我正在Go編寫命令行應用程序,並且希望將redis端點指定爲標誌。我已經添加了以下情況:從Codegansta獲取標誌值CLI
app.Flags = []cli.Flag{
cli.StringFlag{
Name: "redis, r",
Value: "127.0.0.1",
Usage: "redis host to listen to",
EnvVar: "REDIS_URL",
},
}
然而,在我的命令,該標誌始終是空白:
return cli.Command{
Name: "listen",
Usage: "Listen to a stream",
Action: func(c *cli.Context) {
redisUrl := c.String("redis")
log.Printf("Connecting to redis: %s\n", redisUrl)
},
}
調用時:
./mantle-monitor --redis 127.0.0.1 listen
我在做什麼錯?
就是這樣。謝謝! – brandonhilkert
