Redis可以做哪些事兒?

標籤：

    這裡介紹Redis可以做的其中兩件事:

  1.提供緩衝功能,作為快取服務器;

  2.輕量級的訊息佇列（ＭＱ）進行使用．

 

 /// <summary>    /// Redis協助類    /// </summary>    public class RedisHelper    {        /// <summary>        /// 往訊息佇列中放入資料        /// </summary>        /// <param name="listId">隊列Id</param>        /// <param name="value">資料</param>        public static void Enqueue(string listId, string value)        {            using (IRedisClient client = RedisManager.ClientManager.GetClient())            {                client.EnqueueItemOnList(listId, value);            }            return;        }        /// <summary>        /// 從訊息佇列中取出資料        /// </summary>        /// <param name="listId">隊列Id</param>        /// <returns></returns>        public static string Dequeue(string listId)        {            using (IRedisClient client = RedisManager.ClientManager.GetClient())            {                return client.DequeueItemFromList(listId);            }        }        /// <summary>        /// 從訊息佇列中取出資料        /// </summary>        /// <param name="redisClient"></param>        /// <param name="listId"></param>        /// <returns></returns>        public static string Dequeue(IRedisClient redisClient, string listId)        {            return redisClient.DequeueItemFromList(listId);        }        /// <summary>        /// Redis寫        /// </summary>        /// <typeparam name="T"></typeparam>        /// <param name="key">鍵</param>        /// <param name="value">值</param>        /// <param name="cacheTime">緩衝時間(分鐘)</param>        /// <returns></returns>        public static bool Set<T>(string key, T value, int cacheTime = 0)        {            using (IRedisClient client = RedisManager.ClientManager.GetClient())            {                if (cacheTime <= 0)                {                    return client.Set<T>(key, value);                }                return client.Set<T>(key, value, DateTime.Now.AddMinutes(cacheTime));            }        }        /// <summary>        /// Redis讀        /// </summary>        /// <typeparam name="T"></typeparam>        /// <param name="key">鍵</param>        /// <returns></returns>        public static T Get<T>(string key)        {            using (IRedisClient client = RedisManager.ClientManager.GetClient())            {                return client.Get<T>(key);            }        }    }    /// <summary>    /// Redis管理類    /// </summary>    public class RedisManager    {        public static PooledRedisClientManager ClientManager { get; private set; }        static RedisManager()        {            RedisClientManagerConfig redisConfig = new RedisClientManagerConfig();            redisConfig.MaxWritePoolSize = 128;            redisConfig.MaxReadPoolSize = 128;            ClientManager = new PooledRedisClientManager(new string[] { "127.0.0.1" }, new string[] { "127.0.0.1" }, redisConfig);        }    }

　　

訊息佇列資料消費方範例程式碼:

 JavaScriptSerializer serializer = new JavaScriptSerializer();            //資料消費者            while (true)            {                string data = RedisHelper.Dequeue("sendActiveEmail");                if (data != null)                {                    EmailModel emailModel = (EmailModel)serializer.Deserialize(data, typeof(EmailModel));                    Console.WriteLine("發送郵件:" + emailModel.MailTo);                    CommonHelper.SendEmail(emailModel.MailTo, emailModel.Subject, emailModel.Body, true);                    Console.WriteLine("發送郵件完成");                }                else                {                    Thread.Sleep(500);                }            }
