Android HttpURLConnection Post 参数 （https）

声明utf－8:

 public static String CHARSET_UTF8 = HTTP.UTF_8;

eg：登陆请求方法，通过接口返回结果：

 public static void login(String username, String password, ResponseCallbackHandler responseCallbackHandler) {
         Map<String, String> params = new HashMap<>();
         params.put("username", username);
         params.put("password", password);
         post("https:/..../login", params, responseCallbackHandler);
     }

post请求执行前，网络判断，以及url参数转换：

 private static void post(final String url, Map<String, String> _params, final ResponseCallbackHandler responseCallbackHandler) {

         if (!NetworkUtils.isNetworkConnected(RunnerApp.getContext())) {
             if (responseCallbackHandler != null) {
                 responseCallbackHandler.onNetworkError();
                 responseCallbackHandler.onFinish();
             }
             return;
         }
         final String params = map2Url(_params);
         new Thread(new Runnable() {
             @Override
             public void run() {
                 post(url, params, responseCallbackHandler);
             }
         }).start();
     }

map转换成string类型的url参数：

 /**
      * map转url参数
      */
     public static String map2Url(Map<String, String> paramToMap) {
         if (null == paramToMap || paramToMap.isEmpty()) {
             return null;
         }
         StringBuffer url    = new StringBuffer();
         boolean      isfist = true;
         for (Map.Entry<String, String> entry : paramToMap.entrySet()) {
             if (isfist) {
                 isfist = false;
             } else {
                 url.append("&");
             }
             url.append(entry.getKey()).append("=");
             String value = entry.getValue();
             if (!TextUtils.isEmpty(value)) {
                 try {
                     url.append(URLEncoder.encode(value, CHARSET_UTF8));
                 } catch (UnsupportedEncodingException e) {
                     e.printStackTrace();
                 }
             }
         }
         return url.toString();
     }

post执行：(注：这里简单的描述了下接口返回参数而已)。

 /**
      * post请求
      */
     public static void post(String url, String params, ResponseCallbackHandler responseCallbackHandler) {
         StringBuffer bufferRes = null;
         try {
             HttpURLConnection http = initHttps(url, "POST", null);
             OutputStream out = http.getOutputStream();
             out.write(params.getBytes(CHARSET_UTF8));
             out.flush();
             out.close();

             InputStream in = http.getInputStream();
             BufferedReader read = new BufferedReader(new InputStreamReader(in, CHARSET_UTF8));
             String valueString = null;
             bufferRes = new StringBuffer();
             while ((valueString = read.readLine()) != null) {
                 bufferRes.append(valueString);
             }
             in.close();
             if (http != null) {
                 http.disconnect();// 关闭连接
             }
             if(responseCallbackHandler != null) {
                 responseCallbackHandler.onSuccess(bufferRes.toString());
                 LogUtils.d(tag, "onSuccess");
                 LogUtils.d(tag, "onSuccess:" + bufferRes.toString());
             }
         } catch (Exception e) {
             e.printStackTrace();
             if (responseCallbackHandler != null) {
                 responseCallbackHandler.onNetworkError();
             }
         }
         if (responseCallbackHandler != null) {
             responseCallbackHandler.onFinish();
         }
     }

实例化HttpURLConnection post请求时，ssl添加权限：

 /**
      * 初始化http请求参数
      */
     private static HttpsURLConnection initHttps(String url, String method, Map<String, String> headers)
             throws IOException, NoSuchAlgorithmException, NoSuchProviderException, KeyManagementException {
         TrustManager[] tm = {new CustomX509TrustManager()};
         SSLContext     sslContext = SSLContext.getInstance("TLSv1");
         sslContext.init(null, tm, new java.security.SecureRandom());
         // 从上述SSLContext对象中得到SSLSocketFactory对象
         SSLSocketFactory ssf  = sslContext.getSocketFactory();
         URL              _url = new URL(url);
         HttpsURLConnection http = (HttpsURLConnection) _url.openConnection();
         // 连接超时
         http.setConnectTimeout(25000);
         // 读取超时 --服务器响应比较慢，增大时间
         http.setReadTimeout(25000);
         http.setRequestMethod(method);
         http.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
         http.setRequestProperty("User-Agent",
                 "Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/33.0.1750.146 Safari/537.36");
         if (null != headers && !headers.isEmpty()) {
             for (Map.Entry<String, String> entry : headers.entrySet()) {
                 http.setRequestProperty(entry.getKey(), entry.getValue());
             }
         }
         http.setSSLSocketFactory(ssf);
         http.setDoOutput(true);
         http.setDoInput(true);
         http.connect();
         return http;
     }

添加证书管理：

 // 证书管理
 class CustomX509TrustManager implements X509TrustManager {

     public X509Certificate[] getAcceptedIssuers() {
         return null;
     }

     @Override
     public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
     }

     @Override
     public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
     }
 }

参考：

Javax.net.ssl.SSLHandshakeException: javax.net.ssl.SSLProtocolException: SSL handshake aborted: Failure in SSL library, usually a protocol error
