Socket recv in Python 3 一遍又一遍地重复输入

Question

我知道它发送这么多的原因是我将 recv 设置为 1024 并且可以通过更改它来更改允许的数量，但是我只希望发送一个 Hello World。我试着搜索这个问题，但没有找到真正有用的东西。提前致谢！！

服务器：

#!/usr/bin/python
import socket
import sys


class Server:
    def __init__(self, sock=None):
        if sock is None:
            self.sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
            print("socket created")

    def bind(self, HOST, PORT):
        try:
            self.sock.bind((HOST, PORT))
        except socket.error as msg:
            print("Bind failed. Error Code : " +
                    str(msg[0]) + "Message " + msg[1])
            sys.exit()
        print("Socket bind complete")

    def main_loop(self):
        self.sock.listen(10)
        print("Socket now listening")
        while 1:
            conn, addr = self.sock.accept()
            print("Connected with " + addr[0] + ":" + str(addr[1]))
            data = conn.recv(1024)
            print(data)
        self.sock.close()

    def main(self):
        HOST = ''
        PORT = 8888
        self.bind(HOST, PORT)
        self.main_loop()


def main():
    server = Server()
    server.main()


if __name__ == "__main__":
    main()

客户

#!/usr/bin/python
import socket
import sys


class Client:
    def __init__(self, sock=None):
        if sock is None:
            self.sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
            print("socket created")

    def connect(self, HOST, PORT):
        try:
            self.sock.connect((HOST, PORT))
        except socket.error as msg:
            print("Connect failed. Error Code : " +
                    str(msg[0]) + "Message " + msg[1])
            sys.exit()
        print("Socket connect complete")

    def main_loop(self):
        while 1:
            self.sock.sendall(b'Hello world')
        self.sock.close()

    def main(self):
        HOST = ''
        PORT = 8888
       self.connect(HOST, PORT)
       self.main_loop()


def main():
    client = Client()
    client.main()


if __name__ == "__main__":
    main()

服务器输出：

socket created
Socket bind complete
Socket now listening
Connected with 127.0.0.1:45676
b'Hello worldHello worldHello worldHello worldHello worldHello worldHello worldHello worldHello worldHello worldHello worldHello worldHello worldHello worldHello worldHello worldHello worldHello worldHello worldHello worldHello worldHello world'

客户端输出：

socket created
Socket connect complete

Answer 1

我怀疑问题出在客户端，而不是服务器：

def main_loop(self):
    while 1:
        self.sock.sendall(b'Hello world')
    self.sock.close()

当调用main_loop方法时，它会发送'Hello world'直到用户干预或进程死亡或计算机楔入或宇宙热寂，以先发生者为准。
