通过app-engineendpointapi服务blobstore映像

Question

from google.appengine.api import files

def save_image(data):
  # Create the file
  file_name = files.blobstore.create(mime_type='image/png')

  # Open the file and write to it
  with files.open(file_name, 'a') as f:
    f.write('data')

  # Finalize the file. Do this before attempting to read it.
  files.finalize(file_name)

  # Get the file's blob key
  blob_key = files.blobstore.get_blob_key(file_name)
  return blob_key # which is then saved to datastore

from google.appengine.ext import blobstore
from google.appengine.ext.webapp import blobstore_handlers
class ServeHandler(blobstore_handlers.BlobstoreDownloadHandler):
  def get(self, resource):
    resource = str(urllib.unquote(resource))
    blob_info = blobstore.BlobInfo.get(resource)
    self.send_blob(blob_info)

将图像添加到StuffResponseMessage

发送StuffResponseMessage到前端（android应用）

我的做法是因为我想保护我的用户的隐私。对如何做好这件事有什么想法吗？我的代码片段通常来自google developer Tutorial。

from google.appengine.ext import blobstore
from google.appengine.ext.webapp import blobstore_handlers
class ServeHandler(blobstore_handlers.BlobstoreDownloadHandler):
  def get(self, resource):
    resource = str(urllib.unquote(resource))
    blob_info = blobstore.BlobInfo.get(resource)
    self.send_blob(blob_info)

resource里面有什么？
