我想在其他文件中使用var值,如果我在我的代码的开始定义它会引发错误“无法读取null属性'统计'”,所以我尝试使用全局变量但这没有帮助,在我的其他文件中总是得到空值。值得到未定义控制器nodejs
我需要在其他文件中获取listaLive,listaRepeated和listaPasserBy值,我将这些数据发送给它们,然后插入到db(AgregateController)中。
当时我的代码是:
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) {
console.log("probing 2--> ",e);
createLog('error', __dirname, __filename.slice(__dirname.length + 1, -3), null, 'probing','getDevices',e);
});
}

我需要的资源列表的这个值上agregator ...
你在哪里试图在不同的文件中使用变量?哪条线给你这个错误?如果这是Node.js,则不要使用全局变量。使用模块。 –
我正在使用注释行//obj["data"].stats=statsData["stats“]来使用这些数据,它会引发给定的错误,但是如果填充了错误,则会出现错误再次出现了解......当仍然存在时空引发错误...我需要这个数据在AgregateController明白..但在这个文件中传递的数据是空的... – ricardol
