Question

我尝试创建一个简单的客户端和一个使用线程的服务器。但有时我的服务器会输出错误：文件描述符错误。我在网上看到同样的问题和解决问题的解决方案。但最后，我没有成功解决我的问题。所以，如果您有任何想法如何解决问题，它将是优雅的。谢谢！

我的代码：

import socket               # Import socket module
from threading import Thread

# Global Variable


class ThreadServer:
    def __init__(self, host, port):
        try:
            self.host = host
            self.port = port
            self.sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
            self.sock.bind((self.host, self.port))
            print "Server Start successfully !"
        except Exception as e:
            print "Something wrong %s" % (e)

    def listen(self):
        self.sock.listen(3)  # Waiting for n client
        while True:
            client, address = self.sock.accept()  # Establish connection with clients
            client.settimeout(60)
            Thread(target=self.listen_for_client, args=(client, address)).start()

    def listen_for_client(self, client, address):
        print "Got connection from",  address
        while True:
            try:
                msg = client.recv(1024)
                if msg[0:4] == "USER":
                    user = msg[4:]
                    self.write_new_clients(address, user)
                    msg = 0
                if msg:
                    print msg
                    client.send("Server : " + msg)
            except Exception as e:
                print "Something wrong %s" % (e)
                client.close()

    def write_new_clients(self, address, user):
        my_file = open("Clients_list.txt", "a+")
        line = my_file.readline()
        for i in line:
            if str(address) in line:
                print "Already Exist !"
            else:
                my_file.write(str(user) +"::" + str(address)  + "\n")


def main():
    ThreadServer("0.0.0.0", 8350).listen()


if __name__ == "__main__":
    main()

错误的文件描述符套接字和线程
