Magicodes.IE在Docker中使用
更新历史 2019.02.13 【Nuget】版本更新到2.0.2 【导入】修复单列导入的Bug，单元测试“OneColumnImporter_Test”。问题见（https://github.com/dotnetcore/Magicodes.IE/issues/35）。 【导出】修复导出HTML、Pdf、Word时，模板在某些情况下编译报错的问题。 【导入】重写空行检查。 2019.02.14 【Nuget】版本更新到2.1.0 【导出】PDF导出支持.NET 4.6.1，具体见单元测试
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.Excel
Install-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

COPY /simsun.ttc /usr/share/fonts/simsun.ttc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
