WindowsAzure 之AppFabricCache

                                               WindowsAzure 之AppFabricCache

1.   使用 windows azure平台帳號(Live ID)登陸 https://windows.azure.com/

2.   建立AppFabricCache

點擊 ”Service Bus, Access Control&Caching” 導航

            選擇AppFabric  下的 Cache 節點，點擊New按鈕

輸入cache的命名空間，選擇地區，點擊Create Namespace

系統將顯示cache 正在activing ,大概需要15分鐘左右才能ready:

查看用戶端配置，這裡的your access token 和 yournamespace name將在下面的實驗中用到,千萬不要泄漏這兩項資訊，因為有了這兩項資訊就可以訪問（讀寫）cache 了，到時可是要付美元的哦：

3.   如何在程式中使用AppFabric Cache

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

<?xml version="1.0"?><!--  For more information on how to configure your ASP.NET application, please visithttp://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.  建立一個類，用於類比cache要存的資訊： 

 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.  用代碼存取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.  將程式部署到雲端(注意cache本地調試可能會有問題，本地無法解析cache的地址)，效果如下
