Go菜鸟关于switch问题求指点！

菜鸟求教，一个简单无限循环代码，但为什么输入bye，却无法结束呢？ package main import( "bufio" "fmt" "os" "strings" ) func main(){ inputReader := bufio.NewReader(os.Stdin) fmt.Println("Please input your name:") input,err := inputReader.ReadString('\n') if err!=nil{ fmt.Printf("An error occurred :%s\n", err) os.Exit(1) }else{ name := input[:len(input)-1] fmt.Printf("hello,%s What can i do for you!", name) } for { input,err = inputReader.ReadString('\n') if err!=nil{ fmt.Printf("An error occurred :%s\n", err) continue } input = input[:len(input)-1] input = strings.ToLower(input) switch input{ case "": continue case "bye": fmt.Println("bye!") os.Exit(0) default: fmt.Printf("Sorry,I didn't catch you.") } } }
