google.appengine.api.yaml_errors.EventError: Unexpected attribute "http_headers" for mapping type script.

[Tom Wu]

Hi Pros,

Here is my demos/sample_app/module_A/app.yaml

....

handlers:

- url: .*

  script: _go_app

  http_headers:

    Access-Control-Allow-Origin: http://127.0.0.1:8080

goapp serve demos/sample_app/module_A/app.yaml

google.appengine.api.yaml_errors.EventError: Unexpected attribute "http_headers" for mapping type script.

Best Regards

I don't think you can use app.yaml to control HTTP headers for dynamic
handlers; that's only for static file handlers. Set the header within
your app code.

Thanks David, I got it.

That's horrible. I wonder what the rationale is?
