ServiceStack.Redis 無法連接到 Digitalocean 托管的 redis 實例

Question

最近我開始將作業處理器從 Node.js 轉換為 .net core，並選擇使用 ServiceStack.Redis 來管理與 Redis 的連接。

令人討厭的是，如果不拋出異常，我無法讓它連接到托管的 Redis。 關於這個錯誤甚至意味着什么的任何線索？

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

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

其他任何人都會遇到這種情況，特別是如果您使用來自 DigitalOcean 的 Managed REDIS。

本質上 ROLE 命令（可能還有其他命令）不可用，所以在這個庫中你必須設置以下標志。

RedisConfig.VerifyMasterConnections = false;
