TCP多线程服务器

两种版本分别应用两种不同的子线程实现方式
版本一

import socket
import threading


def func(tcp_socket):
    while True:

        # 接收信息
        cilent_socket, cilent_addr = tcp_socket.accept()
        print("接收到来自%s的信息" % str(cilent_addr))
        file_name = cilent_socket.recv(1024)
        a = input()
        try:
            file = open(file_name, "rb")
            while True:
                data = file.readline()
                if data:
                    cilent_socket.send(data)
                else:
                    break
        except Exception as error:
            print("文件不存在")
        else:
            file.close()
            print("已发送文件")
            break

        cilent_socket.close()

def main():

    # 创建套接字
    tcp_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    # 设置套接字选项 套接字 选项 重用地址 1代表设置 0代表取消
    tcp_socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
    # 绑定端口
    tcp_socket.bind(("", 8888))
    # 监听
    tcp_socket.listen(128)
    for i in range(100):
        i = threading.Thread(target=func, args=(tcp_socket,))
        i.start()


if __name__ == '__main__':
    main()

版本二

import socket
import threading
tcp_socket = None

    global tcp_socket

    def run(self):
        while True:
            # 接收信息

            print("接收到来自%s的信息" % str(cilent_addr))
            file_name = cilent_socket.recv(1024)

            try:
                file = open(file_name, "rb")
                while True:
                    data = file.readline()
                    if data:
                        cilent_socket.send(data)
                    else:
                        break
            except Exception as error:
                print("文件不存在")
            else:
                file.close()
                print("已发送文件")
                break
            cilent_socket.close()


if __name__ == '__main__':

    # 创建套接字
    tcp_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    # 设置套接字
    tcp_socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
    # 绑定 ip 端口
    tcp_socket.bind(("", 8888))
    # 监听listen
    tcp_socket.listen(128)
    for i in range(100):
        i = MyThread()
        i.start()
