示例1: userGrantRevoke

func userGrantRevoke(c *cli.Context, grant bool) {
	roles := c.StringSlice("roles")
	if len(roles) == 0 {
		fmt.Fprintln(os.Stderr, "No roles specified; please use `-roles`")
		os.Exit(1)
	}

	api, user := mustUserAPIAndName(c)
	ctx, cancel := context.WithTimeout(context.Background(), client.DefaultRequestTimeout)
	currentUser, err := api.GetUser(ctx, user)
	cancel()
	if currentUser == nil {
		fmt.Fprintln(os.Stderr, err.Error())
		os.Exit(1)
	}

	ctx, cancel = context.WithTimeout(context.Background(), client.DefaultRequestTimeout)
	var newUser *client.User
	if grant {
		newUser, err = api.GrantUser(ctx, user, roles)
	} else {

	}
	cancel()
	sort.Strings(newUser.Roles)
	sort.Strings(currentUser.Roles)
