Because views do not have to return response objects but can return a value that is converted into a response object by Flask itself, it becomes tricky to add headers to it. This function can be called instead of using a return and you will get a response object which you can use to attach headers. If view looked like this and you want to add a new header:: def index(): return render_template('index.html', foo=42) You can now do something like this:: def index(): response = make_response(render_template('index.html', foo=42)) response.headers['X-Parachutes'] = 'parachutes are cool' return response This function accepts the very same arguments you can return from a view function. This for example creates a response with a 404 error code:: response = make_response(render_template('not_found.html'), 404) The other use case of this function is to force the return value of a view function into a response which is helpful with view decorators:: response = make_response(view_function()) response.headers['X-Parachutes'] = 'parachutes are cool' Internally this function does the following things: - if no arguments are passed, it creates a new response argument - if one argument is passed, :meth:`flask.Flask.make_response` is invoked with it. - if more than one argument is passed, the arguments are passed to the :meth:`flask.Flask.make_response` function as tuple. .. versionadded:: 0.6 r r)r response_classlen make_response)r2s rrFrFsET ,)+++ 4yyA~~Aw  $T * **r _anchor_method_scheme _externalendpointstrrH str | NonerIrJrK bool | Nonevaluesc 0tj|f||||d|S)aGenerate a URL to the given endpoint with the given values.

Further calls in the same request to the function will return the same messages.

Filter the flashed messages to one or more categories by providing those categories in `category_filter`. This allows rendering categories in separate html blocks. The `with_categories` and `category_filter` arguments are distinct: * `with_categories` controls whether categories are returned with message text (``True`` gives a tuple, where ``False`` gives just the message text). * `category_filter` filters the messages down to only those matching the provided categories.

The first argument can be a file path or a file-like object. Paths are preferred in most cases because Werkzeug can manage the file and get extra information from the path. Passing a file-like object requires that the file is opened in binary mode, and is mostly useful when building a file in memory with :class:`io.BytesIO`. Never pass file paths provided by a user. The path is assumed to be trusted, so a user could craft a path to access a file you didn't intend. Use :func:`send_from_directory` to safely serve user-requested paths from within a directory. If the WSGI server sets a ``file_wrapper`` in ``environ``, it is used, otherwise Werkzeug's built-in wrapper is used. Alternatively, if the HTTP server supports ``X-Sendfile``, configuring Flask with ``USE_X_SENDFILE = True`` will tell the server to send the given path, which is much more efficient than reading it in Python. :param path_or_file: The path to the file to send, relative to the current working directory if a relative path is given. Alternatively, a file-like object opened in binary mode. Make sure the file pointer is seeked to the start of the data. :param mimetype: The MIME type to send for the file. If not provided, it will try to detect it from the file name. :param as_attachment: Indicate to a browser that it should offer to save the file instead of displaying it. :param download_name: The default name browsers will use when saving the file. Defaults to the passed file name. :param conditional: Enable conditional and range responses based on request headers. Requires passing a file path and ``environ``. :param etag: Calculate an ETag for the file, which requires passing a file path. Can also be a string to use instead. :param last_modified: The last modified time to send for the file, in seconds. If not provided, it will try to detect it from the file path. :param max_age: How long the client should cache the file, in seconds. If set, ``Cache-Control`` will be ``public``, otherwise it will be ``no-cache`` to prefer conditional caching. .. versionchanged:: 2.0 ``download_name`` replaces the ``attachment_filename`` parameter. If ``as_attachment=False``, it is passed with ``Content-Disposition: inline`` instead. .. versionchanged:: 2.0 ``max_age`` replaces the ``cache_timeout`` parameter. ``conditional`` is enabled and ``max_age`` is not set by default. .. versionchanged:: 2.0 ``etag`` replaces the ``add_etags`` parameter. It can be a string to use instead of generating one. .. versionchanged:: 2.0 Passing a file-like object that inherits from :class:`~io.TextIOBase` will raise a :exc:`ValueError` rather than sending an empty file. .. versionadded:: 2.0 Moved the implementation to Werkzeug. This is now a wrapper to pass some Flask-specific arguments. .. versionchanged:: 1.1 ``filename`` may be a :class:`~os.PathLike` object. .. versionchanged:: 1.1 Passing a :class:`~io.BytesIO` object supports range requests. .. versionchanged:: 1.0.3 Filenames are encoded with ASCII instead of Latin-1 for broader compatibility with WSGI servers. .. versionchanged:: 1.0 UTF-8 filenames as specified in :rfc:`2231` are supported. .. versionchanged:: 0.12 The filename is no longer automatically inferred from file objects. If you want to use automatic MIME and etag support, pass a filename via ``filename_or_fp`` or ``attachment_filename``. .. versionchanged:: 0.12 ``attachment_filename`` is preferred over ``filename`` for MIME detection. .. versionchanged:: 0.9 ``cache_timeout`` defaults to :meth:`Flask.get_send_file_max_age`. .. versionchanged:: 0.7 MIME guessing and etag support for file-like objects was removed because it was unreliable. Pass a filename if you are able to, otherwise attach an etag yourself. .. versionchanged:: 0.5 The ``add_etags``, ``cache_timeout`` and ``conditional`` parameters were added.
