Question

인증 코드를 얻은 후 instagram의 액세스 토큰 api를 사용하여 액세스 토큰을 얻으려고합니다.

httpurl 인수 : 그것은 여전히 ​​나는이 405 response code instagram access token api 통해 갔다 오류

curl이 POST 요청을하고 있지만 내 코드가 GET 요청을하고 있습니다.

다음은 게시물 요청을 수행하는 코드입니다.

public String accessTkn (String code) 
{ 
    try { 

     HttpClient httpclient = HttpClients.createDefault(); 
     HttpPost httppost = new HttpPost("https://api.instagram.com/oauth/access_token"); 

     // Request parameters and other properties. 
     List<NameValuePair> params = new ArrayList<NameValuePair>(2); 
     params.add(new BasicNameValuePair("client_id", Constants.CLIENT_ID)); 
     params.add(new BasicNameValuePair("client_secret", Constants.CLIENT_SECRET)); 
     params.add(new BasicNameValuePair("grant_type", "authorization_code")); 
     params.add(new BasicNameValuePair("redirect_uri", Constants.REDIRECT_URI_AUTH)); 
     params.add(new BasicNameValuePair("code", code)); 


     httppost.setEntity(new UrlEncodedFormEntity(params, "UTF-8")); 

     //Execute and get the response. 
     HttpResponse response = httpclient.execute(httppost); 
     HttpEntity entity = response.getEntity(); 
     System.out.println("entity "+ entity.getContent()); 

     if (entity != null) { 
      InputStream instream = entity.getContent(); 
      try { 

       return (getStringfromStream(instream)); 
       // do something useful 
      } finally { 
       instream.close(); 
      } 
     } 
    } catch (UnsupportedEncodingException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } catch (ClientProtocolException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } catch (UnsupportedOperationException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } catch (IOException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } 

    return "Abhay"; 

}
