asp.net-mvc - Redis 的 ASP.NET 输出缓存提供程序不存储

Question

我不确定如何解决它，但我正在尝试通过 Redis 输出缓存提供程序实现 ASP.NET 输出缓存。

我们设置了 Redis 服务器(非 Azure)，我可以存储缓存以供一般使用。但是，当我尝试设置 ASP.NET 输出缓存时，它似乎没有将任何内容保存到缓存中!

我已经通过 Nuget 安装了 Microsoft.Web.RedisOutputCacheProvider。Web.Config 设置如下:

<caching>
      <outputCache defaultProvider="MyRedisOutputCache">
        <providers>
          <add name="MyRedisOutputCache" type="Microsoft.Web.Redis.RedisOutputCacheProvider" host="ServerName" port="6464" accessKey="PasswordToRedis" />
        </providers>
      </outputCache>
</caching>

MVC Controller 设置了 OutputCache 属性:

[OutputCache(Duration = 3600, VaryByParam = "*", Location = OutputCacheLocation.ServerAndClient)]
        public JsonResult GetLookupData()

当我检查 Redis 时，我没有看到任何 OutputCache 被存储。

我错过了什么吗？有没有办法调试它为什么不在缓存中存储任何内容？

好吧，这真的很傻。

当你通过 Nuget 安装 RedisOutputCacheProvider 时，你将在你的 app/web.config 中得到这个小 doco:

<!-- 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]
            redisSerializerType = "<Assembly qualified class name that implements Microsoft.Web.Redis.ISerializer>" [String]
          />

它表示“ssl”的默认值为 false。但是，仔细阅读代码本身，它实际上默认为 true。

因此将 ssl 显式设置为 false 已修复它。

哦，我不得不将 RedisOutputCacheProvider 降级到 1.7.5。

3.0.1 对我来说根本不起作用。
