问题描述

你好

我在我的本地系统上托管了一个网站。但它会抛出以下错误。



验证视图状态MAC失败。如果此应用程序由Web场或群集托管，请确保< machinekey> configuration指定相同的validationKey和验证算法。 AutoGenerate不能在群集中使用。



我在web.config中做了如下更改

仍然得到同样的错误。请帮帮我

解决方案

< blockquote>关闭ViewState MAC是一个非常糟糕的主意，从.NET 4.5.2开始不再支持：

Microsoft发布了一篇可能有用的知识库文章：

解决视图状态消息验证代码（MAC）错误 [ ^ ]

hello
i have hosted a website on my local system. but it throws following error.

Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machinekey> configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster.

for that i made changes in web.config as follows

解决方案

Turning off ViewState MAC is a very bad idea, and is no longer supported as of .NET 4.5.2:
http://blogs.msdn.com/b/webdev/archive/2014/05/07/asp-net-4-5-2-and-enableviewstatemac.aspx[^]

Microsoft have published a knowledgebase article which might help:
Resolving view state message authentication code (MAC) errors[^]

这篇关于验证视图状态MAC失败。如果此应用程序由Web场或群集托管，请确保&lt; machineKey&gt;配置指定相同的validationKey和验证算法....的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
