ServiceStack.Redis 使用

环境准备

• Redis (使用Windows版本做测试，运营环境建议使用Linux版本)
• ServiceStack.Redis-v3.00

在Windows上运行Redis服务器作开发和测试是很好的，但是在运营环境还是Linux版本靠谱，下面我们就先解压Redis到一个目录下：

运行redis-server.exe 看到如下Windows控制台：

上面我们可以看到Redis运行的端口是6372

我们先玩一下Redis的客户端控制台，在相同目录下运行redis-cli.exe会弹出另一个控制台程序，可以参考Try Redis tutorial开始你的交互之旅。

输入命令 set car.make “Ford” 添加了一个car.make为Key，Value是Ford的数据进入Redis，输入命令get car.make就可以取回Ford

下面我们进入正题，讲主角ServiceStack.Redis ：

首先创建一个控制台程序，然后解压缩ServiceStack.Redis-v3.00.zip ，然后添加下面的四个引用

• ServiceStack.Common
• ServiceStack.Interfaces
• ServiceStack.Redis
• ServiceStack.Text

我们下面来写些代码，创建一个Car类并存储几个实例到Redis，然后让一个对象5秒后过期，等待6秒钟后输出Car的实例数

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using ServiceStack.Redis; 
using System.Threading;

namespace RedisTutorial 
{ 
    class Program 
    { 
        static void Main(string[] args) 
        { 
            var redisClient = new RedisClient("localhost");

            using (var cars = redisClient.GetTypedClient<Car>()) 
            { 
                if (cars.GetAll().Count > 0) 
                    cars.DeleteAll();

                var dansFord = new Car 
                { 
                    Id = cars.GetNextSequence(), 
                    Title = "Dan's Ford", 
                    Make = new Make { Name = "Ford" }, 
                    Model = new Model { Name = "Fiesta" } 
                }; 
                var beccisFord = new Car 
                { 
                    Id = cars.GetNextSequence(), 
                    Title = "Becci's Ford", 
                    Make = new Make { Name = "Ford" }, 
                    Model = new Model { Name = "Focus" } 
                }; 
                var vauxhallAstra = new Car 
                { 
                    Id = cars.GetNextSequence(), 
                    Title = "Dans Vauxhall Astra", 
                    Make = new Make { Name = "Vauxhall" }, 
                    Model = new Model { Name = "Asta" } 
                }; 
                var vauxhallNova = new Car 
                { 
                    Id = cars.GetNextSequence(), 
                    Title = "Dans Vauxhall Nova", 
                    Make = new Make { Name = "Vauxhall" }, 
                    Model = new Model { Name = "Nova" } 
                };

                var carsToStore = new List<Car> { dansFord, beccisFord, vauxhallAstra, vauxhallNova }; 
                cars.StoreAll(carsToStore);

                Console.WriteLine("Redis Has-> " + cars.GetAll().Count + " cars");

                cars.ExpireAt(vauxhallAstra.Id, DateTime.Now.AddSeconds(5)); //Expire Vauxhall Astra in 5 seconds

                Thread.Sleep(6000); //Wait 6 seconds to prove we can expire our old Astra

                Console.WriteLine("Redis Has-> " + cars.GetAll().Count + " cars");

                //Get Cars out of Redis 
                var carsFromRedis = cars.GetAll().Where(car => car.Make.Name == "Ford");

                foreach (var car in carsFromRedis) 
                { 
                    Console.WriteLine("Redis Has a ->" + car.Title); 
                }

            } 
            Console.ReadLine(); 
        } 
    }

    public class Car 
    { 
        public long Id { get; set; } 
        public string Title { get; set; } 
        public string Description { get; set; } 
        public Make Make { get; set; } 
        public Model Model { get; set; } 
    }

    public class Make 
    { 
        public int Id { get; set; } 
        public string Name { get; set; } 
    }

    public class Model 
    { 
        public int Id { get; set; } 
        public Make Make { get; set; } 
        public string Name { get; set; } 
    }

}
