设置多版本对象访问权限

您可以通过ObsClient.SetObjectAcl接口传入版本号（VersionId）设置多版本对象的访问权限，示例代码如下：

// 引入依赖包
import (
       "fmt"
       "obs"
)
 
var ak = "*** Provide your Access Key ***"
var sk = "*** Provide your Secret Key ***"
var endpoint = "https://your-point"
 
// 创建ObsClient结构体
var obsClient, _ = obs.New(ak, sk, endpoint)
 
func main() {
       input := &obs.SetObjectAclInput{}
       input.Bucket = "bucketname"
       input.Key = "objectkey"
       input.VersionId = "versionid"
 
       // 通过预定义访问策略设置指定版本对象的访问权限为公共读
       input.ACL = obs.AclPublicRead
       output, err := obsClient.SetObjectAcl(input)
       if err == nil {
              fmt.Printf("RequestId:%s\n", output.RequestId)
       } else if obsError, ok := err.(obs.ObsError); ok {
              fmt.Printf("Code:%s\n", obsError.Code)
              fmt.Printf("Message:%s\n", obsError.Message)
       }
 
       // 直接设置指定版本对象的访问权限
       input.Owner.ID = "ownerid"
       var grants [3]obs.Grant
       // 为所有用户设置写权限
       grants[0].Grantee.Type = obs.GranteeGroup
       grants[0].Grantee.URI = obs.GroupAllUsers
       grants[0].Permission = obs.PermissionWrite
 
       // 为指定用户设置完全控制权限
       grants[1].Grantee.Type = obs.GranteeUser
       grants[1].Grantee.ID = "granteeid"
       grants[1].Permission = obs.PermissionFullControl
 
       // 为所有用户设置读权限
       grants[2].Grantee.Type = obs.GranteeGroup
       grants[2].Grantee.URI = obs.GroupAllUsers
       grants[2].Permission = obs.PermissionRead
       input.Grants = grants[0:3]
 
       output, err = obsClient.SetObjectAcl(input)
       if err == nil {
              fmt.Printf("RequestId:%s\n", output.RequestId)
       } else if obsError, ok := err.(obs.ObsError); ok {
              fmt.Printf("Code:%s\n", obsError.Code)
              fmt.Printf("Message:%s\n", obsError.Message)
       }
}

说明：

所有者ID或者被授权用户ID，是指用户的账户ID，可通过OBS控制台“我的凭证”页面查看。

获取多版本对象访问权限

您可以通过ObsClient.GetObjectAcl接口传入版本号（VersionId）获取多版本对象的访问权限，示例代码如下：

// 引入依赖包
import (
       "fmt"
       "obs"
)
 
var ak = "*** Provide your Access Key ***"
var sk = "*** Provide your Secret Key ***"
var endpoint = "https://your-endpoint"
 
// 创建ObsClient结构体
var obsClient, _ = obs.New(ak, sk, endpoint)
 
func main() {
       input := &obs.GetObjectAclInput{}
       input.Bucket = "bucketname"
       input.Key = "objectkey"
       input.VersionId = "versionid"
 
       output, err := obsClient.GetObjectAcl(input)
       if err == nil {
              fmt.Printf("Owner.ID:%s\n", output.Owner.ID)
              for index, grant := range output.Grants {
                     fmt.Printf("Grant[%d]-Type:%s, ID:%s, URI:%s, Permission:%s\n", index, grant.Grantee.Type, grant.Grantee.ID, grant.Grantee.URI, grant.Permission)
              }
       } else if obsError, ok := err.(obs.ObsError); ok {
              fmt.Printf("Code:%s\n", obsError.Code)
              fmt.Printf("Message:%s\n", obsError.Message)
       }
}
