web开发 那些年基于Redis的Provider库

  因为session基于本地cache，以前我们自己写分布式缓存，或者数据库存储，或者cookie加密存储，来保存用户状态信息，但较少的直接通过创建一个继承 SessionStateStoreProviderBase 类，来实现自定义会话状态存储提供程序。但有ASP.NET官方的福利，我们就不能放过。

  Microsoft.Web.RedisOutputCacheProvider，没错就是它，此库底层用的正是StackExchange来访问redis

  当然，不止MS写了，这个也是可以滴：https://github.com/alex-simonov/RedisAspNetProviders

  研究内部实现可参考其下

  天色尚未晚 媳妇还未还，还有时间 干点正事吧...

Install-Package Microsoft.Web.RedisSessionStateProvider

  webconfig出现一小坨，如果用的是Azure的Redis，那你需要填一下host和accesskey，否则也没啥好改的

<sessionState mode="Custom" customProvider="MySessionStateStore">
      <providers>
        <!-- For more details check https://github.com/Azure/aspnet-redis-providers/wiki -->
        <!-- Either use 'connectionString' OR 'settingsClassName' and 'settingsMethodName' OR use 'host','port','accessKey','ssl','connectionTimeoutInMilliseconds' and 'operationTimeoutInMilliseconds'. -->
        <!-- 'throwOnError','retryTimeoutInMilliseconds','databaseId' and 'applicationName' can be used with both options. -->
        <!--
          <add name="MySessionStateStore" 
            host = "127.0.0.1" [String]
            port = "" [number]
            accessKey = "" [String]
            ssl = "false" [true|false]
            throwOnError = "true" [true|false]
            retryTimeoutInMilliseconds = "5000" [number]
            databaseId = "0" [number]
            applicationName = "" [String]
            connectionTimeoutInMilliseconds = "5000" [number]
            operationTimeoutInMilliseconds = "1000" [number]
            connectionString = "<Valid StackExchange.Redis connection string>" [String]
            settingsClassName = "<Assembly qualified class name that contains settings method specified below. Which basically return 'connectionString' value>" [String]
            settingsMethodName = "<Settings method should be defined in settingsClass. It should be public, static, does not take any parameters and should have a return type of 'String', which is basically 'connectionString' value.>" [String]
            loggingClassName = "<Assembly qualified class name that contains logging method specified below>" [String]
            loggingMethodName = "<Logging method should be defined in loggingClass. It should be public, static, does not take any parameters and should have a return type of System.IO.TextWriter.>" [String]
          />
        -->
        <add name="MySessionStateStore" type="Microsoft.Web.Redis.RedisSessionStateProvider" connectionString="127.0.0.1:6379,allowadmin=true" accessKey="" ssl="true" />
      </providers>
    </sessionState>

　　接着我们看看它能干啥？

//Action Index中，就两句，view直接输出Model
Session["UserAgent"] = Request.UserAgent;
ViewData.Model = "访问状态已分布式存储session";

//然后我们访问另一个About，然后直接输出Session：@Model
//不出意料的出现了：Session:Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.94 Safari/537.36
//当然你们是看不到，我反正看到了，但看不到也不是重点
ViewData.Model = Session["UserAgent"];

　　重点来了，有图有真相，分布式Session完毕

    这么屌，是否能搞OutputCacheProvider？搞搞不要钱

Install-Package Microsoft.Web.RedisOutputCacheProvider

　　依旧免费给的一大坨

<caching>
      <outputCache defaultProvider="MyRedisOutputCache">
        <providers>
          <!-- For more details check https://github.com/Azure/aspnet-redis-providers/wiki -->
          <!-- Either use 'connectionString' OR 'settingsClassName' and 'settingsMethodName' OR use 'host','port','accessKey','ssl','connectionTimeoutInMilliseconds' and 'operationTimeoutInMilliseconds'. -->
          <!-- 'databaseId' and 'applicationName' can be used with both options. -->
          <!--
          <add name="MyRedisOutputCache" 
            host = "127.0.0.1" [String]
            port = "" [number]
            accessKey = "" [String]
            ssl = "false" [true|false]
            databaseId = "0" [number]
            applicationName = "" [String]
            connectionTimeoutInMilliseconds = "5000" [number]
            operationTimeoutInMilliseconds = "1000" [number]
            connectionString = "<Valid StackExchange.Redis connection string>" [String]
            settingsClassName = "<Assembly qualified class name that contains settings method specified below. Which basically return 'connectionString' value>" [String]
            settingsMethodName = "<Settings method should be defined in settingsClass. It should be public, static, does not take any parameters and should have a return type of 'String', which is basically 'connectionString' value.>" [String]
            loggingClassName = "<Assembly qualified class name that contains logging method specified below>" [String]
            loggingMethodName = "<Logging method should be defined in loggingClass. It should be public, static, does not take any parameters and should have a return type of System.IO.TextWriter.>" [String]
          />
          -->
          <add name="MyRedisOutputCache" type="Microsoft.Web.Redis.RedisOutputCacheProvider" connectionString="127.0.0.1:6379,allowadmin=true" accessKey="" ssl="true" />
        </providers>
      </outputCache>
    </caching>

　　↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓

[OutputCache(Duration = 60, VaryByParam = "*")]
public ActionResult RedisCacheIndex()
{
  ViewData.Model = DateTime.Now.ToString();
  return View();
}

　　当然访问此页面怎么刷新都是同一个时间，但我们要学会寻找重点

     虽然真相就在眼前
