Android HttpURLConnection Post 参数（https）

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<String, String> 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<String, String> _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             @Override
13             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<String, String> paramToMap) {
 5         if (null == paramToMap || paramToMap.isEmpty()) {
 6             return null;
 7         }
 8         StringBuffer url    = new StringBuffer();
 9         boolean      isfist = true;
10         for (Map.Entry<String, String> 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<String, String> 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<String, String> 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     @Override
13     public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
14     }
15 }
