为什么这不起作用?(抱歉,由于某种原因,我无法在 Go Playground 上获得分享按钮)。
package main
import (
"bytes"
"compress/gzip"
"fmt"
"io"
)
func main() {
// ENCODE
data := []byte{1, 2, 3, 4, 5, 6, 7}
bb0 := bytes.NewBuffer(data)
byts := bb0.Bytes()
fmt.Printf("data = % x\n", data)
fmt.Printf("byte buffer bb0 contains = % x\n", byts)
bb1 := new(bytes.Buffer)
w := gzip.NewWriter(bb1)
s1, err := w.Write(byts)
fmt.Printf("%d bytes written using gzip writer, err = %v\n", s1, err)
byts = bb1.Bytes()
fmt.Printf("byte buffer bb1 contains = % x\n", byts)
// DECODE
r, err := gzip.NewReader(bb1)
bb2 := new(bytes.Buffer)
s2, err := io.Copy(bb2, r)
r.Close()
fmt.Printf("%d bytes copied from gzip reader, err = %v\n", s2, err)
byts = bb2.Bytes()
fmt.Printf("byte buffer bb2 contains = % x\n", byts)
}
我得到的输出
data = 01 02 03 04 05 06 07
byte buffer bb0 contains = 01 02 03 04 05 06 07
7 bytes written using gzip writer, err = <nil>
byte buffer bb1 contains = 1f 8b 08 00 00 09 6e 88 00 ff
0 bytes copied from gzip reader, err = unexpected EOF
byte buffer bb2 contains =
读者似乎什么都没做,我做错了什么?
