我想用cobra创建golang CLI。目前,它运行良好。我创建了类似foobar create --username johndoe
的东西。但我需要像foobar create user --username johndoe
这样的子命令。有user
子命令。
我创建了参数匹配,
var applicationCmd = &cobra.Command{
Use: "application",
Short: "Create/Read/Update application",
Long: `You can create any user or partner.`,
Run: (cmd *cobra.Command, args []string) {
if len(args) < 1 {
fmt.Printf("%sPlease choose any object that you want to change e.g (user, partner)%s\n", chalk.Red, chalk.Reset)
}
if stringUtil.Contains(args, "user") {
createUser()
}
if stringUtil.Contains(args, "partner") {
createPartner()
}
},
}
但我认为有一种更好的方法可以使用眼镜蛇而不是像这样匹配参数。有什么建议吗?

(在你发布答案之前我已经开始研究这个问题了,但是我并不想废弃这些代码)
package main
import (
"github.com/spf13/cobra"
"fmt"
)
var rootCmd = &cobra.Command{
Use: "app",
Run: func (cmd *cobra.Command, args []string) {
},
}
var makeU = &cobra.Command{
Use: "makeU",
Short: "makes a user",
Long: "Prints stuff about the user. You could also use the flags in your addPartner() function",
Run: func (cmd *cobra.Command, args []string) {
fmt.Println("User's name: " + uName)
fmt.Println("User's number: " + uNumber)
fmt.Println("User's other stuff: " + uOtherStuff)
},
}
var makeP = &cobra.Command{
Use: "makeP",
Short: "makes a partner",
Long: "Prints stuff about the partner. You could also use the flags in your addPartner() function",
Run: func (cmd *cobra.Command, args []string) {
fmt.Println("Partner's name: " + uName)
fmt.Println("Partner's number: " + uNumber)
fmt.Println("Partner's other stuff: " + uOtherStuff)
},
}
// adds commands
func addCommands() {
rootCmd.AddCommand(makeU)
rootCmd.AddCommand(makeP)
}
// adds flags
var pName, pNumber, pOtherStuff string
var uName, uNumber, uOtherStuff string
func init() {
makeU.Flags().StringVar(&uName, "username", "default", "--username=<user's name>")
makeU.Flags().StringVar(&uNumber, "usernumber", "default", "--usernumber=<user's number>")
makeU.Flags().StringVar(&uOtherStuff, "userother", "default", "--userother=<user's other stuff>")
makeP.Flags().StringVar(&pName, "partnername", "default", "--partnername=<partner's name>")
makeP.Flags().StringVar(&pNumber, "partnernumber", "default", "--partnernumber=<partner's number>")
makeP.Flags().StringVar(&pOtherStuff, "partnerother", "default", "--partnerother=<partner's other stuff>")
}
func main() {
addCommands()
rootCmd.Execute()
}

我已经解决了这个问题。只需将新的眼镜蛇命令添加到applicationCmd
,就像这样
applicationCmd.AddCommand(yourNewCommand)
