Enabling CORS on Google App Engine Flexible environment for a Django Application

[Swapnil Tiwari]

Hi,

I have been trying to enable CORS on my Django application deployed on Google App Engine flexible environment but no luck. Here is my question on stack overflow with a lot more details - https://stackoverflow.com/questions/45934384/enabling-cors-on-google-app-engine-for-a-django-application

I have followed the January 2017 release notes over here - https://cloud.google.com/endpoints/docs/release-notes but no luck so far

Kindly help me

Regards,

Swapnil

You may refer to the "CORS Support" subchapter of the "app.yaml Reference" documentation page. 

Is your allow origin address correct? 

[Swapnil Tiwari]

Yes I did try the CORS example given in the link you just shared.

I added a handler to app.yaml like this:

handlers:
- url: /*
  http_headers:
    Access-Control-Allow-Origin: '*'

 

Then I ran - gcloud app deploy and got an error. I have attached the screenshot of the error

Also, the CORS subchapter says - "You can set HTTP headers for responses of your static file or directory handlers. If you need to set HTTP headers in your script handlers, you should instead do that in your app's code."

I don't want CORS to be enabled on static files. I want it on my REST APIs

You seem to have used the wildcard "*" between single quotes '*'. The error message complains about this URL, you should look into it.

Thanks for the reply Geore. Changing the url to a specific URL for example

-url:/api/v1/sign-up

also did not work

Based on the comments of this post, it looks like `static_dir` is required for using `http_headers`. It could be some outdated/bad documentation causing some confusion.

Hi Swapnil, 

Do you need any more help from us on this issue? You seem to have solved it, as one can read in your twin posting in stackoverflow.
