针对HttpURLConnection接口。
try {
String url = “https://58.215.139.22/?ws_domain=center.httpdns.com&ws_ret_type=json&ws_cli_IP=218.85.152.99”;
HttpsURLConnection connection = (HttpsURLConnection) new URL(url).openConnection();
connection.setRequestProperty(“Host”, “httpdns.wangsucloud.com”);
connection.setHostnameVerifier(new HostnameVerifier() {
/*

• 关于这个接口的说明，官方有文档描述：
• This is an extended verification option that implementers can provide.
• It is to be used during a handshake if the URL’s hostname does not match the
• peer’s identification hostname.
• 使用HTTPDNS后URL里设置的hostname不是远程的主机名(如:httpdns.wangsucloud.com)，与证书颁发的域不匹配，
• Android HttpsURLConnection提供了回调接口让用户来处理这种定制化场景。
• 在确认HTTPDNS返回的源站IP与Session携带的IP信息一致后，您可以在回调方法中将待验证域名替换为httpdns.wangsucloud.com进行验证。
