python - python多个客户端聊天不起作用

Question

当我运行main和client的py文件时，未显示错误，但未显示发送消息的输入。怎么修？
main.py结果->等待中...并已连接192.168.1.26 58767
client.py结果->没有
这是main.py

import threading
import socket

server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)

host="192.168.1.26"
port=1111
threadcount=0
server.bind((host,port))
print("Waiting...")
server.listen(3)


def clients(connection):
    connection.send(str.encode("welcome\n"))
    while True:
        data=connection.recv(2048)
        reply="server says" + data.decode("utf-8")
        if not data:
            break
        connection.sendall(str.encode(reply))
    connection.close()

while True:
    client,adress=server.accept()
    print("connected"+ str(adress[0]) + " " + str(adress[1]))
    threading.Thread(target=clients,args=(client,))
    threadcount+=1
server.close()

这是clients.py

import socket

client_socket=socket.socket()
host="192.168.1.26"
port=1111
client_socket.connect((host,port))

response=client_socket.recv(1024)
print("hello")

while True:
    input=input("say")
    client_socket.send(str.encode(input))
    Response=client_socket.recv(1024)
    print(Response.decode("utf-8"))

client_socket.close()

看来您的线程从未真正启动过。一种解决方案是定义一个在run例程中实现线程逻辑的类。该类应继承threading.Thread。然后，您可以简单地将类初始化为对象并调用其start例程。请尝试以下原始服务器代码的变体。

import threading
import socket

server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)

host="192.168.1.26"
port=1111
threadcount=0
server.bind((host,port))
print("Waiting...")
server.listen(3)

class ServerThread(threading.Thread):
    def __init__(self, threadsocket):
        threading.Thread.__init__(self)
        self.threadsocket = threadsocket

    def run(self):
        self.threadsocket.send(str.encode("welcome\n"))
        while True:
            data=self.threadsocket.recv(2048)
            reply="server says" + data.decode("utf-8")
            print(reply)
            if not data:
                break
            self.threadsocket.sendall(str.encode(reply))
        self.threadsocket.close()

while True:
    client,adress=server.accept()
    print("connected"+ str(adress[0]) + " " + str(adress[1]))
    thread = ServerThread(client)
    thread.start()
    threadcount+=1

server.close()

就客户端而言，正如我在评论中提到的那样，您不应将 input用作变量名称来存储 input函数的结果。改为将其更改为 data。
