WiFi设备MAC地址的获取-----服务器端

很简单，就是一个接收安卓端的信息，然后转存到数据库中

ServerForGetMethod：

package com.gm.servlet;

import java.net.HttpURLConnection;
import java.net.URL;
import java.net.URLEncoder;
import java.util.HashMap;
import java.util.Map;

import android.os.Handler;

public class SendDateToServer {
private static String url="http://10.18.55.240:8080/ServerForGetMethod/servlet/ServerForGetMethod";
public static final int SEND_SUCCESS=0x123;
public static final int SEND_FAIL=0x124;
private Handler handler;
public SendDateToServer(Handler handler){
this.handler=handler;
}

public void SendDataToServer(String macaddress){
final Map<String,String>map=new HashMap<String,String>();
map.put("macaddress", macaddress);
new Thread(new Runnable(){

public void run(){
try{
if(sendGetRequest(map,url,"utf-8")){
handler.sendEmptyMessage(SEND_SUCCESS);
}else{
handler.sendEmptyMessage(SEND_FAIL);
}
}catch(Exception e){
e.printStackTrace();
}
}
}).start();
}

private boolean sendGetRequest(Map<String,String> param,String url,String encoding) throws Exception{

StringBuffer sb=new StringBuffer(url);
if(!url.equals("")&!param.isEmpty()){
sb.append("?");
for(Map.Entry<String, String>entry:param.entrySet()){
sb.append(entry.getKey()+"=");
sb.append(URLEncoder.encode(entry.getValue(),encoding));
sb.append("&");
}
sb.deleteCharAt(sb.length()-1);
}
HttpURLConnection conn=(HttpURLConnection) new URL(sb.toString()).openConnection();
conn.setConnectTimeout(5000);
conn.setRequestMethod("GET");
if(conn.getResponseCode()==200){
return true;
}
return false;
}

}
