使用Select.HtmlToPdf.NetCore 把html内容生成pdf文件

引用类库

通过nuget查找Select.HtmlToPdf.NetCore并引用

控制器使用

自己写一个页面，或者找个可用的网站都可以测试
代码如下

        /// <summary>
        /// 导出pdf
        /// </summary>
        /// <returns></returns>
        [HttpGet]
        public async Task<IActionResult> Export(string url)
        {
            SelectPdf.HtmlToPdf converter = new SelectPdf.HtmlToPdf();
            //converter.Options.PdfPageOrientation = SelectPdf.PdfPageOrientation.Landscape;
            SelectPdf.PdfDocument doc = converter.ConvertUrl(url);//"http://localhost:5020/PRINT/DyColdStoragePrint"

            var path = "wwwroot/pdf/" + DateTime.Now.ToString("yyyyMMdd") + "/test.pdf";
            doc.Save(path);
            doc.Close();

            return Content(path.Replace("wwwroot/", ""));
        }

问题

只能在windows上使用，无法跨平台，会报错

官方表明只能支持windows,比较遗憾
