Hi,
I'm having a problem with authentication. I want to have token validation by login in my Angular app, but when I make post request, it keeps sending option method (preflight request) and I get 404 error with "The Same Origin Policy disallows reading the remote resource...Reason: CORS preflight channel did not succeed). In Postman it works just fine and I have no problem getting session id there. Does this sound familiar?

What's an example pre-flight request that is failing? Most of them should be hooked up, so I would like to see which specifically is being called.

This is a security rule employed by most most moderns browsers in the CORS definition.
Basically, the OPTION preflight request will apply if :
(I assume that your request is a POST with the content-type set to application/xml or application/json)
But it's not a problem, it's a safety measure. You just have to configure your server to respond to OPTION request with a status 200 and a header "Access-Control-Allow-Origin: *"
What is your backend setup ?

This is my post request
It sends pre-flight request, but it's not clear to me what should I do and is there a way to solve this without proxy and is this desirable behavior?

OPTIONS
is enabled on most (was supposed to be all ) endpoints but indeed, it was not enabled on the/3/authentication
endpoints. I have a deploy going out later today that will enable it. I'll let you know when it's live.Antwort von dankesn

OPTIONS should be enabled now on the
/3/authentication
methods. Let me know if you run into any more trouble.Antwort von dankesn
