.net MVC中使用forms验证,供大家参考,具体内容如下
文件夹的分部是这样子的
首先在Web.config中设置
authentication和authorization 节点

< system.web >
< authentication mode = "Forms" >
< forms loginUrl = "~/Login/Index" timeout = "2880" defaultUrl = "~/Home/Index" />
</ authentication >
< anonymousIdentification enabled = "true" />
< authorization >
< deny users = "?" /> <!--拒绝匿名访问-->
</ authorization >
< compilation debug = "true" targetFramework = "4.5" />
< httpRuntime targetFramework = "4.5" />
< httpModules >
< add name = "ApplicationInsightsWebTracking" type = "Microsoft.ApplicationInsights.Web.ApplicationInsightsHttpModule, Microsoft.AI.Web" />
</ httpModules >
</ system.web >

如果在Login文件夹还有不需要匿名访问,或者在LoginController中除了登陆还有方法可以匿名访问,
那么我们需要在加上这一个节点

<location path= "Login" > <!--这里的意思就是LoginController下的方法可以匿名访问-->
<system.web>
<authorization>
<allow users= "*" /> <!--允许匿名访问-->
</authorization>
</system.web>
</location>
