问题描述
我试图解析<一个href=\"http://gdata.youtube.com/feeds/api/playlists/2B3B8DDAE8F71C46?v%E2%80%8C%E2%80%8B=2&alt=json\"相对=nofollow>这个链接作为JSON，但总是得到错误不能转换成以JSONOject。
我已经试过样本数量，以字符串转换为JSONObject的，但其中任何一个没有运气。我不知道InputStream的大小是否少这么多的数据或没有。
HttpClient的客户端=新DefaultHttpClient（）;
//执行GET请求到YouTube为所有的一个JSON列表
//由特定用户视频 // URI uri_ =新的URI（https://gdata.youtube.com/feeds/api/playlists/2B3B8DDAE8F71C46?v = 2及ALT = JSON）;
HttpUriRequest要求=新HttpGet(\"https://gdata.youtube.com/feeds/api/playlists/2B3B8DDAE8F71C46?v%E2%80%8C%E2%80%8B=2&alt=json\");
//获取响应了YouTube发回
HTT presponse响应= client.execute（请求）;
//转换这种反应成可读的字符串
串jsonString = StreamUtils.convertToString（response.getEntity（）的getContent（））; 的System.out.println（JSON：+ jsonString）;
//创建我们可以从字符串使用JSON对象
JSONObject的JSON =新的JSONObject（jsonString）;
code到的InputStream转换成字符串;
的BufferedReader读者=新的BufferedReader（新的InputStreamReader（
InputStream的，ISO-8859-1），8）;
StringBuilder的SB =新的StringBuilder（）;
串线= NULL;
而（（行= reader.readLine（））！= NULL）{
sb.append（行+\\ n）;
}
inputStream.close（）;
输出字符串：

请帮我解决这个问题。

解决方案
我有2.3同样的问题，但在4.0它的罚款。
我整晚都在寻找解决方案。这是pretty简单 - 需要移除的字符串第一个符号，从URL接受
//转换这种反应成可读的字符串
串jsonString = StreamUtils.convertToString（response.getEntity（）的getContent（））;
jsonString = jsonString.substring（1）;
I am trying to parse this link as a JSON, but always getting the error Cannot converted into to JSONOject.
I have tried number of samples, to convert string to JSONObject, but no luck with any of them. I am not sure whether the size of Inputstream is less for this much data or not.
HttpClient client = new DefaultHttpClient();
// Perform a GET request to YouTube for a JSON list of all the
// videos by a specific user
//URI uri_ = new URI("https://gdata.youtube.com/feeds/api/playlists/2B3B8DDAE8F71C46?v=2&alt=json");
HttpUriRequest request = new HttpGet("https://gdata.youtube.com/feeds/api/playlists/2B3B8DDAE8F71C46?v%E2%80%8C%E2%80%8B=2&alt=json");
// Get the response that YouTube sends back
HttpResponse response = client.execute(request);
// Convert this response into a readable string
String jsonString = StreamUtils.convertToString(response.getEntity().getContent());
System.out.println("JSON:" + jsonString );
// Create a JSON object that we can use from the String
JSONObject json = new JSONObject(jsonString);
Code to convert inputstream into string;
BufferedReader reader = new BufferedReader(new InputStreamReader(
inputStream, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
inputStream.close();
Output string :

Please help me to resolve the issue.Thanks,Yuvi
解决方案
I have the same problem on 2.3, but on 4.0 it's fine.I was looking for solution all evening. It's pretty simple - need remove first symbol from string, that receive from url.
// Convert this response into a readable string
String jsonString = StreamUtils.convertToString(response.getEntity().getContent());
jsonString = jsonString.substring(1);
