读取写入tar/zip文件（go语言）

1.读取写入tar文件

package main

import (
    "archive/tar"
    "fmt"
    "os"
    "bufio"
    "io"
)

func readFile(path string) string{
    var content string = ""
    file,err := os.Open(path)
    if err != nil{
        fmt.Printf("%v",err)
        return ""
    }

    defer file.Close()

    inputReader := bufio.NewReader(file)
    for{
        inputString,err := inputReader.ReadString('\n')
        content += inputString
        if err == io.EOF{
            break
        }
    }

    return content
}

func tarPackage(tarFileName string,tarFileList []string,rootPath string){
    fw,err := os.Create(rootPath+"/"+tarFileName)
    if err != nil{
        fmt.Printf("%v",err)
        return
    }
    defer fw.Close()

    tw := tar.NewWriter(fw)
    defer tw.Close()

    for _,fileItem := range tarFileList{
        body := readFile(rootPath+"/"+fileItem)

        hdr := &tar.Header{
            Name:fileItem,
            Mode:0600,
            Size:int64(len(body)),
        }

            return
        }
        if _,err := tw.Write([]byte(body));err != nil{
            fmt.Printf("%v",err)
            return
        }
    }

    fmt.Println("done!")
}

            fmt.Printf("%v",err)
            continue
        }

        fmt.Println("filename:"+hdr.Name)
    }
}
