解析JSON，這是在Android應用程序中的HTML中的標籤

我的問題是一點點不同，我想，我以前問：Parse JSON to cofigure android application 我有json來自服務器，當我看它在瀏覽器源代碼;這是什麼樣子解析JSON，這是在Android應用程序中的HTML中的標籤

JOSON.config：

<html> 
<head></head> 
<body> 
<pre> 
[ 

    { 
     "sett": " ", 
     "glHdr": {

        } 
       ], 
       "st": "sm" 
      }, 
      {

     ],

功能掃描JSON：

public void doScanAppConfigJson(){ 


      JSONArray appConfig = null; 

      // Function for looping json object via ParseJson class. 
      //Creating JSON Parser instance 
      JSONParser jParser = new JSONParser(); 

      //Getting json strings from url 
      JSONObject jsonObject = jParser.getJSONFromUrl(url); 

     try{ 
      //Getting array of settings 
      appConfig = jsonObject.getJSONArray(ConfigConstants.TABLE_VIEW_SUB_MENU_CONFIG); 
      //loop throw all the objects under -sm[] 
      for (int i = 0; i < appConfig.length(); i++){ 

       JSONObject sm = appConfig.getJSONObject(i); 

       //Now store each of this json in local constant var. 

       String tabTitle = sm.getString(TAG_TITLE); 

       String webAddress = sm.getString(TAG_WEB_ADDRESS); 

       String screenType = sm.getString(TAG_SCREEN_TYPE); 

       String fileName = sm.getString(TAG_FILENAME); 

      } 

     }catch (JSONException e){ 
      e.printStackTrace(); 

     } 

     }

getJsonFromUrl方法：

公衆的JSONObject getJSONFromUrl（字符串URL）{

//Global authentication for link username and password. 
    Authenticator.setDefault(new Authenticator() { 
     protected PasswordAuthentication getPasswordAuthentication(){ 

     return new PasswordAuthentication("username", "password".toCharArray()); 
     } 

    }); 

    // Making HTTP request 
    try { 
     // defaultHttpClient 
     DefaultHttpClient httpClient = new DefaultHttpClient(); 
     HttpPost httpPost = new HttpPost(url); 

     HttpResponse httpResponse = httpClient.execute(httpPost); 
     HttpEntity httpEntity = httpResponse.getEntity(); 
     is = httpEntity.getContent();   

    } catch (UnsupportedEncodingException e) { 
     e.printStackTrace(); 
    } catch (ClientProtocolException e) { 
     e.printStackTrace(); 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } 

    try { 
     BufferedReader reader = new BufferedReader(new InputStreamReader(
       is, "iso-8859-1"), 8); 
     StringBuilder sb = new StringBuilder(); 
     String line = null; 
     while ((line = reader.readLine()) != null) { 
      sb.append(line + "\n"); 
     } 
     is.close(); 
     json = sb.toString(); 
    } catch (Exception e) { 
     Log.e("Buffer Error", "Error converting result " + e.toString()); 
    } 

    // try parse the string to a JSON object 
    try { 
     jObj = new JSONObject(json); 
    } catch (JSONException e) { 
     Log.e("JSON Parser", "Error parsing data " + e.toString()); 
    } 

    // return JSON String 
    return jObj; 

}

和錯誤即時得到是：http://cl.ly/image/0z1u2v30341G

現在我猜它的bcz的html文檔類型或別的什麼，但我找不到什麼是錯的。

問：如何解析這個JSON並將其存儲在局部變量中？（我沒有選擇更改服務器端的JSON）在此先感謝。

如果你可以配置服務器停止包裝它在html標籤，這將是理想的。 – 2013-03-27 00:20:27

@SamDufel：我沒有選擇更改服務器端代碼！我可以在應用程序中做些什麼來避免這個標籤並閱讀json？ – star18bit 2013-03-27 00:22:36

這和你以前的問題有什麼不同？ – cbrulak 2013-03-27 04:50:18

那麼你可以提取子字符串，從開放「[」開始，直到關閉「]」，然後分析它作爲JSON，使你的getJSONFromUrl()方法的變化：

public void getJSONFromUrl() { 
    ... 
    ... 

    json = sb.toString().substring(html.indexOf("["), html.lastIndexOf("]") + 1); 

    ... 
}
