Wert wird undefiniert zwischen Controllern nodejs

Question

Ich versuche, einen var -Wert in einer anderen Datei zu verwenden, und wenn ich es am Anfang meines Codes definiere, löst es den Fehler aus "Kann Eigenschaft 'stats' von null nicht lesen" so versuche ich benutze globals aber das hilft nicht, bekomme immer null in meiner anderen Datei.

Ich brauche listaLive, listaRepeated und listaPasserBy Werte in anderen Datei, wo ich diese Daten senden, um sie zu verarbeiten und dann in db (AgregateController) einfügen.

Zu der Zeit ist mein Code:

ProbingController.prototype.pollingAllDevices = function() { 
    createLog('info', __dirname, __filename.slice(__dirname.length + 1, -3), null, 'probing', 'inicio'); 
    var numDevices = 1; 
    return Database.Devices.getDevices().then(function (devices) { 
     return new Promise(function (resolve, reject) { 
      async.each(devices, function (device, callback) { 
       logger.info('WSController-Service', 'probing', 'getRadioInfo --> ', device.id, ' :: ', numDevices++, '/', devices.length); 
       //stats ubus call wsniffer stats pie chart 
       //list ubus call wsniffer list 
       //listex ubus call wsniffer listex 

        var obj = { 
         "id": uuid.v4(), 
         // "timestamp": new Date().getTime(), 
         "device_id": device.id, 
         "data":{ 
          "stats":{ 
          }, 
          "list":{ 
          } 
         } 
        }; 

        var allPromises=[];     

        allPromises.push(Controllers.Gps.getRadioInfo('wsniffer', 'stats', {}, device)); 
        allPromises.push(Controllers.Gps.getRadioInfo('wsniffer', 'list', {}, device)); 

        Promise.all(allPromises).then(function(values){ 
         console.log("probing values -> "+device.id+" "+ JSON.stringify(values));  
         for(var j=0;j<values.length;j++){ 
          if(values[j]!=null){ 
           console.log("stats "+device.id+" --> "+ values[0]["stats"]); 
           console.log("list "+device.id+" --> "+ values[1]["list"]); 
           if(values.stats["stats"]!=undefined){ 
            obj.data.stats = values[0]["stats"]; 
           } 
           if(values.stats["list"]!=undefined){ 
            obj.data.list = values[1]["list"]; 
           }        
          } 
         } 
         var countRepetidos=0; 
         if(obj["list"]!=undefined && obj["list"].length>0){      

          var aux = obj["list"]; 
          for(var j=1;j<aux.length;j++){ 
           var tmp = aux; 
           for(var k=1;k<tmp.length;k++){ 
            if(j!=k){ 
             if(aux[j] === tmp[k]){ 
              countRepetidos++; 
              aux.splice(k,1); 
             } 
            } 
           } 
          } 
         } 

         var dataLive = []; 
         var dataRepeated= []; 
         var dataPasserBy = []; 

         var now = Date.now(); 

         var listaLive=[], listaRepeated=[], listaPasserBy=[]; 

         if(obj.data.stats!=undefined){ 
          dataLive = [obj.data.stats.since, obj.data.stats.live]; 
          dataPasserBy = [obj.data.stats.since, obj.data.stats.passerby]; 
         } 

         dataRepeated = [obj.data.stats.since, countRepetidos]; 


         createLog('debug', __dirname, __filename.slice(__dirname.length + 1, -3), device.id, 'probing', 'obj', obj); 

         listaLive.push(dataLive); 
         listaRepeated.push(dataRepeated); 
         listaPasserBy.push(dataPasserBy); 

         Controllers.Agregate.agregateData("probing_live", 5 * 60, listaLive, dbHistConnectionString, device.id, device.network_id, device.organization_id, ["time","clients"]); 
         Controllers.Agregate.agregateData("probing_repeated", 5 * 60, listaRepeated, dbHistConnectionString, device.id, device.network_id, device.organization_id, ["time","clients"]); 
         Controllers.Agregate.agregateData("probing_passerBy", 5 * 60, listaPasserBy, dbHistConnectionString, device.id, device.network_id, device.organization_id, ["time","clients"]); 
         Database.Probing.addRow(obj); 

         global.listaLive = listaLive; 
         global.listaRepeated = listaRepeated 
         global.listaPasserBy = listaPasserBy 


        }).catch(function (e) { // error handling 
         console.log("probing - promiseall ",device.id,e); 
         if(values==null){ 
          console.log('probing values null ---->', device.id); 
         } 
         createLog('error', __dirname, __filename.slice(__dirname.length + 1, -3), device.id, 'probing', 'no promise all',e); 
         return callback(e); 
        }); 


      }, function (error) { 
       if (error) { 
        createLog('error', __dirname, __filename.slice(__dirname.length + 1, -3), null, 'probing', 'stops polling?!', error); 
        return reject(error); 
       } 
       createLog('info', __dirname, __filename.slice(__dirname.length + 1, -3), null, 'probing','All Devices Processed'); 
       return resolve(); 
      }); 
     }).catch(function (e) { 
      console.log("probing 1--> ",e); 
      createLog('error', __dirname, __filename.slice(__dirname.length + 1, -3), null, 'probing','promise',e); 
     }); 
    }).catch(function (e) {

     createLog('error', __dirname, __filename.slice(__dirname.length + 1, -3), null, 'probing','getDevices',e);

}

Wo "Zeitstempel" und "Summe" sind die Werte auf der Agregate innerhalb von listaLive, listaRepeated und listaPasserBy.

3|wscontro | probing timestamp [ undefined, 0 ] 
3|wscontro | probing sum undefined 

Ich brauche diese Werte von der Liste auf Agregator ...

Answer 1

Sie einen beliebigen Wert teilen können Sie das exports-Objekt werden soll.

Versuchen Sie also, Ihre var-Variable mithilfe von Exporten zu exportieren. Beispiel:

**helper.js** 

const hello = 'hello world' 
exports.hello = hello 

**index.js** 

const example = require('./helper.js').hello 
console.log(example) //Will show 'hello world'
