403スプリングブートAPI呼び出しで403禁止されたエラー？

Question

Springbootを使用してREST APIを使用しようとしています。今、私は郵便配達員からapiをテストしましたが、すべて正常に動作するようですが、私はPOSTMANを介してAPIを呼び出します。私は403禁じられたエラーを得ています。 APIはJSON形式でレスポンスを返し、POSTMANでテストしたところ、すべて正常に動作しているようです。

Through Postman, I am adding headers as key-value and its a get request 
"user-key": "*********"

public String getdata(){ 
     String url = "https://developers.zomato.com/api/v2.1/categories"; 

     RestTemplate rs = new RestTemplate(); 
     HttpHeaders headers = new HttpHeaders(); 
     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"); 

     // headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON)); 
     headers.setContentType(MediaType.APPLICATION_JSON); 
     headers.set("user-key", "*********"); 
     String consumeJSONString = rs.getForObject(url, String.class); 


     return consumeJSONString ; 






    }

Answer 1

あなたはちょうどそれらを宣言するヘッダを送信していません。このような

何か作業をする必要があります：

HttpEntity<String> entity = new HttpEntity<String>(headers); 

rs.exchange(url, HttpMethod.GET, entity, String.class);
