我们从Python开源项目中，提取了以下34个代码示例，用于说明如何使用werkzeug.exceptions.RequestedRangeNotSatisfiable()。
def _process_range_request(self, environ, complete_length=None, accept_ranges=None): """Handle Range Request related headers (RFC7233). If `Accept-Ranges` header is valid, and Range Request is processable, we set the headers as described by the RFC, and wrap the underlying response in a RangeWrapper. Returns ``True`` if Range Request can be fulfilled, ``False`` otherwise. :raises: :class:`~werkzeug.exceptions.RequestedRangeNotSatisfiable` if `Range` header could not be parsed or satisfied. """ from werkzeug.exceptions import RequestedRangeNotSatisfiable if accept_ranges is None: return False self.headers['Accept-Ranges'] = accept_ranges if not self._is_range_request_processable(environ) or complete_length is None: return False parsed_range = parse_range_header(environ.get('HTTP_RANGE')) if parsed_range is None: raise RequestedRangeNotSatisfiable(complete_length) range_tuple = parsed_range.range_for_length(complete_length) content_range_header = parsed_range.to_content_range_header(complete_length) if range_tuple is None or content_range_header is None: raise RequestedRangeNotSatisfiable(complete_length) content_length = range_tuple[1] - range_tuple[0] # Be sure not to send 206 response # if requested range is the full content. if content_length != complete_length: self.headers['Content-Length'] = content_length self.content_range = content_range_header self.status_code = 206 self._wrap_response(range_tuple[0], content_length) return True return False
def make_conditional(self, request_or_environ, accept_ranges=False, complete_length=None): """Make the response conditional to the request. 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.

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.
