跨站点共享Session解决方案、单点登录解决方案(.NET 2.0版本)
摘要:我们在进行Web开发时经常会用到Session,用它去标识不同的会话,那么涉及到跨站点的时候如何实现Session共享呢?…

4、编译项目,生成ShareSession.dll

5、把ShareSession.dll引入Web Server 1上的应用程序中,同时在Web.config文件中增加配置字节

代码如下:

<!-- Session信息序列化后保存路径 -->
    <add key="ShareSessionPath" value="C:\ShareSession\"/>

6、在Web Server 1上的应用程序中新建一个页面,功能是初始化Session,然后把Session信息序列化,代码如下:

前台代码:

<%...@ Page Language="C#" AutoEventWireup="true" CodeFile="ShareSession.aspx.cs" Inherits="Front_Test_ShareSession" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
  <title>Session共享</title>
</head>
<body>
  <form id="form1" runat="server">
    <div>
      <asp:Label ID="lHttp_Cookie" runat="server" Text=""></asp:Label>
      <a href="http://localhost:5000/Front/Test/ShareSession.aspx?AUTH_GUID=<%=AUTH_GUID %>">Go Other Web Site(port:5000)</a>
    </div>
  </form>
</body>
</html>

后台代码:

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

public partial class Front_Test_ShareSession : System.Web.UI.Page
...{
  public string AUTH_GUID = "";

protected void Page_Load(object sender, EventArgs e)
  ...{
    Session.Clear();
    Session.Abandon();
    Session.Add("USER_ID", "2002");
    Session.Add("USER_NAME", "Xiaojun Liu");

ShareSession.ShareSessionFormatter.Serialize(ShareSession.ShareSessionFormatter.FormatterType.Soap);
    AUTH_GUID = Session["AUTH_GUID"].ToString();    
  }
}

7、在Web Server 2上进行第5步操作

8、在Web Server 2上的应用程序中新建一个页面,功能是反序列化,还原Session,同时读取Session信息进行测试,代码如下:

前台代码:

<%...@ Page Language="C#" AutoEventWireup="true" CodeFile="ShareSession.aspx.cs" Inherits="Front_Test_ShareSession" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
  <title>Session共享</title>
</head>
<body>
  <form id="form1" runat="server">
    <div>
      <asp:Label ID="lHttp_Cookie" runat="server" Text=""></asp:Label>
    </div>
  </form>
</body>
</html>

后台代码:

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

public partial class Front_Test_ShareSession : System.Web.UI.Page
...{
  protected void Page_Load(object sender, EventArgs e)
  ...{
    string guid = Request.Params["AUTH_GUID"].ToString();
    ShareSession.ShareSessionFormatter.Deserialize(ShareSession.ShareSessionFormatter.FormatterType.Soap,guid);

Response.Write("USER_ID = "+Session["USER_ID"].ToString()+"<br />");
    Response.Write("USER_NAME = "+Session["USER_NAME"].ToString()+"<br />");
    Response.Write("AUTH_GUID = " + Session["AUTH_GUID"].ToString() + "<br />");
  }
}

此例子只是提供了一种解决思路,在应用过程中应根据项目不同进行调整及详细设计。
