设置ViewStateUserKey让我一个＆QUOT; MAC视图状态验证不合格＆QUOT;错误 [英] Setting ViewStateUserKey gives me a "Validation of viewstate MAC failed" error

问题描述

我在的BasePage 类，我所有的ASPX页面从推导出以下内容：

I have the following in my BasePage class which all my ASPX pages derive from:

protected override void OnInit(EventArgs e)
{
    base.OnInit(e);
    ViewStateUserKey = Session.SessionID;
}

我也有的Web.config A 的machineKey 设置。我不认为这个错误是因为Web场，因为出现这种情况我开发的机器上了。

I also have a machineKey set in Web.config. I don't think this error is because of a web farm because this happens on my dev machine too.

我的主机现在已经升级到.NET 3.5 SP1。此更新后，每次我与 ViewStateUserKey 设置上面，我不断地得到编译验证视图状态MAC失败错误在每次回发。

My host has now upgraded to .NET 3.5 SP1. After this update, everytime I compile with the ViewStateUserKey setting above, I constantly get the "Validation of viewstate MAC failed" error on every postback.

我在做什么错在这里？这是设置甚至必要再与最新的框架更新？

What am I doing wrong here? Is this setting even necessary anymore with the latest framework update?

推荐答案

确定 - 林晚了一年的谈话 - 但这是如何正确的答案？这仅适用于通过验证的用户的情况下，并使用 ViewStateUserKey 作为用户名是一个容易得多比会话ID GUID猜测。

OK - Im a year late to the conversation - but how is this the correct answer? This applies only in the case of authenticated users and using the ViewStateUserKey as the username is a lot easier to guess than a session id GUID.

顺便说一句，如果你想'修复'的code向上顶，使用Session ID，但你必须设置一个会话变量，以使会话ID更改每次停下来。防爆。
会话[任何东西] = DateTime.Now

BTW if you want to 'fix' the code up top, use the Session ID, however you must set a session variable in order for the session id to stop from changing every time. Ex. Session["Anything"] = DateTime.Now

ViewStateUserKey = Session.SessionID;

这当然是假设你要使用会话，否则，你需要一些其他的键使用，比如用户名或任何其他GUID保存在cookie中。

This of course is assuming you are going to use sessions, otherwise you need some other key to use such as the username or any other guid kept in a cookie.
