Python学习笔记之：使用Python面向对象的方式写一个基于TCP的简单客户端和服务端聊天器

简单：只实现一条消息的收发

1.客户端

import socket

class tcpClient():

    def __init__(self,server_ip,server_port):
        self.tcp_socket = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
        self.address = self.tcp_socket.bind(("",8080))
        self.server_ip = server_ip
        self.server_port = int(server_port)
        self.tcp_socket.connect((self.server_ip,self.server_port))

    def send(self,content):

        self.tcp_socket.send(content.encode("gbk"))


if __name__ == '__main__':

    tcp_client = tcpClient("192.168.1.239",8084)
    content = input(">>>")
    tcp_client.send(content)

2. 服务端

import socket

class tcpServer():

    def __init__(self):

        self.tcp_server_socket = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
        self.address = self.tcp_server_socket.bind(("192.168.1.239",8084))
        self.tcp_server_socket.listen()
        self.new_client_info, self.new_ip_port = self.tcp_server_socket.accept()
        self.bufsize = 1024

    def recv(self):
        data = self.new_client_info.recv(self.bufsize).decode("gbk")
        return data

if __name__ == '__main__':

    tcp_server = tcpServer()
    data = tcp_server.recv()
    print(data)

进阶：进行多条消息的收发

1.客户端

import socket

class tcpClient():

    def __init__(self,server_ip,server_port):
        self.tcp_socket = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
        self.address = self.tcp_socket.bind(("",8080))
        self.server_ip = server_ip
        self.server_port = int(server_port)
        self.tcp_socket.connect((self.server_ip,self.server_port))

    def send(self,content):

        self.tcp_socket.send(content.encode("gbk"))

    def close_socket(self):
        self.tcp_socket.close()


if __name__ == '__main__':
    tcp_client = tcpClient("192.168.1.239", 8084)
    while True:
        content = input(">>>")
        if content:
            tcp_client.send(content)
        else:
            tcp_client.close_socket()

2.服务端

import socket

class tcpServer():

    def __init__(self):

        self.tcp_server_socket = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
        self.address = self.tcp_server_socket.bind(("192.168.1.239",8084))
        self.tcp_server_socket.setsockopt(socket.SOL_SOCKET,socket.SO_REUSEADDR,True)
        self.tcp_server_socket.listen()
        self.new_client_info = None
        self.new_ip_port = None
        self.bufsize = 1024
        self.data = None

    def accept(self):
        self.new_client_info, self.new_ip_port = self.tcp_server_socket.accept()
        return self.new_client_info,self.new_ip_port

    def recv_message(self):
        self.data = self.new_client_info.recv(self.bufsize).decode("gbk")
        return self.data

    def close_socket(self):
        self.tcp_server_socket.close()


if __name__ == '__main__':

    tcp_server = tcpServer()
    while True:
        new_client_info, new_ip_port = tcp_server.accept()
        while True:
            data = tcp_server.recv_message()
            if data:
                print(data)
                # new_client_info.close()
            else:
                new_client_info.close()
                print("服务器正在退出···")
                break
        tcp_server.close_socket()
