Python应用程序引擎队列任务

Question

我试图运行在App Engine任务，但我发现了以下错误：

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) 

如何解决这个任何想法？

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

    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

它看起来像一个导入错误 “导入错误：没有模块名为任务”。所以我会认为以下是不正确的。

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

第二块在你的问题中的路径和文件名是什么？现在你已经设置了它的方式，你需要在其中有一个init .py的/ tasks文件夹中包含youtube_upload.app。
