One 、 download

stay go.mod Introduction in

github.com/qiniu/api.v7/v7 v7.8.2

Introduce... Into the controller

"github.com/qiniu/api.v7/v7/auth/qbox"
"github.com/qiniu/api.v7/v7/storage"

A warning will appear when using this

But it will not affect the upload

Two 、 Use steps （ Just beginning to learn go, All is to save the picture locally first , Then upload ）

1. Save to local

fileSuffix := ".png"
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) + fileSuffix
imageUrl := "static/img/" + fileName
err := u.SaveToFile("image", imageUrl)
if err != nil {
	u.Ctx.WriteString(fmt.Sprintf("%v", err))
	return
}
u.Ctx.WriteString(" Upload local successfully ~！！！！！！！")
u.Ctx.WriteString(imageUrl)

The location to save the local is static/img, If not, please create . 

2. Cloud storage （ Here is the manual of seven cattle cloud ）

The code is as follows ：

bucket, _ := beego.AppConfig.String("bucket")
putPolicy := storage.PutPolicy{
Scope: bucket,
}
accessKey, _ := beego.AppConfig.String("accessKey")
secretKey, _ := beego.AppConfig.String("secretKey")
mac := qbox.NewMac(accessKey, secretKey)
upToken := putPolicy.UploadToken(mac)
cfg := storage.Config{}
//  The computer room corresponding to the space 
cfg.Zone = &storage.ZoneHuadong
//  Whether to use https domain name 
cfg.UseHTTPS = true
//  Upload whether to use CDN Upload acceleration 
cfg.UseCdnDomains = true
//  Build the object that the form Uploads 
formUploader := storage.NewFormUploader(&cfg)
ret := storage.PutRet{}
//  Optional configuration 
putExtra := storage.PutExtra{
Params: map[string]string{
"x:name": "github logo",
},
}
localFile := imageUrl
//imageUrl：static/img/7bc0954e8edfc48895e7c33c280a66d3.png
key := "shopping/userinfo/" + fileName // File location after storage ,shopping Folder  userinfo Folder  filename File name 
err = formUploader.PutFile(context.Background(), &ret, upToken, key, localFile, &putExtra)
if err != nil {
fmt.Println(err)
return
}
u.Ctx.WriteString(" Successful cloud storage ")

key： It refers to the location where the image is stored after uploading to the space

localFile： Indicates the address of the file to be uploaded

here “ Build the object that the form Uploads ” Not very well understood , I'll add it later .

There are better methods to supplement later , I hope the big guys can give advice ！
