寻找一种使用Ajax使用angularjs将文件上传到Appengine Go服务器的方法

Javascript code:

$http({
    method: 'POST',
    url: 'some/path',
    headers: { 'Content-Type': false },
    transformRequest: function (data) {
      var formData = new FormData();
      formData.append("file", data);
      return formData;
    },
    data: file
}).
success(function (data, status, headers, config) {
    alert("success!");
}).
error(function (data, status, headers, config) {
    alert("failed!");
});

Server code:

func addImageHandler(w http.ResponseWriter, r *http.Request) {
    c := appengine.NewContext(r)
    blobs, _, err := blobstore.ParseUpload(r)
    if err != nil {
        http.Error(w, err.Error(), http.StatusInternalServerError)
        return
    }

    file := blobs["file"]
    ....
}

I'm hitting the handler just fine but when i parse the upload I don't have any files in my blobs map. Is there something obvious i'm missing?

Thanks!

    The problem has turned out to be a detail that wasn't included in the original question. You need to ensure that you're using the blobstore to generate the upload url. For example:

    func ServeUploadUrl(w http.ResponseWriter, request *http.Request) {
        context := appengine.NewContext(request)
        myUrl := "some/upload/url"
    
        // create the blobstore url here
        blobstore.UploadURL(context, myUrl, nil)
        ...
    }
