JavaでHTMLUnitを使用して、リモートURLに接続し、取得したWebページからいくつかの情報を取得しています。
私は次のコードを使用しています:
final WebClient webClient = new WebClient(BrowserVersion.INTERNET_EXPLORER_6_0, "companyproxy.server", 8080);
final DefaultCredentialsProvider scp = new DefaultCredentialsProvider();
scp.addProxyCredentials("username", "password","companyproxy.server",8080);
webClient.setCredentialsProvider(scp);
final URL url = new URL("http://htmlunit.sourceforge.net");
final HtmlPage page = (HtmlPage)webClient.getPage(url);
System.out.println(page.asXml());
プロキシサーバーの詳細を入力した後、次のエラーメッセージが表示されます。
