内容图文

我有一个休息api,我在使用spring security Basic Authorization进行身份验证,其中客户端为每个请求发送用户名和密码.
现在,我想实现基于令牌的身份验证,我将在用户首先进行身份验证时在响应头中发送令牌.对于进一步的请求,客户端可以在标头中包含该标记,该标记将用于向用户验证资源.我有两个身份验证提供程序tokenAuthenticationProvider和daoAuthenticationProvider

@Component
public class TokenAuthenticationProvider implements AuthenticationProvider {

    @Autowired
    private TokenAuthentcationService service;

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

        final RequestAttributes requestAttributes = RequestContextHolder.getRequestAttributes();
        final HttpServletRequest request = ((ServletRequestAttributes) requestAttributes).getRequest();
        final String token = request.getHeader(Constants.AUTH_HEADER_NAME);
        final Token tokenObj = this.service.getToken(token);
        final AuthenticationToken authToken = new AuthenticationToken(tokenObj);
        return authToken;
    }

     @Override
        public boolean supports(final Class<?> authentication) {
            return AuthenticationToken.class.isAssignableFrom(authentication);
        }
}

在daoAuthenticationProvider中,我设置自定义userDetailsS??ervice并通过从数据库中获取用户登录详细信息进行身份验证(只要使用授权传递用户名和密码就可以正常工作：基本bGllQXBpVXNlcjogN21wXidMQjRdTURtR04pag ==作为标头)

但是当我使用X-AUTH-TOKEN(即Constants.AUTH_HEADER_NAME)在标头中包含token时,不会调用tokenAuthenticationProvider.我收到错误了

{"timestamp":1487626368308,"status":401,"error":"Unauthorized","message":"Full authentication is required to access this resource","path":"/find"}

以下是我添加身份验证提供程序的方法.

    @Override
    public void configure(final AuthenticationManagerBuilder auth) throws Exception {

        final UsernamePasswordAuthenticationProvider daoProvider = new 

UsernamePasswordAuthenticationProvider(this.service, this.passwordEncoder());
    auth.authenticationProvider(this.tokenAuthenticationProvider);
    auth.authenticationProvider(daoProvider);
} 

请建议如何在不损害spring安全性的当前行为的情况下实现基于令牌的身份验证.

解决方法:

以下是我能够实现基于令牌的身份验证和基本身份验证的方法

SpringSecurityConfig.java

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter
{

    @Override
    public void configure(final AuthenticationManagerBuilder auth) throws Exception
    {
        auth.userDetailsService(this.participantService).passwordEncoder(this.passwordEncoder());
    }

    @Override
    protected void configure(final HttpSecurity http) throws Exception
    {

        //Implementing Token based authentication in this filter
        final TokenAuthenticationFilter tokenFilter = new TokenAuthenticationFilter();
        http.addFilterBefore(tokenFilter, BasicAuthenticationFilter.class);

        //Creating token when basic authentication is successful and the same token can be used to authenticate for further requests
        final CustomBasicAuthenticationFilter customBasicAuthFilter = new CustomBasicAuthenticationFilter(this.authenticationManager() );
        http.addFilter(customBasicAuthFilter);

    }
}

TokenAuthenticationFilter.java

    public class TokenAuthenticationFilter extends GenericFilterBean
    {


        @Override
        public void doFilter(final ServletRequest request, final ServletResponse response, final FilterChain chain)
                throws IOException, ServletException
        {
            final HttpServletRequest httpRequest = (HttpServletRequest)request;

             //extract token from header
            final String accessToken = httpRequest.getHeader("header-name");
            if (null != accessToken) {
           //get and check whether token is valid ( from DB or file wherever you are storing the token)

          //Populate SecurityContextHolder by fetching relevant information using token
               final User user = new User(
                            "username",
                            "password",
                            true,
                            true,
                            true,
                            true,
                            authorities);
                    final UsernamePasswordAuthenticationToken authentication =
                            new UsernamePasswordAuthenticationToken(user, null, user.getAuthorities());
                    SecurityContextHolder.getContext().setAuthentication(authentication);

            }

            chain.doFilter(request, response);
        }

      }

CustomBasicAuthenticationFilter.java

@Component
public class CustomBasicAuthenticationFilter extends BasicAuthenticationFilter {


    @Autowired
    public CustomBasicAuthenticationFilter(final AuthenticationManager authenticationManager) {
        super(authenticationManager);
    }

    @Override
    protected void onSuccessfulAuthentication(final javax.servlet.http.HttpServletRequest request, final javax.servlet.http.HttpServletResponse response, final Authentication authResult) {
        //Generate Token
        //Save the token for the logged in user
        //send token in the response
        response.setHeader("header-name" , "token");


    }

}

由于我们的CustomBasicAuthenticationFilter已经配置并添加为弹簧安全性的过滤器,

每当基本身份验证成功时,请求将被重定向到onSuccessfulAuthentication,我们在其中设置令牌并将其发送到响应中,并带有一些标题“header-name”.

如果发送“header-name”以进一步请求,则在尝试尝试基本身份验证之前,请求将首先通过TokenAuthenticationFilter.
