Install golang version sdk
go get -u github.com/tencentyun/cos-go-sdk-v5
The current bucket is xxxx , and the area is ap-beijing
According to two examples
copy
For example, if you want to copy /temp/a.png to /app/a.png :
the received two file path parameters are as follows:
source : xxxx.cos.ap-beijing.myqcloud.com/temp/a.png
target : app/a.png
delete
For example, if you want to delete /app/a.png :
the received two file path parameters are as follows:
target : app/a.png
Usage
Generally speaking, a complete address is obtained when using it, and copy and delete are performed according to the complete address, and two simple usage examples are written.
func CosCopyFile(source string) string {
base := "https://xxxx.cos.ap-beijing.myqcloud.com/"
u, _ := url.Parse(base)
b := &cos.BaseURL{
BucketURL: u}
client := cos.NewClient(b, &http.Client{
Transport: &cos.AuthorizationTransport{
SecretID: "id",
SecretKey: "secret",
},
})
var target string
target = strings.Replace(source, base, "", -1)
source = strings.Replace(source, "https://", "", -1)
target = strings.Replace(target, "temp", "app", -1)
// 移动对象
fmt.Printf("source is %+v\n", source)
fmt.Printf("target is %+v\n", target)
_, _, err := client.Object.Copy(context.Background(), target, source, nil)
if err == nil {
return base + target
}
fmt.Printf("err is %+v\n", err)
return ""
}
func CosDeleteFile(target string) {
base := "https://xxxx.cos.ap-beijing.myqcloud.com/"
u, _ := url.Parse("https://xxxx.cos.ap-beijing.myqcloud.com/")
b := &cos.BaseURL{
BucketURL: u}
client := cos.NewClient(b, &http.Client{
Transport: &cos.AuthorizationTransport{
SecretID: "id",
SecretKey: "secret",
},
})
target = strings.Replace(target, base, "", -1)
fmt.Printf("delete file %+v", target)
// 删除对象
_, err := client.Object.Delete(context.Background(), target)
if err != nil {
fmt.Printf("delete error %+v", err)
}
}
Example of use:
CosCopyFile("https://xxxx.cos.ap-beijing.myqcloud.com/temp/a.png")
CosDeleteFile("https://xxxx.cos.ap-beijing.myqcloud.com/app/a.png")
