得到403禁止错误

获得403禁止下面的代码，虽然 “https://jsonplaceholder.typicode.com/posts/1” 的邮递员工作得到403禁止错误

@ComponentScan 
@EnableAutoConfiguration 
public class Application { 
    public static void main(String[] args) { 

     RestTemplate rt = new RestTemplate(); 
     HttpHeaders headers = new HttpHeaders(); 
     headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON)); 
     HttpEntity<String> entity = new HttpEntity<String>("parameters", headers); 
     String url = "https://jsonplaceholder.typicode.com/posts/1"; 
     ResponseEntity<String> res = rt.exchange(url, HttpMethod.GET, entity, String.class); 

     System.out.println(res); 
    } 
}

错误：

什么是您的发帖人头值？或尝试ResponseEntity res = rt.exchange（url，HttpMethod.POST，entity，String.class）; – kuhajeyan

403禁止表示您的用户无权执行此操作，也没有用户有权执行此操作。如果这是对'邮递员'的工作，那么当你插入你的验证头时会出现问题。 –
