了解 IronPDF 中的 Kerberos

如何讓 UrlToPdf 與 Kerberos 驗證搭配使用？

若要將 Kerberos 驗證與 IronPDF 的UrlToPdf一起使用，您應該在渲染設定中設定使用者名稱和密碼。 您可以參考 IronPDF 文件以了解更多詳情： IronPdf.ChromeHttpLoginCredentials 。

我們建議使用System.Net.Http.HttpClient下載 HTML 內容，然後再進行渲染。 這種方法可讓您在 IronPDF 處理內容之前處理 HTTP 請求，包括需要驗證的請求。

以下是關於使用 Kerberos 下載頁面的線上指南： System.Net.Http.HttpClient 如何選擇身份驗證類型？ 此 StackOverflow 連結提供了有關使用HttpClient實現身份驗證的詳細討論。

為了解析並確保下載 HTML 中的所有必要資源，請考慮使用 HTML Agility Pack。 這個 .NET 程式庫有助於有效地操作和查詢 HTML 文件。
