web開發 那些年基於Redis的Provider庫

  由於session基於本地cache，之前咱們本身寫分佈式緩存，或者數據庫存儲，或者cookie加密存儲，來保存用戶狀態信息，但較少的直接經過建立一個繼承 SessionStateStoreProviderBase 類，來實現自定義會話狀態存儲提供程序。但有ASP.NET官方的福利，咱們就不能放過。

  Microsoft.Web.RedisOutputCacheProvider，沒錯就是它，此庫底層用的正是StackExchange來訪問redis

  固然，不止MS寫了，這個也是能夠滴：https://github.com/alex-simonov/RedisAspNetProviders

Install-Package Microsoft.Web.RedisSessionStateProvider

  webconfig出現一小坨，若是用的是Azure的Redis，那你須要填一下host和accesskey，不然也沒啥好改的

<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>

　　接着咱們看看它能幹啥？

 

//Action Index中，就兩句，view直接輸出Model
Session["UserAgent"] = Request.UserAgent;
ViewData.Model = "訪問狀態已分佈式存儲session";

//而後咱們訪問另外一個About，而後直接輸出Session：@Model
//不出意料的出現了：Session:Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.94 Safari/537.36
//固然大家是看不到，我反正看到了，但看不到也不是重點
ViewData.Model = Session["UserAgent"];

　　重點來了，有圖有真相，分佈式Session完畢

    這麼屌，是否能搞OutputCacheProvider？搞搞不要錢

Install-Package Microsoft.Web.RedisOutputCacheProvider

　　依舊免費給的一大坨

<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();
}

　　固然訪問此頁面怎麼刷新都是同一個時間，但咱們要學會尋找重點

     雖然真相就在眼前
