JAVA 怎么实现HTTP的POST方式通讯，以及HTTPS方式传递

/** * 执行post请求并将返回内容转为json格式返回 */public static JsonObject doPost(String url, JsonObject message)throws WeiXinException {JsonObject jo = null;PrintWriter out = null;InputStream in = null;try {if (url.startsWith("https")){//https方式提交需要SSLContext sc = SSLContext.getInstance("SSL");sc.init(null, new TrustManager[] { new TrustAnyTrustManager() },new java.security.SecureRandom());URL console = new URL(url);HttpsURLConnection conn = (HttpsURLConnection) console.openConnection();conn.setSSLSocketFactory(sc.getSocketFactory());conn.setHostnameVerifier(new TrustAnyHostnameVerifier());conn.connect();in = conn.getInputStream();}else{in = new URL(url).openStream();}// 打开和URL之间的连接URLConnection conn = new URL(url).openConnection();// 设置通用的请求属性conn.setRequestProperty("accept", "*/*");conn.setRequestProperty("connection", "Keep-Alive");conn.setRequestProperty("user-agent","Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1;SV1)");// 发送POST请求必须设置如下两行conn.setDoOutput(true);conn.setDoInput(true);// 获取URLConnection对象对应的输出流out = new PrintWriter(conn.getOutputStream());// 发送请求参数out.print(message.toString());// flush输出流的缓冲out.flush();// POST请求out.flush();out.close();in = conn.getInputStream();jo = JSON.parse(getContext(in));doExeption(jo);} catch (MalformedURLException e) {e.printStackTrace();} catch (ProtocolException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();} catch (KeyManagementException e) {e.printStackTrace();} catch (NoSuchAlgorithmException e) {e.printStackTrace();} finally {if (out != null) {out.flush();out.close();}if (in != null ){try {in.close();} catch (IOException e) {e.printStackTrace();}}}return jo;}2015-07-17
