Accessing the registration page with UAA [v4.9.0]

Overview of the issue

When using JHipster 4.9.0 and UAA, there is an issue with accessing the registration page. There is 401 Unauthorized error in the browser’s console (as the result of the GET request to http://localhost:8080/uaa/api/account).

Motivation for or Use Case

Registrations should be possible in the out of the box, generated version.

Reproduce the error

You have to generate an app with UAA through JHipster 4.9.0.

I’m not aware of this.

Suggest a Fix

There were a changes in UAA recently. From the first overview I found generator-jhipster/generators/client/templates/angular/src/main/webapp/app/shared/auth/_user-route-access-service.ts as the reason of the problem.

Previously when the route had no authorities, checkLogin was not executed. Problem has to be related with principal.identity(), executed inside checkLogin.

The quickfix for me was to copy

if (!authorities || authorities.length === 0) {
    return true;
}

back to its original place, but it was moved from there for a purpose

// We need to call the checkLogin / and so the principal.identity() function, to ensure,
// that the client has a principal too, if they already logged in by the server.
// This could happen on a page refresh.

I’d say, the target solution requires a better understanding of principal.identity() and rethinking it with the recently registered user in mind.

So…option 3: “AntiUserRouteAccessService” 😆

I’ve moved the lines, because of #6190 and #6413 . The register route should have an opposite rule - if the user logged in, they shouldn’t be allowed to see the page
