python - 来自谷歌的 400 错误请求

每次当我尝试拉取 google.com 时，它只会响应 400 Bad Request。尝试将\n\n 更改为\r\n 但仍然是同样的问题。由于它的 HTTP 错误，我认为套接字没有问题。

import socket
import ssl

socks = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
SSLSocks = ssl.wrap_socket(socks)
ip = socket.gethostbyname('google.com')
request = "GET / HTTPS/1.1\n"
request += "Host: " + ip + "\n\n"
#request += "Content-Type: application/json\r\n"
#request += "Connection: close"+"\r\n"

SSLSocks.connect((ip,443))
SSLSocks.send(request.encode())
result = SSLSocks.recv(4096)
print(ip)
print(result)

输出:

172.217.163.142

最佳答案

修复代码:

  1. 协议(protocol)仍然是HTTP
  2. 你需要用\r\n结束每一行

上下文管理器也有很大帮助，似乎主要由 micropython 支持

import socket
import ssl

host = 'www.google.com'

request = "GET / HTTP/1.1\r\n"
request += "Host: " + host + "\r\n"
request += "Content-Type: application/json\r\n"
request += "Connection: close\r\n"
request += "\r\n"

with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as sock:
    sock = ssl.wrap_socket(sock)
    sock.connect((host, 443))
    peer = sock.getpeername()
    sock.send(request.encode())
    result = sock.recv(4096)
    sock.close()

print(peer)
print(result)
