Sending more than just an image to blobstore's upload url from Android?

Question

I've recently been experimenting with uploading images to blobstore. I have the whole process working already and am able to successfully upload images to blobstore. My question is if I can send more than just an image to the upload url? The engine saves my image and then redirects the user to my upload handler. However, I am not sure how to send information (such as user id) to the upload url so that it is then sent to my upload handler. Any help would be appreciated.

Thank you!

您可以通过添加请求参数或额外的路径信息，使用所需的信息（例如用户ID-假设您在生成上传URL时就知道它）来构造回调（successPath）。
