Spring Security Popup Opening

Question

Someone knows how to open a pop-up login for authentication (using spring security) when a user does something that needs to be authenticated, but he doesn’t.

For example: Suppose that there is one “buy now” button on the page that adds the product to the cart and performs a check (purchase now) if the user has already authenticated or opens an authentication pop-up window for the user.

If the authentication was successful, and spring is redirected to the "buy now" page or remains on this page with a pop-up opening (with the error message "wrong entry").

I already searched on google for a kind of solution, but no luck.

Can someone point me in the right direction?

thank

Answer 1

Just an idea, did not have time to test it. This is only the client side.

• Place the Eventlistener on the Link / Button-Click-Event
• Use Javascript and call the action form or link through XMLHttpRequest
• Check the HTTP status code: xhr.status
• if (OK) replace the current URL with the destination URL ( via the Html5 history API ) and replace the entire document with xhr.responseText( Other options for replacing the entire HTML document through the W3C DOM )
• else if (Redirect) just follows the migration
• else if (Unauthorized) open popup

Spring , SavedRequestAwareAuthenticationSuccessHandler, , do, URL- (, - <intercept-url pattern = "/purchase/*" access = "isAuthenticated()" /> ( access = "hasRole('user'), ) ( "/purchase/"productIdHere" /purchase?productId=someProductId), . , :

@Controller
...

@RequestMapping(value = "/purchase..., method = ....)
public ModelAndView purchase(@PathVariable("productId") String/Long productId (or @RequestParam etc...)
Product someProduct = someService.getByProductId(productId);
ModelAndView mav = new ModelAndView("view.name");
mav.setObject("product",product);
return mav;
