Question

我在获取授权码后尝试使用Instagram的访问令牌api获取访问令牌。

我使用以下代码从访问令牌url api获取访问令牌。

httpurl参数：

https://api.instagram.com/oauth/access_token?client_id=CLIENT_ID&client_secret=CLIENT_SECRET&grant_type=authorization_code&redirect_uri=http://localhost:8080/Insta_SMI_M1/auth&code=CODE

代码

     public String getAccessToken(String httpurl){
        try {
                URL url = new URL(httpurl);
                HttpURLConnection conn = (HttpURLConnection) url.openConnection();
                conn.setDoOutput(true);

                BufferedReader  rd = new BufferedReader(
                new InputStreamReader(conn.getInputStream()));
                String result="";
                String line;
                while ((line = rd.readLine()) != null) {
                    result+=line;
                    System.out.println(line);
                }
                return result;
             } catch (Exception e) {
                 System.out.println(e.toString());
               }
        return "Hello";
    }

它给了我以下错误

java.io.IOException: Server returned HTTP response code: 405 for URL: https://api.instagram.com/oauth/access_token?client_id=cf07d1a2c69940e59420b6db4c936f4a&client_secret=fb0a975ca2024a1592459308df5ead47&grant_type=authorization_code&redirect_uri=http://localhost:8080/Insta_SMI_M1/auth&code=b520236c3ceb4f40a3d4c31aa0b3ff84

我经历了这个405 response code instagram access token api，但仍然没有运气。

任何帮助都会非常感激。感谢

问题是curl正在执行POST请求，但我的代码正在执行GET请求。

以下是发布请求的代码。

 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";

 }
