说明

本章主要说明使用Magicodes.IE，在Docker环境中的配置.

要点

  • 通过Dto进行Excel导出
  • 导出PDF数据
  • Docker配置

示例

导出示例：

Install-Package Magicodes.IE.ExcelInstall-Package Magicodes.IE.Pdf
  • 导出Excel
    [ExcelExporter(Name = "学生信息", TableStyle = "Light10", AutoFitAllColumn = true,        MaxRowNumberOnASheet = 2)]    public class StudentExcel    {        /// <summary>        ///     姓名        /// </summary>        [ExporterHeader(DisplayName = "姓名")]        public string Name { get; set; }        /// <summary>        ///     年龄        /// </summary>        [ExporterHeader(DisplayName = "年龄")]        public int Age { get; set; }        /// <summary>        ///     备注        /// </summary>        public string Remarks { get; set; }        /// <summary>        ///     出生日期        /// </summary>        [ExporterHeader(DisplayName = "出生日期", Format = "yyyy-mm-DD")]        public DateTime Birthday { get; set; }    }
        public async Task<IActionResult> ExporterExcel() {            IExporter exporter = new ExcelExporter();                       var result = await exporter.Export(Path.Combine("wwwroot","test.xlsx"), new List<StudentExcel>()                {                    new StudentExcel                    {                        Name = "MR.A",                        Age = 18,                        Remarks = "我叫MR.A,今年18岁",                        Birthday=DateTime.Now                    },                    new StudentExcel                    {                        Name = "MR.B",                        Age = 19,                        Remarks = "我叫MR.B,今年19岁",                        Birthday=DateTime.Now                    },                    new StudentExcel                    {                        Name = "MR.C",                        Age = 20,                        Remarks = "我叫MR.C,今年20岁",                        Birthday=DateTime.Now                    }                });            return File("test.xlsx", "application/ms-excel", result.FileName);        }
  • 导出PDF
    [PdfExporter(Name = "学生信息")]    public class StudentPdf    {        /// <summary>        ///     姓名        /// </summary>        [ExporterHeader(DisplayName = "姓名")]        public string Name { get; set; }        /// <summary>        ///     年龄        /// </summary>        [ExporterHeader(DisplayName = "年龄")]        public int Age { get; set; }        /// <summary>        ///     备注        /// </summary>        public string Remarks { get; set; }        /// <summary>        ///     出生日期        /// </summary>        [ExporterHeader(DisplayName = "出生日期", Format = "yyyy-mm-DD")]        public DateTime Birthday { get; set; }    }
        public async Task<IActionResult> ExporterPdf() {            var exporter = new PdfExporter();            var result = await exporter.ExportListByTemplate(Path.Combine("wwwroot", "test.pdf"), new List<StudentPdf>()            {                 new StudentPdf                    {                        Name = "MR.A",                        Age = 18,                        Remarks = "我叫MR.A,今年18岁",                        Birthday=DateTime.Now                    },                    new StudentPdf                    {                        Name = "MR.B",                        Age = 19,                        Remarks = "我叫MR.B,今年19岁",                        Birthday=DateTime.Now                    },                    new StudentPdf                    {                        Name = "MR.C",                        Age = 20,                        Remarks = "我叫MR.C,今年20岁",                        Birthday=DateTime.Now                    }            });            return File("test.pdf", "application/pdf", result.FileName);        }

通过上述代码我们创建了一个导出示例，
具体特性属性可以看一下前两篇文章 基础教程之导出Excel 、基础教程之导出Pdf收据

Dockerfile配置

注意，以上基础镜像使用：(ccr.ccs.tencentyun.com/magicodes/aspnetcore-runtime:latest) ,该镜像GitHub地址：(https://github.com/xin-lai/aspnetcore-docker)。

推荐理由：

  • 加快镜像构建和拉取速度，加速CI\CD构建以及提高开发体验
  • 时区默认设置为东八区，见“ENV TZ=Asia/Shanghai”
  • 默认安装了libgdiplus等库，以便支持Excel导入导出
  • 目前提供了腾讯云的公共镜像和hub.docker的公共镜像，大家可以按需
