Implemented Interfaces

SoupContentSniffer implements SoupSessionFeature and SoupContentProcessor.

Includes

#include <libsoup/soup.h>

Description

A SoupContentSniffer tries to detect the actual content type of the files that are being downloaded by looking at some of the data before the SoupMessage emits its “got-headers” signal. SoupContentSniffer implements SoupSessionFeature, so you can add content sniffing to a session with soup_session_add_feature() or soup_session_add_feature_by_type().

Functions

soup_content_sniffer_new ()

SoupContentSniffer *
soup_content_sniffer_new (void);

Creates a new SoupContentSniffer.

Returns

a new SoupContentSniffer

soup_content_sniffer_sniff ()

char *
soup_content_sniffer_sniff (SoupContentSniffer *sniffer,
                            SoupMessage *msg,
                            GBytes *buffer,
                            GHashTable **params);

Sniffs buffer to determine its Content-Type. The result may also be influenced by the Content-Type declared in msg 's response headers.

Parameters

sniffer	a SoupContentSniffer
msg	the message to sniff
buffer	a buffer containing the start of `msg` 's response body
params	return location for Content-Type parameters (eg, "charset"), or `NULL`.	[element-type utf8 utf8][out][transfer full][nullable]

Returns

the sniffed Content-Type of buffer ; this will never be NULL, but may be "application/octet-stream".
