python中的http客户端无法接收

Question

我正在尝试使用套接字库在 python 中编写 HTTP 客户端，但无法使接收部分正常工作。

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())

问题是我得到的响应是在接收函数内部没有打印的情况下，我什么也没得到，代码只是在等待，我必须强制停止它。

这看起来与Python Recv() stalling 中的问题相同，例如使用 HTTP/1.1 并想知道为什么服务器在请求后没有关闭。有关详细信息，请参见此处。
