google-app-engine - 将 AppEngine 后端转换为模块时出现问题

Question

我正在尝试将使用后端的 AppEngine 应用程序转换为使用模块的应用程序(按照 Google 的建议)。

我用 backends_conversion.py app.yaml backends.yaml 转换了 backends.yaml

期间 appcfg.py 更新 producer.yaml

然后我收到错误，版本“producer”已经存在，我应该更改模块名称。

我没有那样做(因为我使用模块名称作为任务队列目标)。相反，我停止并删除了正在运行的后端版本。

上传之后工作的模块。

但是排队任务(通过任务队列)不起作用(即没有启动模块的实例)。

同时尝试从浏览器 (producer.appid.appspot.com) 访问该模块会生成一个 http 503。

怎么了？

[更新] 我们正在明确地处理后端:

taksqueue.add(..., target='producer')

taskqueue 文档没有说明如何使用模块。

一种方法:您可以设置您的 dispatch file这样您的某些任务处理程序就会被路由到特定的模块。 注意:对 dispatch.yaml 文件进行更改后，您需要运行

appcfg.py update_dispatch <proj_dir>
