GWTP网守

Question

我做了一些来自GWTP的例子

http://blog.arcbees.com/2015/10/27/gwtp-beginners-tutorial-toaster-launcher-part-2/#Gatekeeper

@DefaultGatekeeper
public class LoggedInGatekeeper implements Gatekeeper {
    private CurrentUser currentUser;

    @Inject
    public LoggedInGatekeeper(CurrentUser currentUser) {
        this.currentUser = currentUser;
    }

    @Override
    public boolean canReveal() {
        return currentUser.isLoggedIn();
    }
}

在这里，如果用户是登录用户，我们将提供访问权限。

有没有可能找出想要使用哪个页面(NameToken)？以及是否给予他权限，这取决于权限

当然，只需将一个PlaceManager注入到您的LoggedInGatekeeper中，调用getCurrentPlaceRequest，然后将其与您的NameToken进行比较。大致是这样的：

@DefaultGatekeeper
public class LoggedInGatekeeper implements Gatekeeper {
    private CurrentUser currentUser;
    private PlaceManager placeManager;

    @Inject
    public LoggedInGatekeeper(CurrentUser currentUser, PlaceManager placeManager) {
        this.currentUser = currentUser;
        this.placeManager = placeManager;
    }

    @Override
    public boolean canReveal() {
        PlaceRequest request = placeManager.getCurrentPlaceRequest();
        if (request.hasSameNameToken('someNameToken') {

           return currentUser.isLoggedIn();
        }
        return true;
    }
}
