android - JSONExecption 未终止的字符串 - Android

Question

我正在构建一个连接到博客的应用程序，然后以 JSON 格式收集数据。目前我遇到了这个错误(很抱歉所有 JSON 数据都不确定是否包括在内):Exception Caught org.json.JSONException: Unterminated string at character 6564 of {"status":"ok","count":20,"count_total":1727,"pages":87,"posts":[{"id":23419,"url":"http:\/\/blog.teamtreehouse.com\/happy-mothers-day-ones-whove-shaped-web-careers","title":"Happy Mother\u2019s Day!

这是捕获错误的地方:

public void updateList() {
        if (mBlogData == null) {
            // TODO: Handle Error
        }
        else {
            try {
            Log.d(TAG, mBlogData.toString(2));
            }
            catch (JSONException e) {
                Log.e(TAG, "Exception Caught", e);
            }
        }
    }

我不确定是什么导致了这个错误，所以欢迎提出任何建议。如果需要，我可以提供更多代码。谢谢。

只是想添加到 eMad 的答案中，它帮助我解决了你遇到的同样的问题。我希望这对任何追随我的人有所帮助，因为这个该死的 bug 杀死了我一天中的 2 个小时(或晚上，我是夜间 Activity 的)。好吧，没有进一步(ado？再见？)，给你:P.S.下面的代码将进入您的私有(private)类(class) GetBlogPostsTask AsynnTask...

protected JSONObject doInBackground(Object... arg0) {
        int responseCode = -1;
        JSONObject jsonResponse = null;

        try {
            //set API URL
            URL blogFeedUrl = new URL("http://blog.teamtreehouse.com/api/get_recent_summary/?    count=" + NUMBER_OF_POSTS);

            //open URL connection
            URLConnection connection = blogFeedUrl.openConnection();
            //create BufferedReader to read the InputStream return from the connection
            BufferedReader in = new BufferedReader(
                    new InputStreamReader ( connection.getInputStream() )
            );

            //initiate strings to hold response data
            String inputLine;
            String responseData = "";
            //read the InputStream with the BufferedReader line by line and add each line to responseData
            while ( ( inputLine = in.readLine() ) != null ){
                responseData += inputLine;
            }

            //check to make sure the responseData is not empty
            if( responseData!= "" ){
                /*initiate the jsonResponse as a JSONObject based on the string values added
                 to responseData by the BufferedReader */
                jsonResponse = new JSONObject(responseData);
            }

            /*return the jsonResponse JSONObject to the postExecute() method
            to update the UI of the context */
            return jsonResponse;
        }
        catch (MalformedURLException e) {
            Log.e(TAG, "Exception caught: ", e);
        }
        catch (IOException e) {
            Log.e(TAG, "Exception caught: ", e);
        }
        catch (Exception e) {
            Log.e(TAG, "Exception caught: ", e);
        }

        return jsonResponse;
    }

    @Override
    protected void onPostExecute(JSONObject result) {
        /* set the class' member JSONObject mBlogData to the result
         to be used by the handleBlogResponse() method to update the UI */
        mBlogData = result;
        /*call the handleBlogResponse() method to update the UI with the result of this AsyncTask
          which will be a JSONObject in best case scenario or a null object in worst case */
        handleBlogResponse();
    }
