當我使用python中的套接字從Google獲取請求時發生錯誤？

我是Socket programming in python的初學者。這是我嘗試的第一個練習，但是我得到403 forbidden error。有人可以指出爲什麼會出現這個錯誤，以及如何解決它？當我使用python中的套接字從Google獲取請求時發生錯誤？

>>> streams = [info for info in socket.getaddrinfo('google.com','http') if info[1]==socket.SOCK_STREAM] 
>>> info=streams[0] 
>>> google_socket=socket.socket(*info[:3]) 
>>> google_socket.connect(info[-1]) 
>>> msg="GET /HTTP/1.1\r\n" 
>>> msg 
'GET /HTTP/1.1\r\n' 
>>> msg+="Host: google.com\r\n\r\n" 
>>> google_socket.sendall(msg) 
>>> buffsize=4096 
>>> response="" 
>>> done=False 
>>> while not done: 
... msg_part=google_socket.recv(buffsize) 
... if len(msg_part)<buffsize: 
...  done=True 
...  google_socket.close() 
... response+=msg_part 
... 
>>> len(response) 
1372 
>>> response

錯誤似乎給你打電話'...但你的電腦或網絡可能正在發送自動查詢......' – AlG

這是一個403錯誤不是404 – Pruthvikar

該錯誤還有[指向Google幫助的鏈接]（ https://support.google.com/websearch/answer/86640）在錯誤消息中。你嘗試閱讀嗎？ – abarnert

您錯誤地指定了HTTP GET請求。試試這個：

>>> msg="GET/HTTP/1.1\r\n"

注/和HTTP之間的空間。
