Redis-Service.Stack的初级使用

主要解决Redis服务器带有密码的情况下初始化。

 

创建RedisHelper类，直接贴代码：

 
using ServiceStack.Redis;
using System;
class RedisHelper
    {
        private static readonly PooledRedisClientManager pool = null;
        private static readonly string[] redisHosts = null;
        public static int RedisMaxReadPool = 1000;
        public static int RedisMaxWritePool = 1000;

        static RedisHelper()
        {
            //不带密码的ip地址：ip:port
            //带有密码的ip地址：password@ip:port
            var redisHostStr = "123456@192.168.1.10:6379";

            if (!string.IsNullOrEmpty(redisHostStr))
            {
                redisHosts = redisHostStr.Split(',');

                if (redisHosts.Length > 0)
                {
                    pool = new PooledRedisClientManager(redisHosts, redisHosts,
                        new RedisClientManagerConfig()
                        {
                            MaxWritePoolSize = RedisMaxWritePool,
                            MaxReadPoolSize = RedisMaxReadPool,
                            AutoStart = true
                            
                        });
                   
                }
            }
        }
        public static void Add<T>(string key, T value, DateTime expiry)
        {
            if (value == null)
            {
                return;
            }

            if (expiry <= DateTime.Now)
            {
                Remove(key);

                return;
            }

            try
            {
                if (pool != null)
                {
                    using (var r = pool.GetClient())
                    {
                        if (r != null)
                        {
                            r.SendTimeout = 1000;
                            r.Set(key, value, expiry - DateTime.Now);
                        }
                    }
                }
            }
            catch (Exception ex)
            {
                string msg = string.Format("{0}:{1}发生异常!{2}", "cache", "存储", key);
                Log(msg);
            }

        }

        public static void Add<T>(string key, T value, TimeSpan slidingExpiration)
        {
            if (value == null)
            {
                return;
            }

            if (slidingExpiration.TotalSeconds <= 0)
            {
                Remove(key);

                return;
            }

            try

            catch (Exception ex)
            {
                string msg = string.Format("{0}:{1}发生异常!{2}", "cache", "存储", key);
                Log(msg);
            }

        }



        public static T Get<T>(string key)
        {
            if (string.IsNullOrEmpty(key))
            {

                    {
                        if (r != null)
                        {

                        }
                    }
                }

            {
                if (pool != null)
                {
                    using (var r = pool.GetClient())
                    {
                        if (r != null)
                        {

                }
            }
            catch (Exception ex)

        }

        public static bool Exists(string key)
        {

            {

                        }
                    }

            return false;
        }

        static void Log(string s)
        {
            Console.WriteLine("RedisHelper:"+s);
        }
    }

使用方法：

    class Program
    {
        static void Main(string[] args)
        {
            string name = RedisHelper.Get<string>("name:1");
            Console.WriteLine(name);

            //add user object
            //User user = new User()
            //{
            //    UserToken = "庄周",
            //    Password = "123456",
            //    Age = 100
            //};
            //RedisHelper.Add("user:1", user, DateTime.Now + new TimeSpan(1, 0, 0));

            User user = RedisHelper.Get<User>("user:1");

            Console.WriteLine(user.ToString());
            string st="";
            for (int i = 0; i < 1024; i++)
            {
                st += "a";
            }
            RedisHelper.Add("st",st,new TimeSpan(1,0,0));
            while (true)
            {
                Console.ReadLine();
            }
        }


    }

    class User
    {
        public string UserToken { get; set; }
        public int Age { get; set; }
        public string Password { get; set; }

        public override string ToString()
        {
            string s = "UserToken:" + UserToken;
            s += " Password:" + Password;
            s += " Age:" + Age;
            return s;
        }
    }
