Question

将单个图片上传到我的api时遇到一个小问题。 api端点完成后只需要一张图片。

我在项目中使用cordova相机插件拍照。它返回bas64。我找到了一种方法，将其转换为jpg，代码如下

 $scope.picture = 'data:image/jpeg;base64,' + data;
            var blob = new Blob([$scope.picture], {type: 'image/png'});
            var picture = new File([blob], 'picture.jpg');

在我转换它之后（我假设有效）我从角度使用以下代码获得正常的http指令。

$http({
     method: 'POST',
     url: '/me/saveavatar',
     headers: {
         'Content-Type': undefined
         },
     data: {
         photo: picture
       }
     })
    .success(function (data) {
        console.log("success" + data);
     })
    .error(function (response) {
         console.log("error" + response);
    });

但我没有将我的文件上传到服务器。如果它是第一个文件。我错过了什么？

完整的功能如下：

$scope.takePicture = function(){
        var options = {
            //these are option that are passed to the function so we can grab the picture and zise it the way we want.
            destinationType: Camera.DestinationType.DATA_URL,
            encodingType: Camera.EncodingType.JPEG,
            targetWidth: 250,
            targetHeight: 500,
            allowEdit : true,
            quality:100

        };
       //the plugin is calling upon the camera the plugin is called cordovaCamera
        $cordovaCamera.getPicture(options).then(function(data) {
         //succes handeling
           $scope.picture = 'data:image/jpeg;base64,' + data;
            var blob = new Blob([$scope.picture], {type: 'image/png'});
            var picture = new File([blob], 'picture.jpg');
            //uploading the picture
                console.log(picture);
                $http({
                    method: 'POST',
                    url: '/me/saveavatar',
                    headers: {
                        'Content-Type': undefined
                    },
                    data: {
                        photo: picture
                    }
                })
                    .success(function (response) {
                        console.log("success" + response);
                    })
                    .error(function (response) {
                        console.log("error" + response);
                    });
        },
        // Error handeling
        function(){
            var alertPopup = $ionicPopup.alert({
                title: 'Camera afgesloten?',
                template: 'U kunt altijd nog een foto maken!'
            });
        });
    };
