从Wordpress文章URL获取Json

Question

我正试图从Wordpress文章URL获取Json，注意我在Json中并不擅长，并找到了一些代码，使用这些代码我能够获得帖子等等，但我想要的是从文章网址获取信息，而不是网站的主页面。使用此代码我得到的错误（无值），或者无法获取json，因为代码不正确。

代码：

public class Task extends AsyncTask<String, Void, String>
{
    @Override
    protected String doInBackground(String... urls)
    {
        JSONObject json = getJSONFromUrl(URL);
        parseJson(json);
        return "Something";
    }
    @Override
    protected void onPostExecute(String result)
    {
    }
}

public JSONObject getJSONFromUrl(String url) {
    Log.v("INFO", "Requesting: " + url);
    JSONObject jObj = null;
    String json = null;

    // Making HTTP request
    StringBuffer chaine = new StringBuffer("");
    try {
        java.net.URL urlCon = new URL(url);
        HttpURLConnection connection = (HttpURLConnection) urlCon
                .openConnection();
        connection.setRequestProperty("User-Agent", "Universal/2.0 (Android)");
        connection.setRequestMethod("GET");
        connection.setDoInput(true);
        connection.connect();

        //InputStream inputStream;
        //if(connection.getResponseCode() >= HttpStatus.SC_BAD_REQUEST)
        //  inputStream = connection.getErrorStream();
        //else
        //  inputStream= connection.getInputStream();
        Log.v("INFO", "ResponseCode: " + connection.getResponseCode());

        InputStream inputStream = connection.getInputStream();

        BufferedReader rd = new BufferedReader(new InputStreamReader(
                inputStream));
        String line = "";
        while ((line = rd.readLine()) != null) {
            chaine.append(line);
        }

    } catch (IOException e) {
        // writing exception to log
        e.printStackTrace();
    }

    json = chaine.toString();

你可以帮忙吗？

你的问题在这一行：

public void parseJson(JSONObject json) {
    ...
    JSONObject post = (JSONObject) getJSONFromUrl(URL);
    ...
}

您必须使用JSONObject post = json.getJSONObject("post");
