Redis订阅的真实性和重试

问题描述

我在应用程序中使用ServiceStack.Redis，我的订阅方法是这样：

        protected void Subscribe(string channelsToSubscribe)
        {
            using IRedisClient redisClient = new RedisClient('127.0.0.1','6379');
            using var subscription = redisClient.CreateSubscription();
            subscription.OnMessage = (channel,msg) =>
            {
                // do something with the message
            };
            subscription.Subscribetochannels(channelsToSubscribe);
        }

问题：当我尝试订阅频道且Redis脱机时，我需要继续尝试直到连接稳定并正确订阅

所以我做到了：

        protected void Subscribe(string channelsToSubscribe)
        {
            try
            {
                using IRedisClient redisClient = new RedisClient('127.0.0.1','6379');
                using var subscription = redisClient.CreateSubscription();
                subscription.OnMessage = (channel,msg) =>
                {
                    // do something with the message
                };
                subscription.Subscribetochannels(channelsToSubscribe);
            }
            catch (Exception e)
            {
                // notify someone that an error happen
                Subscribe(channelsToSubscribe);
            }
        }

这可行，但是如果redis长时间离线，则递归堆栈在充满时会抛出错误（StackOverflowException）。

所以我将递归更改为do while循环：

    protected void Subscribe(string channelsToSubscribe)
        {
            using IRedisClient redisClient = new RedisClient('127.0.0.1','6379');
            using var subscription = redisClient.CreateSubscription();
            do
            {
                try
                {
                    subscription.OnMessage = (channel,msg) =>
                    {
                        // do something with the message
                    };

                    subscription.Subscribetochannels(channelsToSubscribe);
                }
                catch (Exception e)
                {
                    // notify someone that an error happen
                }
            } while (redisClient.Ping());
        }

但是似乎redisClient.Ping()也会在Redis断开连接时引发异常，我需要获取一个信息来告诉我Redis是否具有稳定的连接，有人知道解决方案吗？ >
