Czar.HtmlToPdfImage

1、安装NUGET包

-- .netcore
install-package Czar.HtmlToPdfImage.AspNetCore
-- .net
install-package Czar.HtmlToPdfImage

2、配置运行参数

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
        {
            .......
            //配置运行路径
            WkhtmltoxConfig.Setup(env.WebRootPath);
            //WkhtmltoxConfig.Setup(env.WebRootPath,"custompath"); //配置wwwroot下个文件地址，默认为Wkhtmltox,注意windows和linux需要使用不同的exe
        }

3、使用案例

        /// save image on server and response as image
        /// </summary>
        /// <param name="url"></param>
        /// <returns></returns>

            //var model = new TestModel { Name = "Giorgio" };
            //var image= new ViewAsImage("About",model);
            //image.PageWidth = 800;
            //image.PageHeight = 600;
            //return image;

            //way 2:
            var image = new UrlAsImage(url);
            image.SaveOnServerPath = Path.Combine("wwwroot/files/image", DateTime.Now.ToString("yyyyMMddhhmmss") + ".png");
            return image;

            return pdf;
        }
