Issue

I need to redirect based on referer querystring after handle provider callback

startRedirectPath need to be added before the server started. So, it should be a static fixed path.
Maybe something like /login/:provider is possible, you may investigate in it.

@climba03003 Maybe I did't express clear, for example, if i set startRedirectPath to /login/github, and /login?redirect_to=/ is my website login page，there is a button which request /login/github when clicked, after auth the user, I want to redirect to the / based on the querystring, i can't get the initial request referer because the plugin handled the request and I don't know whether it expose the referer data.

generateStateFunction can intercept the initial request, but you need to find a way to match the initial request and callback route.

If you manage to use it to achieve what you mention. Remember to return the state inside generateStateFunction and also pass checkStateFunction to verify the generated state.

@climba03003 thx, it works, maybe this is another usage scenario of custom state, although it's initial purpose is secure concern
