在Google Cloud Endpoints中返回自定义HTTP错误原因

Question

Google's own REST APIs return detailed response in case of an error, eg:

{
 "error": {
  "errors": [
   {
"domain": "global",
"reason": "invalidBookshelfId",
"message": "Invalid bookshelf ID."
   }
  ],
  "code": 400,
  "message": "Invalid bookshelf ID."
 }
}

In Google Cloud Endpoints for Python, it's possible to eg raise endpoints.BadRequestException('Error message') , but in addition to the error message I would like to return "code" or "reason" as in example above. Is there any way to achieve this?

Answer 1

The code corresponds to the status code associated with BadRequestException . The other exceptions are documented as well, for example endpoints.UnauthorizedException corresponds to the status code 401 . As for the reason and the domain , those are set by Google's API Infrastructure.

What did you have in mind that isn't possible to set in message ?
