WindowsAzure 之AppFabricCache

WindowsAzure 之AppFabricCache

1.使用 windows azure平台账号(Live ID)登陆 https://windows.azure.com/

2.创建AppFabricCache

点击 ”Service Bus, Access Control&Caching” 导航

选择AppFabric 下的 Cache 节点，点击New按钮

输入cache的命名空间，选择区域，点击Create Namespace

系统将显示cache 正在activing ,大概需要15分钟左右才能ready:

查看客户端配置，这里的your access token 和 yournamespace name将在下面的实验中用到,千万不要泄漏这两项信息，因为有了这两项信息就可以访问（读写）cache 了，到时可是要付美元的哦：

3.如何在程序中使用AppFabric Cache

a.Web.config 配置如下(注意替换YourNamespaceName和 YourAccessToken)：

<?xml version="1.0"?>

<!--
  For more information on how to configure your ASP.NET application, please visit
  http://go.microsoft.com/fwlink/?LinkId=169433
  -->

<configuration>
  <configSections>
    <!-- Append below entry to configSections. Do not overwrite the full section. -->
    <section name="dataCacheClients" type="Microsoft.ApplicationServer.Caching.DataCacheClientsSection, Microsoft.ApplicationServer.Caching.Core"
             allowLocation="true" allowDefinition="Everywhere"/>
  </configSections>

  <!-- Cache exposes one endpoint: one simple-->
  <dataCacheClients>

    <dataCacheClient name="default">
      <hosts>
        <host name="YourNamespaceName.cache.windows.net" cachePort="22233" />
      </hosts>

      <securityProperties mode="Message">
        <messageSecurity
          authorizationInfo="YourAccessToken">
        </messageSecurity>
      </securityProperties>
    </dataCacheClient>

    <dataCacheClient name="SslEndpoint">
      <hosts>
        <host name="YourNamespaceName.cache.windows.net" cachePort="22243" />
      </hosts>

      <securityProperties mode="Message" sslEnabled="true">
        <messageSecurity
          authorizationInfo="YourAccessToken">
        </messageSecurity>
      </securityProperties>
    </dataCacheClient>

  </dataCacheClients>

  <system.diagnostics>
    <trace>
      <listeners>
        <add type="Microsoft.WindowsAzure.Diagnostics.DiagnosticMonitorTraceListener, Microsoft.WindowsAzure.Diagnostics, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
          name="AzureDiagnostics">
          <filter type="" />
        </add>
      </listeners>
    </trace>
  </system.diagnostics>
  <connectionStrings>
    <!--<add name="ApplicationServices"
         connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\aspnetdb.mdf;User Instance=true"
         providerName="System.Data.SqlClient" />-->
  </connectionStrings>

  <system.web>
    <compilation debug="true" targetFramework="4.0" />

    <authentication mode="Forms">
      <forms loginUrl="~/Account/Login.aspx" timeout="2880" />
    </authentication>

    <membership>
      <providers>
        <clear/>
        <add name="AspNetSqlMembershipProvider" type="System.Web.Security.SqlMembershipProvider" connectionStringName="ApplicationServices"
             enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="false" requiresUniqueEmail="false"
             maxInvalidPasswordAttempts="5" minRequiredPasswordLength="6" minRequiredNonalphanumericCharacters="0" passwordAttemptWindow="10"
             applicationName="/" />
      </providers>
    </membership>

    <profile>
      <providers>
        <clear/>
        <add name="AspNetSqlProfileProvider" type="System.Web.Profile.SqlProfileProvider" connectionStringName="ApplicationServices" applicationName="/"/>
      </providers>
    </profile>

    <roleManager enabled="false">
      <providers>
        <clear/>
        <add name="AspNetSqlRoleProvider" type="System.Web.Security.SqlRoleProvider" connectionStringName="ApplicationServices" applicationName="/" />
        <add name="AspNetWindowsTokenRoleProvider" type="System.Web.Security.WindowsTokenRoleProvider" applicationName="/" />
      </providers>
    </roleManager>

    <!-- If session state needs to be saved in AppFabric Caching service, add the following to web.config inside system.web. If ssl is required, then change dataCacheClientName to "SslEndpoint". -->
    <sessionState mode="Custom" customProvider="AppFabricCacheSessionStoreProvider">
      <providers>
        <add name="AppFabricCacheSessionStoreProvider"
             type="Microsoft.Web.DistributedCache.DistributedCacheSessionStateStoreProvider, Microsoft.Web.DistributedCache"
             cacheName="default"
             useBlobMode="true"
             dataCacheClientName="SslEndpoint" />
      </providers>
    </sessionState>

    <!-- If output cache content needs to be saved in AppFabric Caching service, add the following to web.config inside system.web. -->
    <caching>
      <outputCache defaultProvider="DistributedCache">
        <providers>
          <add name="DistributedCache"
               type="Microsoft.Web.DistributedCache.DistributedCacheOutputCacheProvider, Microsoft.Web.DistributedCache"
               cacheName="default"
               dataCacheClientName="default" />
        </providers>
      </outputCache>
    </caching>

  </system.web>

  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>
  </system.webServer>
</configuration>

b. 创建一个类，用于模拟cache要存的信息：

 using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace WebRole1
{
    public class Person
    {
        public string ID;
        public string Name = string.Empty;
        public int Age = 25;
    }
}

c. 用代码存取cache：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using Microsoft.WindowsAzure;
using Microsoft.WindowsAzure.StorageClient;
using Microsoft.WindowsAzure.ServiceRuntime;
using System.Threading;
using System.Data.SqlClient;
using System.Data;
using Microsoft.ApplicationServer.Caching;

namespace WebRole1
{
    public partial class TestCache : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!this.IsPostBack)
            {
                Session["101"] = new Person { ID = "101", Name = "Abraham Cheng", Age = 26 };
                using (DataCacheFactory dataCacheFactory = new DataCacheFactory())
                {
                    DataCache dataCache = dataCacheFactory.GetDefaultCache();
                    Person person = new Person { ID = "101", Name = "Abraham Cheng", Age = 26 };
                    dataCache.Put(person.ID.ToString(), person);
                }

                using (DataCacheFactory dataCacheFactory = new DataCacheFactory())
                {
                    DataCache dataCache = dataCacheFactory.GetDefaultCache();
                    Person person = (Person)dataCache.Get("101");
                    this.Response.Write("Get the person which ID is 101 from the cache:" + person.Name);
                }
            }
        }
    }
}

d. 将程序部署到云端(注意cache本地调试可能会有问题，本地无法解析cache的地址)，效果如下

注: 如何创建并部署云应用程序，请参考http://blog.csdn.net/farawayplace613/article/details/6933915
