小编use*_*561的帖子

我正在使用GAE Python 2.7和本地开发服务器.我配置了一个后端

backends:
- name: worker
  class: B1
  options: dynamic

我正在使用默认的taskqueue.一切正常,后端和任务队列在SDK控制台上可见.本地开发工作也开始没有任何错误:

Multiprocess Setup Complete:
Remote API Server [http://localhost:9200]
App Instance [http://localhost:9000]
Backend Instance: worker.0 [http://localhost:9100]
Backend Balancer: worker [http://localhost:9199]

但是如果我尝试通过任务解决后端问题

taskqueue.add(url='/xyz', method='POST', target='worker', params={'a':'b'})

这个错误提出:

ERROR An error occured while sending the task "task1" (Url: "/backend/languages/create_database/") in queue "default". Treating as a task error.
