Question

我在htmlunit上创建了一些内容来阅读网页内容。但是我正在netwer上启用防火墙。我有我可以用来通过防火墙的凭证（我们使用此凭证访问互联网）。我不知道在哪里配置它。我尝试了以下但它没有用。有什么想法吗？

public class Sparsh {
private WebClient  webClient;
private final String userName,password,loginUrl="https://www.google.com";

public Sparsh(String userName,String password)

{
    this.userName=userName;
    this.password=password;
    webClient = new WebClient(BrowserVersion.CHROME);

DefaultCredentialsProvider cp = (DefaultCredentialsProvider)webClient.getCredentialsProvider();
cp.addCredentials("user", "password");
//cp.addProxyCredentials("myuser", "mypasswd");
webClient.getOptions().setUseInsecureSSL(true);
webClient.getOptions().setJavaScriptEnabled(true);

}


public boolean loginCheck() throws IOException
{
final HtmlPage page = webClient.getPage(loginUrl);
System.out.println(page.asText());

if (page.asText().contains("Service Catalog"))
    {
        return true;
    }
return false;
} public static void main(String[] Arg) throws IOException
{
  Sparsh snow=new Sparsh("xxxxxx","xxxxxx");
  snow.loginCheck();
  snow.close();
}
}

我收到以下错误

Answer 1

您是否可以通过此计算机上的浏览器访问google.com？如果是，则尝试设置代理。

webClient.getOptions.setProxyConfig(new ProxyConfig(proxy_host, proxy_port));

代理用户/密码应与您用于计算机的凭据（例如AD凭据）相同。

确保将域名添加到您的用户名。
