HttpURLConnection 分別有GET和POST請求
Post方式的

 1     public void testPOstbendi() throws Exception { 2         //構建伺服器位址 3         URL url = new URL("http://192.168.40.194/qiantai/admin/login_check.php"); 4         //擷取HttpURLConnection對象 5         HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection(); 6         //佈建要求時間 7         httpURLConnection.setReadTimeout(10000); 8         httpURLConnection.setConnectTimeout(10000); 9         //設定方式10         httpURLConnection.setRequestMethod("POST");11         //建立一個實際的連結12         httpURLConnection.connect();13         //擷取輸出資料流14         OutputStream os = httpURLConnection.getOutputStream();15         //POST提交的欄位16         String message ="username=admin&userpass=123456";17         //想伺服器寫入資料18         os.write(message.getBytes());19         //擷取服務端返回的狀態代碼20         int code = httpURLConnection.getResponseCode();21         //switch判斷一下22         switch (code){23             case 201:24             case 200:25                 //擷取伺服器返回的輸入資料流26                 InputStream inputStream = httpURLConnection.getInputStream();27                 StringBuffer stringBuffer = new StringBuffer();28                 String strings;29                 //轉換成字元輸入資料流30                 BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream));31                 while ((strings = bufferedReader.readLine())!= null){32                     stringBuffer.append(strings);33                 }34                 //關閉資料連結35                 httpURLConnection.disconnect();36                 Log.e(TAG, "testURl: "+stringBuffer.toString());37                 break;38             case 401:39                 Log.e(TAG, "tes401了啊==========================================================");40                 break;41         }42     }

GET方式的

    public void testURl() throws Exception {        //構建URL        URL url = new URL("http://life.tenpay.com/cgi-bin/mobile/MobileQueryAttribution.cgi?chgmobile=15850781443");        //擷取httpURLConnection        HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();        //設定超市時間        httpURLConnection.setConnectTimeout(10000);        httpURLConnection.setReadTimeout(10000);        //佈建要求方式        httpURLConnection.setRequestMethod("GET");        //擷取請求碼        int code = httpURLConnection.getResponseCode();        switch (code){            case 200:                InputStream inputStream = httpURLConnection.getInputStream();                StringBuffer sb = new StringBuffer();                String str;                BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));                while ((str = reader.readLine()) != null){                    sb.append(str+"\n");                }                Log.e(TAG, "testURl: "+sb.toString());                break;            case 401:                Log.e(TAG, "testURl: 401");                break;        }    }
