Spring SecurityとJSON認証

私は完全にJSON通信を使用するspring/spring-mvcのアプリケーションを持っています。ここで、JSONを介してSpring Security 3（LdapAuthenticationProviderを使用）でアプリケーションを認証する必要があります。

デフォルトの春の安全性送信フォームには、次のようなPOSTが必要です。

POST /myapp/j_spring_security_check HTTP/1.1
Accept-Encoding: gzip,deflate
Content-Type: application/x-www-form-urlencoded
Content-Length: 32
Host: 127.0.0.1:8080
Connection: Keep-Alive
User-Agent: Apache-HttpClient/4.1.1 (Java 1.5)

j_username=myUsername&j_password=myPass

しかし、私はこのようなJSONオブジェクトを渡したいです：

{"j_username":"myUsername","j_password":"myPass"}

this 、 this other 、または this one のような多くの投稿を読みました。すべてのajaxの場合はPOST上記のように。

何か案は？

JSONを解析する独自のセキュリティフィルターを作成できます。

http://docs.spring.io/spring-security/site/docs/3.0.x/reference/core-web-filters.html

BasicAuthenticationFilterを参照として使用できます。

ケビンの提案によると、
そしてこの投稿を読んだ後： 1 、 2 、ドキュメント、そして this に感謝ブログ投稿、
認証前にJSONを直接管理する独自のFORM_LOGIN_FILTERを作成しました。
コミュニティにコードを貼り付けます。

目標は、古典的なブラウザ形式の両方を許可することですPOST JSONベースの認証を使用した認証。JSON認証でもloginSuccesful.htmへのリダイレクトを回避したい

ログインリクエストに別のリクエストボディパーサーが必要な場合は、UsernamePasswordAuthenticationFilterを拡張し、attemptAuthenticationメソッドをオーバーライドします。デフォルトでは、UsernamePasswordAuthenticationFilterはURLエンコードされたデータを解析し、そこからUsernamePasswordAuthenticationTokenを作成します。ここで、アプリケーションに送信するものをすべて解析するパーサーを作成するだけです。

{"username": "someusername", "password": "somepassword"}を解析する例を次に示します

public class CustomUsernamePasswordAuthenticationFilter extends UsernamePasswordAuthenticationFilter {

    @Override
    public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response) throws AuthenticationException {
        try {
            BufferedReader reader = request.getReader();
            StringBuffer sb = new StringBuffer();
            String line = null;
            while ((line = reader.readLine()) != null) {
                sb.append(line);
            }
            String parsedReq = sb.toString();
            if (parsedReq != null) {
                ObjectMapper mapper = new ObjectMapper();
                AuthReq authReq = mapper.readValue(parsedReq, AuthReq.class);
                return new UsernamePasswordAuthenticationToken(authReq.getUsername(), authReq.getPassword());
            }
        } catch (Exception e) {
            System.out.println(e.getMessage());
            throw new InternalAuthenticationServiceException("Failed to parse authentication request body");
        }
        return null;
    }

    @Data
    public static class AuthReq {
        String username;
        String password;
    }

}

スニペットリクエストの本文は文字列に抽出され、オブジェクトAuthReqにマッピングされます（@Dataアノテーションはロンボクlibからのもので、セッターとゲッターを生成します）。デフォルトのUsernamePasswordAuthenticationTokenに渡されるAuthenticationProviderを作成できるよりも。

これで、WebSecurityConfigurerAdapterを拡張し、cnofigureメソッドをオーバーライドして古いフィルターを置き換えることができます。

@Override
protected void configure(HttpSecurity http) throws Exception {
    http
        .authorizeRequests()
            .antMatchers("/", "/login", "/logout").permitAll()
            .anyRequest().authenticated()
        .and().addFilterAt(new CustomUsernamePasswordAuthenticationFilter(), UsernamePasswordAuthenticationFilter.class)
        .formLogin().loginProcessingUrl("/login")
        .and()
        .csrf().disable();
}

addFilterAtメソッドを使用して、デフォルトのUsernamePasswordAuthenticationFilterを置き換えます。 @EnableWebSecurityアノテーションを使用することを忘れないでください。

this postによる別の方法は、コントローラーで直接スプリングセキュリティ認証を手動で管理することです。
この方法では、JSON入力を管理し、ログインリダイレクトを回避するのが非常に簡単です。

@Autowired
AuthenticationManager authenticationManager;

@ResponseBody
@RequestMapping(value="/login.json", method = RequestMethod.POST)
public JsonResponse mosLogin(@RequestBody LoginRequest loginRequest, HttpServletRequest request) {
    JsonResponse response = null;

    try {
        UsernamePasswordAuthenticationToken token = new UsernamePasswordAuthenticationToken(loginRequest.getUsername(), loginRequest.getPassword());
        token.setDetails(new WebAuthenticationDetails(request));

        Authentication auth = authenticationManager.authenticate(token);
        SecurityContext securityContext = SecurityContextHolder.getContext();
        securityContext.setAuthentication(auth);

        if(auth.isAuthenticated()){
            HttpSession session = request.getSession(true);
            session.setAttribute("SPRING_SECURITY_CONTEXT", securityContext);

            LoginResponse loginResponse = new LoginResponse();
            loginResponse.setResponseCode(ResponseCodeType.SUCCESS);
            response = loginResponse;   
        }else{
            SecurityContextHolder.getContext().setAuthentication(null);

            ErrorResponse errorResponse = new ErrorResponse();
            errorResponse.setResponseCode(ResponseCodeType.ERROR);
            response = errorResponse;
        }   
    } catch (Exception e) {     
        ErrorResponse errorResponse = new ErrorResponse();
        errorResponse.setResponseCode(ResponseCodeType.ERROR);
        response = errorResponse;           
    }
    return response;
}

Spring BootアプリケーションでJSON資格情報を使用してログインする場合、 fl4l および oe.elvik からの回答を適用しました。注釈ベースのBean構成で作業しています。

参照された回答では、認証マネージャーが挿入されるカスタムフィルターが作成されます。これを行うには、認証マネージャーがSpring Beanとして存在する必要があります。これを行う方法のリンクは次のとおりです。 https://stackoverflow.com/a/21639553/3950535 。

上記のソリューションのJava構成：

@Override

    http.csrf().disable()
            .addFilterBefore(authenticationFilter(),UsernamePasswordAuthenticationFilter.class)
            .authorizeRequests()
            .anyRequest().authenticated()
            .and()
            .formLogin()
            .loginPage("/login")
            .permitAll();
}

@Bean
public AuthenticationFilter authenticationFilter() throws Exception{
    AuthenticationFilter authenticationFilter = new AuthenticationFilter();
    authenticationFilter.setUsernameParameter("username");
    authenticationFilter.setPasswordParameter("password");
    authenticationFilter.setAuthenticationManager(authenticationManager());
    authenticationFilter.setFilterProcessesUrl("/login");
    authenticationFilter.setAuthenticationSuccessHandler(successHandler());
    return authenticationFilter;
}

@Bean
public SuccessHandler successHandler(){
    return new SuccessHandler();
}
