2018教程之mvc+ef之二：更改Mail登录为UserName登记并让注册密码简单化

这章先简单解决两个问题：

1.注册和登录使用Email,个人感觉 不喜欢，好复杂，难得输。

2.在注册时，默认使用大小写，加符号太过于复杂，我想简化。当然可以不改

一、让注册密码简单化

 App_Start/IdentityConfig.cs文件中 ApplicationUserManager.Create 静态方法中：

// 配置密码的验证逻辑
manager.PasswordValidator = new PasswordValidator
{
///长度为6
RequiredLength = 6,
///必须有非字母数字字符
RequireNonLetterOrDigit = false,
///必须有数字
RequireDigit = false,
///必须有小写字毒
RequireLowercase = false,
///必须有大写字毒
RequireUppercase = false,
};

　我将他全部改为false

　重新生成解决方案后，运行测试。测试成功。

二、更改UserName方式进行注册

1.打开AccountViewModels.cs，找到RegisterViewModel中的注册模型的更改。

public class RegisterViewModel
   {
         
       #region 扩展
 
          [Display(Name = "用户名")]
       public string UserName { get; set; }
 
 
       [Display(Name = "电话(手机/固话)")]
       [Phone]
       public string PhoneNumber { get; set; }
       #endregion
         
 
 
               [Required]
       [EmailAddress]
       [Display(Name = "电子邮件")]
       public string Email { get; set; }
 
       [Required]
       [StringLength(100, ErrorMessage = "{0} 必须至少包含 {2} 个字符。", MinimumLength = 6)]
       [DataType(DataType.Password)]
       [Display(Name = "密码")]
       public string Password { get; set; }
 
       [DataType(DataType.Password)]
       [Display(Name = "确认密码")]
       [Compare("Password", ErrorMessage = "密码和确认密码不匹配。")]
       public string ConfirmPassword { get; set; }
   }

　2. 然后我们修改Register.cshtml  添加如下代码：下面的代码我们放在邮箱的上面。

 

  @Html.AntiForgeryToken()
    <h4>创建新帐户。</h4>
    <hr />
    @Html.ValidationSummary("", new { @class = "text-danger" })
	<div class="form-group">
		@Html.LabelFor(m => m.UserName, new { @class = "col-md-2 control-label" })
		<div class="col-md-10">
			@Html.TextBoxFor(m => m.UserName, new { @class = "form-control" })
		</div>
	</div>
	<div class="form-group">
		@Html.LabelFor(m => m.PhoneNumber, new { @class = "col-md-2 control-label" })
		<div class="col-md-10">
			@Html.PasswordFor(m => m.PhoneNumber, new { @class = "form-control" })
		</div>
	</div>
	
    <div class="form-group">
        @Html.LabelFor(m => m.Email, new { @class = "col-md-2 control-label" })
        <div class="col-md-10">
            @Html.TextBoxFor(m => m.Email, new { @class = "form-control" })
        </div>
    </div>
    <div class="form-group">
        @Html.LabelFor(m => m.Password, new { @class = "col-md-2 control-label" })
        <div class="col-md-10">
            @Html.PasswordFor(m => m.Password, new { @class = "form-control" })
        </div>
    </div>

　　

3.修改 Register方法。AccountController.cs中找到Register方法

因为我加入 一个创建时间的datetime非空属性，要取当时的时候，同时我搞了个头像，注册时默认的为某个图像。

[HttpPost]
        [AllowAnonymous]
        [ValidateAntiForgeryToken]
        public async Task<ActionResult> Register(RegisterViewModel model)
        {
            if (ModelState.IsValid)
            {
				var _creatTime = DateTime.Now;
				var _headerPic = "/Content/noheaderpic.png";
				var user = new ApplicationUser { UserName = model.UserName, Email = model.Email, PhoneNumber = model.PhoneNumber, CreateTime = _creatTime, HeaderPic = _headerPic };
				var result = await UserManager.CreateAsync(user, model.Password);
                if (result.Succeeded)
                {
                    await SignInManager.SignInAsync(user, isPersistent:false, rememberBrowser:false);
                    
                    // For more information on how to enable account confirmation and password reset please visit https://go.microsoft.com/fwlink/?LinkID=320771
                    // 发送包含此链接的电子邮件
                    // string code = await UserManager.GenerateEmailConfirmationTokenAsync(user.Id);
                    // var callbackUrl = Url.Action("ConfirmEmail", "Account", new { userId = user.Id, code = code }, protocol: Request.Url.Scheme);
                    // await UserManager.SendEmailAsync(user.Id, "确认你的帐户", "请通过单击 <a href=\"" + callbackUrl + "\">這裏</a>来确认你的帐户");

                    return RedirectToAction("Index", "Home");
                }
                AddErrors(result);
            }

　　

三、使用UserName进行登录

Models下AccountViewModels中，改更   public class LoginViewModel 模型，将EMAIL改为user

 public class LoginViewModel
    {
        [Required]
        [Display(Name = "用户名")]
        public string UserName { get; set; }

        [Required]
        [DataType(DataType.Password)]
        [Display(Name = "密码")]
        public string Password { get; set; }

        [Display(Name = "记住我?")]
        public bool RememberMe { get; set; }
    }

然后更改控制器的登录。AccountController

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

然后修改登录视图，将email改为username控件名

打开进行测试，注册和登录成功。
