Werkzeug always uses utf-8 URLs internally because this is what browsers and HTTP do as well. In some places where it accepts an URL it also accepts a unicode IRI and converts it into a URI. Examples for IRI versus URI: >>> iri_to_uri(u'http://☃.net/') 'http://xn--n3h.net/' >>> iri_to_uri(u'http://üser:pässword@☃.net/påth') 'http://%C3%BCser:p%C3%A4ssword@xn--n3h.net/p%C3%A5th' There is a general problem with IRI and URI conversion with some protocols that appear in the wild that are in violation of the URI specification. In places where Werkzeug goes through a forced IRI to URI conversion it will set the `safe_conversion` flag which will not perform a conversion if the end result is already ASCII. This can mean that the return value is not an entirely correct URI but it will not destroy such invalid URLs in the process. As an example consider the following two IRIs:: magnet:?xt=uri:whatever itms-services://?action=download-manifest The internal representation after parsing of those URLs is the same and there is no way to reconstruct the original one. If safe conversion is enabled however this function becomes a noop for both of those strings as they both can be considered URIs. .. versionadded:: 0.6 .. versionchanged:: 0.9.6 The `safe_conversion` parameter was added. :param iri: The IRI to convert. :param charset: The charset for the URI. :param safe_conversion: indicates if a safe conversion should take place.

There is a difference in key decoding on different Python versions. On Python 3 keys will always be fully decoded whereas on Python 2, keys will remain bytestrings if they fit into ASCII. On 2.x keys can be forced to be unicode by setting `decode_keys` to `True`. If the charset is set to `None` no unicode decoding will happen and raw bytes will be returned. Per default a missing value for a key will default to an empty key. If you don't want that behavior you can set `include_empty` to `False`. Per default encoding errors are ignored. If you want a different behavior you can set `errors` to ``'replace'`` or ``'strict'``. In strict mode a `HTTPUnicodeError` is raised. .. versionchanged:: 0.5 In previous versions ";" and "&" could be used for url decoding. This changed in 0.5 where only "&" is supported.

The function can be called with any number of positional and keyword arguments which than are used to assemble the URL. Works with URLs and posix paths. Positional arguments are appended as individual segments to the path of the URL: >>> href = Href('/foo') >>> href('bar', 23) '/foo/bar/23' >>> href('foo', bar=23) '/foo/foo?bar=23' If any of the arguments (positional or keyword) evaluates to `None` it will be skipped. If no keyword arguments are given the last argument can be a :class:`dict` or :class:`MultiDict` (or any other dict subclass), otherwise the keyword arguments are used for the query parameters, cutting off the first trailing underscore of the parameter name: >>> href(is_=42) '/foo?is=42' >>> href({'foo': 'bar'}) '/foo?foo=bar' Combining of both methods is not allowed: >>> href({'foo': 'bar'}, bar=42) Traceback (most recent call last): ... TypeError: keyword arguments and query-dicts can't be combined Accessing attributes on the href object creates a new href object with the attribute name as prefix: >>> bar_href = href.bar >>> bar_href("blub") '/foo/bar/blub' If `sort` is set to `True` the items are sorted by `key` or the default sorting algorithm: >>> href = Href("/", sort=True) >>> href(a=1, b=2, c=3) '/?a=1&b=2&c=3' .. versionadded:: 0.5 `sort` and `key` were added. s ./s utf-8c C s7 | s d } n | | _ | | _ | | _ | | _ d S( Ns ./( R� RY Rt Rn ( R R� RY Rt Rn ( ( s< /opt/imh-python/lib/python2.7/site-packages/werkzeug/urls.pyt __init__q s c C sj | d d k r t | � � n | j } | d d k rE | d 7} n t t | | � | j | j | j � S( Ni t __i����R� ( t AttributeErrorR� R� R7 RY Rt Rn ( R t nameR� ( ( s< /opt/imh-python/lib/python2.7/site-packages/werkzeug/urls.pyt __getattr__y s c O sn | rF t | d t � rF | r. t d � � n | d | d } } nS | r� t g | j � D]1 \ } } | j d � r� | d p� | | f ^ q\ � } n d j g | D]- } | d k r� t t | | j � d � ^ q� � j d � } | j } | r&| j d � s| d 7} n t | d | � } n | rd| d t t | | j d | j d | j �d � 7} n t | � S( Ni����s3 keyword arguments and query-dicts can't be combinedt _R� R" s ./R Rt Rn ( R% t dictR) t itemst endswithR8 R$ R RV RY t lstripR� R7 R� Rt Rn R ( R R R t kt vR� R& ( ( s< /opt/imh-python/lib/python2.7/site-packages/werkzeug/urls.pyt __call__� s$ G C !N( RL RM R[ t FalseR$ R� R� R� ( ( ( s< /opt/imh-python/lib/python2.7/site-packages/werkzeug/urls.pyR� > s 1 (5 R[ t ret werkzeug._compatR R R R R R R R R t werkzeug._internalR R t werkzeug.datastructuresR R t collectionsR t compileR� R� R R� Rb R t objectR RP RX Rm Rw R.
