mvc實體框架：使用數據庫登錄

Question

我已經在Microsoft sql server express中創建了一個數據庫。我需要能夠登錄Mvc 2應用程序，使用我的數據庫（不是現有的AcountController意思MembershipService）

我只需要用我的數據庫替換MemeberAhipService。我該怎麼做（我首先使用實體​​框架代碼）。我不需要在visual studio中創建模型。我有usermodel，userContext：Db。我想我也需要知識庫。任何人都可以給我一個例子，告訴我的步驟？

您可以創建自己的MembershipService。

例子：

新MembershipService.cs（或任何你想要的）

 
public class MembershipService 
{ 
    public bool IsUserValid(string username, string password) 
    { 
     var db = new DatabaseContext(); 
     var user = db.GetUser(username, password); 
     // Or however you want to get your data, via Context or Repository 
     return (user != null); 
    } 
} 

新FormsClass.cs

 
public class FormService 
{ 
    public void SignIn(string username, List&ltstring> roles) 
    { 

      FormsAuthenticationTicket authTicket = new 
          FormsAuthenticationTicket(1,   // Version 
          username,        // Username 
          DateTime.Now,       // Creation 
          DateTime.Now.AddMinutes(30),   // Expiration 
          false,         // Persistent 
          string.Join(",", roles.ToArray()));  // Roles 

      string encTicket = FormsAuthentication.Encrypt(authTicket); 
      HttpContext.Current.Response.Cookies.Add(new HttpCookie(FormsAuthentication.FormsCookieName, encTicket)); 

      GenericIdentity id = new GenericIdentity(username); 
      HttpContext.Current.User = new GenericPrincipal(id, roles.ToArray()); 
    } 
} 

在Global.asax中：

 
     protected void Application_PostAuthenticateRequest(object sender, EventArgs e) 
     { 
      HttpCookie authCookie = HttpContext.Current.Request.Cookies[FormsAuthentication.FormsCookieName]; 
      if (authCookie != null) 
      { 
       string encTicket = authCookie.Value; 
       if (!String.IsNullOrEmpty(encTicket)) 
       { 
        FormsAuthenticationTicket ticket = FormsAuthentication.Decrypt(encTicket); 
        FormsIdentity id = (FormsIdentity)Context.User.Identity; 
        var roles = ticket.UserData.Split(",".ToCharArray(), StringSplitOptions.RemoveEmptyEntries); 

        GenericPrincipal prin = new GenericPrincipal(id, roles); 
        HttpContext.Current.User = prin; 

       } 
      } 

     }
