.NET(C#) 使用PuppeteerSharp将HTML转成PDF

1、安装引用PuppeteerSharp

1）使用Nuget界面管理器

直接分别搜索 "PuppeteerSharp"，找到对应的点安装即可。

相关文档：VS(Visual Studio)中Nuget的使用

2）使用Package Manager命令安装

PM> Install-Package PuppeteerSharp

2、使用PuppeteerSharp将URL中HTML转换PDF

Puppeteer Sharp 是官方Node.JS Puppeteer API的 .NET API，使用PuppeteerSharp将HTML转换PDF。转换代码如下，

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;using PuppeteerSharp;using PuppeteerSharp.Media;namespace ConsoleApplication{    class Program    {        public static string outputFile { get; private set; }         async static void Main(string[] args)        {            using var browserFetcher = new BrowserFetcher();            outputFile = "/home/wonhero.pdf";            await browserFetcher.DownloadAsync(BrowserFetcher.DefaultChromiumRevision);            var browser = await Puppeteer.LaunchAsync(new LaunchOptions            {                Headless = true            });            var page = await browser.NewPageAsync();            await page.GoToAsync("http://www.google.com");            await page.PdfAsync(outputFile, new PdfOptions            {                Format = PaperFormat.A4,                DisplayHeaderFooter = true,                MarginOptions = new MarginOptions                {                    Top = "20px",                    Right = "20px",                    Bottom = "40px",                    Left = "20px"                },                FooterTemplate = "Footer Text"            });            Console.ReadKey();        }    }}

3、将 HTML 字符串转换为 PDF

HTML字符串也可以使用PuppeteerSharp转换为PDF。代码如下，

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;using PuppeteerSharp;using PuppeteerSharp.Media;namespace ConsoleApplication{    class Program    {        public static string outputFile { get; private set; }        async static void Main(string[] args)        {            using var browserFetcher = new BrowserFetcher();            outputFile = "/home/wonhero.pdf";            await browserFetcher.DownloadAsync(BrowserFetcher.DefaultChromiumRevision);            var browser = await Puppeteer.LaunchAsync(new LaunchOptions            {                Headless = true            });            //var page = await browser.NewPageAsync();            using (var page = await browser.NewPageAsync())            {                await page.SetContentAsync("www.wonhero.com");                var result = await page.GetContentAsync();                await page.PdfAsync(outputFile, new PdfOptions                {                    Format = PaperFormat.A4,                    DisplayHeaderFooter = true,                    MarginOptions = new MarginOptions                    {                        Top = "20px",                        Right = "20px",                        Bottom = "40px",                        Left = "20px"                    },                    FooterTemplate = "Footer Text"                });                Console.ReadKey();            }        }    }}
