HttpUrlConnection的get請求和post請求

的簡單標準請求方式

以後方便使用

---GET---

//        HashMap<String, Object> params = new HashMap<>();
//        params.put("name", "abc");
//        params.put("age", "123");
//        String baseUrl = UrlUtil.appendUrl("http://japi.juhe.cn/qqevaluate/qq", params);
//
//        HttpURLConnection connection = null;
//
//        try {
//            URL url = new URL(baseUrl);
//            connection = (HttpURLConnection) url.openConnection();
//            connection.setRequestMethod("GET");
//            connection.setConnectTimeout(5000);
//            connection.setReadTimeout(5000);
//            connection.connect();
//
//            String response = StreamUtil.getStringFromStream(connection.getInputStream());
//            String result = response;
//
//        } catch (Exception e) {
//            e.printStackTrace();
//        } finally {
//            if (connection != null) {
//                connection.disconnect();
//            }
//        }
 

---POST---

//        HashMap<String, String> params = new HashMap<>();
//        params.put("name", "abc");
//        params.put("age", "123");
//        String param = MapUtil.getStringFromMap(params);
//
//        HttpURLConnection connection = null;
//
//        try {
//            URL url = new URL("http://japi.juhe.cn/qqevaluate/qq");
//            connection = (HttpURLConnection) url.openConnection();
//            connection.setRequestMethod("POST");
//            connection.setConnectTimeout(5000);
//            connection.setReadTimeout(5000);
//
//            connection.connect();
//
//            PrintWriter writer = new PrintWriter(connection.getOutputStream());
//            writer.write(param);
//            writer.flush();
//            writer.close();
//
//            String response = StreamUtil.getStringFromStream(connection.getInputStream());
//
//        } catch (Exception e) {
//            e.printStackTrace();
//        } finally {
//            if (connection != null) {
//                connection.disconnect();
//            }
//        }
 

另外post引數拼接後寫入流

//public class MapUtil {
//
//    public static String getStringFromMap(Map<String, String> map) {
//        String string = "";
//        Iterator<Map.Entry<String, String>> iterator = map.entrySet().iterator();
//        while (iterator.hasNext()) {
//            Map.Entry<String, String> entry = iterator.next();
//            string = string + entry.getKey() + "=" + entry.getValue();
//            if (iterator.hasNext()) {
//                string = string + "&";
//            }
//        }
//        return string;
//    }
//
//}
