Google Cloud Storage file upload fails on ios device

[torayeff]

Uploading to Google Cloud Storage from iOS device gives this error:

Error: Failed to upload file to cloud storage [ - 0]
{"error":" - 0","reason":"Failed to upload file to cloud storage","message":"Failed to upload file to cloud storage [ - 0]","errorType":"Meteor.Error"}

It works, on android simulator, ios simulator and android device but not in ios device. This is my code:

'click [data-action=browse-gallery]': function() {
        var options = {  
            width: 256,
            height: 256,
            quality: 75,
            sourceType: Camera.PictureSourceType.PHOTOLIBRARY
        };

        MeteoricCamera.getPicture(options, function(err, dataURI){
            if (err) {
                alert(err);
            } else {
                $('.avatar-actions').hide();
                $('.avatar-options').show();
                Session.set('test-img', dataURI);
            }
        });
    },

    'click [data-action=upload-avatar]': function() {
        var avatarUploader = new Slingshot.Upload('avatarUploader');
        var img = dataURItoBlob(Session.get('test-img'));

        $("#upload-btn").hide();
        $(".loading").show();

        avatarUploader.send(img, function(err, url) {
            if (err) {
                console.log(err);
                alert(err);
            } else {
                Meteor.call('changeAvatar', url);
                Router.go('account');
            }
        });
    },

While I cannot test things on iOS, I can only suggest that you try Slingshot.GoogleCloudResumable that you can find on this branch.

It is an old branch, which was never released because there is a bug in google-cloud CORS mechanism, meaning that it will not work in a browser. But do I imagine that this would not be a problem in cordova.

@gsuess Yes it was definitely CORS problem, this CORS.json works for me:

[
  {
    "origin": ["*"],
    "responseHeader": ["*"], //note here
    "method": ["GET", "POST", "PUT", "HEAD"],
    "maxAgeSeconds": 3000
  }
]
