        self.strResult = "ok"

在com.zxy.main.Init_Page.py中添加代码

from com.zxy.tcp.ServerThread import ServerThread

    @staticmethod
    def Start_Server():
        st = ServerThread("", "", int(Com_Para.AccSocketPort))
        # TCP服务端案例
        t2 = threading.Thread(target=st.run, name="ServerMainThread")
        t2.start()

TCP Server测试案例MonitorDataCmd.py主文件中编写：

在    if __name__ == '__main__':下添加

        #TCP Server接收数据拦截器插件
        Com_Para.ServerREFLECT_IN_CLASS = "com.plugins.usereflect.testServerReflectInClass1"
        #TCP Server配置端口参数 
        Com_Para.AccSocketPort = "8099"
        #TCP/IP Server初始化
        Init_Page.Start_Server()
        #暂停120秒,等待client连接
        time.sleep(120)
        #遍历已经连接到本设备的tcp client并发送数据包
        for key in Com_Para.dServThreadList.keys():
            temSck = Com_Fun.GetHashTableNone(Com_Para.dServThreadList, key)
            temValue = "Server往Client端发送数据包:"+Com_Fun.GetTimeDef()
            Com_Fun.SendSocket(temValue, temSck)
            print("=>"+key+"=>"+temValue)
