Question

我正在尝试使用纯粹的javascript将图片上传到Google Blobstore。我有一个REST api，我查询以获取上传URL。我抓住上传网址并使用以下代码发布：

<form id="newmemberAccount" class="form-horizontal" enctype="multipart/form-data" role="form">

<div class="form-group">
    <label for="fileUpload" class="col-sm-2 control-label">Upload Picture</label>
    <div class="col-sm-10">
      <input type="file" name="file" onchange="angular.element(this).scope().uploadFile(this.files)"/>
    </div>
</div>

<button type="submit" ng-click="uploadPicture()" class="btn btn-default pull-right">Submit</button>

然后我通过Angular控制器中的以下代码获取信息：

$scope.uploadFile = function(files) {
        newprofileImage = new FormData();
        //Take the first selected file
        newprofileImage.append("file", files[0]);
    }


$scope.uploadPicture = function(){

        console.log(newprofileImage);
        $http.post($scope.url, newprofileImage, {
            headers: {'Content-Type': undefined},
            transformRequest: angular.identity,
            })
        .success(function(data){
            console.log("success");
            console.log(data);
        })
        .error(function(data) {
            console.log("failure");
            console.log(data);
        });
    }

当我运行post请求时，我收到了404响应，但我可以看到图像已上传到app引擎控制台中的blob。所以我真的很困惑我做错了什么。我需要获得响应，以便我可以找到托管图像的位置。下面我将发布从Chrome控制台获取的http请求发送的内容。请求标题：
