一用户
1.1用户注册
1.2用户登陆
首先在Models里添加用户登陆模型类UserLogin，该类只要用用户名，密码和验证码三个字段。
/// <summary> /// 用户登陆模型 /// </summary> public class UserLogin { /// <summary> /// 用户名 /// </summary> [Display(Name = "用户名", Description = "4-20个字符。")] [Required(ErrorMessage = "×")] [StringLength(20, MinimumLength = 4, ErrorMessage = "×")] public string UserName { get; set; } /// <summary> /// 密码 /// </summary> [Display(Name = "密码", Description = "6-20个字符。")] [Required(ErrorMessage = "×")] [StringLength(20, MinimumLength = 6, ErrorMessage = "×")] [DataType(DataType.Password)] public string Password { get; set; } /// <summary> /// 验证码 /// </summary> [Display(Name = "验证码", Description = "请输入图片中的验证码。")] [Required(ErrorMessage = "×")] [StringLength(6, MinimumLength = 6, ErrorMessage = "×")] public string VerificationCode { get; set; } }
在UserController里添加Login action； 代码看如下：
public ActionResult Login() { return View(); } [HttpPost] public ActionResult Login(UserLogin login) { return View(); }
使用Cookie保存登陆账号，密码等信息，修改public ActionResult Login(UserLogin login)。修改完成代码如下：
[HttpPost] public ActionResult Login(UserLogin login) { //验证验证码 if (Session["VerificationCode"] == null || Session["VerificationCode"].ToString() == "") { Error _e = new Error { Title = "验证码不存在", Details = "在用户注册时，服务器端的验证码为空，或向服务器提交的验证码为空", Cause = "<li>你注册时在注册页面停留的时间过久页已经超时</li><li>您绕开客户端验证向服务器提交数据</li>", Solution = "返回<a href='" + Url.Action("Register", "User") + "'>注册</a>页面，刷新后重新注册" }; return RedirectToAction("Error", "Prompt", _e); } else if (Session["VerificationCode"].ToString() != login.VerificationCode.ToUpper()) { ModelState.AddModelError("VerificationCode", "×"); return View(); } //验证账号密码 userRsy = new UserRepository(); if (userRsy.Authentication(login.UserName, Common.Text.Sha256(login.Password)) == 0) { HttpCookie _cookie = new HttpCookie("User"); _cookie.Values.Add("UserName", login.UserName); _cookie.Values.Add("Password", Common.Text.Sha256(login.Password)); Response.Cookies.Add(_cookie); return RedirectToAction("Default","User"); } else { ModelState.AddModelError("Message", "登陆失败！"); return View(); } }
在public ActionResult Login() 上右键添加强类型视图
完成后代的Login.cshtml
@model CMS.Models.UserLogin @{ ViewBag.Title = "用户登陆"; Layout = "~/Views/Shared/_Layout.cshtml"; } <div> <img src="https://www.jb51.net/~/Skins/Default/Images/banner.jpg" /> </div> @using (Html.BeginForm()) { @Html.ValidationSummary(true) <div> <dl> <dt>用户登陆</dt> <dd> <div>@Html.LabelFor(model => model.UserName)：</div> <div>@Html.EditorFor(model => model.UserName) @Html.ValidationMessageFor(model => model.UserName) @Html.DisplayDescriptionFor(model => model.UserName) </div> </dd> <dd> <div>@Html.LabelFor(model => model.Password)：</div> <div>@Html.PasswordFor(model => model.Password) @Html.ValidationMessageFor(model => model.Password) @Html.DisplayDescriptionFor(model => model.Password) </div> </dd> <dd> <div>验证码：</div> <div> @Html.TextBoxFor(model => model.VerificationCode) @Html.ValidationMessageFor(model => model.VerificationCode) <img alt="" src="https://www.jb51.net/@Url.Action("VerificationCode", "User")" /> <a>换一张</a> </div> </dd> <dd> <div></div> <div> <input type="submit" value="登陆" />@Html.ValidationMessage("Message"); </div> </dd> </dl> <div></div> </div> } <script type="text/javascript"> $("#trydifferent").click(function () { $("#verificationcode").attr("src", "/User/VerificationCode?" + new Date()); }) </script> @section Scripts { @Scripts.Render("~/bundles/jqueryval") }
浏览器中查看一下登陆页面
点下登陆测试一下。OK登陆成功
验证用户是否已经登陆，这块和权限验证一起从AuthorizeAttribute继承个自定义验证类
