Question

最奇怪的事情。我正在切换到SDK v1.7和一个新的ACS，我成功登录后得到了这个奇怪的错误。它似乎与Azure缓存服务的SessionState提供程序有关。

我没有使用预览，但我使用的是SDK 1.7，而我正在使用启用了预览功能的Windows Azure帐户。

这就像在ACS /缓存服务SDK的深处内部的东西搞砸了。

这是我的缓存配置：

  <dataCacheClients>
    <dataCacheClient name="default">
      <tracing sinkType="DiagnosticSink" traceLevel="Verbose" />
      <hosts>
        <host name="[[newCacheNamespace]].cache.windows.net" cachePort="22233" />
      </hosts>
      <securityProperties mode="Message">
        <messageSecurity authorizationInfo="[[secret]]">
        </messageSecurity>
      </securityProperties>
    </dataCacheClient>
    <dataCacheClient name="SslEndpoint">
      <tracing sinkType="DiagnosticSink" traceLevel="Verbose" />
      <hosts>
        <host name="[[newCacheNamespace]].cache.windows.net" cachePort="22243" />
      </hosts>
      <securityProperties mode="Message" sslEnabled="true">
        <messageSecurity authorizationInfo="[[secret]]">
        </messageSecurity>
      </securityProperties>
    </dataCacheClient>
  </dataCacheClients>

这是我的会话状态提供程序配置：

<sessionState mode="Custom" customProvider="AppFabricCacheSessionStoreProvider">
  <providers>
    <add name="DefaultSessionProvider" type="System.Web.Providers.DefaultSessionStateProvider, System.Web.Providers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" connectionStringName="DefaultConnection" applicationName="/" />
    <add name="AppFabricCacheSessionStoreProvider" type="Microsoft.Web.DistributedCache.DistributedCacheSessionStateStoreProvider, Microsoft.Web.DistributedCache" cacheName="default" useBlobMode="true" dataCacheClientName="default" />
  </providers>
</sessionState>

以下是我得到的错误：

这是一个老问题，但将来有人可能会遇到这个问题。

修复方法是：

删除＆lt;主机＆GT;元件。
相反，添加此元素：

＆LT; autoDiscover isEnabled =“true”identifier =“[[newCacheNamespace] .cache.windows.net”/＆gt;

就是这样

使用旧配置的Windows Azure缓存服务
