ServiceStack.Redis无法连接到Digitalocean托管的redis实例

Question

最近，我开始将job processor从Node.js转换到.net核心，并选择使用ServiceStack.Redis来管理到Redis的连接。

令人恼火的是，如果不抛出异常，我就无法让它连接到托管Redis。这个错误到底是什么意思，有什么线索吗？

var redisManager = new BasicRedisClientManager(0,Environment.GetEnvironmentVariable("REDIS"));
var redis = redisManager.GetClient();

Unhandled exception. ServiceStack.Redis.RedisResponseException: unknown command `ROLE`, with args beginning with:

任何其他人都会被这个问题困扰，特别是如果你使用的是来自DigitalOcean的托管REDIS。

本质上，角色命令(以及其他命令)不可用，因此在此库中，您必须设置以下标志。

RedisConfig.VerifyMasterConnections = false;
