Question

好的，我正在用python3创建一个客户端和服务器，但是每当我尝试比较从客户端接收到的内容时，它都无法正常工作，并返回错误，如最后所示。这是我的服务器的代码（使用线程）：

import socket
import threading

class ThreadedServer(object):
    def __init__(self, host, port):
        self.host = host
        self.port = port
        self.sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        self.sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
        self.sock.bind((self.host, self.port))

def listen(self):
    self.sock.listen(5)
    while True:
        client, address = self.sock.accept()
        client.settimeout(600)
        threading.Thread(target = self.listenToClient,args = (client,address)).start()

def listenToClient(self, client, address):
    size = 1024
    while True:
            data = client.recv(size)
            data = data.decode("utf-8")
            #   Reply 

            if data == "lad":
                response = "nice"
            else:
                response = data



            client.send(response)



if __name__ == "__main__":
    while True:
        host = input("Host? ")
        port_num = input("Port? ")
        try:
            port_num = int(port_num)
            print("Please connect client")            
            break
        except ValueError:
            pass

ThreadedServer(host,port_num).listen()
ThreadedServer(host,port_num).listen()
ThreadedServer.listenToClient()

“数据”是我从客户端收到的。

错误是这样的：

Exception in thread Thread-1:
Traceback (most recent call last):
  File "C:\Python34\lib\threading.py", line 911, in _bootstrap_inner
    self.run()
  File "C:\Python34\lib\threading.py", line 859, in run
    self._target(*self._args, **self._kwargs)
  File "H:\KS4\IT\Computer science\Python\Socketing\AutoServer.py", line 33, in listenToClient
    client.send(response)
TypeError: 'str' does not support the buffer interface

比较套接字中的数据时，Python返回错误
