SportsStore是《精通ASP.NET MVC3框架(第三版)》中演示的MVC项目，在该项目中涵盖了MVC的众多方面，包括：使用DI容器、URL优化、导航、分页、购物车、订单、产品管理、图像上传......是不错的MVC实践项目，但该项目不是放在多层框架下开发的，离真实项目还有一段距离。本系列将尝试在多层框架下实现SportsStore项目，并用自己的方式实现一些功能。

本篇为系列第七篇，包括：

■ 9、实现订单提交

9、实现订单提交

首先在购物车显示页面Cart/Index.cshtml中，添加结账按钮：

@model MySportsStore.WebUI.Models.CartIndexViewModel@{    ViewBag.Title = "Index";    Layout = "~/Views/Shared/_Layout.cshtml";}<table width="50%" align="left">    <thead>        <tr>            <th align="left">产品名称</th>            <th align="center">数量</th>                      <th align="right">单价</th>            <th align="right">小计</th>            <th></th>        </tr>    </thead>    <tbody>        @foreach (var line in Model.Cart.Lines)        {            <tr>                <td align="left">@line.Product.Name</td>                <td align="center">@line.Quantity</td>                <td align="right">@line.Product.Price.ToString("c")</td>                <td align="right">@((line.Quantity * line.Product.Price).ToString("c"))</td>                <td>                    @using (Html.BeginForm("RemoveFromCart", "Cart"))                    {                        @Html.Hidden("Id", line.Product.Id)                        @Html.HiddenFor(x => x.ReturnUrl)                        <input class="actionButtons" type="submit" value=http://www.mamicode.com/"移除"/>                    }                </td>            </tr>        }    </tbody>    <tfoot>        <tr>            <td colspan="3" align="right">总计：</td>            <td align="right">@Model.Cart.ComputeTotalValue().ToString("c")</td>        </tr>    </tfoot></table><p align="left" class="actionButtons" style="width: 100%;clear: both">    <a href=http://www.mamicode.com/"@Model.ReturnUrl">继续购物</a>    @Html.ActionLink("结账","CheckOut")</p>

点击结账，跳转到一个视图页面，填写必要的联系方式等信息，其对应的模型为：

using System.ComponentModel.DataAnnotations;namespace MySportsStore.Model{    public class ShippingDetail    {        [Required(ErrorMessage = "必填")]        [Display(Name = "姓名")]        public string Name { get; set; }        [Required(ErrorMessage = "必填")]        [Display(Name = "地址")]        public string Line { get; set; }    }}

订单提交页Cart/CheckOUt.cshtml：

@model MySportsStore.Model.ShippingDetail@{    ViewBag.Title = "CheckOut";    Layout = "~/Views/Shared/_Layout.cshtml";}<h2>填写地址等信息</h2>@using (Html.BeginForm()){    @Html.LabelFor(m => m.Name)    @Html.EditorFor(m => m.Name)    @Html.ValidationMessageFor(m => m.Name)    <br/><br/>    @Html.LabelFor(m => m.Line)    @Html.EditorFor(m => m.Line)    @Html.ValidationMessageFor(m => m.Line)    <p align="center">        <input class="actionButtons" type="submit" value=http://www.mamicode.com/"提交订单"/>    </p>}

在为Cart控制器添加处理订单的方法之前，我们首先定义一个处理订单的接口：

using MySportsStore.Model;using MySportsStore.WebUI.Models;namespace MySportsStore.WebUI.Abstract{    public interface IOrderProcessor    {        void ProcessOrder(Cart cart, ShippingDetail shippingDetail);    }}

假设，我们希望在接到订单时发邮件给管理员，创建一个实现IOrderProcessor的类：

using System.Net;using System.Net.Mail;using System.Text;using MySportsStore.WebUI.Abstract;namespace MySportsStore.WebUI.Concrete{    public class EmailOrderProcessor : IOrderProcessor    {        public void ProcessOrder(Models.Cart cart, Model.ShippingDetail shippingDetail)        {            MailMessage mailMsg = new MailMessage();            mailMsg.From = new MailAddress("qdjjx9441@sina.com");            mailMsg.To.Add(new MailAddress("764190362@qq.com"));            mailMsg.Subject = "新订单";                      //邮件内容主体            StringBuilder body = new StringBuilder();            body.AppendLine("接收到一个新订单：");            body.AppendLine("<br />");            body.AppendLine("订购商品包括：");            body.AppendLine("<br />");            foreach (var line in cart.Lines)            {                var subTotal = line.Product.Price * line.Quantity;                body.AppendFormat("{0}*{1}(小计：{2:c})", line.Quantity, line.Product.Name, subTotal);                body.AppendLine("<br />");            }            body.AppendFormat("总计:{0:c}", cart.ComputeTotalValue());            body.AppendLine("<br />");            body.AppendLine("收货人信息：");            body.AppendLine(shippingDetail.Name);            body.AppendLine(shippingDetail.Line);            body.AppendLine("<br />");            mailMsg.Body = body.ToString();            mailMsg.IsBodyHtml = true;            SmtpClient smtpClient = new SmtpClient("smtp.sina.com");            smtpClient.Credentials = new NetworkCredential("some username", "some password");            smtpClient.Send(mailMsg);        }    }}

把接口IOrderProcessor和实现类EmailOrderProcessor交给Ninject来实现，以便依赖注入：

private void AddBindings()        {            ninjectKernel.Bind<IProductService>().To<ProductService>();            ninjectKernel.Bind<IOrderProcessor>().To<EmailOrderProcessor>();        }

现在可以在Cart控制器中添加处理订单的逻辑：

using System.Linq;using System.Web.Mvc;using MySportsStore.IBLL;using MySportsStore.Model;using MySportsStore.WebUI.Abstract;using MySportsStore.WebUI.Models;using Ninject;namespace MySportsStore.WebUI.Controllers{    public class CartController : BaseController    {        [Inject]        public IProductService ProductService { get; set; }        [Inject]        public IOrderProcessor OrderProcessor { get; set; }        public CartController()        {            this.AddDisposableObject(ProductService);            this.AddDisposableObject(OrderProcessor);        }        public ViewResult CheckOut()        {            return View(new ShippingDetail());        }        [HttpPost]        public ViewResult CheckOut(Cart cart, ShippingDetail shippingDetail)        {            if (cart.Lines.Count() == 0)            {                ModelState.AddModelError("","购物车为空");            }            if (ModelState.IsValid)            {                OrderProcessor.ProcessOrder(cart, shippingDetail);                cart.Clear();                return View("Completed");            }            else            {                return View(shippingDetail);            }        }        ......    }}

订单提交成功后，显示Cart/Completed.cshtml视图：

@{    ViewBag.Title = "Completed";    Layout = "~/Views/Shared/_Layout.cshtml";}<h2>谢谢惠顾~~</h2>

运行，点击提交显示：

管理员收到邮件：

order

至此，订单处理结束。
