Python中的HTTP客户端未能接收
我正在尝试用Python的sockets库写一个HTTP客户端，但接收部分一直无法正常工作。
这是我的代码：
import socket, sys
class httpBase:
def __init__(self, host, port=80):
self.s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
self.s.connect((host, port))
def send(self, msg):
self.s.sendall(msg)
def recive(self):
data = ''
while 1:
Tdata = self.s.recv(128)
print("||" + data + "|")
data += Tdata
if data.decode() == '': break
return data
http = httpBase('www.google.com')
http.send('GET / HTTP/1.1\r\n\r\n'.encode())
print(http.recive())
问题是，如果我在接收函数里面不加打印语句，我就什么都收不到，代码就一直在等待，我只能强制停止它。
这是我从谷歌得到的响应：
