如何解析JSONP(带填充的JSON)响应?

我这样做很困惑。我要做的是,解析来自服务器的JSONP响应并显示它。是否可以解析Android中的JSONP响应?

以下是我的回复:

{
    "Reference1":"String content",
    "Reference2":"String content",
    "Reference3":"String content",
    "Reference4":"String content"

}

谢谢

填充本身绝不是问题。每个体面的JSON解析库都将以transperantly的方式处理它。我个人非常乐意使用GSON库。我在很多项目中都使用过它,从来没有发现过要抱怨的事情。

PS:也许我误解了你,但是当你说解析时,我假设你需要获取属性的值而不需要保留任何填充,对吗?

我认为这个tutorial非常详细解析android.Hope中的json这对你有帮助。

我在许多项目中所做的是首先使用以下代码将从http流读取的字符串转换为JSONObject:

JSONObject jsonOBJ=new JSONObject(jsonString);

然后使用jsonobject.getString("tag")读取每个标记。对于你的代码,它类似于:

String reference1=jsonobject.getString("Reference1");

现在referece1 = String content

的值

这是我的http获取代码:

String url="Your URL Goes Here";
DefaultHttpClient httpclient = new DefaultHttpClient();
HttpGet httpget = new HttpGet(url);
HttpResponse response;
try {
    try 
    {
      InetAddress i = InetAddress.getByName(url);
    } catch (UnknownHostException e1) {
      e1.printStackTrace();
    }
    response = httpclient.execute(httpget);
    HttpEntity entity = response.getEntity();
    if (entity != null) {
        InputStream instream = entity.getContent();
        String result= convertStreamToString(instream);
        stringContent=new StringContent(result);
        instream.close();
    }
} catch (ClientProtocolException e) {
    e.printStackTrace();
} catch (IOException e) {
    e.printStackTrace();
}

以下是convertStreamToString

private static String convertStreamToString(InputStream is) 
{
    /*
     * To convert the InputStream to String we use the BufferedReader.readLine()
     * method. We iterate until the BufferedReader return null which means
     * there's no more data to read. Each line will appended to a StringBuilder
     * and returned as String.
     */
        BufferedReader reader = new BufferedReader(new InputStreamReader(is));
        StringBuilder sb = new StringBuilder();

        String line = null;
        try {
            while ((line = reader.readLine()) != null) {
                sb.append(line + "\n");
        }
    } catch (IOException e) {
        e.printStackTrace();
    } finally {
        try {
            is.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    return sb.toString();
}
