怎么在Golang中使用zlib对字符串进行压缩和解压缩？相信很多没有经验的人对此束手无策，为此本文总结了问题出现的原因和解决方法，通过这篇文章希望你能解决这个问题。
zlib.NewWriter() 只能传递 []byte类型数据. NewWriterLevel 可以传递压缩的等级.
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())
}库包地址
import "compress/zlib"写入
func NewWriter func NewWriter(w io.Writer) *Writer
读取压缩的数据
func NewReader func NewReader(r io.Reader) (io.ReadCloser, error)
设置压缩等级，并压缩数据
func NewWriterLevel(w io.Writer, level int) (io.WriteCloser, os.Error)下面是几个级别.
const ( NoCompression = 0 BestSpeed = 1 BestCompression = 9 DefaultCompression = -1 ) const ( NoCompression = flate.NoCompression BestSpeed = flate.BestSpeed BestCompression = flate.BestCompression DefaultCompression = flate.DefaultCompression )
写入数据
func (*Writer) Write func (z *Writer) Write(p []byte) (n int, err error)
关闭
func (*Writer) Close func (z *Writer) Close() error
