Pass Authentication Headers via printURL.

[kieranbarlow]

Is it possible to pass headers to the printURL() method? I'm testing printd in a single page application and the endpoint is locked behind JWT authentication.

I could attach the token to the url.

https://endpoint/api/testing?token=JWT TOKEN

I feel a more elegant approach would be better.

No, it's no possible. Because if you see we are setting the URL directly to the iframe. So I think your query token solution is suitable for.

But afterwards (after page load) you can do it for future requests if you want via the callback.

Remember that the callback receives those params above. So , for example you can leverage the iframe param and append all headers you want.

Solution from your side

Use a custom XHR request for fetch the page using your headers and then pass just the content to the iframe via print() method.
