doGet方法中，为什么使用了 URLEncoder.encode(name,"utf-8")进行中文转码但在手机客户端输入中文，在控制台上任然是乱码？

private void doGet(){

try {

//中文字符转码 URLEncoder.encode(name,"utf-8")

url=url+"?name="+URLEncoder.encode(name,"utf-8")+"&age="+age;

} catch (UnsupportedEncodingException e1) {

// TODO Auto-generated catch block

e1.printStackTrace();

}

try {

URL httpUrl=new URL(url);

HttpURLConnection conn=(HttpURLConnection) httpUrl.openConnection();

conn.setRequestMethod("GET");

conn.setReadTimeout(5000);

BufferedReader reader=new BufferedReader(new InputStreamReader(conn.getInputStream()));

String str;

StringBuffer sb=new StringBuffer();

while ((str=reader.readLine())!=null) {

sb.append(str);

}
