通过角度http请求发布文件

Question

I'm using angularjs and I'm trying to upload a picture to a django backend server along with other data in the request body.

I keep getting an error from the server telling me that the picture I sent was not a file. (Assume that the backend has no problems)

I've tried using ng-file-upload ( https://github.com/danialfarid/ng-file-upload ) to get the file and then send it through angular itself. (Note: I need to send other data along with the picture) so I want to store the file in a variable and pass it in the request body like so:

<form name="form">
<div class="button" ngf-select ng-model="file" name="file" ngf-resize="{width: 100, height: 100}">Select</div>
<button type="submit" ng-click="submit()">submit</button>
</form>

since the file is stored in $scope.file, I try to use it in the http request:

$http({
          'method': "PUT",
          'url': "api/candidate-profiles/" + id,
          'data':data
})

where data is:

{"id": $scope.id,
"name": $scope.name,
"avatar":$scope.file}

I get a validation error from the backend specifiying that the avatar is not a file. Any help?

                        })
            }else{

                  alert('Form is not valid');
            }

I think you should read the documentation, and see some samples like this

app.controller('MyCtrl', ['$scope', 'Upload', '$timeout', function ($scope, Upload, $timeout) {
    $scope.uploadPic = function(file) {
    file.upload = Upload.upload({
        url: 'https://angular-file-upload-cors-srv.appspot.com/upload',
        data: {username: $scope.username, file: file},
    });

    file.upload.then(function (response) {
        $timeout(function () {
            file.result = response.data;
        });
    }, function (response) {
        if (response.status > 0)
          $scope.errorMsg = response.status + ': ' + response.data;
    }, function (evt) {
        // Math.min is to fix IE which reports 200% sometimes
        file.progress = Math.min(100, parseInt(100.0 * evt.loaded / evt.total));
    });
    }
}]);
