1. flag库的基本用法 下面是一个golang flag库的命令行demo程序 func main() { wordPtr := flag.String("word", "Jude", "a string") numPtr := flag.Int("numb", 42, "an int") boolPtr := flag.Bool("fork", false, "a bool") var svar string flag.StringVar(&svar, "svar", "bar"...
1)flag.Xxx(),其中 Xxx 可以是 Int、String,Bool 等;返回一个相应类型的指针,如: var ip = flag.Int("flagname", 1234, "help message for flagname") 第一个参数 :flag名称为flagname 第二个参数 :flagname默认值为1234 第三个参数 :flagname的提示信息 返回的ip是指针类型,所以这种方式获取ip的值...

Golang标准库中提供了功能。flag库是非常基础的功能,在实践上也非常有用,在做命令行交互程序时候必不可少。package main import "flag"import "fmt"import "os"func main() { if len(os.Args) < 2 { fmt.Println("too less param")return } var ip = flag.Int("num", 1234, "help message for ...
