摘要：
/***
* 封裝了post請求的方法：
* 1.使用了異步AsyncTask + Handler的處理模式；
* 2.適用於僅僅一條數據的請求，最大的優勢在於:能夠同時適用於多條數據的請求，並保證數據不出現紊亂；
* 3.這裏面也同時使用了
* compile 'com.jakewharton:butterknife:7.0.0'
* compile 'com.kaopiz:kprogresshud:1.0.1'
* 對於這2個三方的類，
* 雖然kprogresshud有些不足，（kprogresshud--缺點是在進度框顯示的過程中不能手動點擊取消，只能返回取消）
* 但是butterknife真是太方便開發了，也有不少人已經介紹了，在此就不多做介紹 （butterknife--引用佈局控件非常方便）
* 4.封裝了log打印的類-L.class;
* 初始化的讓其顯示log方法 L.isDebug = true;默認不打印log
* 5.此處的接口都是使用的三方接口：知乎地址：https://www.zhihu.com/question/39479153(未使用)
* 此處可以將自己的ip接口放上去。
*
* 說明：我的qq號：1457521527；歡迎互相學習~

代碼摘抄：
一）主類：
public class MainActivity extends AppCompatActivity { Handler mHandler = new Handler(){ @Override public void handleMessage(Message msg) { super.handleMessage(msg); String msgResult = (String) msg.obj; L.i("--handler處理--" + msg.what + "=====" + msgResult); switch (msg.what){ case 1: L.i("--1--"+msgResult); break;
......
} } }; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); getSupportActionBar().hide(); setContentView(R.layout.activity_main); ButterKnife.bind(this); L.isDebug = true; intRequsetData(); findViewById(R.id.requst_button).setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { intRequsetData(); } }); } private void intRequsetData() { requestData1(); requestData2(); requestData3(); requestData4(); requestData5(); requestData3(); } private void requestData1() { String methodName0 = Constants.httpIp_aa; String[][] stringArr = new String[][]{{"" + 1,methodName0,0+""} ,{"json", "ok"}}; new SimpleAsyRequestUtil(MainActivity.this, R.string.test_pd_running1,mHandler); new SimpleAsyRequestUtil.fileUploadTask().execute(stringArr, null, null); }
......}
能實現請求的對話框加載等異步操作：
二）異步處理類
/** * 異步處理 * Created by yjbo on 2016/5/25. * */ public class SimpleAsyRequestUtil { static Activity mactivity; private static KProgressHUD hud; static int mshowInt =0 ; static Handler mhandler; public static void scheduleDismiss() { if (hud != null) { hud.dismiss(); } } public SimpleAsyRequestUtil(Activity activity,int showInt,Handler handler) { L.i("初始化"+showInt); mshowInt = showInt; this.mactivity = activity; mhandler = handler; } public static class fileUploadTask extends AsyncTask<String[][], String, String[]> { @Override protected String[] doInBackground(String[][]... params) { if (!CommonUtil.checkNet(mactivity)) {//無網絡則提示 return new String[]{Integer.valueOf(params[0][0][0] + "")+"","沒有網絡"}; }
Map<String, Object> requestParamsMap0 = new HashMap<String, Object>(); try { for (int i =0;i < params[0].length-1;i++) { requestParamsMap0.put(params[0][i + 1][0], params[0][i + 1][1]); } }catch (Exception ex){ ex.printStackTrace(); } String[] strResult = new String[]{};
strResult = SimpleHttpUrlConnUtil.post(mactivity, params[0][0][1] + "", requestParamsMap0, Integer.valueOf(params[0][0][0] + "")); return strResult; } @Override protected void onPreExecute() { int showInt = mshowInt; String showStr = ""; if (showInt == 0) { showStr = ""; } else if (showInt == 1){ showStr = mactivity.getResources().getString(R.string.pd_running); }else{ showStr = mactivity.getResources().getString(showInt); } if (!CommonUtil.isNull(showStr)) { scheduleDismiss(); hud = KProgressHUD.create(mactivity) .setStyle(KProgressHUD.Style.SPIN_INDETERMINATE) .setLabel(showStr) .setCancellable(true); hud.show(); } } @Override protected void onProgressUpdate(String... values) { super.onProgressUpdate(values); } @Override protected void onPostExecute(String[] result) { scheduleDismiss(); L.i("AsyRequestNewUtil-獲取訪問的數據" + result[0] + "---" + result[1]); Message msg = new Message(); msg.what = Integer.valueOf(result[0]); msg.obj = result[1]; mhandler.sendMessage(msg); } } }
