知识小结-03go语言xlxs的使用

读取excel文件代码：

import(
	"fmt"
	"github.com/tealeg/xlsx"
)

var (
	inFile = "/Users/chain/Downloads/student1.xlsx"
)

func Import(){
	// 打开文件
    xlFile, err := xlsx.OpenFile(inFile)
    if err != nil {
		fmt.Println(err.Error())
		return
	}
	// 遍历sheet页读取
    for _, sheet := range xlFile.Sheets {
		fmt.Println("sheet name: ", sheet.Name)
		//遍历行读取
        for _, row := range sheet.Rows {
			// 遍历每行的列读取
            for _, cell := range row.Cells {
				text := cell.String()
                fmt.Printf("%20s", text)
			}
			fmt.Print("\n")
        }
	}
	fmt.Println("\n\nimport success")
}
测试代码：

import(
	"testing"
)

func TestImport(t *testing.T){
	Import()
}
Write
import(
	"strconv"
	"fmt"
	"github.com/tealeg/xlsx"
)

var (
	inFile = "/Users/chain/Downloads/student1.xlsx"
	outFile = "/Users/chain/Downloads/out_student.xlsx"
)

type Student struct{
	Name string
	age int
	Phone string
	Gender string
	Mail string
}

func Export(){
    file := xlsx.NewFile()
    sheet, err := file.AddSheet("student_list")
    if err != nil {
        fmt.Printf(err.Error())
	}
	stus := getStudents()
	//add data
	for _, stu := range stus{
		row := sheet.AddRow()
		nameCell := row.AddCell()
		nameCell.Value = stu.Name

		ageCell := row.AddCell()
		ageCell.Value = strconv.Itoa(stu.age)

		phoneCell := row.AddCell()
		phoneCell.Value = stu.Phone

		genderCell := row.AddCell()
		genderCell.Value = stu.Gender

		mailCell := row.AddCell()
		mailCell.Value = stu.Mail
	}
    err = file.Save(outFile)
    if err != nil {
        fmt.Printf(err.Error())
	}
	fmt.Println("\n\nexport success")
}

func getStudents()[]Student{
	students := make([]Student, 0)
	for i := 0; i < 10; i++{
		stu := Student{}
		stu.Name = "name" + strconv.Itoa(i + 1)
		stu.Mail = stu.Name + "@chairis.cn"
		stu.Phone = "1380013800" + strconv.Itoa(i)
		stu.age = 20
		stu.Gender = "男"
		students = append(students, stu)
	}
	return students
}
测试代码：

import(
	"testing"
)

func TestExport(t *testing.T){
	Export()
}

操作Excelize
安装Excelize：

go get github.com/Luxurioust/excelize

创建XLSX文件：

package main
 
import (
    "fmt"
    "os"
 
    "github.com/Luxurioust/excelize"
)
 
func main() {
    xlsx, err := excelize.CreateFile()
    if err != nil {
        fmt.Println(err)
        os.Exit(1)
    }
    xlsx.NewSheet(2, "Sheet2")
    xlsx.NewSheet(3, "Sheet3")
    xlsx.SetCellInt("Sheet2", "A23", 10)
    xlsx.SetCellStr("Sheet3", "B20", "Hello")
    err = xlsx.WriteTo("/home/Workbook.xlsx")
    if err != nil {
        fmt.Println(err)
        os.Exit(1)
    }
}

写XLSX文件：

package main
 
import (
    "fmt"
    "os"
 
    "github.com/Luxurioust/excelize"
)
 
func main() {
    xlsx, err := excelize.OpenFile("/home/Workbook.xlsx")
    if err != nil {
        fmt.Println(err)
        os.Exit(1)
    }
    xlsx.SetCellInt("Sheet2", "B2", 100)
    xlsx.SetCellStr("Sheet2", "C11", "Hello")
    xlsx.NewSheet(3, "TestSheet")
    xlsx.SetCellInt("Sheet3", "A23", 10)
    xlsx.SetCellStr("Sheet3", "b230", "World")
    xlsx.SetActiveSheet(2)
    err = xlsx.Save()
    if err != nil {
        fmt.Println(err)
        os.Exit(1)
    }
}

读XLSX文件：

package main
 
import (
    "fmt"
    "os"
 
    "github.com/Luxurioust/excelize"
)
 
func main() {
    xlsx, err := excelize.OpenFile("/home/Workbook.xlsx")
    if err != nil {
        fmt.Println(err)
        os.Exit(1)
    }
    cell := xlsx.GetCellValue("Sheet2", "D11")
    fmt.Println(cell)
}

下载制定版本的第三方库

https://github.com/360EntSecGroup-Skylar/excelize/releases/tag/v1.4.1

直接下载源码压缩文件，解压后放入对应的目录

重启编译器

go语言读取excel数据

https://xuri.me/excelize/zh-hans/base/installation.html#read

go自带函数c.Ctx.Output.Download()下载xlsx模版，传入参数xlsx的路径，与模版名

// 下载账单
func (c *BillController) DownloadTemplate() {
   olog.Debug("下载账单")
   var input UploadTypeInput
   r := otool.ParseRequestParams(&input, &c.Controller)
   if r.IsOk() {
      filePath := fmt.Sprintf("static/%s_bill_template.xlsx", input.ResourceType)
      templateName := fmt.Sprintf("%s账单模板.xlsx", input.ResourceType)
      c.Ctx.Output.Download(filePath, templateName)
   }
}
