如何在BlobstoreUploadHandler（appengine）中获取唯一的上传URL

Question

from google.appengine.ext import blobstore
upload_url = blobstore.create_upload_url('/upload')

uplaod_url是一个独特的网址，如何在处理程序中获取它？

from google.appengine.ext.webapp import blobstore_handlers
class UploadHandler(blobstore_handlers.BlobstoreUploadHandler):
  def post(self):
    upload_files = self.get_uploads('file')
    blob_info = upload_files[0]
    self.redirect('/serve/%s' % blob_info.key())

Answer 1

你不希望它在post处理程序中。在文件上传后调用，但上传本身由App Engine内部处理。
