java - 收到 403 禁止错误

标签 java spring restful-url resttemplate

<分区>

尽管“https://jsonplaceholder.typicode.com/posts/1”在 postman 中有效,但以下代码禁止获取 403

@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

最佳答案

尝试将“User-Agent” header 添加到您的请求中。您可以尝试设置自定义用户代理值或使用一些标识浏览器的值,例如“Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.103 Safari/537.36 "

@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);
    }
}
