Question

HTTP要求を作成し、解析されていない未処理の応答（特にヘッダー）を取得する簡単な方法はありますか？

Answer 1

直接socketモジュールを使用する：

import socket 

CRLF = "\r\n" 

request = [ 
    "GET/HTTP/1.1", 
    "Host: www.example.com", 
    "Connection: Close", 
    "", 
    "", 
] 

# Connect to the server 
s = socket.socket() 
s.connect(('www.example.com', 80)) 

# Send an HTTP request 
s.send(CRLF.join(request)) 

# Get the response (in several parts, if necessary) 
response = '' 
buffer = s.recv(4096) 
while buffer: 
    response += buffer 
    buffer = s.recv(4096) 

# HTTP headers will be separated from the body by an empty line 
header_data, _, body = response.partition(CRLF + CRLF) 

print header_data 

HTTP/1.0 302 Found
