求一段android平台下的Get网页数据的代码

Question

我想得到这个网页的文件的内容。
http://weather.gtimg.cn/city/0101021403.js,
试了好多方法，返回的都是乱码或者空/谁能帮我
 这个是qq获得天气情况的代码。
 我以前代码是
public static String geturlget(String turl, String encode)
                         throws IOException {
                 URL url = new URL(turl);
                 HttpURLConnection conn = (HttpURLConnection) url.openConnection();
                 conn.setRequestMethod("GET");
                 conn.setConnectTimeout(5 * 1000);                 InputStream input = conn.getInputStream();
                 InputStreamReader inputReader = new InputStreamReader(input, "gbk");//gbk改成utf-8或者不写，都是乱码
                BufferedReader reader = new BufferedReader(inputReader);                 String inputLine = null;                 StringBuffer sb = new StringBuffer();
                 while ((inputLine = reader.readLine()) != null) {
                         sb.append(inputLine);
                 }
                 reader.close();
                 inputReader.close();
                 input.close();
                 conn.disconnect();
                 return sb.toString();
         }

public void getJsonDataFromServer(String urlPath, String Args, String cmd) throws Exception{
    
     StringBuffer json=new StringBuffer();
    URL url = null;
    HttpsURLConnection urlCon = null;
    BufferedReader in = null;
   
     if(cmd.equals("POST")){
            url = new URL(urlPath);
            urlCon = (HttpsURLConnection) url.openConnection();
            urlCon.setReadTimeout(20000);
               urlCon.setConnectTimeout(5000);
               urlCon.setDoOutput(true);
               urlCon.setDoInput(true);
               urlCon.setRequestMethod("POST");
               urlCon.setUseCaches(false);
               DataOutputStream osw = new DataOutputStream(urlCon.getOutputStream());
               osw.writeBytes(Args);
               osw.flush();
               osw.close();
     }
     else if(cmd.equals("GET"))
     {
    
            url = new URL(urlPath);
            urlCon = (HttpsURLConnection) url.openConnection();
            urlCon.setReadTimeout(20000);
               urlCon.setConnectTimeout(5000);
               urlCon.setDoOutput(true);
               urlCon.setDoInput(true);
     }
             
     int ReCode = 0;        
     ReCode = urlCon.getResponseCode();
//           Log.i(TAG, " getJsonData():urlCon.getResponseCode()================"+ ReCode);
           if(ReCode!=200){
             in = new BufferedReader(new InputStreamReader(urlCon.getErrorStream(),"UTF-8"));
            }else{
             in = new BufferedReader(new InputStreamReader(urlCon.getInputStream(),"UTF-8"));
            }
           String line;
           while((line = in.readLine()) != null) {
               json.append(line);
           }        if(null != urlCon){
         urlCon.disconnect();
         urlCon = null;
        }
       in.close();
}你试试，参数你自己可以看着填

public static String get(String turl, String encode) throws IOException { StringBuffer json = new StringBuffer();
URL url = new URL(turl);
HttpsURLConnection urlCon = (HttpsURLConnection) url.openConnection();/////////执行到此句，报错
BufferedReader in = null; urlCon.setReadTimeout(20000);
urlCon.setConnectTimeout(5000);
urlCon.setDoOutput(true);
urlCon.setDoInput(true); int ReCode = 0;
ReCode = urlCon.getResponseCode();
if (ReCode != 200) {
in = new BufferedReader(new InputStreamReader(
urlCon.getErrorStream(), "UTF-8"));
} else {
in = new BufferedReader(new InputStreamReader(
urlCon.getInputStream(), "UTF-8"));
}
String line;
while ((line = in.readLine()) != null) {
json.append(line);
} if (null != urlCon) {
urlCon.disconnect();
urlCon = null;
}
in.close();
return json.toString(); }
