无法通过代理隧道 - Jsoup

Question

我在创建 HTTP 连接时遇到以下异常。

2017-08-07 17:07:43,219 ERROR au.com.scraper.sites.ScraperSite - Exception in parsing Categories: Unable to tunnel through proxy. Proxy returns "HTTP/1.1 403 Forbidden" at line number 153

下面是我的代理配置。

Authenticator.setDefault(new ProxyAuthenticator("user_name", "password"));
System.setProperty("https.proxyHost", server);
System.setProperty("https.proxyPort", port);
System.setProperty("http.proxyHost", server);
System.setProperty("http.proxyPort", port);

下面是我的代理验证器类。

package au.com.scraper;
import java.net.Authenticator;
import java.net.PasswordAuthentication;
public class ProxyAuthenticator extends Authenticator
{
    public ProxyAuthenticator(String user, String password)
    {
        this.user = user;
        this.password = password;
    }
    protected PasswordAuthentication getPasswordAuthentication()
    {
        return new PasswordAuthentication(user, password.toCharArray());
    }
    private String user;
    private String password;
}

谁能说明为什么会出现这个问题？

您的代理服务器可能会阻止该网址，当网址是本地地址并且您的代理服务器将阻止该地址时，我们可能会遇到此问题。
