Golang使用zlib压缩和解压缩字符串

package main
 
import (
 "bytes"
 "compress/zlib"
 "fmt"
 "io"
)
 
func main() {
 var in bytes.Buffer
 b := []byte(`xiorui.cc`)
 w := zlib.NewWriter(&in)
 w.Write(b)
 w.Close()
 
 var out bytes.Buffer
 r, _ := zlib.NewReader(&in)
 io.Copy(&out, r)
 fmt.Println(out.String())
 
}

func NewWriter
 
  func NewWriter(w io.Writer) *Writer

func NewReader
 
  func NewReader(r io.Reader) (io.ReadCloser, error)

const (
    NoCompression = 0
    BestSpeed   = 1
 
    BestCompression  = 9
    DefaultCompression = -1
)
 
const (
  NoCompression   = flate.NoCompression
  BestSpeed     = flate.BestSpeed
  BestCompression  = flate.BestCompression
  DefaultCompression = flate.DefaultCompression
)

func (*Writer) Write
 
  func (z *Writer) Write(p []byte) (n int, err error)

func (*Writer) Close
 
  func (z *Writer) Close() error
