如何在 ASP.NET MVC 中更改用户的电子邮件地址

Question

我正在开发一个 ASP.NET MVC4 应用程序。我实际上希望能够更改用户的电子邮件地址。

修改电子邮件.cshtml

@model Project.Models.ModifyEmailModel

@using (Html.BeginForm("Manage", "Account")) {
@Html.AntiForgeryToken()

@Html.ValidationSummary(true)

<fieldset>
    <legend>Change Email Address</legend>
    <ol>
        <li>
            @Html.LabelFor(m => m.OldEmailAddress)
            @Html.EditorFor(m => m.OldEmailAddress)
            @Html.ValidationMessageFor(m => m.OldEmailAddress)
        </li>
        <li>
            @Html.LabelFor(m => m.NewEmailAddress)
            @Html.EditorFor(m => m.NewEmailAddress)
            @Html.ValidationMessageFor(m => m.NewEmailAddress)
        </li>
        <li>
            @Html.LabelFor(m => m.ConfirmEmailAddress)
            @Html.TextBoxFor(m => m.ConfirmEmailAddress)
            @Html.ValidationMessageFor(m => m.ConfirmEmailAddress)
        </li>
    </ol>
    <input type="submit" value="Changer l'addresse email" />
</fieldset>
}

@section Scripts {
    @Scripts.Render("~/bundles/jqueryval")
}

AccountModels.cs

    namespace Project.Models
{
    public class UsersContext : DbContext
    {
        public UsersContext()
            : base("DefaultConnection")
        {
        }

        public DbSet<UserProfile> UserProfiles { get; set; }

    }


    [Table("UserProfile")]
    public class UserProfile
    {
        [Key]
        [DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)]
        public int UserId { get; set; }
        public string UserName { get; set; }
        public string EmailId { get; set; }
        public string Details { get; set; }
    }


    public class ModifyEmailModel
    {
        [Required(ErrorMessage = "l'addresse email actuelle est requise")]
        [DataType(DataType.EmailAddress)]
        [Display(Name = "Addresse email actuelle")]
        public string OldEmailAddress { get; set; }

        [Required(ErrorMessage = "la nouvelle addresse email est requise")]
        [DataType(DataType.EmailAddress)]
        [Display(Name = "Nouvelle addresse email")]
        public string NewEmailAddress { get; set; }

        [DataType(DataType.EmailAddress)]
        [Display(Name = "Confirmer la nouvelle addresse mail")]
        [Compare("NewEmailAddress", ErrorMessage = "Le nouvelle addresse email et la confirmation de l'addresse email ne correspondent pas.")]
        public string ConfirmEmailAddress { get; set; }
    }




}

我不知道如何在 AccountController.cs 中实现该操作，请帮助！

Answer 1

我从您的描述中了解到，您需要一种操作方法来修改电子邮件地址。因此，您可以尝试以下方法，

[HttpPost]
public ActionResult Manage(ModifyEmailModel data)
{
    if(data.NewEmailAddress == data.ConfirmEmailAddress)
    {
        // db is your context instance
        var u = db.UserProfiles.Where(x => x.EmailId == OldEmailAddress).SingleOrDefault();
        u.EmailID = data.NewEmailAddress;
        db.SaveChanges();

    }
    else
        string error = "Email ID's don't match";
    return View();
}

要在 GET 方法（即加载视图的方法）中在视图中显示电子邮件，请输入以下内容，

public ActionResult Manage()
{
    // at this point you must have the username for your currently logged in user
    var u = db.UserProfiles.Where(x => x.UserName == UserName).SingleOrDefault();
    return View(u);
}

默认身份帐户控制器使用管理操作来更新或创建密码，对吗？如果您想保留这一点，我建议您为类似 ManageEmail 的内容创建另一个 GET 操作，您可以在其中返回您刚刚通过链接或单击原始管理页面下的按钮创建的视图。然后创建一个 POST 操作 ManageEmail 以与新电子邮件同步更改电子邮件/更新。

在 Manage.cshtml 中，您可以使用 Html.Action 在其中调用不同的 get 方法。

@Html.Partial("_ChangePassword") // change password partial here
@Html.Action("ManageEmail") // this will call the partial view page with your custom model

在您的 AccountController.cs 中添加以下 2 个方法：

//GET ManageEmail
public ActionResult ManageEmail()
{
   var model = new ModifyEmailModel()
    {
     OldEmailAddress = UserManager.GetEmail(User.Identity.GetUserId()) // this will load the current email for your view
    };
   return View("_ManageEmail",model); // _ManageEmail is your partial view name

}

//POST ManageEmail
[HttpPost()]
[ValidateAntiForgeryToken()]
public async Task<ActionResult> ManageEmail(ModifyEmailModel data)
{
  //some validation here like if email is valid or not existing in the database to avoid duplicate
  var user = UserManager.FindById(User.Identity.GetUserId());
  await UserManager.UpdateAsync(user);
  return RedirectToAction("Manage");
}

然后只需编辑部分视图以针对 ManageEmail POST 操作。
