使用Azure Redis Cache

通过上一篇博客《Redis Cache 简介》我们已经简单了解了Azure Redis Cache，这里就不过多赘述了。

1、创建Redis Cache

创建Redis Cache之前，我们首先要登录到 Azure Portal上，点击 New, Data + Storage, Redis Cache。

这里有一点需要说明一下，由于国内Azure目前不支持New Portal，因此国内的Azure订阅只能通过Powershell创建Redis Cache

#弹出界面输入用户名密码
Login-AzureRmAccount
#获取当前订阅名称
Get-AzureRmSubscription| Sort SubscriptionName|Select SubscriptionName
#选择当前订阅
Select-AzureRmSubscription -SubscriptionName  {SubscriptionName}
#在日本西部创建资源组
New-AzureRmResourceGroup -Name {ResourceGroupName} -Location "Japan West"
#在日本西部创建256MB的Redis Cache，服务级别为Basic
New-AzureRmRedisCache -ResourceGroupName {ResourceGroupName} -Name {RedisCacheName} -Location "Japan West" -Sku Basic -Size C0
#查看已经创建好的Redis Cache
Get-AzureRmRedisCache

 2、使用Redis Cache

创建一个Web Application，打开NuGet控制台输入：Install-Package StackExchange.Redis或者Install-Package StackExchange.Redis.StrongName，添加对程序集的引用。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using StackExchange.Redis;
using System.Net;

namespace AspNet5_Owin
{
    public class RedisManager
    {
        private static Lazy<ConnectionMultiplexer> lazyConnection = new Lazy<ConnectionMultiplexer>(() =>
        {
            ConfigurationOptions opt = new ConfigurationOptions
            {
                Ssl = true,
                AbortOnConnectFail = false,
                Password = "{Redis Cache Keys}"
            };
            opt.EndPoints.Add(new DnsEndPoint("{Host Name}", {Ssl Port}));
            return ConnectionMultiplexer.Connect(opt);
        });

        public static ConnectionMultiplexer Connection
        {
            get
            {
                return lazyConnection.Value;
            }
        }

        private static IDatabase cache = Connection.GetDatabase();

        public static void CacheSet(string key, string value)
        {
            cache.StringSet(key, value, TimeSpan.FromSeconds(10));
        }

        public static string CacheGet(string key)
        {
            return cache.StringGet(key);
        }

    }
}

将字符串添加到Redis Cache中并取回

//将字符串存储到Redis Cache中
RedisManager.CacheSet("name", "zhangsan");
//将字符串从Redis Cache中取回
string name = RedisManager.CacheGet("name");

将对象添加到Redis Cache中并取回

[Serializable]
class Employee
{
    public int Id { get; set; }
    public string Name { get; set; }

    public Employee(int EmployeeId, string Name)
    {
        this.Id = EmployeeId;
        this.Name = Name;
    }
}

RedisManager.CacheSet("employee", JsonConvert.SerializeObject(new Employee(25, "Clayton Gragg")))
Employee employee = JsonConvert.DeserializeObject<Employee>(RedisManager.CacheGet("employee"))
