随机发送TCP消息给python中的几个客户端之一

标签: python python-multithreading tcp-ip

我试图在随机时间发送TCP消息,具体取决于收到用户输入的时间,发送给我从中接收每个客户端线程数据的多个客户端之一。

我将每个客户端的IP存储在SQL数据库中,我决定根据用户输入发送数据的IP。我该如何处理向特定客户发送消息?我不知道如何通过每个套接字连接访问并使用它来发送消息。

非常欢迎任何设备,示例链接或代码段。

这是我到目前为止的服务器代码:

import socket
import threading
from database import Database

d = Database()
def Read_RFID_tag():
    while True:
        receiveID = raw_input("tag input : ")
        d.updateTable(receiveID, 1);
        print(receiveID)

class ThreadedServer(object):
    def __init__(self, host, port):
        self.host = host
        self.port = port
        self.sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        self.sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
        self.sock.bind((self.host, self.port))

    def listen(self):
        self.sock.listen(5)
        while True:
            client, address = self.sock.accept()
            print("new client")
            client.settimeout(60)
            threading.Thread(target = self.listenToClient,args = (client,address)).start()

    def listenToClient(self, client, address):
        size = 1024
        while True:
            query_result = d.existsWashedInTable(address)
            try:
                data = client.recv(size)
                if data:
                    # Set the response to echo back the received data
                    print(data)
                    response = data
                    d.addEntryToTable(response,address, 0)
                    client.send(response)
                else:
                    raise error('Client disconnected')
            except:
                client.close()
                return False

if __name__ == "__main__":
    port_num = 5005
    d.createTable()
    threading.Thread(target=Read_RFID_tag).start()
    ThreadedServer('',port_num).listen()
