基于自定义令牌的身份验证

Question

我正在尝试基于请求标头中的自定义令牌进行身份验证。

我已阅读this question 接受的答案并创建了自定义令牌、过滤器和身份验证提供程序。

问题：

当我尝试“获取/登录”时：

• 过滤器被调用
• 令牌已创建
• 未调用 authenticationProvider。甚至它的方法supports 也没有被调用！

在浏览器控制台中，我可以看到 2 个HTTP 302 调用/login。

有什么想法吗？

EDIT ：实际上，只有当我从 Angular 调用端点（导致 AJAX/XHR 调用）时，身份验证提供程序才会被忽略。如果我从 Postman 调用端点，则会调用身份验证提供程序。

令牌：

public class MyToken extends AbstractAuthenticationToken {

    private String token;

    public MyToken(String token) {
        super(null);
        this.token = token;
    }

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

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

过滤器：

public class MyFilter extends AbstractAuthenticationProcessingFilter {

    public MyFilter() {
        super("/login");
    }

    @Override
    public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response) throws AuthenticationException, IOException, ServletException {
        String x_token = request.getHeader("x_token");
        String method = request.getMethod();
        if(x_token != null && method.equals("GET")) {
            return new MyToken(x_token);
        }
        return null;
    }
}

身份验证提供者：

@Component
public class MyAuthenticationProvider implements AuthenticationProvider {
    @Override
    public Authentication authenticate(Authentication authentication) throws AuthenticationException {
        MyToken token = (MyToken) authentication;
        if(token.getCredentials() != null) {
            token.setAuthenticated(true);
            return token;
        }
        return null;
    }

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

最后，安全配置：

@Configuration
@EnableGlobalMethodSecurity(prePostEnabled = true)
@Order(SecurityProperties.ACCESS_OVERRIDE_ORDER)
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Autowired
    private MyAuthenticationProvider myAuthenticationProvider;

    @Override
    protected void configure( HttpSecurity http ) throws Exception {
        // configure filters
        http.addFilterBefore( new MyFilter(), UsernamePasswordAuthenticationFilter.class );

        // configure authentication providers
        http.authenticationProvider(myAuthenticationProvider);

        // disable csrf
        http.csrf().disable();

        // setup security
        http.authorizeRequests()
                .anyRequest()
                .fullyAuthenticated()
                .and().httpBasic();
    }
}

Answer 1

您必须在AbstractAuthenticationProcessingFilter 的自定义子类中调用AuthenticationManager，参见Spring Security Reference：

过滤器调用配置的AuthenticationManager来处理每个认证请求。

另见AbstractAuthenticationProcessingFilter#attemptAuthentication：

执行实际身份验证。 实现应该执行以下操作之一：

1. 为经过身份验证的用户返回填充的身份验证令牌，表示身份验证成功
2. 返回null，表示认证过程仍在进行中。在返回之前，实施应执行完成流程所需的任何额外工作。
3. 如果身份验证过程失败，则抛出 AuthenticationException

您的实现未返回经过身份验证的令牌，请参阅日志：

SecurityContext 存储到 HttpSession: 'org.springframework.security.core.context.SecurityContextImpl@17085d: Authentication: com.mycompany.myapp.configuration.MyToken@17085d: Principal: null;凭证：[受保护]； 认证：假;详细信息：空；未授予任何权限

• UsernamePasswordAuthenticationFilter
• OpenIDAuthenticationFilter
