1. 监测数据采集物联网应用开发步骤(8.2)

TCP/IP Server开发

在com.zxy.common.Com_Para.py中添加如下内容

#锁机制
lock = threading.Lock()
#本机服务端端口已被连接客户端socket list
dServThreadList = {}
#作为服务端接收数据拦截器
ServerREFLECT_IN_CLASS = "com.plugins.usereflect.testServerReflectInClass1"
#本设备Server端口
AccSocketPort = 8090

在com.zxy.business.Analyse_Data.py类的

def SubAnalyseRecBytes函数中添加如下内容

        #作为服务端接收数据拦截器
        elif inputIServ and Com_Para.ServerREFLECT_IN_CLASS != "":
            try:
                objC = importlib.import_module(Com_Para.ServerREFLECT_IN_CLASS)  #对模块进行导入                
                objName = Com_Para.ServerREFLECT_IN_CLASS.split(".")
                objN = getattr(objC,objName[len(objName) - 1])
                if hasattr(objN,"strResult"):
                    setattr(objN,"strResult",inputStrResult)
                    setattr(objN,"strIP",inputStrIP)
                    setattr(objN,"strPort",inputStrPort)
                    fun_us = getattr(objN,"init_start")
                    fun_us(objN)
                    temResult = getattr(objN,"strResult")
                    temSend = getattr(objN,"strSend")
                    temContinue = getattr(objN,"strContinue")
                    #发送到客户端数据
                    if temSend != "":
                        Com_Fun.SendSocket(temSend,inputMServSocket)
                    #不继续执行操作
                    if temContinue == "0":
                        return ""
            except Exception as e:
                if str(type(self)) == "<class 'type'>":
                    self.debug_in(self,Com_Para.ServerREFLECT_IN_CLASS+"=1=>"+repr(e)+"=>"+str(e.__traceback__.tb_lineno))#打印异常信息
                else:
                    self.debug_in(Com_Para.ServerREFLECT_IN_CLASS+"=1=>"+repr(e)+"=>"+str(e.__traceback__.tb_lineno))#打印异常信息
            finally:
                pass 

在com.zxy.common.Com_Fun.py中添加代码

    @staticmethod
    def SetThreadList(inputStrkey, inputStrValue):
        if Com_Para.dServThreadList is None:
            Com_Para.dServThreadList = {}
        if Com_Para.lock.acquire():
            Com_Para.dServThreadList[inputStrkey] = inputStrValue
            Com_Para.lock.release()
            
    @staticmethod        
    def RemoveThreadList(inputStrkey):
        if Com_Para.lock.acquire():
            if Com_Para.dServThreadList.get(inputStrkey) is not None:
                Com_Para.dServThreadList.pop(inputStrkey)
            Com_Para.lock.release()
