使用Net將HTML簡歷匯出為PDF格式

現在有許多將HTML匯出PDF的第三方包，這裡介紹使用的是Select.HtmlToPdf.NetCore

使用Select.HtmlToPdf.NetCore

整體思路是將cshtml內容讀出來，然後再轉為Pdf檔案
讀取cshtml內容有兩種方法，第一種使用第三方包 RazorEngine.NetCore，第二種使用官方方法進行讀取。（注意兩種方法的cshtml內容略有不同）

我把所有的原始碼都上傳到了我的個人Github，有需要的請自取：https://github.com/WeiMing0803/ExportPdf

首先使用`ChatGPT`生成個人簡歷資訊

程式碼部分

HomeController.cs :

public async Task<IActionResult> ToPdf()
{
    PdfDocument pdfDocument = new PdfDocument();
    HtmlToPdf converter = new HtmlToPdf();//範例化一個html到pdf轉換器物件
    converter.Options.PdfPageOrientation = PdfPageOrientation.Portrait;//設定頁面方向
    converter.Options.PdfPageSize = PdfPageSize.A4;//設定頁面大小
    converter.Options.MarginTop = 10;//設定頁邊距
    converter.Options.MarginBottom = 10;
    converter.Options.MarginLeft = 10;
    converter.Options.MarginRight = 10;

    PdfReportModel model = new PdfReportModel { Name = "彭于晏", Email = "[email protected]" };
    //string htmlResult = readByEngineRazor(model);//第一種方法，使用RazorEngine.NetCore讀取Cshtml檔案
    string htmlResult = await readCshtml(model);//第二種方法
    
    if (!string.IsNullOrEmpty(htmlResult))
    {
        pdfDocument = converter.ConvertHtmlString(htmlResult);
    }
    
    string savePath = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), $@"ExportPDF\{DateTime.Now.ToString("yyyyMMdd")}");
    Directory.CreateDirectory(savePath);
    string filename = Path.Combine(savePath, $"{DateTime.Now.ToString("yyyyMMddHHmmssffff")}.pdf");
    pdfDocument.Save(filename);

    byte[] bytes = System.IO.File.ReadAllBytes(filename);
    return File(bytes, "application/pdf", Path.GetFileName(filename));
}

 private string readByEngineRazor(PdfReportModel model)
{
    string template = System.IO.File.ReadAllText("Views/Report/PdfReport.cshtml");
    string htmlResult = Engine.Razor.RunCompile(template, "PdfReport", typeof(PdfReportModel), model);
    return htmlResult;
}

private async Task<string> readCshtml(PdfReportModel model)
{
    string htmlResult = await _viewRenderService.RenderToStringAsync("Report/PdfReport", model);
    return htmlResult;
}

TemplateGadgetProvider.cs :

public class TemplateGadgetProvider
{
    public static TemplateGadgetProvider _instance;
    public static TemplateGadgetProvider Instance
    {
        get
        {
            if (_instance == null)
                _instance = new TemplateGadgetProvider();
            return _instance;
        }
    }

    public string Load(string virtualPath)
    {
        return File.ReadAllText(virtualPath);
    }
}

PdfReport.cshtml :

使用RazorEngine.NetCore需要修改下面兩處地方

刪除 @model PdfReportModel

將@Html.Raw(@style) 修改為 @@Raw(@style)
