我的问题与我想的略有不同，我之前问过：Parse JSON to cofigure android application 我有来自服务器的 json，当我在浏览器源代码中查看它时；这就是它的样子

JOSON.config：

扫描json的函数：

   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：

公共 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;

}

我得到的错误是：http ://cl.ly/image/0z1u2v30341G

现在我猜它是 html doctype 或其他东西的 bcz，但我找不到什么问题。

问：如何解析这个 JSON 并将其存储在局部变量中？（我没有为 json 更改服务器端的选项）提前致谢。

好吧，您可以从打开 ' [ ' 直到关闭 ' ] ' 提取子字符串，然后将其解析为 json，在您的getJSONFromUrl()方法中进行更改：

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

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

     ...
}
