說明

本章主要說明使用Magicodes.IE，在Docker環境中的配置.

要點

• 通過Dto進行Excel導出

• 導出PDF數據

• Docker配置

示例

導出示例：

Install-Package Magicodes.IE.Excel Install-Package Magicodes.IE.Pdf

• 導出Excel

[ExcelExporter(Name = "學生信息", TableStyle = "Light10", AutoFitAllColumn = true,MaxRowNumberOnASheet = 2)]public class StudentExcel{/// <summary>/// 姓名/// </summary>[ExporterHeader(DisplayName = "姓名")]public string Name { get; set; }/// <summary>/// 年齡/// </summary>[ExporterHeader(DisplayName = "年齡")]public int Age { get; set; }/// <summary>/// 備注/// </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歲",Birthday=DateTime.Now},new StudentExcel{Name = "MR.B",Age = 19,Remarks = "我叫MR.B,今年19歲",Birthday=DateTime.Now},new StudentExcel{Name = "MR.C",Age = 20,Remarks = "我叫MR.C,今年20歲",Birthday=DateTime.Now}});return File("test.xlsx", "application/ms-excel", result.FileName);}

• 導出PDF

[PdfExporter(Name = "學生信息")]public class StudentPdf{/// <summary>/// 姓名/// </summary>[ExporterHeader(DisplayName = "姓名")]public string Name { get; set; }/// <summary>/// 年齡/// </summary>[ExporterHeader(DisplayName = "年齡")]public int Age { get; set; }/// <summary>/// 備注/// </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歲",Birthday=DateTime.Now},new StudentPdf{Name = "MR.B",Age = 19,Remarks = "我叫MR.B,今年19歲",Birthday=DateTime.Now},new StudentPdf{Name = "MR.C",Age = 20,Remarks = "我叫MR.C,今年20歲",Birthday=DateTime.Now}});return File("test.pdf", "application/pdf", result.FileName);}

通過上述代碼我們創建了一個導出示例，
具體特性屬性可以看一下前兩篇文章?基礎教程之導出Excel?、基礎教程之導出Pdf收據

Dockerfile配置

注意，以上基礎鏡像使用：(ccr.ccs.tencentyun.com/magicodes/aspnetcore-runtime:latest) ,該鏡像GitHub地址：(https://github.com/xin-lai/aspnetcore-docker)。

推薦理由：

• 加快鏡像構建和拉取速度，加速CI\CD構建以及提高開發體驗

• 時區默認設置為東八區，見“ENV TZ=Asia/Shanghai”

• 默認安裝了libgdiplus等庫，以便支持Excel導入導出

• 目前提供了騰訊云的公共鏡像和hub.docker的公共鏡像，大家可以按需
