소켓 만 사용하여 barebones HTTP/1.1 클라이언트를 구축하려고합니다. Transfer-encoding : chuncked를 사용할 때마다 코드가 다음과 같은 상태를 표시합니다. 502 Bad Gateway.502 전송 인코딩을 사용할 때 게이트웨이가 잘못되었습니다. Python
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
print ("socket successfully created.")
host_ip = socket.gethostbyname('www.google.com')
s.connect((host_ip,80))
op = "GET/HTTP/1.1\r\nHost: www.google.com\r\nTransfer-encoding: chunked\r\nConnection: close\r\n\r\n"
s.sendall(op.encode('utf-8'))
print(s.recv(500000))
s.close()
이 O/P 다음 날주고있다 :
나는 제거하면socket successfully created.

: 헤더를 '전송 인코딩 청크', 그것을 잘 작동합니다.
