Sync-Code für Promise Alle

Question

Hallo allerseits Ich habe Probleme mit meinem Code, weil Versprechen auf eine asynchrone Art und Weise gemacht werden, und ich brauche sie zu synchronisieren. Also habe ich diese Funktion den Wert der beiden Versprechen zurückzukehren innen fullfilled

ServicesController.prototype.uci = function (device, config, path, section, property, value, apply, commit) { 
    createLog('debug', __dirname, __filename.slice(__dirname.length + 1, -3), device.id, 'uci', 'inicio'); 

    createLog('debug', __dirname, __filename.slice(__dirname.length + 1, -3), device.id, 'uci', 'config', config); 
    createLog('debug', __dirname, __filename.slice(__dirname.length + 1, -3), device.id, 'uci', 'path', path); 
    createLog('debug', __dirname, __filename.slice(__dirname.length + 1, -3), device.id, 'uci', 'section', section); 
    createLog('debug', __dirname, __filename.slice(__dirname.length + 1, -3), device.id, 'uci', 'option', property); 
    createLog('debug', __dirname, __filename.slice(__dirname.length + 1, -3), device.id, 'uci', 'value', value); 
    createLog('debug', __dirname, __filename.slice(__dirname.length + 1, -3), device.id, 'uci', 'apply', apply); 
    createLog('debug', __dirname, __filename.slice(__dirname.length + 1, -3), device.id, 'uci', 'commit', commit); 

    var values = {}; 
    values[property] = value; 
    createLog('debug', __dirname, __filename.slice(__dirname.length + 1, -3), device.id, 'uci', 'values', values); 

    return Controllers.Ubus.uciRequest('set', {"config": config, "section": section, values}, device) 
      .then(function (uciData) { 
       createLog('debug', __dirname, __filename.slice(__dirname.length + 1, -3), device.id, 'uci', 'uciData', uciData); 
       var promises = []; 

       if (uciData != null) { 
        createLog('info', __dirname, __filename.slice(__dirname.length + 1, -3), device.id, 'uci', 'depois do if do uciData'); 

        if (commit) { 
         createLog('debug', __dirname, __filename.slice(__dirname.length + 1, -3), null, 'uci', 'commit'); 
         var p1 = new Promise(function (resolve, reject) { 
          Controllers.Ubus.uciRequest('commit', {"config": config}, device) 
           .then(function (dataCommit) { 
            if (dataCommit && dataCommit.hasOwnProperty('result') && dataCommit.result[0] == 0) { 
             createLog('info', __dirname, __filename.slice(__dirname.length + 1, -3), null, 'uci', 'commit data', dataCommit); 
             resolve(dataCommit.result[0]); 
            } else { 
             reject("no data"); 
            } 
           }).catch(function (err) { 
            createLog('error', __dirname, __filename.slice(__dirname.length + 1, -3), null, 'uci', 'error promise commit', err); 
           }); 
         });       
         promises.push(p1); 
        } 

        if (apply) { 
         createLog('debug', __dirname, __filename.slice(__dirname.length + 1, -3), null, 'uci', 'apply'); 
         var p2 = new Promise(function (resolve, reject) { 
           Controllers.Ubus.fileExec(device.id, "exec", path, "restart") 
           .then(function (dataApply) { 
            if (dataApply && dataApply.hasOwnProperty('result') && dataApply.result[0] == 0) { 
             createLog('info', __dirname, __filename.slice(__dirname.length + 1, -3), null, 'uci', 'apply data', dataApply); 
             resolve(dataApply.result[0]); 
            } else { 
             reject("no data"); 
            } 
           }).catch(function (err) { 
            createLog('error', __dirname, __filename.slice(__dirname.length + 1, -3), null, 'uci', 'error promise apply', err); 
           }); 
         });       
         promises.push(p2); 
        } 
        createLog('debug', __dirname, __filename.slice(__dirname.length + 1, -3), null, 'uci', 'promises ', promises); 
       } 
      }).then(function (promises) { 
       createLog('debug', __dirname, __filename.slice(__dirname.length + 1, -3), null, 'uci', 'promises then', promises); 
       Promise.all(promises).then(function (values) { 
        createLog('debug', __dirname, __filename.slice(__dirname.length + 1, -3), null, 'uci', 'promises all', values); 
return(values); 

       }).catch(function (err) { 
        createLog('error', __dirname, __filename.slice(__dirname.length + 1, -3), null, 'uci', 'error promise all', err); 
       }); 
      }).catch(function (err) { 
       createLog('error', __dirname, __filename.slice(__dirname.length + 1, -3), null, 'uci', 'error then 2', err); 
      }); 
} 

Durch meine Protokolle Ich Eingabe die in Anwendung und begehen, wenn.

Im Moment bin ich Empfang dieses Protokoll:

[2017-06-08 15:37:39.621] - error: /opt/wscontroller/wscontroller-api/routes/services ServicesController NA uci error promise all {} 

Wer kann mir etwas Hilfe dieses Problem zu lösen?

Answer 1

Das Problem ist keine Promise oder ein anderer Wert ist eigentlich return Ed von verkettet zu Controllers.Ubus.uciRequest() Anrufe.

Answer 2

Sie müssen das Versprechen Array in der ersten Rück dann
