This function doesn't verify that the request is an HTTP/1.1 or higher GET request and doesn't perform ``Host`` and ``Origin`` checks. These controls are usually performed earlier in the HTTP request handling code. They're the responsibility of the caller. Args: headers: handshake request headers. Returns: str: ``key`` that must be passed to :func:`build_response`. Raises: InvalidHandshake: if the handshake request is invalid; then the server must return 400 Bad Request error. c �, � g | ]}t |� � ��S � �r ��.0�values r! � <listcomp>z!check_request.<locals>.<listcomp>; �! � �L�L�L�U� �%� � �L�L�Lr" r c 3 �F K � | ] }|� � � d k V � � dS ��upgradeN��lowerr' s r! � <genexpr>z check_request.<locals>.<genexpr>> �/ � � � �B�B�e�u�{�{�}�}� �)�B�B�B�B�B�Br" �, c �, � g | ]}t |� � ��S r% �r r' s r! r* z!check_request.<locals>.<listcomp>B � � �F�F�F�%� �u� � �F�F�Fr" r � r r r Nz,more than one Sec-WebSocket-Key header foundT)�validate� r z0more than one Sec-WebSocket-Version header foundr )�sum�get_all�anyr �join�lenr0 �KeyErrorr r �base64� b64decode�encode�binascii�Errorr )r � connectionr. �s_w_key�exc�raw_key� s_w_versions r! r r & sq � �( *-�L�L�g�o�o�l�.K�.K�L�L�L�b�*� *�J� �B�B�z�B�B�B� B� B� B� �\�4�9�9�Z�+@�+@�A�A�A�%(�F�F�7�?�?�9�+E�+E�F�F�F��&� &�G� ��L�L�A� � �'�!�*�"2�"2�"4�"4� �"C�"C� �Y�� � �'�(:�(:�;�;�;���-�.���� � :� :� :�� /�0�0�c�9����� � � � �� �!O� � �� ��������� H��"�7�>�>�#3�#3�d�C�C�C���� �>� H� H� H� �!4�g�>�>�C�G�����H���� �7�|�|�r��� �!4�g�>�>�>�� � 5�6� � �� � >� >� >�� 3�4�4�#�=����� � � � �� #�%W� � �� ��������� �d��� �!8�+�F�F�F� �Ns` �,C5 �5 D2�?D� D2� D-�-D2�6(E � F�.E?�?F�+F4 �4 G1�>G� G1�G,�,G1r �Nonec �> � d| d< d| d< t |� � | d< dS )z� Build a handshake response to send to the client.
