Android - 解析JSON失败
问题描述:
我有一个JSON表,我试图解析一个URL。它始于节点{所以我解析为JSONObject。但我发现了以下错误:Android - 解析JSON失败
11-21 02:33:38.660: E/JSON Parser(20307): Error parsing data org.json.JSONException: Expected ':' after n at character 7 of {n "videos": [n {n "title": "Big Buck Bunny",n "thumbnail": "http://camendesign.com/code/video_for_everybody/poster.jpg",n "video_url": "http://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4"n },n {n "title": "Perfect Lamborghini Impression",n "thumbnail": "http://www.mp4point.com/images/thumb/perfect-lamborghini-impression.jpg",n "video_url": "http://www.mp4point.com/downloads/7b0de690da55.mp4"n },n {n "title": "Flute Beatboxing",n "thumbnail": "http://www.mp4point.com/images/thumb/flute-beatboxing.jpg",n "video_url": "http://www.mp4point.com/downloads/bd8bda782093.mp4"n }n ]n}n
我使用下面的代码来解析:
public class JSONParser {
static InputStream is = null;
static JSONObject jObj = null;
static String json = "";
public JSONParser(){
}
public JSONObject getJSONfromURL(String url){
try {
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) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
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;
}
}
任何想法可能会导致此问题?这真的很令人沮丧,我现在试图在这里发现3个小时的错误。这是我向前推进App的唯一一步。感谢任何帮助。

答
你的代码读取响应在每行的端部插入的外来字符 'n':
while ((line = reader.readLine()) != null) {
sb.append(line + "n");
}
尝试改变到
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}

我不确定JSON是否错误。我已经检查过它的语法10次了。 – rencsaridogan 2014-11-21 01:16:30
