允许电子邮件和用户名进行身份验证

我使用ASP.Net Identity 2.1创建了两个项目（MVC 5和Web API），我无法找到如何同时使用电子邮件和用户名进行身份验证（一个名为Admin must使用用户名和公共区域必须使用电子邮件地址进行身份验证）。允许电子邮件和用户名进行身份验证

问题是，只有一种身份验证方法，它不允许您指定是否要与电子邮件地址或用户名进行比较。

SignInHelper.PasswordSignIn

我该怎么做才能做到这一点？

SignInManager你不与它的帮助，你需要使用UserManager，多一点暗中捣鬼（这是专业术语！）：

这是我有这样的场景：

var unauthUserByUsername = await userManager.FindByNameAsync(command.UserName); 
var unauthUserByEmail = await userManager.FindByEmailAsync(command.UserName); 

var unauthenticatedUser = unauthUserByUsername ?? unauthUserByEmail; 
if (unauthenticatedUser == null) 
{ 
    logger.Warn("User {0} is trying to login but username is not correct", command.UserName); 
    return View(); // stop processing 
} 

var loggedInUser = await userManager.FindAsync(unauthenticatedUser.UserName, command.Password); 
if (loggedInUser == null) 
{ 
    // username is correct, but password is not correct 
    logger.Warn("User {0} is trying to login with incorrect password", command.UserName); 
    await userManager.AccessFailedAsync(unauthenticatedUser.Id); 
    return View(); // stop processing 
} 

// Ok, from now on we have user who provided correct username and password. 

// and because correct username/password was given, we reset count for incorrect logins. 
await userManager.ResetAccessFailedCountAsync(loggedInUser.Id); 

if (!loggedInUser.EmailConfirmed) 
{ 
    logger.Warn("User {0} is trying to login, entering correct login details, but email is not confirmed yet.", command.UserName); 
    return View("Please confirm your email"); // stop processing 
} 

if (await userManager.IsLockedOutAsync(loggedInUser.Id)) 
{ 
    // when user is locked, but provide correct credentials, show them the lockout message 
    logger.Warn("User {0} is locked out and trying to login", command.UserName); 
    return View("Your account is locked"); 
} 

logger.Info("User {0} is logged in", loggedInUser.UserName); 

// actually sign-in. 
var authenticationManager = HttpContext.Current.GetOwinContext().Authentication; 
await userManager.SignInAsync(authenticationManager, loggedInUser, false);

这会检查用户是否确认了电子邮件，如果用户被锁定并且在一定次数的尝试后锁定用户（考虑到启用了所有其他锁定设置）。

这样既允许

var userEmail = await UserManager.FindByEmailAsync(model.Login); 

      if (userEmail == null) 
      { 
       var user = await UserManager.FindByNameAsync(model.Login); 
       if (user == null) 
       { 
        model.Login = ""; 
       } 

      } 
      else 
      { 
       model.Login = userEmail.UserName; 
      } 

var result = await SignInManager.PasswordSignInAsync(model.Login, model.Password, model.RememberMe, shouldLockout: false);
