.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> |
登陆的方法贴出一部分代码,仅供参考
