我有一个网站,其网址以“http://”,但是是给我一个例外,与消息 - 不支持的协议:HTTPS。 有没有可能是该网站是否使用HTTPS协议还是它的URL开始以“http://”,而不是“https://开头”。
public ActionForward executeAction(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
ActionForward forward = mapping.findForward(Constants.SUCCESS);
String link = "http://abc.fgh.jkl.mno";
URL thisURL;
HttpURLConnection conn = null;
try {
thisURL = new URL(link);
conn = (HttpURLConnection) thisURL.openConnection();
System.out.println(conn.getResponseCode());
System.out.println(conn.getResponseMessage());
} catch (Exception ex) {
ex.printStackTrace();
}
return forward;
}
