通过Java中的代理获取SSL页面的最简单方法

我想用Java获取一个SSL页面.问题是,我必须对http代理进行身份验证.

所以我想要一个简单的方法来获取这个页面.我尝试了Apache Commons httpclient,但这对我的问题来说太多了.

我尝试了这段代码,但它不包含身份验证操作:

import java.io.*;
import java.net.*;

public class ProxyTest {

  public static void main(String[] args) throws ClientProtocolException, IOException {

    URL url = new URL("https://ssl.site");
    Socket s = new Socket("proxy.address", 8080);
    Proxy proxy = new Proxy(Proxy.Type.HTTP, s.getLocalSocketAddress());

    URLConnection connection = url.openConnection(proxy);
    InputStream inputStream = connection.getInputStream();
    BufferedReader br = new BufferedReader(new InputStreamReader(inputStream));
    String tmpLine = "";

    while ((tmpLine = br.readLine()) != null) {
      System.out.println(tmpLine);
    }

  }
}

任何人都可以提供一些信息如何以简单的方式实现它？

提前致谢

在打开连接之前,需要设置java.net.Authenticator:

...

public static void main(String[] args) throws Exception {
    // Set the username and password in a manner which doesn't leave it visible.
    final String username = Console.readLine("[%s]", "Proxy Username");
    final char[] password = Console.readPassword("[%s"], "Proxy Password:");

    // Use a anonymous class for our authenticator for brevity
    Authenticator.setDefault(new Authenticator() {
        protected PasswordAuthentication getPasswordAuthentication() {
            return new PasswordAuthentication(username, password);
        }
    });

    URL url = new URL("https://ssl.site");
    ...
}

要在完成后删除身份验证器,请调用以下代码:

Authenticator.setDefault(null);

在Java SE 6所支持的认证HTTP Basic,HTTP Digest 和 NTLM.有关更多信息,请参阅sun.com上的Http身份验证文档
