如何存储一个字节片?

I would like to understand how to store several byte slices separately in a slice. As hopefully illustrated below, I want the storage struct to store the result of the compressed result of n found in buf.

type storage struct 
{
    compressed []byte 
}       

func (s* storage) compress(n []byte) {
      var buf bytes.Buffer
      w := gzip.NewWriter(&buf)
      w.Write(n)
      w.Close()
      store := buf.Bytes()
      s.compressed = append(s.compressed, store)
}

    In your code compressed is a slice of bytes. If you want to store slices of bytes you need a slice of slices of bytes. So change the type of compressed to [][]byte
