使用 Redis 架构 URL 连接到 Redis 服务器

Question

我正在尝试连接到托管在这样的 url 上的 Redis 服务器。

redis://h:asdfqwer1234asdf@ec2-111-1-1-1.compute-1.amazonaws.com:38799

我尝试过使用 2 个库，但它们都无法连接到服务器。我使用过redix.v3和go-redis。

redix.v3当使用上面类似的 URL 时，我遇到了恐慌错误。

我收到go-redis一个关于网址中冒号太多的错误，我尝试使用 [redis://h:asdfqwer1234asdf@ec2-111-1-1-1.compute-1.amazonaws.com]:38799某些帖子中建议的这个网址。

还是没有运气。有人成功连接到Redis服务器吗？

redix.v3 的代码和错误

func main() {
    fmt.Println("running")
    client, err := radix.NewPool("tcp", "redis://h:asdfqwer1234asdf@ec2-111-1-1-1.compute-1.amazonaws.com:38799", 10)
    if err != nil {
        // handle error
    }

    var fooVal string
    err = client.Do(radix.Cmd(&fooVal, "SET", "foo", "hello"))
    fmt.Println(err, fooVal)
}

错误：

go-redis 的代码和错误

client := redis.NewClient(&redis.Options{
        Addr:     "redis://h:asdfqwer1234asdf@ec2-111-1-1-1.compute-1.amazonaws.com:38799",
        Password: "", // no password set
        DB:       0,  // use default DB
    })

// setup eviction policy on the redis client
client.ConfigSet("maxmemory", Config.RedisMaxMemory)
client.ConfigSet("maxmemory-policy", "allkeys-lru")

_, err := client.Ping().Result()

if err != nil {
    log.Println("Redis: failed to connect", err)
} else {
    log.Println("Redis: connected")
}

错误：

2018/10/08 10:57:29 Redis: failed to connect dial tcp: address redis://h:asdfqwer1234asdf@ec2-111-1-1-1.compute-1.amazonaws.com:38799: too many colons in address

可以使用go-redis中的ParseURL函数

opt, _ := redis.ParseURL("redis://:qwerty@localhost:6379")
client := redis.NewClient(opt)
