声明utf－8:

1 public static String CHARSET_UTF8 = HTTP.UTF_8;

eg：登陆请求方法，通过接口返回结果：

1 public static void login(String username, String password, ResponseCallbackHandler responseCallbackHandler) {2         Map
     
       params = new HashMap<>();3         params.put("username", username);4         params.put("password", password);5         post("https:/..../login", params, responseCallbackHandler);6     }
     

post请求执行前，网络判断，以及url参数转换：

1 private static void post(final String url, Map
     
       _params, final ResponseCallbackHandler responseCallbackHandler) { 2  3         if (!NetworkUtils.isNetworkConnected(RunnerApp.getContext())) { 4             if (responseCallbackHandler != null) { 5                 responseCallbackHandler.onNetworkError(); 6                 responseCallbackHandler.onFinish(); 7             } 8             return; 9         }10         final String params = map2Url(_params);11         new Thread(new Runnable() {12             @Override13             public void run() {14                 post(url, params, responseCallbackHandler);15             }16         }).start();17     }
     

map转换成string类型的url参数：

1 /** 2      * map转url参数 3      */ 4     public static String map2Url(Map
     
       paramToMap) { 5         if (null == paramToMap || paramToMap.isEmpty()) { 6             return null; 7         } 8         StringBuffer url    = new StringBuffer(); 9         boolean      isfist = true;10         for (Map.Entry
      
        entry : paramToMap.entrySet()) {11             if (isfist) {12                 isfist = false;13             } else {14                 url.append("&");15             }16             url.append(entry.getKey()).append("=");17             String value = entry.getValue();18             if (!TextUtils.isEmpty(value)) {19                 try {20                     url.append(URLEncoder.encode(value, CHARSET_UTF8));21                 } catch (UnsupportedEncodingException e) {22                     e.printStackTrace();23                 }24             }25         }26         return url.toString();27     }
      
     

post执行：(注：这里简单的描述了下接口返回参数而已)。

1 /** 2      * post请求 3      */ 4     public static void post(String url, String params, ResponseCallbackHandler responseCallbackHandler) { 5         StringBuffer bufferRes = null; 6         try { 7             HttpURLConnection http = initHttps(url, "POST", null); 8             OutputStream out = http.getOutputStream(); 9             out.write(params.getBytes(CHARSET_UTF8));10             out.flush();11             out.close();12 13             InputStream in = http.getInputStream();14             BufferedReader read = new BufferedReader(new InputStreamReader(in, CHARSET_UTF8));15             String valueString = null;16             bufferRes = new StringBuffer();17             while ((valueString = read.readLine()) != null) {18                 bufferRes.append(valueString);19             }20             in.close();21             if (http != null) {22                 http.disconnect();// 关闭连接23             }24             if(responseCallbackHandler != null) {25                 responseCallbackHandler.onSuccess(bufferRes.toString());26                 LogUtils.d(tag, "onSuccess");27                 LogUtils.d(tag, "onSuccess:" + bufferRes.toString());28             }29         } catch (Exception e) {30             e.printStackTrace();31             if (responseCallbackHandler != null) {32                 responseCallbackHandler.onNetworkError();33             }34         }35         if (responseCallbackHandler != null) {36             responseCallbackHandler.onFinish();37         }38     }

实例化HttpURLConnection post请求时，ssl添加权限：

1 /** 2      * 初始化http请求参数 3      */ 4     private static HttpsURLConnection initHttps(String url, String method, Map
     
       headers) 5             throws IOException, NoSuchAlgorithmException, NoSuchProviderException, KeyManagementException { 6         TrustManager[] tm = {
   new CustomX509TrustManager()}; 7         SSLContext     sslContext = SSLContext.getInstance("TLSv1"); 8         sslContext.init(null, tm, new java.security.SecureRandom()); 9         // 从上述SSLContext对象中得到SSLSocketFactory对象10         SSLSocketFactory ssf  = sslContext.getSocketFactory();11         URL              _url = new URL(url);12         HttpsURLConnection http = (HttpsURLConnection) _url.openConnection();13         // 连接超时14         http.setConnectTimeout(25000);15         // 读取超时 --服务器响应比较慢，增大时间16         http.setReadTimeout(25000);17         http.setRequestMethod(method);18         http.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");19         http.setRequestProperty("User-Agent",20                 "Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/33.0.1750.146 Safari/537.36");21         if (null != headers && !headers.isEmpty()) {22             for (Map.Entry
      
        entry : headers.entrySet()) {23                 http.setRequestProperty(entry.getKey(), entry.getValue());24             }25         }26         http.setSSLSocketFactory(ssf);27         http.setDoOutput(true);28         http.setDoInput(true);29         http.connect();30         return http;31     }
      
     

添加证书管理：

1 // 证书管理 2 class CustomX509TrustManager implements X509TrustManager { 3  4     public X509Certificate[] getAcceptedIssuers() { 5         return null; 6     } 7  8     @Override 9     public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {10     }11 12     @Override13     public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {14     }15 }
