将GBK编码形式的xml文件 数据请求转为utf-8

[java] view
plain copy

public String resposeString(String urlStr){  

  

        String result = "";  

        try  

        {  

            URL url = new URL(urlStr);  

  

            HttpURLConnection httpURLConnection = null;  

  

            httpURLConnection = (HttpURLConnection)url.openConnection();  

  

            httpURLConnection.setRequestMethod("POST");  

  

            httpURLConnection.setDoOutput(true);//上传数据  

            httpURLConnection.setConnectTimeout(15000);  

            httpURLConnection.setReadTimeout(15000);  

            InputStream inputStream = httpURLConnection.getInputStream();//获取返回的数据流  

  

            InputStreamReader isr = new InputStreamReader(inputStream, "gbk");//一定要在这个地方才不会乱码(utf-8,gb2312)  

  

            BufferedReader br = new BufferedReader(isr);//利用BufferedReader将流转为String  

  

            String temp;  

  

            while((temp = br.readLine()) != null)  

            {  

                result = result + temp;

        catch (MalformedURLException e)  

        {  

            e.printStackTrace();  

        }   

        catch (IOException e)   

        {  

            e.printStackTrace();  

        }   

        return result;