三）http請求
/** * 數據請求的方法類 * Created by yjbo on 2016/5/13. */ public class SimpleHttpUrlConnUtil { public static String[] post(Activity mcontext, String methodName, Map<String, Object> requestParamsMap, int tag) { L.i("初始化"+methodName); String requestUrl = methodName;//urlCom+ BufferedReader bufferedReader = null; StringBuffer responseResult = new StringBuffer(); StringBuffer params = new StringBuffer(); HttpURLConnection httpURLConnection = null; Iterator it = requestParamsMap.entrySet().iterator(); while (it.hasNext()) { Map.Entry element = (Map.Entry) it.next(); try { params.append(URLEncoder.encode(element.getKey() + "", "UTF-8")); } catch (UnsupportedEncodingException e) { e.printStackTrace(); break; } params.append("="); try { params.append(URLEncoder.encode(element.getValue() + "", "UTF-8")); } catch (UnsupportedEncodingException e) { e.printStackTrace(); break; } params.append("&"); } if (params.length() > 0) { params.deleteCharAt(params.length() - 1); } try { URL realUrl = new URL(requestUrl); L.i("HttpUrlConnnewUtil請求的url" + requestUrl + "==" + tag); httpURLConnection = (HttpURLConnection) realUrl.openConnection(); httpURLConnection.setRequestMethod("POST"); httpURLConnection.setRequestProperty("accept", "*/*"); httpURLConnection.setRequestProperty("connection", "Keep-Alive"); httpURLConnection.setRequestProperty("Content-Length", String .valueOf(params.length())); httpURLConnection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); httpURLConnection.setRequestProperty("Connection", "Keep-Alive"); httpURLConnection.setRequestProperty("Charset", "UTF-8"); httpURLConnection.setDoOutput(true); httpURLConnection.setDoInput(true); httpURLConnection.setConnectTimeout(5000);//設置連接主機超時（單位：毫秒） httpURLConnection.setReadTimeout(5000);//設置從主機讀取數據超時（單位：毫秒） byte[] bypes = params.toString().getBytes(); httpURLConnection.getOutputStream().write(bypes); int responseCode = httpURLConnection.getResponseCode(); if (responseCode != 200) { L.i(mcontext.getResources().getString(R.string.service_back_error) + responseCode + "==" + tag); } else {//連接成功 bufferedReader = new BufferedReader(new InputStreamReader( httpURLConnection.getInputStream())); String line; while ((line = bufferedReader.readLine()) != null) { responseResult.append("/n").append(line); } } } catch (Exception e) { e.printStackTrace(); } finally {
httpURLConnection.disconnect(); try { if (bufferedReader != null) { bufferedReader.close(); } } catch (IOException ex) { ex.printStackTrace(); } String result2 = responseResult.toString(); L.i("HttpUrlConnnewUtil運行了finally" + result2 + "==" + tag); if (result2.contains("{") && result2.contains("}")) { int indexOfFirst = result2.indexOf("{"); int indexOfEnd = result2.lastIndexOf("}"); String strResult1 = "" + result2.substring(indexOfFirst, indexOfEnd + 1); if ("10025".equals(CommonUtil.getResult(strResult1, "error"))) { Intent mintent = new Intent(mcontext, MainActivity.class); mcontext.startActivity(mintent); } else { return new String[]{tag + "", strResult1}; } } else { L.i("沒有取到數據，-----"); return new String[]{tag + "", "沒有取到數據"}; } }
return new String[]{tag+"","httpConntion請求結束"};
}
