Serializing flask response

[mekanix]

I need to set cookies with on some endpoints. Just returning jsonify({ 'key': 'value' }) does not get serialized. Is there a way to set a cookie in the response together with the "normal" endpoint response?

Can you elaborate on your use case?

Since this is about REST APIs, I assume it is an authentication cookie, right?

Do you want to set it from the view function? From a custom authentication decorator?

[mekanix]

Yes, it's auth cookie. So, with flask_restplus this is the code I used: https://github.com/mekanix/backend-startkit/blob/master/application/api/auth.py#L21-L64. Something I tried to achieve with flask_rest_api is this: https://github.com/mekanix/backend-startkit/blob/feature/rest-api/application/api/auth.py#L24-L68. The problem is that frontend says length of response is wrong (I suppose I'm overwriting something).

I don't see anything blocking you from setting a cookie from a decorator.

However, setting a cookie from a view function is currently impossible because by design of the response method, the view function can not return a flask Response object. This is discussed in #22.

IIUC, the return resp.get_json() in your code means you're returning only the json body of the response and not the cookies.

Than decorator is the right place. :) Can you please post the code snippet to achieve it? The code I linked to is not the way I have to solve it, it just the closest I've got to setting the cookie, so feel free to just ignore it.

[lafrech]

I have no available snippet and no time for this right now.

You might find the conversation in #36 interesting, especially this comment.

Closing this for now. Feel free to comment if you're still stuck on this.
