redis - 如何使用 go-redis 运行 SENTINEL slaves 命令？

Question

我设置 Redis 客户端如下:

redisClient := redisclient.NewClient(&redisclient.Options{
    Addr:    <sentinel-pod-IP>:<sentinel-pod-port>,
    Password: "",
    DB:       0,
})

我跑了 SENTINEL slaves <master-name>命令通过:

import redisclient "github.com/go-redis/redis"

......

cmd := redisclient.NewStringSliceCmd("SENTINEL", "slaves", "master-name") 
redisClient.Process(cmd)
slaveInfos, err := cmd.Result()

但是，我在运行 redis: can't parse string reply: \"*40\" 时遇到错误.

SENTINEL get-master-addr-by-name <master-name>适用于相同的客户端设置。

我遇到了同样的问题，在github上找到了解决方案: https://github.com/go-redis/redis/issues/788

你需要使用NewSliceCmd，例如

        cmd := redis.NewSliceCmd("sentinel", "slaves", "clusterName-master")
        client.Process(cmd)
        _, err := cmd.Result()
        if err != nil {
            fmt.Printf("Unable to issue `sentinel slaves %s-master ` cmd on (%s): %s", clusterName, err.Error())
        }
