This support for TLS in TLS is known to be disabled in the stdlib asyncio. This is why you'll probably see an error in the log below. It is possible to enable it via monkeypatching under Python 3.7 or higher. For more details, see: * https://bugs.python.org/issue37179 * https://github.com/python/cpython/pull/28073 You can temporarily patch this as follows: * https://docs.aiohttp.org/en/stable/client_advanced.html#proxy-support * https://github.com/aio-libs/aiohttp/discussions/6044 � )r_ rj )� request_info�urlr �getattrrD rE �RuntimeWarning)r? r r� Zasyncio_supports_tls_in_tlsr@ r@ rA �_warn_about_tls_in_tls s z#TCPConnector._warn_about_tls_in_tls)r r� r� r r> c � s� | � � }ttj| �|��}ylt|j�4 I dH �J y$| jj||||j |j d�I dH }W n t k rr |� � � Y nX W dQ I dH R X W n� t k r� } zt|j|�|�W dd}~X Y n� tk r� } zt|j|�|�W dd}~X Y n� tk �r } z||j|�|�W dd}~X Y nh tk �rp } z>td|j �d|jd�d|j�d|j�pNd� d | �d � �| �W dd} ~ X Y n X |�|� ||fS ) z$Wrap the raw TCP transport with TLS.N)�server_hostnameZssl_handshake_timeoutz2Cannot initialize a TLS-in-TLS connection to host �:�dz4 through an underlying connection to an HTTPS proxy z ssl:�defaultz [�])r� r r� r r r+ r rS r r� Ztotalr� rr r$ r r� r% r r � TypeErrorr r� r� Zconnection_made) r? r r� r� r Z tls_protor Z tls_transportr� Ztype_errr@ r@ rA �_start_tls_connection3 s6 4z"TCPConnector._start_tls_connection)r� r� r� r r> c � s� | � |�}| �|�}|jj}|d k s(t�|j}|d k s:t�tj| j|||d�| j d�} yt� | �I d H } W n` tj k r� dd d�dd�} | � | � � Y n0 t k r� } zt|j| �| �W d d } ~ X Y nX d } �x| D ]�}|d }|d }yN| j| j|||||d |d |d |�r |d nd | j||d � I d H \}}W n* tk �rd } z | } w�W d d } ~ X Y nX |�� �r�|�r�y|�|� W nF tk �r� } z&|�� | j�s�| j�|� | } w�W d d } ~ X Y nX ||fS W | d k �s�t�| �d S )N)r� )rP z$asyncio.Future[List[Dict[str, Any]]])r� r> c S s$ t ttj�� | �� W d Q R X d S )N)r ro rw �CancelledErrorr� )r� r@ r@ rA �drop_exception� s z>TCPConnector._create_direct_connection.<locals>.drop_exceptionr� r� r� r� r� r� ) r� r� r� r� r� r r� r� r )r r r Zraw_hostr� r� rw Z ensure_futurer� rS Zshieldr& Zadd_done_callbackr r r� r r� r� r� �checkr" rr r� r� rm )r? r� r� r� r r r� r� r� Z host_resolvedZhostsr' r� �last_excZhinfoZtranspr� r@ r@ rA r l sb z&TCPConnector._create_direct_connectionc � s� | � |� | �� }i }|jd k r&|j}|jtj |tj< |j}|d k sJt�ttj |||j | j |j d�}| j |g |td�I d H \}} | �� |j�tjd �} | d k r�|�� s�| |jtj< n | |jtj< |�� �r�|r�| �||� tj|_|j|_tj|jd d d d�} t| | | | j �} |� | �I d H } �zdy4| j }|d k �s<t�|j |d� | � | �I d H }W n* t k �r� | �!� | �!� � Y �nX d | _ d | _"z�yv|j#dk�r�|j$}|d k�r�t%|j# d }t&| j'|j(|j#||jd��|�s|j)dd d �}|d k�r t*d ��|�+� }W n t k �r* |�!� � Y nX W d |�s>|�!� X |�sp| �,|�}| j-| j.||||j/|d �I d H S | j0|||d �I d H S W d | �!� X || fS ) N)�headers�authrP r� )r )r� � proxy_authZproxy_headers_hash)Zread_until_eof�� r )�statusra r* Zsocket)r" z)Transport does not expose socket instance)r� r� Zsockr r� )r� r� )1r r Z proxy_headersr* r ZHOSTr� r� r' ZMETH_GETr, rS r� r r! r� r� Z AUTHORIZATIONr� ZPROXY_AUTHORIZATIONr Z METH_CONNECT�methodr �attrZevolver� rL �sendrT Zset_response_params�startr� rr rv r. �reasonr0 r r �historyZget_extra_infor �dupr r r� r� r% )r? r� r� r� Zruntime_has_start_tlsr* r Z proxy_reqrk r� r+ rN ZconnZ proxy_resprO Zrespra Zrawsockr r@ r@ rA r� � s� z%TCPConnector._create_proxy_connection)NN)N)4rH rI rJ r~ r/ r| r �bytesr� r r r( r ry r r� r� rw rx rB r rr rz r� r� r� r r r r� r& r� � staticmethodr� � lru_cacher r r r r ro r{ r r r r r Z BaseTransportr% r r� � __classcell__r@ r@ )r� rA r4 � s^ l K ! &9F r4 c sx e Zd ZdZdedddfeeeee df e e e e j dd�� fdd� Zeed �d d ��Zd ed ded�dd�Z� ZS )r5 a� Unix socket connector. path - Unix socket path. keepalive_timeout - (optional) Keep-alive timeout. force_close - Set to True to force close and do reconnect after each request (and between redirects). limit - The total number of simultaneous connections. limit_per_host - Number of simultaneous connections to one host. loop - Optional event loop.
