尽管＆＃34; https://jsonplaceholder.typicode.com/posts/1＆＃34;以下代码禁止403：在邮递员工作

@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：

如果有人可以建议我需要在我的代码中添加什么

尝试添加＆＃34; User-Agent＆＃34;标题为您的请求。您可以尝试设置自定义用户代理值，也可以使用一些标识浏览器的值，例如＆＃34; Mozilla / 5.0（Macintosh; Intel Mac OS X 10_11_6）AppleWebKit / 537.36（KHTML，如Gecko）Chrome / 51.0.2704.103 Safari浏览器/ 537.36＆＃34;

@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));
        headers.add("user-agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/54.0.2840.99 Safari/537.36");
        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);
    }
}
