Using forms in .net MVC Verification, for your reference, the specific content is as follows
The divisions of the folder are like this
First set it in Web.config
Authentication and authorization node
<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>
If there is no need for anonymous access in the Login folder, or there is a way to anonymously access the LoginController besides logging in,
then we need After adding this node
<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>
, a part of the code is posted for the login method, for reference only
public bool ValidateUser(LoginVO model)
{
string encodePassword = MD5(model.PassWord);//加密
string sql =
"select * from User_Users where (UserName=@UserName or JobNumber=@JobNumber) and PassWord=@PassWord";
var user = Context.Data.Query<UsersPO>(sql,
new {UserName = model.LoginName, JobNumber = model.LoginName, PassWord = encodePassword}).SingleOrDefault();
if (user == null) return false;
DateTime expiration = model.IsRememberLogin //是否记住密码
? DateTime.Now.AddDays(14)
: DateTime.Now.Add(FormsAuthentication.Timeout);
var ticket=new FormsAuthenticationTicket(
1,//指定版本号：可随意指定
user.UserName,//登录用户名：对应 Web.config 中 <allow users="Admin" … /> 的 users 属性
DateTime.Now, //发布时间
expiration,//失效时间
true,//是否为持久 Cookie
user.UserId.ToString(), //用户数据：可用 ((System.Web.Security.FormsIdentity)(HttpContext.Current.User.Identity)).Ticket.UserData 获取
FormsAuthentication.FormsCookiePath //指定 Cookie 为 Web.config 中 <forms path="/" … /> path 属性，不指定则默认为“/”
);
var encryptedTicket = FormsAuthentication.Encrypt(ticket);
if (HttpContext.Current.Request.Cookies[FormsAuthentication.FormsCookieName] != null)
{

}
var loginIdentify=new HttpCookie(FormsAuthentication.FormsCookieName);

}
