golang zip 操作示例

下面的代码，来之golang的示例源码，其中涉及的常见zip文件，修改了部分代码，

在ExampleWriter中添加了如下

fw, err := os.Create("/home/xxx/mem_sub/go/z.zip")
    if err != nil {
        //panic(err)
  fmt.Println(err)
  return
    }
    defer fw.Close()

// Create a buffer to write our archive to.
//	buf := new(bytes.Buffer)

使之能够创建看的见的zip文件

package main
import (
 "archive/zip"
//	"bytes"
 "fmt"
 "io"
 "log"
 "os"
)
func ExampleWriter() {
 
 fw, err := os.Create("/home/xxx/mem_sub/go/z.zip")
    if err != nil {
        //panic(err)
  fmt.Println(err)
  return
    }
    defer fw.Close()
 
 // Create a buffer to write our archive to.
//	buf := new(bytes.Buffer)
 // Create a new zip archive.
 w := zip.NewWriter(fw)
 // Add some files to the archive.
 var files = []struct {
  Name, Body string
 }{
  {"readme.txt", "This archive contains some text files."},
  {"gopher.txt", "Gopher names:\nGeorge\nGeoffrey\nGonzo"},
  {"todo.txt", "Get animal handling licence.\nWrite more examples."},
 }
 for _, file := range files {
  f, err := w.Create(file.Name)
  if err != nil {
   log.Fatal(err)
  }
  _, err = f.Write([]byte(file.Body))
  if err != nil {
   log.Fatal(err)
  }
 }
 // Make sure to check the error on Close.
 err = w.Close()
 if err != nil {
  log.Fatal(err)
 }
}
func ExampleReader() {
 // Open a zip archive for reading.
 r, err := zip.OpenReader("ss.zip")
 if err != nil {
  log.Fatal(err)
 }
 defer r.Close()
 // Iterate through the files in the archive,
 // printing some of their contents.
 for _, f := range r.File {
  fmt.Printf("Contents of %s:\n", f.Name)
  rc, err := f.Open()
  if err != nil {
   log.Fatal(err)
  }
  _, err = io.CopyN(os.Stdout, rc, 68)
  if err != nil {
   log.Fatal(err)
  }
  rc.Close()
  fmt.Println()
 }
 // Output:
 // Contents of README:
 // This is the source code repository for the Go programming language.
}
func main(){
 ExampleWriter()
 //ExampleReader()
}
