1、首先新建一个修改密码的的视图模型（viewmodel）
using System.Collections.Generic; using System.ComponentModel; using System.ComponentModel.DataAnnotations; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Web.Mvc; namespace BM.Model { public class PasswordModel { /// <summary> /// 原密码 /// </summary> [DisplayName("初始密码")] // 显示名字 [Required(ErrorMessage = "初始密码密码不能为空")] // 不能为空特性 [Remote("CheckPasswordIsOk", "User", ErrorMessage = "初始密码不正确", HttpMethod = "GET")] // 远程验证 User控制器下的 CheckPasswordIsOk 下去验证 //[DataType(DataType.Password)] public string Password { get; set; } /// <summary> /// 新密码 /// </summary> [DisplayName("新 密 码")] [Required(ErrorMessage = "新密码不能为空")] public string NewPassword { get; set; } /// <summary> /// 确认密码 /// </summary> [DisplayName("确认密码")] [System.ComponentModel.DataAnnotations.Compare("NewPassword", ErrorMessage = "新密码不匹配")] // 比较字段 public string ConfirmPassword { get; set; } } }
2、 新建一个强类型视图
@{ Layout = null; } @model BM.Model.PasswordModel <!DOCTYPE html> <html> <head> <title>修改密码</title> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <link href="~/Content/layer/skin/layer.css" rel="stylesheet" /> <script src="~/Scripts/jquery-1.10.2.js"></script> <script src="~/Scripts/jquery.validate.js"></script> <script src="~/Scripts/jquery.unobtrusive-ajax.min.js"></script> // 这里需要注意的是： 使用Ajax.BeginForm提交表单是一定需要它，不然提交成功需要执行的js代码无法执行 <script src="~/Scripts/jquery.validate.unobtrusive.js"></script> <script src="~/Content/layer/layer.js"></script> <style> * { padding: 0; margin: 0; } .title { display: inline-block; auto; height: 34px; font-size: 22px; font-family: "宋体"; font-weight: 500; /*color: #fff; background-color:#0094ff;*/ } .row { margin: 8px; } .row input[type=text], .row input[type=password] { 300px; height: 30px; border: 1px solid #ddd; } .row input[type=submit] { text-align: center; line-height: inherit; 150px; height: 40px; font-size: 26px; margin-left: 80px; margin-top: 3px; color: #fff; background-color: #0094ff; } .field-validation-error { color: red; display: block; } </style> </head> <body> <div class="content"> <h2 style="text-align:center">修改密码</h2> <div class="form"> @using (@Ajax.BeginForm("ChangePassword", "User", new AjaxOptions() { InsertionMode = InsertionMode.Replace, HttpMethod = "POST", OnComplete = "complete" }, new { id = "form" })) { @Html.AntiForgeryToken(); // 防止CSFR 攻击，配合控制器上的 ValidateAntiForgeryToken 一起使用 <div class="row"> <span class="title">@Html.DisplayNameFor(c => c.Password):</span> @Html.PasswordFor(c => c.Password) @Html.ValidationMessageFor(c => c.Password) </div> <div class="row"> <span class="title">@Html.DisplayNameFor(c => c.NewPassword):</span> @Html.PasswordFor(c => c.NewPassword) @Html.ValidationMessageFor(c => c.NewPassword) </div> <div class="row"> <span class="title">@Html.DisplayNameFor(c => c.ConfirmPassword):</span> @Html.PasswordFor(c => c.ConfirmPassword) @Html.ValidationMessageFor(c => c.ConfirmPassword) </div> <div class="row"> <input id="btnSubmit" type="submit" value="确 认" /> </div> } </div> </div> </body> </html> <script> function complete(data) { var json = JSON.parse(data.responseText); layer.msg('恭喜你，密码修改成功,请重新登录！！', { time: 3000, icon: 1 }); setTimeout(function () { window.top.location.href = json.BackUrl; }, 2000); } </script>
3. 以下是控制器中方法
/// <summary> /// 修改密码 /// </summary> /// <returns></returns> [HttpGet] public ActionResult ChangePassword() { if (Session[CurrentUser] == null) { return Redirect("/user/login"); } return View(); } [HttpPost, ValidateAntiForgeryToken] public ActionResult ChangePassword(PasswordModel model) { using (BusinessManageEntities db = new BusinessManageEntities()) { int userId = (int)Session[CurrentUser]; var bm = db.BusinessManager.Where(c => c.UserId == userId).FirstOrDefault(); bm.BizPassword = Utils.Md5(model.NewPassword); db.SaveChanges(); } //return Content("<script>base.AlertTip('修改密码成功');window.location.href='/user/login';</script>"); return Json(new { Message = "修改密码成功", BackUrl = "/user/login" }, JsonRequestBehavior.AllowGet); } /// <summary> /// 检查用户密码是否正确 /// </summary> /// <param name="Password">旧密码</param> /// <returns></returns> [HttpGet] public ActionResult CheckPasswordIsOk(string password) { if (Session[CurrentUser] == null) { return Redirect("/user/login"); } int userId = (int)Session[CurrentUser]; using (BusinessManageEntities db = new BusinessManageEntities()) { var bm = db.BusinessManager.Where(c => c.UserId == userId).FirstOrDefault(); if (bm.BizPassword.Equals(Utils.Md5(password))) { return Json(true, JsonRequestBehavior.AllowGet); } } return Json(false, JsonRequestBehavior.AllowGet); }
