Отображение JSONObject в Rest Template для получения аутентификации в весенней безопасности

Question

Мне нужно сделать POST-запрос к / user / auth с телом json 'username' и 'password' для получения аутентификации пользователя из конечной точки безопасности Spring.

У меня есть форма входа в систему thymeleaf. он отправляет 'username' и 'password' в мою конечную точку пользовательского фильтра аутентификации.

Конечная точка запускается, но объект, который она получает, является нулевым.

Я могу использовать почтальон дляотправьте тело json в конечную точку, и я смогу войти в систему с успехом, но при использовании формы тимили, отправляемый мною объект является нулевым.

Что-то, что я пробовал: использование конечной точки перед аутентификацией для перехвата запросаи обрабатывает объект тимелист в JSON. Я думаю, что мне не хватает того, как использовать RestTemplate, хотя.

    @PostMapping(value = "/preauth", produces = "application/json")
    @ResponseBody
    public UserDto preAuth(@ModelAttribute LoginRequestModel loginRequestModel) {
        log.info("username to test: {}", loginRequestModel.getUsername());
        log.info("password to test: {}", loginRequestModel.getPassword());
// ^^ these are coming back correct ^^


        JSONObject jsonObject = new JSONObject();
        jsonObject.put("username", loginRequestModel.getUsername());
        jsonObject.put("password", loginRequestModel.getPassword());

jsonObject.toMap().forEach((s, o) -> System.out.println(s + " : " + o));

// ^^ this also comes back correct ^^
// dont understand how to get this JSONObject inserted into the Rest Template

        RestTemplate restTemplate = new RestTemplate(jsonObject);

        restTemplate.exchange("http://localhost:8080/user/auth", loginRequestModel, LoginRequestModel.class);

        return userInfo;

    }

<form action="#" method="POST" th:action="@{/user/auth/preauth}" th:object="${loginRequestModel}">
    <p>Username: <input th:field="*{username}" type="text"/></p>
    <p>Password: <input th:field="*{password}" type="text"/></p>
    <p><input type="submit" value="Submit"/> <input type="reset" value="Reset"/></p>

public class AuthenticationFilter extends UsernamePasswordAuthenticationFilter {
@Override
    public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response) throws AuthenticationException {

        log.info("attempting to authenticate user");
        try {
            log.info("trying to map object");
            LoginRequestModel creds = new ObjectMapper()
                    .readValue(request.getInputStream(), LoginRequestModel.class);


            return getAuthenticationManager().authenticate(
                    new UsernamePasswordAuthenticationToken(
                            creds.getUsername(),
                            creds.getPassword(),
                            new ArrayList<>()
                    )
            );

        } catch (IOException e) {

            throw new RuntimeException(e);
        }

    }

по любой причине, request.getInputStream () возвращается как ноль, когда я пытаюсь вызвать его непосредственно из формы тимили в браузере.

Answer 1

Я исправил это! просто нужно было отправить объект thymeleaf конечной точке preauth и использовать HttpServletRequest для request.login () с именем пользователя и паролем непосредственно из html. не требуется сопоставление с JSON.

 @PostMapping(value = "/preauth", produces = "application/json")
    public String preAuth(@ModelAttribute LoginRequestModel loginRequestModel, HttpServletRequest request) throws IOException, ServletException {

        request.login(loginRequestModel.getUsername(),loginRequestModel.getPassword());

        return "index";

    }

Answer 2

Я думаю, вы должны получить userName и password, как показано ниже, когда вы используете UsernamePasswordAuthenticationToken

 @Override
 public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response)
        throws AuthenticationException {
    // TODO Auto-generated method stub
    request.getSession().setMaxInactiveInterval(sessionTimeout);

    CustomUsernamePasswordAuthenticationToken authRequest = getAuthRequest(request);
    _log.info("");
    setDetails(request, authRequest);

    return this.getAuthenticationManager().authenticate(authRequest);
}

    private CustomUsernamePasswordAuthenticationToken getAuthRequest(HttpServletRequest request) {
         String username = obtainUsername(request);
     String password = obtainPassword(request);
    _log.info("UserName IN Filter : "+username);
    _log.info("UserName IN Filter : "+password);

    return new CustomUsernamePasswordAuthenticationToken(username, password);
}
