[Exception] Using the SpringSecurity of the Ruoyi framework reports an error, prompting "Access requested: /ci/card/testPost, authentication failed, unable to access system resources"

1. Error screenshot

Using the Spring Security of the Ruoyi framework to report an error, when initiating a Post request call, it prompts "Request access: /ci/card/testPost, authentication failed, unable to access system resources", but the Get request can be released normally.

2. Error description

2.1 Complete Request Situation

@RestController
@RequestMapping(value = "/ci/card")
@Slf4j
@AllArgsConstructor
public class IndexLibraryController extends BaseController {
    
    

    @ResponseBody
    @GetMapping(value = "/testGet", produces = "application/json")
    public String testGet() {
    
    
        return "123";
    }

    @ResponseBody
    @PostMapping(value = "/testPost", produces = "application/json")
    public String testPost() {
    
    
        return "123";
    }
}

@ResponseBody
    @PostMapping(value = "/testPost", produces = "application/json")
    public String testPost() {
    
    
        return "123";
    }

2.2 Test 1: Use get request and return normally

@ResponseBody
@GetMapping(value = "/testGet", produces = "application/json")
public String testGet() {
    
    
    return "123";
}

2.3 Test 2: Use post request, abnormal return

@ResponseBody
@PostMapping(value = "/testPost", produces = "application/json")
public String testPost() {
    
    
    return "123";
}

2.4 Check the error point and locate the code

/**
 * 认证失败处理类 返回未授权
 * 
 * @author ruoyi
 */
@Component
public class AuthenticationEntryPointImpl implements AuthenticationEntryPoint, Serializable
{
    
    
    private static final long serialVersionUID = -8970718410437077606L;

    @Override
    public void commence(HttpServletRequest request, HttpServletResponse response, AuthenticationException e)
            throws IOException
    {
    
    
        int code = HttpStatus.UNAUTHORIZED;
        String msg = StringUtils.format("请求访问：{}，认证失败，无法访问系统资源", request.getRequestURI());
        ServletUtils.renderString(response, JSON.toJSONString(AjaxResult.error(code, msg)));
    }
}

2.5 Check the calling location

/**
* 认证失败处理类
*/
@Autowired
private AuthenticationEntryPointImpl unauthorizedHandler;

@Override
protected void configure(HttpSecurity httpSecurity) throws Exception {
    
    
	httpSecurity
			// CSRF禁用，因为不使用session
			.csrf().disable()
			// 认证失败处理类
			.exceptionHandling().authenticationEntryPoint(unauthorizedHandler).and()
	//其他配置略
}

The inspection found that only GET requests are fully released, but post requests are not released.

.antMatchers(
		HttpMethod.GET,
		"/",
		"/*.html",
		"/**/*.html",
		"/**/*.css",
		"/**/*.js",
		"/ci/**"
).permitAll()

Three, error resolution

Just increase the release of the post request.

.antMatchers(
		HttpMethod.POST,
		"/",
		"/ci/**"
).permitAll()

The complete Spring Security configuration is as follows

@Override
protected void configure(HttpSecurity httpSecurity) throws Exception {
    
    
	httpSecurity
			// CSRF禁用，因为不使用session
			.csrf().disable()
			// 认证失败处理类
			.exceptionHandling().authenticationEntryPoint(unauthorizedHandler).and()
			// 基于token，所以不需要session
			.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS).and()
			// 过滤请求
			.authorizeRequests()
			// 对于登录login 注册register 验证码captchaImage 允许匿名访问
			.antMatchers("/login", "/register", "/captchaImage").anonymous()
			.antMatchers(
					HttpMethod.GET,
					"/",
					"/*.html",
					"/**/*.html",
					"/**/*.css",
					"/**/*.js",
					"/ci/**"
			).permitAll()
			.antMatchers(
					HttpMethod.POST,
					"/",
					"/ci/**"
			).permitAll()
			.antMatchers("/common/download**").anonymous()
			.antMatchers("/common/download/resource**").anonymous()
			.antMatchers("/swagger-ui.html").anonymous()
			.antMatchers("/swagger-resources/**").anonymous()
			.antMatchers("/webjars/**").anonymous()
			.antMatchers("/*/api-docs").anonymous()
			.antMatchers("/druid/**").anonymous()
			.antMatchers("/ObjectLoggerServer/**").permitAll()
			// 除上面外的所有请求全部需要鉴权认证
			.anyRequest().authenticated()
			.and()
			.headers().frameOptions().disable();
	httpSecurity.logout().logoutUrl("/logout").logoutSuccessHandler(logoutSuccessHandler);
	// 添加JWT filter
	httpSecurity.addFilterBefore(authenticationTokenFilter, UsernamePasswordAuthenticationFilter.class);
	// 添加CORS filter
	httpSecurity.addFilterBefore(corsFilter, JwtAuthenticationTokenFilter.class);
	httpSecurity.addFilterBefore(corsFilter, LogoutFilter.class);
