基于自定义令牌的身份认证

Question

我已经阅读了这个问题的公认答案，并创建了一个自定义令牌、过滤器和身份验证提供程序。

问题：

当我尝试“获取/登录”时：

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;
    }
}

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;
    }
}

@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，请参见Spring Security参考：

筛选器调用配置的AuthenticationManager来处理每个身份验证请求。

另请参见AbstractauthEnticationProcessingFilter#AttreathEntication:

null
