python - HTTP/1.1 与 HTTP/1.0 Python 套接字

Question

我正在尝试使用 Python 套接字发送和接收 HTTP 数据。但是当我使用 HTTP/1.0 时它可以工作，但是当我使用 HTTP/1.1 时它只是一直等待......

此代码有效

import socket

client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_address = ('httpbin.org', 80)
client_socket.connect(server_address)

request_header = 'GET /ip HTTP/1.0\r\nHost: httpbin.org\r\n\r\n'
client_socket.send(request_header.encode())

response = ''
while True:
    recv = client_socket.recv(1024)
    if not recv:
        break
    response += recv 

print(response)
client_socket.close()

这不起作用

import socket

client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_address = ('httpbin.org', 80)
client_socket.connect(server_address)

request_header = 'GET /ip HTTP/1.1\r\nHost: httpbin.org\r\n\r\n'
client_socket.send(request_header.encode())

response = ''
while True:
    recv = client_socket.recv(1024)
    if not recv:
        break
    response += recv 

print(response)
client_socket.close() 

如果 HTTP/1.1 是问题所在，那么我如何检测它是否不支持 HTTP/1.1？

Answer 1

HTTP/1.1 默认为持久连接。如果您希望服务器在发送响应后关闭连接，则需要发送 Connection: close header 。

request_header = 'GET /ip HTTP/1.1\r\nHost: httpbin.org\r\nConnection: close\r\n\r\n'
