验证视图状态MAC失败

Question

可能重复:
设置ViewStateUserKey为我提供了"验证viewstate MAC failed"错误

我已经在StackOverflow上应用了帖子的解决方案但是他们没有解决我的问题.

问题的细节是:

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.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

我已经尝试将它放在web.config中:

<pages validateRequest="false" enableEventValidation="false" viewStateEncryptionMode ="Never">

Answer 1

我刚才问了一个类似的问题.你看到这篇文章吗？帮我解决这个错误的另一件事是设置了一个machineKey.有关问题和设置计算机密钥,请参阅此Microsoft页面.

Answer 2

我今天开始遇到这个问题.

长话短说 - 我从类似的页面复制了一些表单代码而忘记更改表单操作:

<form id="Form1" action="search.aspx" method="post" runat="server">

</form>

results.aspx上的表单应该是:

<form id="Form1" action="results.aspx" method="post" runat="server">

</form>

在深入研究配置和其他设置之前,我会建议其他任何人检查这个以及任何继承值.
