错误不显示带有以下网址的图片

http://127.0.0.1:8080/serve/CrObzPCoJfjG4ESUUb0hjw==

可以在admin中检查blobstore中是否存在图像我的路线 Dope on redirect routes

RedirectRoute('/serve/[a-zA-Z0-9-_]', handlers.ServeHandler, name='ServeHandler'),

我的代码：

from google.appengine.ext import blobstore
from google.appengine.ext.webapp import blobstore_handlers

import urllib

class ServeHandler(blobstore_handlers.BlobstoreDownloadHandler):
  def get(self, resource):
    logging.info("SERVE " + str(resource))
    resource = str(urllib.unquote(resource))
    blob_info = blobstore.BlobInfo.get(resource)
    self.send_blob(blob_info)

class FetchHandler(blobstore_handlers.BlobstoreUploadHandler):
  def post(self):
    upload_files = self.get_uploads('file')  # 'file' is file upload field in the form
blob_info = upload_files[0]
logging.info("FOUND blob info" + str(blob_info))
self.redirect('/serve/%s' % blob_info.key())


class ImageHandler(BaseHandler):
    @user_required
    def get(self, **kwargs):
        user_session = self.user
        user_session_object = self.auth.store.get_session(self.request)
        upload_url = blobstore.create_upload_url('/fetch/')    

        user_info = models.User.get_by_id(long( self.user_id ))
        user_info_object = self.auth.store.user_model.get_by_auth_token(
            user_session['user_id'], user_session['token'])

        try:
            params = {
                "upload_url": upload_url,
                "user_session" : user_session,
                "user_session_object" : user_session_object,
                "user_info" : user_info,
                "user_info_object" : user_info_object,
                "userinfo_logout-url" : self.auth_config['logout_url'],
                }
            return self.render_template('image.html', **params)
        except (AttributeError, KeyError), e:
            return "Secure zone error:" + " %s." % e

Answer 1

我认为您提供给create_upload_url的网址是错误的，因为您将其定义为/upload/。

最后添加正斜杠，它应该可以工作：

upload_url = blobstore.create_upload_url('/upload/')

Answer 2

将您的代码（来自您的问题的早期版本）与我工作的某些代码进行比较，我怀疑您可能不希望在/upload/路由上使用尾随/（即使用/upload代替

但我不熟悉RedirectRoute。

Answer 3

我认为您的问题可能出在这一行：

 self.redirect('/serve/%s' % blob_info.key())

根据以下最近的更改，假设您更新了appengine到最新版本：

The Blobstore service now returns the created filename instead of the blobKey when using Cloud Storage [link][1]

查看recent release notes及其随附的更改。
