问题描述
我们有一个经典 ASP 网站，我们正在根据需要慢慢迁移到 ASP.NET.
We have a website in classic asp that we are slowly migrating to ASP.NET as necessary.
问题当然是经典的 asp 和 ASP.NET 是如何处理 Sessions 的.在花了最后几个小时研究网络之后，我发现了很多文章，但没有一篇比其他文章更突出.
The problem of course is how classic asp and ASP.NET handle Sessions. After spending the last few hours researching the web, I found many articles, but not one that stood out over the others.
是否有在经典 asp 和 asp.net 之间传输会话变量的最佳实践?安全性是必须的，非常感谢任何带有示例的解释.
Is there a best practice for transferring session variables from and to classic asp and asp.net? Security is a must and any explanation with examples is much appreciated.
推荐答案
将单个会话变量从经典 asp 传递到 .net 服务器端(对客户端隐藏会话值)的简单桥接器是这样的:
A simple bridge to pass a single session variable from classic asp to .net serverside (hiding your sessionvalue from the client), would be this:
在 ASP 端:输出会话的 asp 页面，例如调用它.asp2netbridge.asp
On the ASP end: An asp page to output your session, call it e.g. 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.:
On the .net end, a remote call to that asp page. :
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 will 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;
}
}
