golang中的excel上传,读取数据

package test

import "github.com/plandem/xlsx"

//学生结构体
type Stu struct {
    Name string
    Age  string
}

//读取表中数据,返回list
func RedExcel()([]Stu) {
    filePath :="./test.xlsx"  
    list := make([]Stu,0)  
    //定义表头映射的字段数组
    head:=[]string{"name","age"}
    xl, err := xlsx.Open(filePath)
    if err != nil {
            fmt.Print("err")
        return list
    }
    defer xl.Close() 
    sheet := xl.Sheet(0, xlsx.SheetModeStream)
    totalCols, totalRows := sheet.Dimension()
    for row := 1; row < totalRows; row++ {
        stu := Stu{
            Name: "",
            Age: "",
        }
        for col := 0; col < totalCols; col++ {
            value := sheet.Cell(col, row).String()
            field :=head[col]
            switch field {
            case "name":
                stu.Name=value
            case "age":
                stu.Age=value
            }
        }
        list=append(list,stu)
