Asp.Net Session 在 ashx 文件中为空
问题描述：
我正在尝试访问 Asp.Net ashx 处理程序中的 Session 变量，如下所示.
I am trying to access the Session variable in Asp.Net ashx handler as shown below.
public void ProcessRequest (HttpContext context) {
context.Session["VariableName"] = Id;
}
但是 context.Session 在上述方法中总是 Null.如何访问 ashx 文件中的 Session 对象?
But the context.Session is always Null inside the above method. How do I access Session objects in ashx file?
答
您必须实施"任一IRequiresSessionState 或 IReadOnlySessionState，前者提供对会话的完全访问权限，后者提供只读访问权限.
You have to "implement" either IRequiresSessionState or IReadOnlySessionState, with former providing full access to session, and the latter providing read-only access.
我在这里引用实现"是因为这两个是所谓的标记接口"，这意味着他们没有成员.
I'm quoting "implement" here because these two are so-called "marker interfaces", which means they have no members.
