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 }
