Has properties and methods for using the functionality defined by various HTTP specs. The response body is flexible to support different use cases. The simple form is passing bytes, or a string which will be encoded as UTF-8. Passing an iterable of bytes or strings makes this a streaming response. A generator is particularly useful for building a CSV file in memory or using SSE (Server Sent Events). A file-like object is also iterable, although the :func:`~werkzeug.utils.send_file` helper should be used in that case. The response object is itself a WSGI application callable. When called (:meth:`__call__`) with ``environ`` and ``start_response``, it will pass its status and headers to ``start_response`` then return its body as an iterable. .. code-block:: python from werkzeug.wrappers.response import Response def index(): return Response("Hello, World!") def application(environ, start_response): path = environ.get("PATH_INFO") or "/" if path == "/": response = index() else: response = Response("Not Found", status=404) return response(environ, start_response) :param response: The data for the body of the response. A string or bytes, or tuple or list of strings or bytes, for a fixed-length response, or any other iterable of strings or bytes for a streaming response. Defaults to an empty body. :param status: The status code for the response. Either an int, in which case the default status message is added, or a string in the form ``{code} {message}``, like ``404 Not Found``. Defaults to 200. :param headers: A :class:`~werkzeug.datastructures.Headers` object, or a list of ``(key, value)`` tuples that will be converted to a ``Headers`` object. :param mimetype: The mime type (content type without charset or other parameters) of the response. If the value starts with ``text/`` (or matches some other special cases), the charset will be added to create the ``content_type``. :param content_type: The full content type of the response. Overrides building the value from ``mimetype``. :param direct_passthrough: Pass the response body directly through as the WSGI iterable. This can be used when the body is a binary file or other iterator of bytes, to skip some unnecessary checks. Use :func:`~werkzeug.utils.send_file` instead of setting this manually. .. versionchanged:: 2.0 Combine ``BaseResponse`` and mixins into a single ``Response`` class. Using the old classes is deprecated and will be removed in Werkzeug 2.1. .. versionchanged:: 0.5 The ``direct_passthrough`` parameter was added.

Werkzeug will use the :class:`Response` internally in many situations like the exceptions. If you call :meth:`get_response` on an exception you will get back a regular :class:`Response` object, even if you are using a custom subclass. This method can enforce a given response type, and it will also convert arbitrary WSGI callables into response objects if an environ is provided:: # convert a Werkzeug response object into an instance of the # MyResponseClass subclass. response = MyResponseClass.force_type(response) # convert any WSGI application into a response object response = MyResponseClass.force_type(response, environ) This is especially useful if you want to post-process responses in the main dispatcher and use functionality provided by your subclass. Keep in mind that this will modify response objects in place if possible! :param response: a response object or wsgi application. :param environ: a WSGI environment object. :return: a response object.

This works best if you pass it an application that returns a generator all the time. Sometimes applications may use the `write()` callable returned by the `start_response` function. This tries to resolve such edge cases automatically. But if you don't get the expected output you should set `buffered` to `True` which enforces buffering. :param app: the WSGI application to execute. :param environ: the WSGI environment to execute against. :param buffered: set to `True` to enforce buffering. :return: a response object. r rM )rP rN )rQ rS rL rT rN r! r! r" �from_app s zResponse.from_appzte.Literal[False])�as_textr c C s d S r% r! �r9 rV r! r! r" �get_data! s zResponse.get_datazte.Literal[True]c C s d S r% r! rW r! r! r" rX % s c C s* | � � d�| �� �}|r&|�| j�S |S )a� The string representation of the response body. Whenever you call this property the response iterable is encoded and flattened. This can lead to unwanted behavior if you stream big data.

Also the content length is automatically set to zero here for certain status codes. .. versionchanged:: 0.6 Previously that function was called `fix_headers` and modified the response object in place. Also since 0.6, IRIs in location and content-location headers are handled properly. Also starting with 0.6, Werkzeug will attempt to set the content length if it is able to figure it out on its own. This is the case if all the strings in the response iterable are already encoded and the iterable is buffered. :param environ: the WSGI environment of the request. :return: returns a new :class:`~werkzeug.datastructures.Headers` object.

This method works best if an etag was defined for the response already. The `add_etag` method can be used to do that. If called without etag just the date header is set. This does nothing if the request method in the request or environ is anything but GET or HEAD. For optimal performance when handling range requests, it's recommended that your response data object implements `seekable`, `seek` and `tell` methods as described by :py:class:`io.IOBase`. Objects returned by :meth:`~werkzeug.wsgi.wrap_file` automatically implement those methods. It does not remove the body of the response because that's something the :meth:`__call__` function does for us automatically. Returns self so that you can do ``return resp.make_conditional(req)`` but modifies the object in-place. :param request_or_environ: a request object or WSGI environment to be used to make the response conditional against. :param accept_ranges: This parameter dictates the value of `Accept-Ranges` header. If ``False`` (default), the header is not set. If ``True``, it will be set to ``"bytes"``. If ``None``, it will be set to ``"none"``. If it's a string, it will use this value. :param complete_length: Will be used only in valid Range Requests. It will set `Content-Range` complete length value and compute `Content-Length` real value. This parameter is mandatory for successful Range Requests completion. :raises: :class:`~werkzeug.exceptions.RequestedRangeNotSatisfiable` if `Range` header could not be parsed or satisfied. .. versionchanged:: 2.0 Range processing is skipped if length is 0 instead of raising a 416 Range Not Satisfiable error. r� )�GETr� �date�Dater� Nr� Z HTTP_IF_MATCHi� r� r~ r` ) r r0 r r- r� r r� r r� ra rj )r9 r� r) r� rL Zis206r� r! r! r" �make_conditional� s. . ��� zResponse.make_conditional)� overwrite�weakr c C s& |sd| j vr"| �t| �� �|� dS )z�Add an etag for the current response if there is none yet. .. versionchanged:: 2.0 SHA-1 is used to generate the value.
