我们从Python开源项目中，提取了以下50个代码示例，用于说明如何使用werkzeug._internal._get_environ()。
def make_conditional(self, request_or_environ): """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. It does not remove the body of the response because that's something the :meth:`__call__` function does for us automatically.
