Access a file in business Logic

Hey,


i want to build some logic regarding files inside my business logic - how can i find an file.object inside bl ?



modules.collectionAccess.collection('files').find({'_id' : doc.avatar._id}, {}, function(err, file){
...


Doesn't seem to work. What's wrong?


Hi,


Files aren't stored directly with Kinvey (they're on Google Cloud Storage). That's why accessing them is a little different compared to the data in collections.

Hey,


thanks for your reply - strange that it isn't available like a find or insert?

Hi Nico,


Apologies for the late reply.


Please refer to the code below   

  var context = modules.backendContext;
  var utils = modules.utils;
  var appKey = context.getAppKey();
  var masterSecret = context.getMasterSecret();
  var uri = 'https://' + request.headers.host + '/blob/'+ appKey + '/' + doc.avatar._id; // id variable
  var authString = "Basic " + utils.base64.encode(appKey + ":" + masterSecret);
  var requestOptions = {
    uri:uri, 
    headers: {
      "Authorization":authString
    }
  };
  var auth = modules.request.get(requestOptions,function(error, res, body){
    if (error){
      response.error(error);
    } else {
      response.body = JSON.parse(body);
      response.complete(res.status);
    }
  });

  

I have tested this in BL. This should work with your doc.avatar._id value.


I am checking if there is a simpler way to do this. I will get back to you on that.

Anyone on this? Can't be a big deal ?!


Best, Nico
