本文原理：將資料拼接在訪問的伺服器地址後面，形式如下

http://192.168.1.100:8080/web_login/login?number=123&pwd=123

其中number和pwd是要上傳的資料，然後設定請求方式為GET,訪問伺服器後拿到伺服器返回結果。最後handler更新UI

new Thread(){

public void run() {

try {
path = path+"number="+URLEncoder.encode(number, "UTF-8")+"&pwd="+URLEncoder.encode(pwd, "UTF-8");
System.out.println(path);
URL url = new URL(path);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
//設定請求方式為get
conn.setRequestMethod("GET");
conn.setConnectTimeout(5000);

int code = conn.getResponseCode();

if(code==200){

InputStream in = conn.getInputStream();

String data = StreamTool.decodeStream(in);

Message msg = Message.obtain();
msg.what=SUCCESS;
msg.obj = data;
mHandler.sendMessage(msg);
}

} catch (Exception e) {
e.printStackTrace();
Message msg = Message.obtain();
msg.what=ERROR;
mHandler.sendMessage(msg);
}

};

}.start();

  伺服器端解決以get方式提交的亂碼：方式如下：

  原理：用什麼方式編碼就用什麼方式解碼，這樣才不會亂碼
