HTML 到 PDF 转换

将 HTML 内容转换为 PDF 演示了基本的架构差异。

CraftMyPDF：

using RestSharp;
using System.IO;

class Program
{
    static void Main()
    {
        var client = new RestClient("https://api.craftmypdf.com/v1/create");
        var request = new RestRequest(Method.POST);
        request.AddHeader("X-API-KEY", "your-api-key");
        request.AddJsonBody(new
        {
            template_id = "your-template-id",
            data = new
            {
                html = "<h1>Hello World</h1><p>This is a PDF from HTML</p>"
            }
        });

        var response = client.Execute(request);
        File.WriteAllBytes("output.pdf", response.RawBytes);

CraftMyPDF 需要配置 REST 客户端、添加 API key 标头、构建带有模板 ID 的 JSON 体、执行 HTTP 请求、处理响应以及将原始字节写入文件。IronPDF创建一个 ChromePdfRenderer ，调用 RenderHtmlAsPdf() 并保存--无需网络调用、无需 API 密钥、无需模板 ID。

URL到PDF转换

将网页截取为 PDF 文档也显示出类似的复杂性差异。

        var request = new RestRequest(Method.POST);
        request.AddHeader("X-API-KEY", "your-api-key");
        request.AddJsonBody(new

CraftMyPDF 需要相同的 REST 客户端设置，但采用不同的 JSON 有效载荷结构。IronPDF的 RenderUrlAsPdf() 使用 Chromium 直接在本地渲染 URL。

CraftMyPDF 在发送到 API 的 JSON 数据有效载荷中嵌入页眉/页脚内容。IronPDF使用 RenderingOptions.TextHeader 和 RenderingOptions.TextFooter 属性与 TextHeaderFooter 对象，提供无需网络传输的类型化配置。
