# werkzeug.extract_path_info¶

werkzeug.extract_path_info(environ_or_baseurl, path_or_url, charset='utf-8', errors='replace', collapse_http_schemes=True)[source]

Extracts the path info from the given URL (or WSGI environment) and path. The path info returned is a unicode string, not a bytestring suitable for a WSGI environment. The URLs might also be IRIs.

If the path info could not be determined, None is returned.

Some examples:

>>> extract_path_info('http://example.com/app', '/app/hello')
u'/hello'
>>> extract_path_info('http://example.com/app',
...                   'https://example.com/app/hello')
u'/hello'
>>> extract_path_info('http://example.com/app',
...                   'https://example.com/app/hello',
...                   collapse_http_schemes=False) is None
True


Instead of providing a base URL you can also pass a WSGI environment.

New in version 0.6.

Parameters: environ_or_baseurl – a WSGI environment dict, a base URL or base IRI. This is the root of the application. path_or_url – an absolute path from the server root, a relative path (in which case it’s the path info) or a full URL. Also accepts IRIs and unicode parameters. charset – the charset for byte data in URLs errors – the error handling on decode collapse_http_schemes – if set to False the algorithm does not assume that http and https on the same server point to the same resource.
