通过RESTendpoint进行Spring Security身份验证/授权

Question

在我使用RESTful webservices的Spring Boot应用程序中，我将Spring Security与Spring Social和SpringSocialConfigurer一起html" target="_blank">配置了。

现在我有两种身份验证/授权方式--通过用户名/密码和通过社交网络，比如Twitter。

为了通过Spring MVC REST控制器中自己的RESTfulendpoint实现身份验证/授权，我添加了以下方法：

@RequestMapping(value = "/login", method = RequestMethod.POST)
public Authentication login(@RequestBody LoginUserRequest userRequest) {
    Authentication authentication = authenticationManager.authenticate(new UsernamePasswordAuthenticationToken(userRequest.getUsername(), userRequest.getPassword()));
    boolean isAuthenticated = isAuthenticated(authentication);
    if (isAuthenticated) {
        SecurityContextHolder.getContext().setAuthentication(authentication);
    }
    return authentication;
}

private boolean isAuthenticated(Authentication authentication) {
    return authentication != null && !(authentication instanceof AnonymousAuthenticationToken) && authentication.isAuthenticated();
}

但我不确定在成功调用endpoint后必须返回给客户机的内容是什么/login。我认为返回完整的身份验证对象是多余的。

在成功验证的情况下，应该向客户端返回什么？

能否请您告诉我如何正确实现这种登录方式？

另外，如果是RESTfull登录，我将使用UsernamePasswordAuthenticationToken，如果是通过Twitter登录，我将使用SocialAuthenticationToken，在同一个应用程序中使用不同的令牌可以吗？

您可以通过重写SimpleUrlAuthenticationSuccessShandler中的方法来配置成功身份验证时返回的内容

public class CustomAuthenticationSuccessHandler extends SimpleUrlAuthenticationSuccessHandler {

    public CustomAuthenticationSuccessHandler() {
        super();
        setRedirectStrategy(new NoRedirectStrategy());
    }

    @Override
    public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response,
            Authentication authentication) throws IOException, ServletException {

        super.onAuthenticationSuccess(request, response, authentication);
        ObjectMapper mapper = new ObjectMapper();

        response.setContentType("application/json;charset=UTF-8");
        response.getWriter().print(mapper.writeValueAsString(objectToBereturned);
        response.getWriter().flush();
    }

    protected class NoRedirectStrategy implements RedirectStrategy {

        @Override
        public void sendRedirect(HttpServletRequest request, HttpServletResponse response, String url)
                throws IOException {
            // any redirect if required. leave the implementation black if not needed
        }

    }
}

此外，您还可以处理失败响应：

public class CustomAuthenticationFailureHandler extends SimpleUrlAuthenticationFailureHandler {
    @Override
    public void onAuthenticationFailure(HttpServletRequest request, HttpServletResponse response,
            AuthenticationException exception) throws IOException, ServletException {
        response.setStatus(HttpServletResponse.SC_UNAUTHORIZED);
    }
}
