def url_for(endpoint, **values):
    """Generates a URL to the given endpoint with the method provided.

    Variable arguments that are unknown to the target endpoint are appended
    to the generated URL as query arguments.  If the value of a query argument
    is ``None``, the whole pair is skipped.  In case blueprints are active
    you can shortcut references to the same blueprint by prefixing the
    local endpoint with a dot (``.``).

    This will reference the index function local to the current blueprint::

        url_for('.index')

    For more information, head over to the :ref:`Quickstart <url-building>`.

    Configuration values ``APPLICATION_ROOT`` and ``SERVER_NAME`` are only used when
    generating URLs outside of a request context.

    To integrate applications, :class:`Flask` has a hook to intercept URL build
    errors through :attr:`Flask.url_build_error_handlers`.  The `url_for`
    function results in a :exc:`~werkzeug.routing.BuildError` when the current
    app does not have a URL for the given endpoint and values.  When it does, the
    :data:`~flask.current_app` calls its :attr:`~Flask.url_build_error_handlers` if
    it is not ``None``, which can return a string to use as the result of
    `url_for` (instead of `url_for`'s default to raise the
    :exc:`~werkzeug.routing.BuildError` exception) or re-raise the exception.
    An example::

        def external_url_handler(error, endpoint, values):
            "Looks up an external URL when `url_for` cannot build a URL."
            # This is an example of hooking the build_error_handler.
            # Here, lookup_url is some utility function you've built
            # which looks up the endpoint in some external URL registry.
            url = lookup_url(endpoint, **values)
            if url is None:
                # External lookup did not have a URL.
                # Re-raise the BuildError, in context of original traceback.
                exc_type, exc_value, tb = sys.exc_info()
                if exc_value is error:
                    raise exc_type, exc_value, tb
                else:
                    raise error
            # url_for will use this result, instead of raising BuildError.
            return url

        app.url_build_error_handlers.append(external_url_handler)

    Here, `error` is the instance of :exc:`~werkzeug.routing.BuildError`, and
    `endpoint` and `values` are the arguments passed into `url_for`.  Note
    that this is for building URLs outside the current application, and not for
    handling 404 NotFound errors.

    :param endpoint: the endpoint of the URL (name of the function)
    :param values: the variable arguments of the URL rule
    :param _external: if set to ``True``, an absolute URL is generated. Server
      address can be changed via ``SERVER_NAME`` configuration variable which
      falls back to the `Host` header, then to the IP and port of the request.
    :param _scheme: a string specifying the desired URL scheme. The `_external`
      parameter must be set to ``True`` or a :exc:`ValueError` is raised. The default
      behavior uses the same scheme as the current request, or
      ``PREFERRED_URL_SCHEME`` from the :ref:`app configuration <config>` if no
      request context is available. As of Werkzeug 0.10, this also can be set

    """Sends the contents of a file to the client.  This will use the
    most efficient method available and configured.  By default it will
    try to use the WSGI server's file_wrapper support.  Alternatively
    you can set the application's :attr:`~Flask.use_x_sendfile` attribute
    to ``True`` to directly emit an ``X-Sendfile`` header.  This however
    requires support of the underlying webserver for ``X-Sendfile``.

    By default it will try to guess the mimetype for you, but you can
    also explicitly provide one.  For extra security you probably want
    to send certain files as attachment (HTML for instance).  The mimetype
    guessing requires a `filename` or an `attachment_filename` to be
    provided.

    ETags will also be attached automatically if a `filename` is provided. You
    can turn this off by setting `add_etags=False`.

    If `conditional=True` and `filename` is provided, this method will try to
    upgrade the response stream to support range requests.  This will allow
    the request to be answered with partial content response.

    Please never pass filenames to this function from user sources;
    you should use :func:`send_from_directory` instead.

    .. versionadded:: 0.2

    .. versionadded:: 0.5
       The `add_etags`, `cache_timeout` and `conditional` parameters were
       added.  The default behavior is now to attach etags.

    .. versionchanged:: 0.7
       mimetype guessing and etag support for file objects was
       deprecated because it was unreliable.  Pass a filename if you are
       able to, otherwise attach an etag yourself.  This functionality
       will be removed in Flask 1.0

    .. versionchanged:: 0.9
       cache_timeout pulls its default from application config, when None.

    .. versionchanged:: 0.12
       The filename is no longer automatically inferred from file objects. If
       you want to use automatic mimetype and etag support, pass a filepath via
       `filename_or_fp` or `attachment_filename`.

    .. versionchanged:: 0.12
       The `attachment_filename` is preferred over `filename` for MIME-type
       detection.

    .. versionchanged:: 0.13
        UTF-8 filenames, as specified in `RFC 2231`_, are supported.

                           back to the traditional method.  Make sure that the

                           send before calling :func:`send_file`.
    :param mimetype: the mimetype of the file if provided. If a file path is
                     given, auto detection happens as fallback, otherwise an
                     error will be raised.

                          a ``Content-Disposition: attachment`` header.

                                differs from the file's filename.
    :param add_etags: set to ``False`` to disable attaching of etags.
    :param conditional: set to ``True`` to enable conditional responses.

    :param cache_timeout: the timeout in seconds for the headers. When ``None``
                          (default), this value is set by

    Variable arguments that are unknown to the target endpoint are appended
    to the generated URL as query arguments.  If the value of a query argument
    is `None`, the whole pair is skipped.  In case blueprints are active
    you can shortcut references to the same blueprint by prefixing the
    local endpoint with a dot (``.``).

