Question

我正在尝试开发服务器-客户端类型的应用程序。我想从服务器向客户端发送一条消息（如下所示）。并非所有客户端都直接与服务器（多跳）通信连接。我想在客户端（接收方）收到消息时在发送方（服务器）得到确认。如果假设服务器未收到确认，则服务器将再次向该客户端重新发送相同的消息。在我的代码中，我尝试将与ack相同的消息发送回（从cleint到服务器）。服务，但我的错误点中断了。

任何机构都可以帮助解决此错误吗？我如何发送确认。邮件从接收人（接收者）发送到服务器（发件人）

预先感谢

发送方

    MyNeighborSet_ip= ['192.168.1.2']    
    Data_transfer_listt = [['192.168.1.1', '192.168.1.2'], ['192.168.1.2', '192.168.1.3'], ['192.168.1.2', '192.168.1.4'], ['192.168.1.4', '192.168.1.5'], ['192.168.1.4', '192.168.1.6']]    
    received_list=[]
    def sending_Neighobr_ip_list():
        message='Neighbor_list_sending'
        PORT = 12345

    for k in range (len(MyNeighborSet_ip)):
        s=socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        s.connect((MyNeighborSet_ip[k],PORT))

            s.sendall (T_message_bytes)

        s.close()

        if not message_chunk:
            break
        received_list.append(message_chunk)    
    conn.close()
    print ("after the recv_message_list",received_list)
    return 


temp= concurrent.futures.ThreadPoolExecutor (max_workers=2)
temp.submit(sending_Neighobr_ip_list)

接收器端

data =[]
ip_list=[]
def frame_reception_function ():

    PORT = 12345
    s=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
    s.setsockopt(socket.SOL_SOCKET,socket.SO_REUSEADDR,1)
    s.bind(('',PORT))
    s.listen(1)
    conn,address=s.accept()  
    while True:
        datachunk=conn.recv(1024).decode()  
        #print (conn)
        print (datachunk)
        if not datachunk:
            break  
        data.append(datachunk)  
        ip_list.append(address[0])
        T_message_bytes= bytes(datachunk,'utf-8')
        s.sendall(T_message_bytes)
    conn.close()
    return


if __name__ == '__main__':
  p1 = Process(target=frame_reception_function)
  p1.start()
  p1.join()
