我正在尝试使用未知的https链接打开构建Web服务， 我正在使用htts下面的代码来打开连接，但它失败了：
URL url = new URL(reg_url);
HttpsURLConnection httpsURLConnection = (HttpsURLConnection) url.openConnection();
httpsURLConnection.setRequestMethod("POST");
httpsURLConnection.setDoOutput(true);
OutputStream outputStream = httpsURLConnection.getOutputStream();
BufferedWriter bufferedWriter = new BufferedWriter(new OutputStreamWriter(outputStream, "UTF-8"));
如何继续而不是显示以下错误：
