从URL获取JSON字符串转成JSONObject

private static JSONObject getObjectFromUrl(String s) throws IOException{
StringBuffer buffer = new StringBuffer();
// 通过js的执行路径获取后台数据进行解析
URL url = new URL(s);
HttpURLConnection http = (HttpURLConnection) url.openConnection();
http.setDoOutput(true);
http.setDoInput(true);
http.setUseCaches(false);
http.setRequestMethod("GET");
http.connect();
// 将返回的输入流转换成字符串
InputStream inputStream = http.getInputStream();
InputStreamReader inputStreamReader = new InputStreamReader(inputStream, "utf-8");
BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
String str = null;
while ((str = bufferedReader.readLine()) != null) {
buffer.append(str);
}
bufferedReader.close();
inputStreamReader.close();
// 释放资源
inputStream.close();
inputStream = null;
http.disconnect();
str = buffer.toString();
int index = str.indexOf("(");
String jsonString = str.substring(index + 1, str.length() -1);
JSONObject jo = JSONObject.fromObject(jsonString);
return jo;
}
public static void main(String[] args) throws IOException {
JSONObject jo=getObjectFromUrl("URL");
//当前页文章数组
JSONArray jsonArray = JSONArray.fromObject(jo.get("list"));
int arrlength=jsonArray.size();
for(int j=0;j<arrlength;j++){
JSONObject a = jsonArray.getJSONObject(j);
}
}
