Translated View the article in English 如何使UrlToPdf在Kerberos身份驗證中運作? 要使用IronPDF的UrlToPdf進行Kerberos身份驗證,您應該在渲染設定中設置用戶名和密碼。 您可以參考IronPDF文檔以獲取更多詳情:IronPdf.ChromeHttpLoginCredentials。 我們建議使用System.Net.Http.HttpClient來下載HTML內容,這樣您可以隨後進行渲染。 這種方法允許您在IronPDF處理內容之前處理HTTP請求,包括那些需要身份驗證的請求。 以下是有關使用Kerberos下載頁面的在線指南:System.Net.Http.HttpClient如何選擇身份驗證類型?。 這個StackOverflow鏈接提供了有關使用HttpClient實現身份驗證的詳細討論。 為了解析並確保HTML中的所有必要資產被下載,考慮使用HTML Agility Pack。 這個.NET庫有助於有效地操作和查詢HTML文檔。 // Example: Using HttpClient with Kerberos Authentication // Import the necessary namespaces using System; using System.Net; using System.Net.Http; using System.Net.Http.Headers; using System.Threading.Tasks; namespace KerberosAuthenticationExample { class Program { static async Task Main(string[] args) { // Create an instance of HttpClient HttpClientHandler handler = new HttpClientHandler { // Automatically use default network credentials UseDefaultCredentials = true // Enables Windows authentication (e.g., Kerberos) }; using HttpClient httpClient = new HttpClient(handler); try { // Send a GET request to the desired URL HttpResponseMessage response = await httpClient.GetAsync("https://your-secure-url.com"); // Ensure the request was successful response.EnsureSuccessStatusCode(); // Read and display the response body string responseBody = await response.Content.ReadAsStringAsync(); Console.WriteLine(responseBody); // If needed, render the HTML to PDF with IronPDF here // IronPdf.HtmlToPdf renderer = new IronPdf.HtmlToPdf(); // renderer.RenderHtmlAsPdf(responseBody).SaveAs("output.pdf"); } catch (HttpRequestException e) { // Handle any error responses from the server or connection issues Console.WriteLine("\nException Caught!"); Console.WriteLine($"Message :{e.Message}"); } } } } // Example: Using HttpClient with Kerberos Authentication // Import the necessary namespaces using System; using System.Net; using System.Net.Http; using System.Net.Http.Headers; using System.Threading.Tasks; namespace KerberosAuthenticationExample { class Program { static async Task Main(string[] args) { // Create an instance of HttpClient HttpClientHandler handler = new HttpClientHandler { // Automatically use default network credentials UseDefaultCredentials = true // Enables Windows authentication (e.g., Kerberos) }; using HttpClient httpClient = new HttpClient(handler); try { // Send a GET request to the desired URL HttpResponseMessage response = await httpClient.GetAsync("https://your-secure-url.com"); // Ensure the request was successful response.EnsureSuccessStatusCode(); // Read and display the response body string responseBody = await response.Content.ReadAsStringAsync(); Console.WriteLine(responseBody); // If needed, render the HTML to PDF with IronPDF here // IronPdf.HtmlToPdf renderer = new IronPdf.HtmlToPdf(); // renderer.RenderHtmlAsPdf(responseBody).SaveAs("output.pdf"); } catch (HttpRequestException e) { // Handle any error responses from the server or connection issues Console.WriteLine("\nException Caught!"); Console.WriteLine($"Message :{e.Message}"); } } } } ' Example: Using HttpClient with Kerberos Authentication ' Import the necessary namespaces Imports Microsoft.VisualBasic Imports System Imports System.Net Imports System.Net.Http Imports System.Net.Http.Headers Imports System.Threading.Tasks Namespace KerberosAuthenticationExample Friend Class Program Shared Async Function Main(ByVal args() As String) As Task ' Create an instance of HttpClient Dim handler As New HttpClientHandler With {.UseDefaultCredentials = True} Using httpClient As New HttpClient(handler) Try ' Send a GET request to the desired URL Dim response As HttpResponseMessage = Await httpClient.GetAsync("https://your-secure-url.com") ' Ensure the request was successful response.EnsureSuccessStatusCode() ' Read and display the response body Dim responseBody As String = Await response.Content.ReadAsStringAsync() Console.WriteLine(responseBody) ' If needed, render the HTML to PDF with IronPDF here ' IronPdf.HtmlToPdf renderer = new IronPdf.HtmlToPdf(); ' renderer.RenderHtmlAsPdf(responseBody).SaveAs("output.pdf"); Catch e As HttpRequestException ' Handle any error responses from the server or connection issues Console.WriteLine(vbLf & "Exception Caught!") Console.WriteLine($"Message :{e.Message}") End Try End Using End Function End Class End Namespace $vbLabelText $csharpLabel 關鍵點: HttpClient和HttpClientHandler:使用HttpClientHandler並設置UseDefaultCredentials = true來允許使用當前用戶的憑證進行Kerberos身份驗證。 錯誤處理:實現try-catch塊以管理HTTP請求過程中的異常。 HTML渲染:一旦HTML被獲取,如果需要,利用IronPDF將內容渲染成PDF。 Curtis Chau 立即與工程團隊聊天 技術作家 Curtis Chau 擁有卡爾頓大學計算機科學學士學位,專注於前端開發,擅長於 Node.js、TypeScript、JavaScript 和 React。Curtis 熱衷於創建直觀且美觀的用戶界面,喜歡使用現代框架並打造結構良好、視覺吸引人的手冊。除了開發之外,Curtis 對物聯網 (IoT) 有著濃厚的興趣,探索將硬體和軟體結合的創新方式。在閒暇時間,他喜愛遊戲並構建 Discord 機器人,結合科技與創意的樂趣。 準備好開始了嗎?
