将自定义错误页面放在Google App Engine的何处

Question

I would like to add a custom error page on my GAE service.

From the document , it doesn't mention where to put the error page.

Here is my app.yaml file:

handlers:
- url: /static
  static_dir: static

- url: .*
  script: mega_jav.wsgi.application

error_handlers:
- file: error_default.html

- error_code: over_quota
  file: error_over_quota.html

And I put my both error_default.html and error_over_quota.html in my templates folder.

It doesn't work.

Where should I put the error page into? or can I modify the app.yaml file to make it works?

Thank you very much.

I suggest you read the docs https://cloud.google.com/appengine/docs/python/config/appconfig?hl=en#Python_app_yaml_Custom_error_responses

It's pretty clear, the error handler referers to a file but not a static resource (in fact there is an explicit warning to not make the file overlap with the static handlers (I raised the issue with the docs in 2010 as it didn't note this fact, causing deployment problems - https://code.google.com/p/googleappengine/issues/detail?id=3759 )

Warning: Make sure that the path to the error response file does not overlap with static file handler paths.

The page for the error handler is deployed in your code base.

And it has nothing to do with templates. Though it's path could be in your templates. However its is purely static html/text that is served if there is an uncaught error, putting it in your templates could be a source of confusion as it's not a template.

The simplest place in is the root of your project. The file directive is a relative path not a handler
