我用 Java 编写了一个小代码来访问 URL。该代码适用于 HTTP 连接，但适用于 HTTPS（错误粘贴在下面）
任何解决此问题的帮助将不胜感激。
代码 ：
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.URL;
import java.net.URLConnection;
public class ConnectToWCProd {
public static void main(String[] args) throws Exception {
String userPassword = "user1:user1";
String encoding = new sun.misc.BASE64Encoder().encode (userPassword.getBytes());
//URL oracle = new URL("http://<URL>/");
URL oracle = new URL("https://<URL>");
URLConnection yc = oracle.openConnection();
yc.setRequestProperty("Authorization", "Basic " + encoding);
BufferedReader in = new BufferedReader(new InputStreamReader(yc.getInputStream()));
String inputLine;
while ((inputLine = in.readLine()) != null)
System.out.println(inputLine);
in.close();
}
}
错误 ：
