假装客户端为Url抛出未经授权的异常，其中不需要身份验证

Question

我关注了这个博客，并创建了一些微服务:Eureka-server、Auth-service、Zuul-service、Gallery-service、image-service。从gallery服务中，我想使用Feign-Client调用auth-service API，url不需要身份验证，但是客户机抛出feignException$unauthorization，我使用JWT令牌进行身份验证。

//AuthServerProxy.java

@FeignClient(name = "auth-service")
@RibbonClient(name = "auth-service")
public interface AuthServiceProxy {

    @PostMapping("/auth/authenticate")
    public ResponseEntity<?> authenticate(@RequestBody UserEntity userEntity);

    @GetMapping("/auth/register")
    public String test();
}

@Autowired
    AuthServiceProxy authServiceProxy;
    @GetMapping("/test")
    public String test(){
        UserEntity userEntity = new UserEntity();
        userEntity.setUsername("admin");
        userEntity.setPassword("admin");
        ResponseEntity<?> responseEntity = authServiceProxy.authenticate(userEntity);
        System.out.println(responseEntity.getStatusCode());
        return responseEntity.toString();

    }

    @GetMapping("/test/str")
    public String testStr(){
        return authServiceProxy.test();
    }

.antMatchers(HttpMethod.POST, "/auth/authenticate").permitAll()

看起来身份验证标头没有通过FeignClient传递

尝试添加此配置：

@Bean
public RequestInterceptor requestInterceptor() {

    return requestTemplate -> {
        Authentication authentication = SecurityContextHolder.getContext().getAuthentication();

        if (authentication != null && authentication.getDetails() instanceof OAuth2AuthenticationDetails) {
            OAuth2AuthenticationDetails details = (OAuth2AuthenticationDetails) authentication.getDetails();
            requestTemplate.header(HttpHeaders.AUTHORIZATION, String.format("Bearer %s", details.getTokenValue()));
        }
    };
}
