从 BlobstoreUploadHandler 获取当前用户 [英] Get the current user from BlobstoreUploadHandler
问题描述
I want to get the current user from BlobstoreUploadHandler. I'm using endpoints for my web application, but (outside of Endpoints) I built /uploadUrl to upload files to the Blobstore.
The image uploads correctly. So, I need to link the image uploaded to the user, but users.get_current_user() returns None. On the frontend side the user is logged using OAuth2. Any idea for this issue?
If I use endpoints.get_current_user() raise an error:
No valid endpoints user in environment
This is my code:
class UploadHandler(blobstore_handlers.BlobstoreUploadHandler):
def post(self):
upload_files = self.get_file_infos()
file_info = upload_files[0]
gcs_filename = file_info.gs_object_name
file_key = blobstore.create_gs_key(gcs_filename)
File(file=gcs_filename, owner=users.get_current_user() ).put()
Each App requires its own login, and every class needs to have users imported and declared if you want to use User class in the code.
from google.appengine.api import users import webapp2
class MyHandler(webapp2.RequestHandler):
def get(self):
user = users.get_current_user()
if user:
greeting = ('Welcome, %s! (<a href="%s">sign out</a>)' %
(user.nickname(), users.create_logout_url('/')))
else:
greeting = ('<a href="%s">Sign in or register</a>.' %
users.create_login_url('/'))
self.response.out.write('<html><body>%s</body></html>' % greeting)
