part.

Parameters

multipart

the SoupMultipartInputStream

 

cancellable

a GCancellable

 

error

a GError

 

Returns

a new GInputStream, or NULL if there are no more parts.

soup_multipart_input_stream_next_part_async ()

void
soup_multipart_input_stream_next_part_async
                               (SoupMultipartInputStream *multipart,
                                int io_priority,
                                GCancellable *cancellable,
                                GAsyncReadyCallback callback,
                                gpointer data);

Obtains a GInputStream for the next request. See soup_multipart_input_stream_next_part() for details on the workflow.

Parameters

multipart

the SoupMultipartInputStream.

 

io_priority

the I/O priority for the request.

 

cancellable

a GCancellable.

 

callback

callback to call when request is satisfied.

 

data

data for callback

soup_multipart_input_stream_next_part_finish ()

GInputStream *
soup_multipart_input_stream_next_part_finish
                               (SoupMultipartInputStream *multipart,
                                GAsyncResult *result,
                                GError **error);

Finishes an asynchronous request for the next part.

Parameters

multipart

a SoupMultipartInputStream.

 

result

a GAsyncResult.

 

error

a GError location to store any error, or NULL to ignore.

 

Returns

a newly created GInputStream for reading the next part or NULL if there are no more parts.

Since 2.40

Types and Values

struct SoupMultipartInputStream

struct SoupMultipartInputStream;
