我的网站每天都抛出以下异常,我找不到解决方案.
我在网上做了很少的研究,这是我到目前为止所做的.将以下选项添加到aspx将无法解决问题.

ValidateRequest=”false” EnableEventValidation=”false”
ViewStateEncryptionMode=”Never” EnableViewStateMac=”false”
此外,我的推荐网址是正确的网址,我不知道它如何重定向两个(相同)参数.我的推荐页面中没有这样的链接.请帮忙.

UPDATE
我通过从下面的链接压缩ViewState来修复错误
http://www.codeproject.com/Articles/14733/ViewState-Compression
并通过用此替换原始方法来修复Base-64 char数组错误的无效长度.
protected override object LoadPageStateFromPersistenceMedium()
{
string viewState = Request.Form["__VSTATE"];
viewState = viewState.Replace(" ","+");
int mod4 = viewState.Length % 4;
if (mod4 > 0)
{
viewState += new string('=',4 - mod4);
}
byte[] bytes = Convert.FromBase64String(viewState);
bytes = Compressor.Decompress(bytes);
LosFormatter formatter = new LosFormatter();
return formatter.Deserialize(Convert.ToBase64String(bytes));
}
谢谢大家的帮助:)
解决方法
我很抱歉,但是您的网站没有任何内容,您需要尽快重新启用EventValidations.
通过发送许多测试numbers with your ViewState trying to find your hash key,你看到的是an attempt to hack your site.
IP you give have a big list of activity the last few days
现在,可能导致此错误的替代方法是破坏ViewState.如果你有太大的ViewState,你可以compress it and split it.你也可以disable all the controls that not needed.你也可以添加log to see from inside what’s is going on right on a base page.
