Spring Security Cookie + JWT身份验证

Question

我必须说我对整个模型非常困惑,我需要帮助将所有漂浮的部分粘在一起.

我不是在做Spring REST,只是简单的WebMVC控制器.

我的使命:我希望使用用户名+通过身份验证进行表单登录.我想对第三方服务进行身份验证.成功后我想返回一个cookie但不使用默认的cookie令牌机制.我想让cookie改为使用JWT令牌.通过利用cookie机制,每个请求都将与JWT一起发送.

因此,为了打破它,我有以下模块来照顾:

1. 在执行用户+操作登录时对第三方服务进行身份验证

2. 成功验证后,使用我的自定义实现替换cookie会话令牌

3. 每个请求从cookie中解析JWT(使用过滤器)

4. 从JWT中提取用户详细信息/数据,以便控制器可以访问

什么令人困惑？(请纠正我错在哪里)

第三方认证

要对第三方进行身份验证,我需要通过扩展AuthenticationProvider来获得自定义提供程序

public class JWTTokenAuthenticationProvider implements AuthenticationProvider { 

      @Override
      public Authentication authenticate( Authentication authentication ) throws AuthenticationException {

          // auth against 3rd party

          // return Authentication
          return new UsernamePasswordAuthenticationToken( name, password, new ArrayList<>() );

      }

      @Override
      public boolean supports(Class<?> authentication) {
          return authentication.equals( UsernamePasswordAuthenticationToken.class );
      }

}

问题:

• 当用户提交表单user + pass时,是否在成功验证/登录时执行此提供程序？如果是这样,那与AbstractAuthenticationProcessingFilter#successfulAuthentication有什么关系呢？
• 我是否必须返回UsernamePasswordAuthenticationToken的实例？
• 我是否必须支持UsernamePasswordAuthenticationToken以获取用户+通过此处？

用JWT替换cookie令牌

不知道如何优雅地做到这一点,我可以想到多种方式,但他们不是Spring Security方式,我不想打破流程.非常感谢这里的任何建议!

使用cookie的每个请求解析JWT

根据我的理解,我需要像这样扩展AbstractAuthenticationProcessingFilter

public class CookieAuthenticationFilter extends AbstractAuthenticationProcessingFilter {

    @Override
    public Authentication attemptAuthentication( HttpServletRequest request, HttpServletResponse response )
            throws AuthenticationException, IOException, ServletException {

        String token = "";

        // get token from a Cookie

        // create an instance to Authentication
        TokenAuthentication authentication = new TokenAuthentication(null, null);

        return getAuthenticationManager().authenticate(tokenAuthentication);

    }

    @Override
    public void doFilter(ServletRequest req, ServletResponse res,
                     FilterChain chain) throws IOException, ServletException {
        super.doFilter(req, res, chain);
    }

}

问题:

• 什么时候是AbstractAuthenticationProcessingFilter#successfulAuthentication叫？是用户登录还是成功验证JWT令牌？
• 这个过滤器和我之前发布的自定义提供程序之间有任何关系吗？管理员应该根据令牌实例调用自定义提供程序,该实例与提供程序通过支持方法支持的内容相匹配？

似乎我拥有了我需要的所有部分,除了cookie会话替换,但是我不能将它们放入一个连贯的模型中,我需要从那些理解机制的人那里得到足够好的所以我可以将所有这些都粘合到一个单独的模块中.

更新1

好的,我想我正在开始这个地方...... https://github.com/spring-projects/spring-security/blob/master/web/src/main/java/org/springframework/security/web/认证/ UsernamePasswordAuthenticationFilter.java

此过滤器将自身注册到POST - >"/ login",然后创建UsernamePasswordAuthenticationToken的实例,并将控件传递给下一个过滤器.

问题是cookie会话设置的地方....

更新2

dos的这一部分提供了我所缺少的顶级流程,无论是谁通过这个看看这里...... http://docs.spring.io/spring-security/site/docs/current/reference/ htmlsingle /#高科技的开场认证

有关AuthenticationProvider的此部分... http://docs.spring.io/spring-security/site/docs/current/reference/htmlsingle/#core-services-authentication-manager

更新3 - 工作案例,这是最好的方法吗？

因此,在深入了解Spring Security文档及其来源后,我得到了初始模型.现在,这样做,我意识到有不止一种方法可以做到这一点.任何建议为什么采取这种方式VS丹尼斯提出下面提出的？

下面的工作示例......

Answer 1

为了让它按照原始帖子中描述的方式工作,这就是需要发生的事情......

