驗證失敗

可能重複：
Setting ViewStateUserKey gives me a 「Validation of viewstate MAC failed」 error 驗證失敗

我已經應用在計算器上的職位的解決方案，但他們並沒有對我的問題制定出。

問題的細節是：

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.

我已經試圖把這個在web.config：

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

您是否正在運行網絡農場？ – Steven 2011-04-13 10:20:13

非常奇怪，我也有類似的問題3天，現在我解決了它。 1.我已使表單認證和有SSL假 <形式defaultUrl = 「〜/」 loginUrl = 「〜/帳戶/的Login.aspx」 requireSSL = 「假」超時= 「2880」/> 2。但在我的httpcookies標籤中，我有requireSSL = true。由於在Site.Master.cs它使用cookie來設置ViewStateUserKey，它有問題 3.因此，我得到的錯誤。 4.我將其修改爲錯誤並重新啓動的Web應用程序，現在它很好。 – 2015-02-16 08:02:15

我問過類似的問題，前一陣子。你有see this post嗎？另一件幫助我解決這個錯誤的方法是設置一個machineKey。看到這個Microsoft Page about the problem and setting a Machine Key。

如果您有網上服務器場，則還應該確保站點上的IIS站點ID在服務器之間相匹配。不知何故，這個數字被合併到ViewState的加密中。 – 2014-04-02 19:02:19

今天我開始有這個問題。

長話短說 - 我複製了一些表格的代碼從類似的網頁，然後忘記變更表單動作：

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

</form>

上results.aspx的形式應該是：

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

</form>

我會建議任何人檢查這一點，還有任何繼承值之前深入到配置和其他設置。
