Go语言获取命令行参数学习笔记
直接获取命令行参数切片
- 通过
os.Args获取命令行参数切片
从命令行执行程序时所有的命令行参数都会存储在os.Args切片中
for index, value := range os.Args {
...
}
通过键值对获取命令行参数
- 如果通过
可执行文件.exe -u root -p root运行程序，则可以通过flag.StringVar()方法无视顺序获取-key后面的值
import flag
var username string
flag.StringVar(&username, "u", "默认值", "对参数的描述")
var password string
flag.StringVar(&password, "p", "默认值", "对参数的描述")
flag.Parse()
