**模板代码如下**
```html
```
**上传代码实现如下**
```go
package controllers
import (
"path"
"crypto/md5"
"time"
"fmt"
"github.com/astaxie/beego"
"math/rand"
"os"
)
type UploadController struct{
beego.Controller
}
func (this *UploadController) UpForm(){
this.TplName = "upload.tpl"
}
func (this *UploadController) UpFile(){
f, h, _ := this.GetFile("myfile")//获取上传的文件
ext := path.Ext(h.Filename)
//验证后缀名是否符合要求
var AllowExtMap map[string]bool = map[string]bool{
".jpg":true,
".jpeg":true,
".png":true,
}
if _,ok:=AllowExtMap[ext];!ok{
this.Ctx.WriteString( "后缀名不符合上传要求" )
return
}
//创建目录
uploadDir := "static/upload/" + time.Now().Format("2006/01/02/")
err := os.MkdirAll( uploadDir , 777)
if err != nil {
this.Ctx.WriteString( fmt.Sprintf("%v",err) )
return
}
//构造文件名称
rand.Seed(time.Now().UnixNano())
randNum := fmt.Sprintf("%d", rand.Intn(9999)+1000 )
hashName := md5.Sum( []byte( time.Now().Format("2006_01_02_15_04_05_") + randNum ) )
fileName := fmt.Sprintf("%x",hashName) + ext
//this.Ctx.WriteString( fileName )
fpath := uploadDir + fileName
defer f.Close()//关闭上传的文件，不然的话会出现临时文件不能清除的情况
err = this.SaveToFile("myfile", fpath)
if err != nil {
this.Ctx.WriteString( fmt.Sprintf("%v",err) )
}
this.Ctx.WriteString( "上传成功~！！！！！！！" )
}
