Here an example: >>> from werkzeug import create_environ >>> env = create_environ("/?param=foo", "http://localhost/script") >>> get_current_url(env) 'http://localhost/script/?param=foo' >>> get_current_url(env, root_only=True) 'http://localhost/script/' >>> get_current_url(env, host_only=True) 'http://localhost/' >>> get_current_url(env, strip_querystring=True) 'http://localhost/script/' :param environ: the WSGI environment to get the current URL from. :param root_only: set `True` if you only want the root URL. :param strip_querystring: set to `True` if you don't want the querystring. :param host_only: set to `True` if the host URL should be returned. zwsgi.url_schemez://��/ZSCRIPT_NAMEZ PATH_INFOZQUERY_STRING�?)r�append�joinrr�rstrip�lstrip)rZ root_onlyZstrip_querystringZ host_only�tmp�cat�qsrrr�get_current_url<s r*c Cs:y|d�d�d��Sttfk r4|�d�SXdS)z� Naively yank the first IP address in an X-Forwarded-For header and assume this is correct.
