在Android的Reddit集成

我使用它的API實現了reddit集成。下面是我的登錄代碼到reddit的：在Android的Reddit集成

private void LoginMethod(){ 

     String jsonString = ""; 
     DefaultHttpClient httpclient = new DefaultHttpClient(); 

     final ArrayList<NameValuePair> fields = new ArrayList<NameValuePair>(3); 
     fields.add(new BasicNameValuePair("user", "test"));//will ask for a user to enter the password later 
     fields.add(new BasicNameValuePair("passwd", "test11")); 
     fields.add(new BasicNameValuePair("api_type", "json")); 

     final HttpPost request = new HttpPost("https://ssl.reddit.com/api/login"); 

     try { 
      request.setEntity(new UrlEncodedFormEntity(fields, HTTP.UTF_8)); 

      HttpResponse response = httpclient.execute(request); 
      HttpEntity entity = response.getEntity(); 

      jsonString = EntityUtils.toString(entity); 

      System.out.println("response from redit = " + jsonString); 

      JSONObject jObject = new JSONObject(jsonString); 
      modhash = jObject.getJSONObject("json").getJSONObject("data").getString("modhash"); 
     } catch (UnsupportedEncodingException e) { 
      e.printStackTrace(); 
     } catch (ClientProtocolException e) { 
      e.printStackTrace(); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } catch (JSONException e) { 
      e.printStackTrace(); 
     } 

}

使用上面的方法，它唯一的作品有時，大多得到響應象下面這樣：

我不知道如何處理這類問題。我已經做了R & D，但沒有太多的細節或例子可用於reddit集成。

那麼，有助於解決這個錯誤。

我應該在我的代碼中更改哪些內容？ – Riser 2015-02-10 12:00:03

從API文檔：

Make no more than thirty requests per minute

你將會在這個數字，因此您的申請將被拒絕。

發生這種情況時，向用戶顯示一條消息以解釋他必須等待。沒有解決方法。 – 2015-02-10 12:01:30

除了安東尼奧MG的回答，您應該設置一個自定義的用戶代理，每reddit API rules：

「很多默認的用戶代理（如‘巨蟒/ urllib的’或」 Java「）受到嚴格限制，鼓勵使用獨特和描述性的用戶代理字符串。」

至少，它應該包括聯繫信息的reddit工作人員聯繫，如有必要。按要求，它應該是這樣的形式：

<platform>:<app ID>:<version string> (by /u/<reddit username>)

例如

android:com.example.myredditapp:v1.2.3 (by /u/kemitche)

最後，你應該認真考慮使用OAuth 2進入reddit的的API，而不是直接登錄; "cookie" authentication is scheduled for deprecation。

你可以給一個OAuth2登錄的例子在Android？ – Riser 2015-02-11 05:30:11

我會推薦代碼流，並請求刷新令牌。更多信息在OAuth2流reddit：https://github.com/reddit/reddit/wiki/OAuth2 – kemitche 2015-02-11 19:29:43

我已經看到這從最近3天，但不知道如何登錄並提交一個鏈接使用。 – Riser 2015-02-12 04:54:39
