ApachehttpClient是谷歌官方的http請求，Eclipse自帶有，但是AS好像沒有（還是我的AS版本問題）。它比httpURLConnection請求更簡單。
post請求相對get就是引數有變化

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    private
 
 void getResult() {
        new Thread(new Runnable() {

            @Override
            public void run() {
                String spec = "http://187.1.1.1:8080/";
                try {
                    // 建立請求物件
                    HttpGet get = new HttpGet(spec);
                    // 建立Http客戶端物件
                    HttpClient client = new
 
 DefaultHttpClient();// 介面不能new
                    // 向伺服器傳送請求並返回相應物件
                    HttpResponse execute = client.execute(get);// 請求的方式
                    // 獲取返回的狀態碼
                    int code = execute.getStatusLine().getStatusCode();
                    switch (code) {
                    case HttpStatus.SC_OK:
                        // 200
 

                        HttpEntity entity = execute.getEntity();// 獲取實體
                        String result = EntityUtils.toString(entity);// 將實體通過實體工具轉成string
                        break;
                    case HttpStatus.SC_NOT_FOUND:
                        // 404
                        break;
