go - 如何在 Cobra golang 中使用子命令？

Question

抱歉，我找不到使用示例的方法

./client echo --times 10 "coucou" 
./client  --times 10 "coucou" echo

无法使用它...抱歉我的错误。

最好的问候，尼古拉斯

    func main() {
    var echoTimes int

    var cmdEcho = &cobra.Command{
        Use:   "echo [string to echo]",
        Short: "Echo anything to the screen",
        Long:  `echo is for echoing anything back.
        Echo works a lot like print, except it has a child command.
        `,
        Run: func(cmd *cobra.Command, args []string) {
            fmt.Println("Print: " + strings.Join(args, " "))
        },
    }

    var cmdTimes = &cobra.Command{
        Use:   "times [# times] [string to echo]",
        Short: "Echo anything to the screen more times",
        Long:  `echo things multiple times back to the user by providing
        a count and a string.`,
        Run: func(cmd *cobra.Command, args []string) {
            for i:=0; i < echoTimes; i++ {
                fmt.Println("Echo: " + strings.Join(args, " "))
            }
        },
    }

    cmdTimes.Flags().IntVarP(&echoTimes, "times", "t", 1, "times to echo the input")
    var rootCmd = &cobra.Command{Use: "app"}
    rootCmd.AddCommand(cmdEcho)
    cmdEcho.AddCommand(cmdTimes)
    rootCmd.Execute()
}

如果 times 是一个命令，您不应该在它前面加上 '--'。

您可以在 cobra_test.go 中看到的示例显示 times 用法如下:

echo times -j 99 one two
echo times -s again -c test here
