Question

我有asp页面，我从查询字符串中获取值并存储在会话中。代码

username = Trim(Request.querystring("username"))
Session("login")=username
NewUserName=Session("login")

现在我想在Asp.vb页面中访问此NewUserName值 代码是（.aspx页面）

<script type="text/javascript" language="javascript">

var login = '<%= Session["NewUserName"].ToString(); %>';
Session("login")=Login;
alert(login);

</script>

代码是（.aspx.vb）

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load



Login = Session("login")
    If Session("login") Is Nothing Then
        Response.Redirect("../Default.aspx")
    End If
    Session("qid") = 0
End Sub

但是这会产生错误而不会访问该值。

您可以从asp.net页面访问内存中的Classic ASPSESSION的最简单的桥接器是：

在ASP端：输出会话的asp页面，例如调用它asp2netbridge.asp

<%
'Make sure it can be only called from local server '
if (request.servervariables("LOCAL_ADDR") = request.servervariables("REMOTE_ADDR")) then
    if (Request.QueryString("sessVar") <> "") then
        response.write Session(Request.QueryString("sessVar"))
    end if
end if
%>

在.net端，远程调用该asp页面。：

private static string GetAspSession(string sessionValue)
 {
    HttpWebRequest _myRequest = (HttpWebRequest)WebRequest.Create(new Uri("http://yourdomain.com/asp2netbridge.asp?sessVar=" + sessionValue));
    _myRequest.ContentType = "text/html";
    _myRequest.Credentials = CredentialCache.DefaultCredentials;
    if (_myRequest.CookieContainer == null)
        _myRequest.CookieContainer = new CookieContainer();
    foreach (string cookieKey in HttpContext.Current.Request.Cookies.Keys)
    {
        ' it is absolutely necessary to pass the ASPSESSIONID cookie or you'll start a new session ! '
        if (cookieKey.StartsWith("ASPSESSIONID")) {
            HttpCookie cookie = HttpContext.Current.Request.Cookies[cookieKey.ToString()];
            _myRequest.CookieContainer.Add(new Cookie(cookie.Name, cookie.Value, cookie.Path, string.IsNullOrEmpty(cookie.Domain)
                ? HttpContext.Current.Request.Url.Host
                : cookie.Domain));
        }
    }
    try
    {
        HttpWebResponse _myWebResponse = (HttpWebResponse)_myRequest.GetResponse();

        StreamReader sr = new StreamReader(_myWebResponse.GetResponseStream());
        return sr.ReadToEnd();
    }
    catch (WebException we)
    {
        return we.Message;
    }
}
