Description

Currently, if CsrfViewMiddleware encounters a bad CSRF token, it will reject the request with a message like--

  • "CSRF token incorrect"
  • "CSRF token has incorrect length"

I noticed that it would be relatively easy to include in these messages whether the token was obtained from POST data or a custom header, which would be useful for troubleshooting. The new messages could look e.g. like--

  • "CSRF token (from POST) incorrect"
  • "CSRF token (from 'X-CSRFToken' header) has incorrect length"

The changes to CsrfViewMiddlewareTestMixin proposed in #32800 would make these cases easy to test.
