GoFrame 命令管理-終端交互

基本介紹

?gcmd?組件支持從終端讀取用戶輸入數(shù)據(jù)，常用于終端交互場景。

相關(guān)方法：

func Scan(info ...interface{}) string
func Scanf(format string, info ...interface{}) string

這兩個(gè)方法都是向終端展示給定的信息，自動(dòng)讀取終端用戶輸入的信息返回，通過回車符號返回。

Scan使用

package main

import (
	"fmt"

	"github.com/gogf/gf/v2/os/gcmd"
)

func main() {
	name := gcmd.Scan("What's your name?\n")
	fmt.Println("Your name is:", name)
}

執(zhí)行后，交互示例：

> What's your name?
john
> Your name is: john

Scanf使用

package main

import (
	"fmt"

	"github.com/gogf/gf/v2/os/gcmd"
)

func main() {
	name := gcmd.Scan("> What's your name?\n")
	age := gcmd.Scanf("> Hello %s, how old are you?\n", name)
	fmt.Printf("> %s's age is: %s", name, age)
}

執(zhí)行后，交互示例：

> What's your name?
john
> Hello john, how old are you?
18
> john's age is: 18