定制过滤器

public class CookieAuthenticationFilter extends AbstractAuthenticationProcessingFilter {

        public CookieAuthenticationFilter( RequestMatcher requestMatcher ) {

            super( requestMatcher );
            setAuthenticationManager( super.getAuthenticationManager() );

        }

        @Override
        public Authentication attemptAuthentication( HttpServletRequest request, HttpServletResponse response )
            throws AuthenticationException, IOException, ServletException {

            String token = "";

            // get token from a Cookie
            Cookie[] cookies = request.getCookies();

            if( cookies == null || cookies.length < 1 ) {
                throw new AuthenticationServiceException( "Invalid Token" );
            }

            Cookie sessionCookie = null;
            for( Cookie cookie : cookies ) {
                if( ( "someSessionId" ).equals( cookie.getName() ) ) {
                sessionCookie = cookie;
                break;
                }
            }

            // TODO: move the cookie validation into a private method
            if( sessionCookie == null || StringUtils.isEmpty( sessionCookie.getValue() ) ) {
                throw new AuthenticationServiceException( "Invalid Token" );
            }

            JWTAuthenticationToken jwtAuthentication = new JWTAuthenticationToken( sessionCookie.getValue(), null, null );

            return jwtAuthentication;

        }


        @Override
        public void doFilter(ServletRequest req, ServletResponse res,
                 FilterChain chain) throws IOException, ServletException {
            super.doFilter(req, res, chain);
        }

}

认证提供商

将提供程序附加到UsernamePasswordAuthenticationFoken,UsernamePasswordAuthenticationFilter将自己附加到"/ login"POST.对于带有POST到"/ login"的formlogin,将生成UsernamePasswordAuthenticationToken,并且将触发您的提供者

@Component
public class ApiAuthenticationProvider implements AuthenticationProvider {

        @Autowired
        TokenAuthenticationService tokenAuthService;

        @Override
        public Authentication authenticate( Authentication authentication ) throws AuthenticationException {

            String login = authentication.getName();
            String password = authentication.getCredentials().toString();

            // perform API call to auth against a 3rd party

            // get User data
            User user = new User();

            // create a JWT token
            String jwtToken = "some-token-123"

            return new JWTAuthenticationToken( jwtToken, user, new ArrayList<>() );

        }

        @Override
        public boolean supports( Class<?> authentication ) {
                return authentication.equals( UsernamePasswordAuthenticationToken.class );
        }
}

自定义验证对象

对于JWT,我们希望拥有自己的身份验证令牌对象来携带我们想要的堆栈数据.

public class JWTAuthenticationToken extends AbstractAuthenticationToken {

        User principal;
        String token;

        public JWTAuthenticationToken( String token, User principal, Collection<? extends GrantedAuthority> authorities ) {
            super( authorities );
            this.token = token;
            this.principal = principal;
        }

        @Override
        public Object getCredentials() {
            return null;
        }

        @Override
        public Object getPrincipal() {
            return principal;
        }

        public void setToken( String token ) {
            this.token = token;
        }

        public String getToken() {
            return token;
        }
}

身份验证成功处理程序

当我们的自定义提供程序通过向第三方验证用户并生成JWT令牌来执行此操作时,就会调用此命令,这是Cookie进入响应的位置.

@Component
public class AuthenticationSuccessHandler extends SavedRequestAwareAuthenticationSuccessHandler {

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

        if( !(authentication instanceof JWTAuthenticationToken) ) {
            return;
        }

        JWTAuthenticationToken jwtAuthenticaton =    (JWTAuthenticationToken) authentication;

        // Add a session cookie
        Cookie sessionCookie = new Cookie( "someSessionId", jwtAuthenticaton.getToken() );
        response.addCookie( sessionCookie );

        //clearAuthenticationAttributes(request);

        // call the original impl
        super.onAuthenticationSuccess( request, response, authentication );
}

}

将这一切联系在一起

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired @Required
    ApiAuthenticationProvider apiAuthProvider;

    @Autowired @Required
    AuthenticationSuccessHandler authSuccessHandler;

    @Autowired @Required
    SimpleUrlAuthenticationFailureHandler authFailureHandler;

    @Override
    protected void configure( AuthenticationManagerBuilder auth ) throws Exception {
    auth.authenticationProvider( apiAuthProvider );
    }

    @Override
    protected void configure( HttpSecurity httpSecurity ) throws Exception {

            httpSecurity

            // don't create session
            .sessionManagement()
                .sessionCreationPolicy( SessionCreationPolicy.STATELESS )
                .and()

            .authorizeRequests()
                .antMatchers( "/", "/login", "/register" ).permitAll()
                .antMatchers( "/js/**", "/css/**", "/img/**" ).permitAll()
                .anyRequest().authenticated()
                .and()

            // login
            .formLogin()
                .failureHandler( authFailureHandler )
                //.failureUrl( "/login" )
                .loginPage("/login")
                .successHandler( authSuccessHandler )
                        .and()

            // JWT cookie filter
            .addFilterAfter( getCookieAuthenticationFilter(
                    new AndRequestMatcher( new AntPathRequestMatcher( "/account" ) )
            ) , UsernamePasswordAuthenticationFilter.class );
    }


    @Bean
    SimpleUrlAuthenticationFailureHandler getAuthFailureHandler() {

            SimpleUrlAuthenticationFailureHandler handler = new SimpleUrlAuthenticationFailureHandler( "/login" );
            handler.setDefaultFailureUrl( "/login" );
            //handler.setUseForward( true );

            return handler;

    }

    CookieAuthenticationFilter getCookieAuthenticationFilter( RequestMatcher requestMatcher ) {

            CookieAuthenticationFilter filter = new CookieAuthenticationFilter( requestMatcher );
            filter.setAuthenticationFailureHandler( authFailureHandler );
            return filter;
    }
}

Answer 2

最简单的方法是将 Spring Session 添加到您的项目中并扩展HttpSessionStrategy ，它为会话创建/销毁事件提供方便的挂钩，并具有从 HttpServletRequest 中提取会话的方法。