    This will reference the index function local to the current blueprint::

        url_for('.index')

    For more information, head over to the :ref:`Quickstart <url-building>`.

    To integrate applications, :class:`Flask` has a hook to intercept URL build
    errors through :attr:`Flask.build_error_handler`.  The `url_for` function
    results in a :exc:`~werkzeug.routing.BuildError` when the current app does
    not have a URL for the given endpoint and values.  When it does, the
    :data:`~flask.current_app` calls its :attr:`~Flask.build_error_handler` if
    it is not `None`, which can return a string to use as the result of
    `url_for` (instead of `url_for`'s default to raise the
    :exc:`~werkzeug.routing.BuildError` exception) or re-raise the exception.
    An example::

        def external_url_handler(error, endpoint, **values):
            "Looks up an external URL when `url_for` cannot build a URL."
            # This is an example of hooking the build_error_handler.
            # Here, lookup_url is some utility function you've built
            # which looks up the endpoint in some external URL registry.
            url = lookup_url(endpoint, **values)
            if url is None:
                # External lookup did not have a URL.
                # Re-raise the BuildError, in context of original traceback.

            return url

        app.build_error_handler = external_url_handler

    Here, `error` is the instance of :exc:`~werkzeug.routing.BuildError`, and
    `endpoint` and `**values` are the arguments passed into `url_for`.  Note
    that this is for building URLs outside the current application, and not for

    .. warning::

        It is very easy to be exposed to Cross-Site Scripting (XSS) attacks if
        you serve user uploaded files. Here are some recommendations:

            1. Serve user uploaded files from a separate domain
               (not a subdomain). This way a malicious file can only attack
               other user uploaded files.
            2. Prevent the browser from rendering and executing HTML files (by
               setting ``trusted=False``).
            3. Force the browser to download the file as an attachment
               (``as_attachment=True``).

    :param stream: The file stream to send.
    :param filename: The file name.
    :param size: The file size.
    :param mtime: A Unix timestamp that represents last modified time (UTC).
    :param mimetype: The file mimetype. If ``None``, the module will try to
        guess. (Default: ``None``)
    :param restricted: If the file is not restricted, the module will set the
        cache-control. (Default: ``True``)
    :param as_attachment: If the file is an attachment. (Default: ``False``)
    :param etag: If defined, it will be set as HTTP E-Tag.
    :param content_md5: If defined, a HTTP Content-MD5 header will be set.
    :param chunk_size: The chunk size.
    :param conditional: Make the response conditional to the request.
        (Default: ``True``)
    :param trusted: Do not enable this option unless you know what you are
        doing. By default this function will send HTTP headers and MIME types
        that prevents your browser from rendering e.g. a HTML file which could
        contain a malicious script tag.

    """Sends the contents of a file to the client.  This will use the
    most efficient method available and configured.  By default it will
    try to use the WSGI server's file_wrapper support.  Alternatively
    you can set the application's :attr:`~Flask.use_x_sendfile` attribute
    to ``True`` to directly emit an ``X-Sendfile`` header.  This however
    requires support of the underlying webserver for ``X-Sendfile``.

    By default it will try to guess the mimetype for you, but you can
    also explicitly provide one.  For extra security you probably want
    to send certain files as attachment (HTML for instance).  The mimetype
    guessing requires a `filename` or an `attachment_filename` to be
    provided.

    When passing a file-like object instead of a filename, only binary
    mode is supported (``open(filename, "rb")``, :class:`~io.BytesIO`,
    etc.). Text mode files and :class:`~io.StringIO` will raise a
    :exc:`ValueError`.

    ETags will also be attached automatically if a `filename` is provided. You
    can turn this off by setting `add_etags=False`.

    If `conditional=True` and `filename` is provided, this method will try to
    upgrade the response stream to support range requests.  This will allow
    the request to be answered with partial content response.

    Please never pass filenames to this function from user sources;
    you should use :func:`send_from_directory` instead.

    .. 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.

    .. 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.

    .. _RFC 2231: https://tools.ietf.org/html/rfc2231#section-4

    .. 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
       deprecated because it was unreliable. Pass a filename if you are
       able to, otherwise attach an etag yourself. This functionality
       will be removed in Flask 1.0.

    .. versionadded:: 0.5
       The ``add_etags``, ``cache_timeout`` and ``conditional``
       parameters were added. The default behavior is to add etags.

    .. versionadded:: 0.2

    :param filename_or_fp: The filename of the file to send, relative to
        :attr:`~Flask.root_path` if a relative path is specified.
        Alternatively, a file-like object opened in binary mode. Make
        sure the file pointer is seeked to the start of the data.
        ``X-Sendfile`` will only be used with filenames.
    :param mimetype: the mimetype of the file if provided. If a file path is
                     given, auto detection happens as fallback, otherwise an
                     error will be raised.
    :param as_attachment: set to ``True`` if you want to send this file with
                          a ``Content-Disposition: attachment`` header.
    :param attachment_filename: the filename for the attachment if it
                                differs from the file's filename.
    :param add_etags: set to ``False`` to disable attaching of etags.
    :param conditional: set to ``True`` to enable conditional responses.

    :param cache_timeout: the timeout in seconds for the headers. When ``None``
                          (default), this value is set by
                          :meth:`~Flask.get_send_file_max_age` of
                          :data:`~flask.current_app`.
    :param last_modified: set the ``Last-Modified`` header to this value,
        a :class:`~datetime.datetime` or timestamp.
        If a file was passed, this overrides its mtime.
