Sails.js - 컨트롤러 문제

Question

일부 데이터를 검색하기 위해 다음 코드 (SoundCloudController.js)를 사용하여 SoundCloud API에서 JSON을 구문 분석 할 컨트롤러를 개발 중입니다. 응용 프로그램을 들어서 내가 만든보기로 이동하십시오. "result.ejs", 충돌합니다.

module.exports = { 

    // Search for something 
    // SoundCloud API reference: 
    // https://developers.soundcloud.com/docs/api/reference#tracks 
    result: function (req, res, next) { 
     SoundCloud.find(function foundSounds(err, sounds) { 
      if (err) return next(err); 

      var http = require('http'); 

      function process_response(webservice_response, sound, callback) { 
       var webservice_data = ""; 
       webservice_response.on('error', function (e) { 
        console.log(e.message); 
        callback("Error: " + e.message); 
       }); 
       webservice_response.on('data', function (chunk) { 
        webservice_data += chunk; 
       }); 

       // Response from query 
       webservice_response.on('end', function() { 
        // Parse everything from the response (JSON) 
        sound_data = JSON.parse(webservice_data); 
        // Find the title of the first match 
        sound.title = sound_data.title; 
        // The duration provided by SoundCloud is in milliseconds 
        // convert to MM:SS format for readability 
        sound.duration = millis_to_min_sec(sound_data.duration); 
        // Logo for SoundCloud 
        sound.logo = 'http://icons.iconarchive.com/icons/sicons/basic-round-social/512/soundcloud-icon.png'; 
        console.log(sound.title + ' ' + sound.duration); 
        callback(); 
       }); 
      }; 

      // Define host, path etc. for the search (JSON returned) 
      function get_sound_data(sound, callback) { 
       //http://api.soundcloud.com/tracks.json?client_id=CLIENT_ID_HERE&q=smile%20like%20you%20mean%20it 
       console.log(sound.title); 
       console.log(sound.duration); 
       options = { 
        host: 'http://api.soundcloud.com', 
        port: 80, 
        path: '/tracks.json?client_id=O3UkayfZTJjNeahVhqTiHcZ5iowrMRpk&q=smile like you mean it&limit=2', // client_id is given above, q='something to search for', limit to 2 results 
        method: 'GET' 
       }; 

       var webservice_request = http.request(options, function (response) { 
        process_response(response, sound, callback) 
       }); 
       webservice_request.end(); 

      }; 

      // Convert milliseconds to MM:SS format (minutes:seconds) 
      function millis_to_min_sec(millis) { 
       var minutes = Math.floor(millis/60000); 
       var seconds = ((millis % 60000)/1000).toFixed(0); 
       return minutes + ':' + (seconds < 10 ? '0' : '') + seconds; 
      }; 

      async.each(sound.sounds, get_sound_data, function(err) { 
       if(err) console.log(err); 
       console.log('done'); 

       res.view({ 
        sound: sound 
       }); 
      }); 
     }); 
    }, 

};

어떤 개선을위한 제안 및/또는 내 문제를 해결하기 위해 솔루션 크게 감사합니다!

으로 갈 때 music 모델에 대한 청사진 경로를 실수로 들르는 것처럼 보입니다. URL 형식이 /:model/:id 인 ID는 result입니다. 경로 구성이 해당 형식을 무시하도록 설정되어 있고 SoundCloudController.result을 가리키고 있는지 확인하십시오.
