      Enabling Guetzli Compression

      Feature description

      This API is used to enable the Guetzli compression feature for a bucket.

      Method prototype

      func (s *CIService) PutGuetzli(ctx context.Context) (*Response, error)

      Sample request

      // `CIURL` is required
      u, _ := url.Parse("https://examplebucket-1250000000.cos.ap-guangzhou.myqcloud.com")
      cu, _ := url.Parse("http://examplebucket-1250000000.pic.ap-guangzhou.myqcloud.com")
      b := &cos.BaseURL{BucketURL: u, CIURL: cu}
      c := cos.NewClient(b, &http.Client{
          Transport: &cos.AuthorizationTransport{
              SecretID:  os.Getenv("SECRETID"),
              SecretKey: os.Getenv("SECRETKEY"),

      b := &cos.BaseURL{BucketURL: u, CIURL: cu}
      c := cos.NewClient(b, &http.Client{
          Transport: &cos.AuthorizationTransport{
              SecretID:  os.Getenv("SECRETID"),
              SecretKey: os.Getenv("SECRETKEY"),
          },
      })
      
      res, _, err := c.CI.GetGuetzli(context.Background())
      if err == nil {
          fmt.Printf("%v\\n", res.GuetzliStatus)
      }

      Response description
