cmd命令交互

被测试端

package main

import (
	"bufio"
	"fmt"
	"os"
)

func main()  {
	input := bufio.NewScanner(os.Stdin)
	fmt.Println("999")
	for input.Scan() {
		line := input.Text()

		// 输入bye时 结束
		if line == "exit" {
			fmt.Println("结束")
			break
		}
		if line == "888888888888"{
			fmt.Println("99999999999999999999")
		}
		fmt.Println()
		// 更新key对应的val 新key对应的val是默认0值
	}
}
