Android的錯誤FileNotFoundException異常

我想問一下爲什麼這個網絡連接會出現FileNotFoundException異常錯誤，我找了很多地方都沒有找到答案謝謝先Android的錯誤FileNotFoundException異常

public static void sendOldHttpRequest(final String address, final IHttpCallbackListenet httpCallbackListenet) { 
    new Thread(new Runnable() { 
     @Override 
     public void run() { 
      HttpURLConnection urlConnection = null; 
      try { 
       Log.i("tzf", "run: "+address); 
       URL url = new URL(address); 

       urlConnection = (HttpURLConnection) url.openConnection(); 
       InputStream inputStream = urlConnection.getInputStream(); 
       BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream)); 
       StringBuffer response = new StringBuffer(); 
       String line; 
       while ((line = reader.readLine()) != null) { 
        response.append(line); 
       } 

       httpCallbackListenet.onFinish(response.toString()); 

       reader.close(); 
       inputStream.close(); 

      } catch (Exception e) { 
       httpCallbackListenet.onError(e); 
      } finally { 

       if (urlConnection!=null){ 
        urlConnection.disconnect(); 
       } 
      } 
     } 
    }).start(); 
}

最有可能的，Android是正從'的https的HTTP 404響應：// moment.douban.com/API /流/日期/ 2017-03-05' 。我不知道爲什麼。 – CommonsWare

也許文件受到保護。或者試圖檢索文件的機器人會收到與用戶不同的結果。嘗試檢索一個HTML文件。打開一個流到google.com（或任何其他網站）並嘗試獲取索引文件 – Zoe

對HttpURLConnection將針對HTTP狀態代碼400及以上版本將拋出FileNotFoundException。讀取內容之前，您可以使用getResponseCode（）來檢查響應狀態碼。也許你的要求不好？或者您無權訪問請求的資源。

你可以做某事像這樣

InputStream inputStream; 
int responseStatusCode = urlConnection.getResponseCode(); 
if(status != HttpURLConnection.HTTP_OK) { 
    inputStream = urlConnection.getErrorStream(); 
    //Get more informations about the problem 
} else { 
    inputStream = urlConnection.getInputStream(); 
}

是的，但我可以在瀏覽器中訪問，但無法訪問Android，好奇啊...... –

您是否包含適當的權限清單文件？ – Bari

權限添加，因爲在HTTP403之前 –
