python使用socket模块实现TCP高并发任务

python 复制代码

from threading import Thread
import socket


class HandelParse(Thread):
    def __init__(self,socket_obj):
        super().__init__()
        self.socket_obj = socket_obj

    def run(self):
        while True:
            recv_msg = self.socket_obj.recv(1024)
            if len(recv_msg)!=0:
                print(recv_msg.decode("utf-8"))
                self.socket_obj.send(recv_msg) #再次原路发回去。注tcp用send方法，udp用sendto方法
            else:
                self.socket_obj.close()
                break


class TcpServer(Thread):
    def __init__(self):
        super().__init__()
        self.tcp_sercer = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
        self.tcp_sercer.bind(("",7878))
        self.tcp_sercer.listen(128) #设置监听数量

    def run(self):
        while True:
            msg,client_info = self.tcp_sercer.accept() #等待连接
            #创建子线程，实现多并发
            handel_data_thread = HandelParse(msg)
            handel_data_thread.start()

    def __del__(self):
        self.tcp_sercer.close()


if __name__ == '__main__':
    tcp = TcpServer()
    tcp.start()

使用网络调试工具测试。同时开通3 个调试助手软件进行连接。截图如下：

多线程实socket编程

from threading import Thread
from queue import Queue
import socket


class RecvUdp(Thread):
    def __init__(self,udp:socket.socket,q:Queue):
        super().__init__()
        self.udp = udp
        self.q: Queue = q

    def run(self):
        while True:
            msg,client_info = self.udp.recvfrom(1024)
            contect=f'>>>ip:{client_info[0]},port:{client_info[1]} 内容：{msg.decode("utf-8")}'
            self.q.put(contect)

    def __del__(self):
        self.udp.close()


class SendUdp(Thread):
    def __init__(self,udp:socket.socket,q):
        super().__init__()
        self.udp = udp
        self.q: Queue = q

    def run(self):
        while True:
            desp_ip = input("请输入对方ip")
            desp_port = int(input("请输入对方端口:"))
            while True:
                content = input("请输入内容")
                if content :
                    self.udp.sendto(content.encode("utf-8"),(desp_ip,desp_port))
                    msg = f"<<<发送ip:{desp_ip}，port:{desp_port},信息：{content}"
                    self.q.put(msg)
                else:
                    break
    def __del__(self):
        self.udp.close()

class ChatHistory(Thread):
    def __init__(self,q:Queue):
        super().__init__()
        self.q :Queue = q

    def run(self):
        while True:
            data = self.q.get()
            with open("./chathistory.txt",'a',encoding='utf-8') as f:
                f.write(data)
                f.write("\n")



def main():
    udp = socket.socket(socket.AF_INET,socket.SOCK_DGRAM)
    udp.bind(("127.0.0.1",650))
    q = Queue()

    #创建一个接受线程
    recv_msg_thread =RecvUdp(udp,q)
    #线程
    recv_msg_thread.start()

    #发送线程
    send_msg_thread = SendUdp(udp,q)
    send_msg_thread.start()

    #quen

    chat_thread =ChatHistory(q)
    chat_thread.start()

main()
