Implemented Interfaces

SoupContentDecoder implements SoupSessionFeature and SoupContentProcessor.

Includes

#include <libsoup/soup.h>

Description

SoupContentDecoder handles adding the "Accept-Encoding" header on outgoing messages, and processing the "Content-Encoding" header on incoming ones. Currently it supports the "gzip", "deflate", and "br" content codings.

If you are using a plain SoupSession (ie, not SoupSessionAsync or SoupSessionSync), then a SoupContentDecoder will automatically be added to the session by default. (You can use SOUP_SESSION_REMOVE_FEATURE_BY_TYPE at construct time if you don't want this.) If you are using one of the deprecated SoupSession subclasses, you can add a SoupContentDecoder to your session with soup_session_add_feature() or soup_session_add_feature_by_type().

If SoupContentDecoder successfully decodes the Content-Encoding, it will set the SOUP_MESSAGE_CONTENT_DECODED flag on the message, and the message body and the chunks in the “got_chunk” signals will contain the decoded data; however, the message headers will be unchanged (and so "Content-Encoding" will still be present, "Content-Length" will describe the original encoded length, etc).

If "Content-Encoding" contains any encoding types that SoupContentDecoder doesn't recognize, then none of the encodings will be decoded (and the SOUP_MESSAGE_CONTENT_DECODED flag will not be set).

(Note that currently there is no way to (automatically) use Content-Encoding when sending a request body, or to pick specific encoding types to support.)
