The issue with ngFileUpload causing empty file posts on Safari

Currently, I am utilizing ngFileUpload to transmit images to the Cloudinary service. My application is constructed on Ionic and is meant to be functional on both iOS and Android platforms. The code snippet below showcases my image uploading process:

.service('photoUploadService', ['$q','Upload', '$ionicLoading', 'AppModel',
function($q, $upload, $ionicLoading, AppModel){
    // implementation details omitted for brevity
}]);

Under the Android environment, the code runs smoothly and uploads the images successfully. However, when executed on iOS, an "Empty File" error message is received from Cloudinary. After thorough debugging, it appears that the file creation process is correct, with the only error being reported as "Empty file".

Thus far, I have attempted the solutions provided in several posts such as Convert base64 data url to image file in angularjs, Convert base64 data image file in angularjs, and . Unfortunately, none of these attempts have resolved the issue.

If anyone has insights or suggestions pertaining to this matter, your assistance would be greatly valued.

Answer №1

For those facing a similar issue, it seems that ng-file-upload is not compatible with cordova. You can refer to the original answer ng-file-upload not uploading in Ionics

If you need code to easily upload images to cloudinary, here is what worked for me.

ref.uploadPhoto = function(imageData, album, waitMessage, imgType){
    var deferred = $q.defer();
    var filename = Math.floor(Math.random()*90000) + 10000 + ".png";
    var options = {
        fileName: filename,
        chunkedMode: false,
        mimeType: "image/png",
        params: {'upload_preset': "XXXXX",
                'tags': album,
                'context': 'photo=' + filename},

    };

    $cordovaFileTransfer.upload("https://api.cloudinary.com/v1_1/XXXXX/upload",
        imageData, options)
        .then(function(result){
            var response = JSON.parse(result.response);
            response.type = imgType;
            deferred.resolve(response);
        }, function(err){
            console.error(err);
            deferred.reject(err);
        }, function(progress){
            var val = Math.round(((progress.loaded * 100.0) / progress.total));
            console.log(val);
            if(waitMessage){
                $ionicLoading.show({template: waitMessage + val + "%"});    
            }
        }).catch(function(err){
            console.error(err);
            deferred.reject(err);  
        });

    return deferred.promise;
};
