ContentSniffer

class ContentSniffer(**properties: Any)

Superclasses: Object

Implemented Interfaces: SessionFeature

Sniffs the mime type of messages.

A ContentSniffer tries to detect the actual content type of the files that are being downloaded by looking at some of the data before the Message emits its got_headers signal. ContentSniffer implements SessionFeature, so you can add content sniffing to a session with add_feature or add_feature_by_type.

classmethod new() → ContentSniffer

The result may also be influenced by the Content-Type declared in msg’s response headers.
