今天来说下gobox中的encoding和shell两个box。
encoding
encoding的主要作用是完成编解码工作，目前支持了base64编解码。
用法示例
package main
import (
"github.com/goinbox/encoding"
"fmt"
)
func main() {
coded := encoding.Base64Encode([]byte("test goinbox base64 encoding"))
fmt.Println("coded:", string(coded))
uncoded := encoding.Base64Decode(coded)
fmt.Println("uncoded:", string(uncoded))
}
输出效果示例
coded: dGVzdCBnb2luYm94IGJhc2U2NCBlbmNvZGluZw==
uncoded: test goinbox base64 encoding
shell
shell提供了简单的执行shell命令的方法
简单执行命令
示例：
package main
import (
"github.com/goinbox/shell"
"fmt"
)
func main() {
result := shell.RunCmd("ls -l /home/ligang")
fmt.Println("exec ok:", result.Ok)
fmt.Println("exec output:", string(result.Output))
}
结果输出：
exec ok: true
exec output: total 52
drwxrwxr-x 3 ligang ligang 4096 4月 3 17:40 backup
drwxr-xr-x 2 ligang ligang 4096 4月 3 17:54 Desktop
drwxrwxr-x 10 ligang ligang 4096 4月 20 17:45 devspace
drwxr-xr-x 2 ligang ligang 4096 4月 3 17:33 Documents
drwxr-xr-x 2 ligang ligang 4096 4月 3 17:33 Downloads
drwxrwxr-x 4 ligang ligang 4096 4月 4 10:20 gopath
drwxr-xr-x 2 ligang ligang 4096 4月 3 17:33 Music
drwxr-xr-x 2 ligang ligang 4096 4月 3 17:33 Pictures
drwxr-xr-x 2 ligang ligang 4096 4月 3 17:33 Public
drwxrwxr-x 3 ligang ligang 4096 4月 3 18:12 soft
drwxr-xr-x 2 ligang ligang 4096 4月 3 17:33 Templates
drwxrwxr-x 9 ligang ligang 4096 5月 8 11:03 tmp
drwxr-xr-x 2 ligang ligang 4096 4月 3 17:33 Videos
以其它用户身份执行
示例：
package main
import (
"github.com/goinbox/shell"
"fmt"
)
func main() {
result := shell.RunAsUser("ls -l /root", "root")
fmt.Println("exec ok:", result.Ok)
fmt.Println("exec output:", string(result.Output))
}
结果输出：
[sudo] password for ligang:
exec ok: true
exec output: total 0
执行rsync
示例：
package main
import (
"github.com/goinbox/shell"
"os/user"
"fmt"
)
func main() {
sou := "./tmp/rsync/sou/"
dst := "./tmp/rsync/dst/"
file := "rsync.txt"
cmd := "mkdir -p " + sou + "; mkdir -p " + dst + "; /bin/echo 'rsync sou' > " + sou + file
shell.RunCmd(cmd)
currentUser, _ := user.Current()
sshUser := currentUser.Username
result := shell.Rsync(sou, dst, "", sshUser, 3)
fmt.Println(string(result.Output))
}
结果输出：
sending incremental file list
rsync.txt
sent 140 bytes received 39 bytes 358.00 bytes/sec
total size is 10 speedup is 0.06
从shell脚本中读取指定变量值
示例：
package main
import (
"github.com/goinbox/shell"
"fmt"
)
func main() {
//eg: params.sh
//user_name="zhangsan"
//nick_name="lisi"
//sex="boy"
shellScript := "params.sh"
paramMap := map[string]string{
"user_name": "user_name",
"nick_name": "nick_name",
"user_sex": "sex",
}
params := shell.GetParamsFromShell(shellScript, paramMap)
fmt.Println(params)
}
输出：
map[user_name:zhangsan nick_name:lisi user_sex:boy]
