本文介绍如何通过 TOS Go SDK 查询 Bucket 中基于 ObjectSet 标签配置的 QoS 与容量配额规则。

注意事项

如果未配置按标签配额规则，服务端可能返回配置不存在相关错误。

通过子账号调用时，需要具备当前 Bucket 的 tos:GetObjectSetQuotaByTag 权限。

示例代码

package main​
​
import (​
   "context"​
   "fmt"​
   "os"​
​
   "github.com/volcengine/ve-tos-golang-sdk/v2/tos"​
)​
​
func checkErr(err error) {​
   if err != nil {​
      if serverErr, ok := err.(*tos.TosServerError); ok {​
         fmt.Println("Error:", serverErr.Error())​
         fmt.Println("Request ID:", serverErr.RequestID)​
         fmt.Println("Response Status Code:", serverErr.StatusCode)​
         fmt.Println("Response Header:", serverErr.Header)​
         fmt.Println("Response Err Code:", serverErr.Code)​
         fmt.Println("Response Err Msg:", serverErr.Message)​
      } else if clientErr, ok := err.(*tos.TosClientError); ok {​
         fmt.Println("Error:", clientErr.Error())​
         fmt.Println("Client Cause Err:", clientErr.Cause.Error())​
      } else {​
         fmt.Println("Error:", err)​
      }​
      panic(err)​
   }​
}​
​
func main() {​
   var (​
      accessKey = os.Getenv("TOS_ACCESS_KEY")​
      secretKey = os.Getenv("TOS_SECRET_KEY")​
      // Bucket 对应的 Endpoint，以华北 2（北京）为例：https://tos-cn-beijing.volces.com​
      endpoint = "https://tos-cn-beijing.volces.com"​
      region   = "cn-beijing"​
      // 填写 BucketName​
      bucketName = "*** Provide your bucket name ***"​
      ctx        = context.Background()​
   )​
​
   // 初始化客户端​
   client, err := tos.NewClientV2(endpoint, tos.WithRegion(region), tos.WithCredentials(tos.NewStaticCredentials(accessKey, secretKey)))​
   checkErr(err)​
​
   getOutput, err := client.GetObjectSetQuotaByTag(ctx, &tos.GetObjectSetQuotaByTagInput{​
      Bucket: bucketName,​
   })​
   checkErr(err)​
   fmt.Println("GetObjectSetQuotaByTag Request ID:", getOutput.RequestID)​
   for _, rule := range getOutput.Rules {​
      fmt.Printf("Tag: %s=%s, StorageQuota: %s\n", rule.Tag.Key, rule.Tag.Value, rule.StorageQuota)​
      fmt.Println("Qos:", rule.Qos)​
   }​
}​
