python - 为什么我不能接受客户？

Question

我启动了一个连接到客户端的简单服务器，一个月前它可以工作，但现在不行了。

主要

def main():
    (client_socket, client_address) = start_server(('0.0.0.0', 8200))

    print("online")
    menu = """
        enter the mode wanted out of:
        write,
        random,
        cal,
        file,
        close to terminate connection"""
    menu = menu.encode()
    main_menu(client_socket, menu)
    client_socket.close()
    server_socket.close()


if __name__ == '__main__':
    main()

启动服务器功能

def start_server(addr):
    global server_socket
    server_socket = socket.socket()
    server_socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
    server_socket.bind(addr)
    server_socket.listen(1)
    (client_socket, client_address) = server_socket.accept()
    return client_socket, client_address

服务器不运行 server_socket.accept()我为客户收到此错误:

OSError: [WinError 10049] The requested address is not valid in its context

客户端套接字

    my_socket = socket.socket()  # creates the socket
    my_socket.connect(('0.0.0.0', 8200))  # connects to the server
    choose_mode(my_socket)  # main menu

为什么它不接受客户？

Answer 1

我绑定(bind)了 0.0.0.0 和 8200，但连接到了 127.0.0.1。
服务器 (client_socket, client_address) = start_server(('0.0.0.0', 8200)) 客户my_socket.connect(('127.0.0.1', 8200)) # connects to the server
正如我所解释的:
因为 0.0.0.0 不是要连接的目标地址，并且绑定(bind)到 127.0.0.1 通常过于严格
