for testing purposes. It can be used to quickly create WSGI environments

or request objects from arbitrary data.
|
|
|
|
The signature of this class is also used in some other places as of
|
|
Werkzeug 0.5 (:func:`create_environ`, :meth:`BaseResponse.from_values`,
|
|
:meth:`Client.open`). Because of this most of the functionality is
|
|
available through the constructor alone.
|
|
|
|
Files and regular form data can be manipulated independently of each
|
|
other with the :attr:`form` and :attr:`files` attributes, but are
|
|
passed with the same argument to the constructor: `data`.
|
|
|
|
`data` can be any of these values:
|
|
|
|
- a `str`: If it's a string it is converted into a :attr:`input_stream`,
|
|
the :attr:`content_length` is set and you have to provide a
|
|
:attr:`content_type`.
|
|
- a `dict`: If it's a dict the keys have to be strings and the values
|
|
any of the following objects:
|
|
|
|
- a :class:`file`-like object. These are converted into
|
|
:class:`FileStorage` objects automatically.
|
|
- a tuple. The :meth:`~FileMultiDict.add_file` method is called
|
|
with the tuple items as positional arguments.
|
|
|
|
.. versionadded:: 0.6
|
|
`path` and `base_url` can now be unicode strings that are encoded using
|
|
the :func:`iri_to_uri` function.
|
|
|
|
:param path: the path of the request. In the WSGI environment this will
|
|
end up as `PATH_INFO`. If the `query_string` is not defined
|
|
and there is a question mark in the `path` everything after
|
|
it is used as query string.
|
|
:param base_url: the base URL is a URL that is used to extract the WSGI
|
|
URL scheme, host (server name + server port) and the
|
|
script root (`SCRIPT_NAME`).
|
|
:param query_string: an optional string or dict with URL parameters.
|
|
:param method: the HTTP method to use, defaults to `GET`.
|
|
:param input_stream: an optional input stream. Do not specify this and
|
|
`data`. As soon as an input stream is set you can't
|
|
modify :attr:`args` and :attr:`files` unless you
|
|
set the :attr:`input_stream` to `None` again.
|
|
:param content_type: The content type for the request. As of 0.5 you
|
|
don't have to provide this when specifying files
|
|
and form data via `data`.
|
|
:param content_length: The content length for the request. You don't
|
|
have to specify this when providing data via
|
|
`data`.
|
|
:param errors_stream: an optional error stream that is used for
|
|
`wsgi.errors`. Defaults to :data:`stderr`.
|
|
:param multithread: controls `wsgi.multithread`. Defaults to `False`.
|
|
:param multiprocess: controls `wsgi.multiprocess`. Defaults to `False`.
|
|
:param run_once: controls `wsgi.run_once`. Defaults to `False`.
|
|
:param headers: an optional list or :class:`Headers` object of headers.
|
|
:param data: a string or dict of form data. See explanation above.
|
|
:param environ_base: an optional dict of environment defaults.
|
|
:param environ_overrides: an optional dict of environment overrides.
|
|
:param charset: the charset used to encode unicode data.
