我一直在尝试使用ioredis连接到azure中的redis三节点集群。
当我使用redis.cluster构造函数连接时：

new Redis.Cluster(['host.redis.cache.windows.net', 6380], {
    scaleReads: 'all',
    slotsRefreshTimeout: 2000,
    redisOptions: {
        password: 'some-secret',
        tls: true as any
    },
});

我得到的错误是：

2020-06-04T13:05:41.788Z ioredis:redis status[127.0.0.1:6380 (ioredisClusterRefresher)]: [empty] -> wait

使用非群集redis连接时：

new Redis(6380, 'host.redis.cache.windows.net', { password: 'some-secret' });

我得到的错误是：

020-06-04T15:04:08.609Z ioredis:redis status[10.211.x.x:6380]: connecting -> connect
2020-06-04T15:04:08.614Z ioredis:redis write command[10.211.x.x:6380]: 0 -> auth([ 'some-secret' ])

    at TCP.onStreamRead (internal/stream_base_commons.js:111:27) errno: 'ECONNRESET', code: 'ECONNRESET', syscall: 'read' }

如您所见，它在端口6380上使用tls。azure为我提供了一个主机+端口组合和两个不同的访问密钥（主/辅）-我觉得很奇怪，我应该使用哪个访问密钥？我也不确定我是否应该在集群模式下连接，但我更愿意获得集群的好处。当我这样做时，它似乎试图在 127.0.0.1:6380 这可能是不正确的。
在azure的快速启动中，他们使用节点\u redis连接：

var redis = require("redis");

// Add your cache name and access key.
var client = redis.createClient(6380, process.env.REDISCACHEHOSTNAME,
    {auth_pass: process.env.REDISCACHEKEY, tls: {servername: process.env.REDISCACHEHOSTNAME}});

我希望这里的人也能遇到同样的问题并解决它。
谢谢！
