使用Https发送请求

重写X509TrustManager

private static TrustManager myX509TrustManager = new X509TrustManager() {     @Override     public X509Certificate[] getAcceptedIssuers() {         return null;     }     @Override     public void checkServerTrusted(X509Certificate[] chain, String authType)     throws CertificateException {     }     @Override     public void checkClientTrusted(X509Certificate[] chain, String authType)     throws CertificateException {     } };

static public String SendHttpsPOST(String url, List<NameValuePair> param, String data) {         String result = null;                 //使用此工具可以将键值对编码成"Key=Value&Key2=Value2&Key3=Value3”形式的请求参数         String requestParam = URLEncodedUtils.format(param, "UTF-8");         try {             //设置SSLContext             SSLContext sslcontext = SSLContext.getInstance("TLS");             sslcontext.init(null, new TrustManager[]{myX509TrustManager}, null);            //打开连接        //要发送的POST请求url?Key=Value&Key2=Value2&Key3=Value3的形式            URL requestUrl = new URL(url + "?" + requestParam);            HttpsURLConnection httpsConn = (HttpsURLConnection)requestUrl.openConnection();            //设置套接工厂             httpsConn.setSSLSocketFactory(sslcontext.getSocketFactory());            //加入数据             httpsConn.setRequestMethod("POST");             httpsConn.setDoOutput(true);             DataOutputStream out = new DataOutputStream(                     httpsConn.getOutputStream());             if (data != null)                 out.writeBytes(data);                         out.flush();             out.close();            //获取输入流             BufferedReader in = new BufferedReader(new InputStreamReader(httpsConn.getInputStream()));             int code = httpsConn.getResponseCode();             if (HttpsURLConnection.HTTP_OK == code){                 String temp = in.readLine();                 /*连接成一个字符串*/                 while (temp != null) {                     if (result != null)                         result += temp;                     else                         result = temp;                     temp = in.readLine();                 }             }         } catch (KeyManagementException e) {             e.printStackTrace();         } catch (NoSuchAlgorithmException e) {             e.printStackTrace();         } catch (MalformedURLException e) {             e.printStackTrace();         } catch (ProtocolException e) {             e.printStackTrace();         } catch (IOException e) {             e.printStackTrace();         }        return result; }
