python--DenyHttp项目--socket编程：客户端与服务器端

Posted 2020-09-29

查找了许多资料，实现了客户端与服务器端的连接，通过虚拟机进行测试

服务器端IP：192.168.37.129 端口1122

客户端IP:　　192.168.37.1　端口1122

Server：

#coding:utf-8
from socket import *
class Dserver():
    def __init__(self):
        self.HOST = ‘192.168.37.129‘
        self.PORT = 1122
        self.BUFSIZE = 1024
        self.ADDR = (self.HOST, self.PORT)
        self.sock = socket(AF_INET, SOCK_STREAM)
        
        self.sock.bind(self.ADDR)
    def listener(self):
        
        self.sock.listen(5)
        
        STOP_CHAT = False
        while not STOP_CHAT:
            print(‘等待接入，侦听端口:%d‘ % (self.PORT))
            topClientSock, addr = self.sock.accept()
            print(‘接受连接，客户端地址：‘,addr[0])
            while True:
                try:
                    data = topClientSock.recv(self.BUFSIZE)
                except:
                    topClientSock.close()
                    print("服务器关闭！")
                    break
                if not data:
                    print("数据为空")
                    break
                s=‘把服务器收到的从%s发送给我的信息:%s 发回来‘ %(addr[0],data.decode(‘utf-8‘))
                print(s)
                topClientSock.send(s.encode(‘utf-8‘))
                
                print(data.decode(‘utf-8‘))
                STOP_CHAT=(data.decode(‘utf-8‘).upper()=="QUIT")
                if STOP_CHAT:
                    break
                
        topClientSock.close()
        self.sock.close()
if __name__ == ‘__main__‘:
    serverDemo = Dserver()
    serverDemo.listener()
            
        

　　Client：

#coding:utf-8
from socket import *
class Dclient():
    def __init__(self):
        self.HOST = ‘192.168.37.129‘
        self.PORT = 1122
        self.BUFSIZE = 1024
        self.ADDR = (self.HOST, self.PORT)
    def listener(self):
        self.client = socket(AF_INET,SOCK_STREAM)
        self.client.connect(self.ADDR)
        
        while True:
            data = input(‘>‘)
            if not data:
                break
            self.client.send(data.encode(‘utf-8‘))
            print(‘发送消息给%s: %s‘ % (self.HOST, data))
            if data.upper() == ‘QUIT‘:
                break
            data = self.client.recv(self.BUFSIZE)
            if not data:
                break
            print(‘接受的消息  %s‘ % (data.decode(‘utf-8‘)))

if __name__ == ‘__main__‘:
    clientDemo = Dclient()
    clientDemo.listener()
