我正在尝试构建一个登录页面。为此，我想打开 SSL 套接字并发出 HTTPS 请求，但我在该行中收到未知主机异常

SSLSocket skt = (SSLSocket)sslsf.createSocket("https://31.21.18.222/room_info/x.txt" , 443);

有人可以告诉我我做错了什么吗？另外，我已经关闭了主机验证，因为我的程序中不需要它。

`public void clickLogin() throws IOException, CertificateException, KeyStoreException, NoSuchAlgorithmException, KeyManagementException {

            HttpsURLConnection connection = null;
            KeyStore keyStore = KeyStore.getInstance(KeyStore.getDefaultType());
            keyStore.load(null);        //Make an empty store
            InputStream fis = new FileInputStream("C:/Documents and Settings/user/Desktop/PK/localhost.crt"); 
            BufferedInputStream bis = new BufferedInputStream(fis);
            CertificateFactory cf = CertificateFactory.getInstance("X.509");
            while (bis.available() > 0) {
                java.security.cert.Certificate cert = cf.generateCertificate(bis);
                keyStore.setCertificateEntry("localhost", cert);
            }
