Golang gzip压缩bytes和解压bytes

实现方法

func main() {
    size := 1
    datasSlice := make([][]byte, size)
    for i := 0; i < size; i++ {
        datasSlice[i], _ = ioutil.ReadFile("images/" + strconv.Itoa(i+1) + ".jpg")
        fmt.Println("raw size:", strconv.Itoa(i)+".jpg :", len(datasSlice[i]))
    }
    var b bytes.Buffer
    w := gzip.NewWriter(&b)
    defer w.Close()
 
    for i := 0; i < size; i++ {
        w.Write(datasSlice[i])
    }
    w.Flush()
    fmt.Println("gzip size:", len(b.Bytes()))
 
    r, _ := gzip.NewReader(&b)
    defer r.Close()
    undatas, _ := ioutil.ReadAll(r)
    fmt.Println("ungzip size:", len(undatas))
}
