在原有的asp程序中用asp.net添加功能模块,共享SESSIONs是一个难点,下面介绍一种较为简洁的方法,可以在asp和asp.net中共享session会话。 登录页面使用C#重新创建,在成功登录后执行语句: Response.Write("<script language='javascript'>window.open('ASPXTOASP.aspx','new');</script>"); 打开aspxtoasp.aspx页面,action设为aspxtoasp.asp,即可将session值post到asp页面,因为是单向传递,不用在其他页面重复执行动作,经测试,传递成功! Aspxtoasp.aspx代码如下: <script language="C#" runat="server"> Response.Write( "<form name=t id=t action=ASPXTOASP.asp method=post>" ); foreach(object it in Session.Contents) { Response.Write("<input type=hidden name=" + it.ToString()); Response.Write( " value=" + Session[it.ToString()].ToString() + " >"); } Response.Write("</FORM>"); Response.Write("<script>t.submit();</script>"); </script> Aspxtoasp.asp代码如下: <% for i=1 to Request.Form.Count Session(Request.Form.Key(i))=Request.Form(i) next Response.End %> <script language="JavaScript"> window.close(); </script> 这是一个老话题了,因为最近用的到,所以没办法又到处找资料。微软的网站上提供的是用数据库实现的,总觉得太麻烦,也有说直接使用的,但我没有试成功。我认为直接使用是不可能的。还有一种方法,就是通过几个页面转换,我使用的也是这个方法,通过总结搜索到的资料,整理后编写了几个页面来转换。主要是通过隐藏的input来实现的。具体方法如下: asp 转 asp.net 页面: 用一个asp页,把session信息写到input中,提交给asp.net页 trans.asp <% ’’----------测试数据-------- session("name")="srx" session("id")="1" session("sex")="f" session("pass")="asdfas" session("age")="23" session("weight")="131" ’’-------------------------- Response.Write("<form name=frm id=frm action=""asptoaspx.aspx"" method=post >") for each Item in Session.Contents Response.Write("<input type=hidden name=" & Item) Response.Write( " value=" & Session(item) & " >") next if len(Request.QueryString("Destpage")) >4 then Response.Write("<input type=hidden name=DestPage value=" & Request.querystring("DestPage") & ">") end if Response.Write("</FORM>") Response.Write("<scr" + "ipt>frm.submit();</scr" + "ipt>") %> asptoaspx.aspx <%@ Page language="c#" %> <script language=C# runat=server> private void Page_Load(object sender, System.EventArgs e) { Session.Timeout = 60; for(int i=0;i<Request.Form.Count;i++) { Session[Request.Form.GetKey(i)]=Request.Form[i].ToString(); } allsession(); //输出所有的Session,使用时可注释掉 try { if( Session["DestPage"].ToString().Length >4 ) { Server.Transfer(Session["DestPage"].ToString(),true); } } catch {} } private void allsession() { Response.Write ("There are " + Session.Contents.Count +" Session <I>var</I>iables<P>"); foreach(object obj in Session.Contents) { Response.Write("Session["+obj.ToString()+"] - "+Session[obj.ToString()].ToString()+"<br>");//输出所有的Session,使用时可注释掉 } } </script> asp.net 转 asp 页面: 用一个asp.net页,把session信息写到input中,提交给asp页 trans.aspx <%@ Page language="c#" %> <script language=C# runat=server> private void Page_Load(object sender, System.EventArgs e) { // ----------测试数据--------- Session["name"] = "srx"; Session["sex"]="F"; //---------------------------- Response.Write("<form name=frm id=frm action=aspxtoasp.asp method=post>"); foreach(object obj in Session.Contents) { Response.Write("<input type=hidden name=’"+obj.ToString()+"’"); Response.Write(" value = ’"+Session[obj.ToString()].ToString()+"’>"); } try { if(Request.QueryString["DestPage"].ToString().Length > 4 ) { Response.Write("<input type=hidden name=’DestPage’"); Response.Write(" value = ’"+Request.QueryString["DestPage"].ToString()+"’>"); } } catch{} Response.Write("</form>"); Response.Write("<scr"+"ipt language=’javascript’>frm.submit();</scr"+"ipt>"); } </script> aspxtoasp.asp <% for i=1 to Request.Form.Count Session(Request.Form.Key(i))=Request.Form(i) next if Len(Session("DestPage")) >4 then Response.Redirect(Session("DestPage")) end if ’----------输出所有的Session------------- call allsession() ’使用时注释掉此行代码即可 function allsession() Response.Write "There are " & Session.Contents.Count &" Session <I>var</I>iables<P>" Dim strName, iLoop For Each strName in Session.Contents’使用For Each循环察看Session.Contents If IsArray(Session(strName)) then ’如果Session变量是一个数组? ’循环打印数组的每一个元素 For iLoop = LBound(Session(strName)) to UBound(Session(strName)) Response.Write strName & "(" & iLoop & ") - " & _ Session(strName)(iLoop) & "<BR>" Next Else ’其他情况,就简单打印变量的值 Response.Write strName & " - " & Session.Contents(strName) & "<BR>" End If Next end function ’-------------------------------------------- %> |
