asp.net-mvc-3 - 允许使用用户名或电子邮件地址登录

Question

如何修改标准的 ASP.NET MVC 登录页面以允许用户使用电子邮件地址或用户名登录？

Answer 1

+1 到 Sparkle，因为它看起来可行，但我找到了更简单的方法。

在 AccountModel.cs 中更改 Display 属性(只是登录页面上文本框的标签)

public class LogOnModel
{
    [Required]
    [Display(Name = "User name or Email Address")]
    public string UserName { get; set; }
    ...

在 AccountController.cs 中更改 LogOn 方法以查看用户名是否看起来像电子邮件地址，如果是，则尝试从电子邮件地址中找到用户名。

[HttpPost]
public ActionResult LogOn(LogOnModel model, string returnUrl)
{
    if (ModelState.IsValid)
    {
        // Can login by username or email address                
        MembershipUser user = null;
        string userName;

        if (model.UserName.Contains("@"))
        {
            // Could change model.userName from email to username but this will change form values
            // if login fails (wrong pwd) which will be confusing to users, so keep in sep username string
            userName = Membership.GetUserNameByEmail(model.UserName);
            if (!String.IsNullOrEmpty(userName))
            {
                user = Membership.GetUser(userName);
            }
        }
        else
        {
            user = Membership.GetUser(model.UserName);
            userName = model.UserName;
        }

        if (user != null && validateAndLogOnUser(userName, model.Password, model.RememberMe))
        {
            // Rest of standard login code here
