Question

我试图在app引擎上运行任务，但我收到以下错误：

ERROR    2012-07-24 18:47:01,030 wsgi.py:189] 
Traceback (most recent call last):
  File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/runtime/wsgi.py", line 187, in Handle
    handler = _config_handle.add_wsgi_middleware(self._LoadHandler())
  File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/runtime/wsgi.py", line 225, in _LoadHandler
    handler = __import__(path[0])
ImportError: No module named tasks
INFO     2012-07-24 18:47:01,040 dev_appserver.py:2952] "POST /tasks HTTP/1.1" 500 -
WARNING  2012-07-24 18:47:01,045 taskqueue_stub.py:1934] Task task22 failed to execute. This task will retry in 0.100 seconds

我这样做是为了添加任务：

import os
import webapp2
from google.appengine.ext.webapp import blobstore_handlers
from controllers.basehandler import BaseHandler
from google.appengine.ext import blobstore
from google.appengine.api import taskqueue
from google.appengine.ext.webapp.util import run_wsgi_app


class UploadHandler(blobstore_handlers.BlobstoreUploadHandler, BaseHandler):
    def post(self):
        upload_files = self.get_uploads('video_file')
        blob_info = upload_files[0]

        current_user = self.current_user

        if current_user:
            if current_user.video_file_bob:
                old_video = current_user.video_file_bob.key()
                blobstore.delete(old_video)

            current_user.video_file_bob = blob_info.key()
            current_user.put()

            params = {'user':current_user}

            taskqueue.add(url='/tasks')

        self.redirect('/video_upload')

app = webapp2.WSGIApplication([('/store_video', UploadHandler)],
                                     debug=True)

这是任务的代码：

import re
import urlparse
import webapp2
from google.appengine.ext import blobstore
from controllers.basehandler import BaseHandler
import gdata.youtube.service
from google.appengine.api import taskqueue
from google.appengine.ext.webapp.util import run_wsgi_app
import logging


class YoutubeUpload(BaseHandler):

    def post(self):
        logging.info('Here')


app = webapp2.WSGIApplication([('/tasks', YoutubeUpload)],
                                 debug=True)

关于如何解决这个问题的任何想法？

修改

我app.yalm的内容：

application: traapp
version: 1
runtime: python27
api_version: 1
threadsafe: True

handlers:
- url: /images
  static_dir: assets/images 
- url: /link_submit
  script: controllers.video_link_submit.app
- url: /video_upload
  script: controllers.video_upload.app
- url: /store_video
  script: controllers.video_upload_handler.app
- url: /tasks
  script: tasks.youtube_upload.app
  login: admin
- url: /.*
  script: controllers.login.app

libraries:
- name: PIL
  version: latest

builtins:
- appstats: on

Answer 1

它看起来像导入错误“ImportError：没有模块命名的任务”。所以我认为以下是不正确的。

- url: /tasks
  script: tasks.youtube_upload.app

问题中第二个区块的路径和文件名是什么？现在设置它的方式，您需要在/ tasks文件夹中包含youtube_upload.app，其中包含 init .py。
