开始

默认情况下申请令牌访问oauth/token未携带client_secret参数时会返回Bad client credentials

如果直接通过AuthenticationEntryPoint是无法自定义返回的信息,我们需要重写过滤器ClientCredentialsTokenEndpointFilter

自定义过滤器

public class CustomClientCredentialsTokenEndpointFilter extends ClientCredentialsTokenEndpointFilter {

    private AuthorizationServerSecurityConfigurer configurer;
    private AuthenticationEntryPoint authenticationEntryPoint;

    public CustomClientCredentialsTokenEndpointFilter(AuthorizationServerSecurityConfigurer configurer) {
        this.configurer = configurer;
    }

    @Override
    public void setAuthenticationEntryPoint(AuthenticationEntryPoint authenticationEntryPoint) {
        // 把父类的干掉
        super.setAuthenticationEntryPoint(null);
        this.authenticationEntryPoint = authenticationEntryPoint;
    }

    @Override
    protected AuthenticationManager getAuthenticationManager() {
        return configurer.and().getSharedObject(AuthenticationManager.class);
    }

    @Override
    public void afterPropertiesSet() {
        setAuthenticationFailureHandler(new AuthenticationFailureHandler() {
            @Override
            public void onAuthenticationFailure(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, AuthenticationException e) throws IOException, ServletException {
                authenticationEntryPoint.commence(httpServletRequest, httpServletResponse, e);
            }
        });
        setAuthenticationSuccessHandler(new AuthenticationSuccessHandler() {
            @Override
            public void onAuthenticationSuccess(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Authentication authentication) throws IOException, ServletException {
                // 无操作-仅允许过滤器链继续到令牌端点
            }
        });
    }

}

自定义AuthenticationEntryPoint

@Component
public class CustomAuthenticationEntryPoint implements AuthenticationEntryPoint {

    private ObjectMapper objectMapper = new ObjectMapper();

    @Override
    public void commence(HttpServletRequest request, HttpServletResponse response, AuthenticationException e) throws IOException, ServletException {
        e.printStackTrace();
        response.setStatus(200);
        Result result = Result.buildFail(e.getMessage());
        response.setHeader("Content-Type", "application/json;charset=utf-8");
        response.getWriter().print(objectMapper.writeValueAsString(result));
        response.getWriter().flush();
    }

}

修改授权服务器配置

public class AuthorizationServerConfigurer extends AuthorizationServerConfigurerAdapter {

    @Autowired
    private AuthenticationEntryPoint authenticationEntryPoint;

    @Autowired
    private CustomUserDetailsService userDetailsService;

    @Override
    public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {
        CustomClientCredentialsTokenEndpointFilter endpointFilter = new CustomClientCredentialsTokenEndpointFilter(security);
        endpointFilter.afterPropertiesSet();
        endpointFilter.setAuthenticationEntryPoint(authenticationEntryPoint);
        security.addTokenEndpointAuthenticationFilter(endpointFilter);
        // 注意:security不需要在调用allowFormAuthenticationForClients方法
        security.authenticationEntryPoint(authenticationEntryPoint)
                .tokenKeyAccess("isAuthenticated()")
                .checkTokenAccess("permitAll()");
    }
    
    // 此处省略其他代码...

}
