错误：验证视图状态MAC失败。 [英] Error : Validation of viewstate MAC failed.

问题描述

你好先生我在子域名主办一个网站



demoweb.asgraphicsnext.com



当我在我的网站出现错误10分钟后打开这个网站







'/'应用程序中的服务器错误。





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。



请给我一些解决方法如何修复此错误。

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.

推荐答案

您可以使用各种在线工具生成机器密钥，并将该代码放在<的System.Web> web.config的元素



例如

Hi,

you can generate machine key using various online tools and place that code inside <system.web> element of web.config

for example

<system.web>
<machineKey 
  validationKey="9D5525FFA8AB85DEB5CB3C002E2E07B4E5CB7A420CF795C3B53392FB1EC0DFC3D589A903634AD5D02F9A61990703D05509D17AA568EB3405C9373C11CD3097CC"
  decryptionKey="A7CB97DA5CA1F2DDD782476D821EDC3BE87C6ABA2F23E728348B06E13DD77694"
  validation="SHA1" decryption="AES"/>
</system.web>

generate a <machineKey> element and update in web config file and your issue will be solved

You can generate machine keys from the IIS manager

The value is stored locally in the web.config of that application something like

<?xml version="1.0" encoding="UTF-8"?> 
<configuration> 
    <system.web> 
        <machineKey decryptionKey="F6722806843145965513817CEBDECBB1F94808E4A6C0B2F2,IsolateApps" validationKey="C551753B0325187D1759B4FB055B44F7C5077B016C02AF674E8DE69351B69FEFD045A267308AA2DAB81B69919402D7886A6E986473EEEC9556A9003357F5ED45,IsolateApps" /> 
    </system.web> 
</configuration>
