我面临一个让我发疯的问题，我在这个网站和谷歌中搜索，但找不到任何结果。
我正在使用使用 JSON 解析器的 android sdk 构建一个应用程序。
我编写了处理 http 帖子的代码，我得到了正确的响应，但是当我尝试使用以下方法将其解析为 JSONObject 时：
strJson -> 来自服务器的响应。
JSONobject json = 新 JSONObject(strJson)
它没有解析所有数据并且一些对象是空白的（空指针）
我使用许多工具（包括 jsonlint.com）检查了 json 响应及其有效
问题是什么？
顺便说一句，这是 json 响应：

顺便说一句 2：
iOS 应用程序似乎可以正确解析它。
提前致谢。
编辑：
我得到响应的代码是：
public JSONObject getJSONFromURL(String URL,List<NameValuePair> params){
//try to make http request:
try{
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(URL+listToString(params));
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
}
catch(UnsupportedEncodingException e){
e.printStackTrace();
}
catch(ClientProtocolException e){
e.printStackTrace();
}
catch(IOException e){
e.printStackTrace();
}
//try to read the respond:
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();
strJson = sb.toString();
Log.e("JSON",strJson);
}
catch(Exception e){
Log.e("Buffer Error","Error converting result " + e.toString());
}
//try to parse the string to JSON object:
try{
json = new JSONObject(strJson);
}
catch(JSONException e){
Log.e("JSON Parser","Error parsing data " + e.toString());
}
return json;
}
json 返回的 json 对象缺少一些对象，如用户配置文件、成功等...
但 strJson 是有效的！
