![ADFS 依赖方](https://linux22.com/image/519984/ADFS%20%E4%BE%9D%E8%B5%96%E6%96%B9.png)
我正在尝试设置 Active Directory 联合身份验证服务依赖方,但出现以下错误。
我已尝试修改该页面以允许<pages validateRequest="false">
web.config,但并没有什么区别。
有人可以帮我吗?
‘/test’ 应用程序中的服务器错误。
A potentially dangerous Request.Form value was detected from the client (wresult="<t:RequestSecurityTo...").
Description: Request Validation has detected a potentially dangerous client input value, and processing of the request has been aborted. This value may indicate an attempt to compromise the security of your application, such as a cross-site scripting attack. To allow pages to override application request validation settings, set the requestValidationMode attribute in the httpRuntime configuration section to requestValidationMode="2.0". Example: <httpRuntime requestValidationMode="2.0" />. After setting this value, you can then disable request validation by setting validateRequest="false" in the Page directive or in the <pages> configuration section. However, it is strongly recommended that your application explicitly check all inputs in this case. For more information, see http://go.microsoft.com/fwlink/?LinkId=153133.

我相信你现在(从 .Net 4.0 开始)还需要在 web.config 中将请求验证模式设置为 2.0。像这样:
<system.web>
<httpRuntime requestValidationMode="2.0" />
<pages validateRequest="false" />
