Getting the POST variables in OAuth2Provider.AuthenticateAsync

ServiceStack Authentication
1

Hi,

I have an update issue when updating from ServiceStack 8.0.0 to 8.3.0.
I have created an own OAuthProvider, inheriting from OAuth2Provider. In the function AuthenticateAsync there is the Authenticate request object. This one used to have the properties oauth_token, qop and State. I misused them in my application. These properties are removed in version 8.3.0.

But my frontend is sending these as a post variable. I would expect to be able to retrieve them with e.g.:
var qop = authService.Request.FormData[“qop”];
but here the NameValueCollection FormData is empty.

Is there a way to get the POST variables in the call /auth/MyOAuth in the overridden function AuthenticateAsync of OAuth2Provider?

Cheers,
Paul

That is the way to access the Request FormData but not sure why it would be empty, are you sure you’re posting a application/x-www-form-urlencoded Content-Type? Is Request.QueryString empty as well?

My Content-Type is application/json. Does that matter?
The Request,QueryString is also empty in the debugger. Things like the RawUrl are filled in.

JSON isn’t FormData, which needs to send either a application/x-www-form-urlencoded or multipart/form-data Content-Type, i.e. the same request a HTML Form would post.

If you want to keep a JSON Request Body I’d recommend adding the missing property to the queryString.

Ah, ok. I must have hit this problem before. Thanks for pointing me out.
I’ll add a new custom route for this endpoint, convert the request and send it on with ResolveService. I didn’t realize that option before. So thanks for answering my stupid questions :slight_smile:
