using System.Collections.Generic;using BrnShop.Core;namespace BrnShop.Web.Framework
{/// summary/// 商城前台工作上下文类/// /summarypublic class WebWorkContext{public ShopConfigInfo ShopConfig BSPConfig.ShopConfig;//商城配置信息public bool IsHttpAjax;//当前请求是否为ajax请求public string IP;//用户ippublic RegionInfo Region;//区域信息public string Url;//当前urlpublic string UrlReferrer;//上一次访问的urlpublic string Sid;//用户sidpublic int Uid -1;//用户idpublic string UserName;//用户名public string UserEmail;//用户邮箱public string UserMobile;//用户手机号public string NickName;//用户昵称public string Avatar;//用户头像public string Password;//用户密码public string PayCreditName;//支付积分名称public int PayCreditCount 0;//支付积分数量public string RankCreditName;//等级积分名称public int RankCreditCount 0;//等级积分数量public PartUserInfo PartUserInfo;//用户信息public int UserRid -1;//用户等级idpublic UserRankInfo UserRank;//用户等级信息public string UserRTitle;//用户等级标题public int AdminGid -1;//用户管理员组idpublic AdminGroupInfo AdminGroup;//用户管理员组信息public string AdminGTitle;//管理员组标题public string Controller;//控制器public string Action;//动作方法public string PageKey;//页面标示符public string ThemeName;//当前主题名称public string ImageDir;//图片目录public string CSSDir;//css目录public string ScriptDir;//脚本目录public int OnlineUserCount 0;//在线总人数public int OnlineMemberCount 0;//在线会员数public int OnlineGuestCount 0;//在线游客数public string SearchWord;//搜索词public int SCProductCount 0;//购物车中商品数量public ListCategoryInfo CategoryList;//分类列表public ListNavInfo NavList;//导航列表public FriendLinkInfo[] FriendLinkList;//友情链接列表public ListHelpInfo HelpList;//帮助列表public DateTime StartExecuteTime;//页面开始执行时间public double ExecuteTime;//页面执行时间public int ExecuteCount 0;//执行的sql语句数目public string ExecuteDetail;//执行的sql语句细节public string ShopVersion BSPVersion.SHOP_VERSION;//商城版本public string ShopCopyright BSPVersion.SHOP_COPYRIGHT;//商城版权

} View Code 有了上下文类后我们需要找一个可以保证上下文流动的地方。在翻看了asp.net mvc的源码后我们找到一个好地方这个地方就在控制器的基类Controller中。在Controller中微软定义了六个方法具体如下 protected override void Initialize(RequestContext requestContext);说明初始化调用构造函数后可能不可用的数据。protected virtual void OnAuthorization(AuthorizationContext filterContext);说明在进行授权时调用。protected virtual void OnActionExecuted(ActionExecutedContext filterContext);说明在调用操作方法后调用。protected virtual void OnActionExecuting(ActionExecutingContext filterContext);说明在调用操作方法前调用。protected virtual void OnResultExecuted(ResultExecutedContext filterContext);说明在执行由操作方法返回的操作结果后调用。protected virtual void OnResultExecuting(ResultExecutingContext filterContext);说明在执行由操作方法返回的操作结果前调用。 这些都是虚方法所以我们可以定义一个继承自Controller的新控制器然后重写这些方法。由于这些方法是在同一个类中所以它们可以共享同一个字段(这个字段就是上下文)而且其他的控制器都是继承自这个新控制器类所以在动作方法中也是可以访问这个共享字段(父类的字段)。新控制器类分别是BrnShop.Web.Framework项目中BaseWebController类和BaseAdminController类其中BaseWebController为前台控制器类BaseAdminController为后台控制器类具体实现如下 using System;

} View Code 定义好新的视图类后我们需要通知编译器使用这个新类通知方式在视图文件的web.config中具体见下图 通过将pageBaseType的值设置为我们的新类名我们就可以在视图文件中直接使用上下文了。例WorkContext.ShopConfig.SEOKeyword 说完了数据的复用和传递我们再来说说大mvc框架和小mvc框架的问题。首先何为大mvc框架何为小mvc框架 大mvc框架指的是尽量完整的一套asp.net mvc框架包含路由控制器模型绑定模型校验筛选器等等。小mvc框架指的是只包含项目所必须使用的mvc部分对于使用不到的部分尽量不用或移除。 大家可能觉得这有什么难的但是对于一个开源项目来说这确实是一个很重要的问题因为开源项目的产品面向的是全国甚至是全世界的开发者大家的技术参差不齐有的高有个低。为了保证尽可能多的覆盖开发者只有原汁原味的mvc才对开发者更亲切和熟悉所以应该使用大mvc框架。可是一款优秀的产品不只是面向初级开发者还需要面对高级开发者对于高级开发者来说他们希望获得项目最大的可控权所以框架应该尽量只使用最核心的mvc部分这样留给开发者的空间才能更大这样这样看来又应该使用小mvc框架。下面我从两个方面来说明我们是如何解决这个问题的。 首先是mvc筛选器看过我们源码的园友已经发现我们项目中没有定义任何一个筛选器类。那我们的筛选器在哪儿答案就在上面的上下文流动中在上面重写的筛选器方法中我们实现所有筛选。如果你想针对某个控制器A单独筛选你可以在A中再一次重写筛选器方法添加自己的代码。如果你想只针对某一方法进行筛选你只需要单独在方法中筛选就可以了。这样通过使用内置在controller中的筛选方法我们实现了和第三方筛选器的隔离也减少了反射获取筛选器的次数。 其次是模型绑定和校验我们首先通过手动获取request集合的方式去除所有模型绑定以登陆代码为例 /// summary/// 登录/// /summarypublic ActionResult Login()//注意此方面没有任何参数{string returnUrl WebHelper.GetQueryString(returnUrl);if (returnUrl.Length 0)returnUrl /;if (WorkContext.ShopConfig.LoginType )return PromptView(returnUrl, 商城目前已经关闭登陆功能!);if (WorkContext.Uid 0)return PromptView(returnUrl, 您已经登录无须重复登录!);if (WorkContext.ShopConfig.LoginFailTimes ! 0 LoginFailLogs.GetLoginFailTimesByIp(WorkContext.IP) WorkContext.ShopConfig.LoginFailTimes)return PromptView(returnUrl, 您已经输入错误 WorkContext.ShopConfig.LoginFailTimes 次密码请15分钟后再登陆!);//get请求if (WebHelper.IsGet()){ViewData.Add(oAuthPluginList, Plugins.GetOAuthPluginList());return View(new LoginModel());}//post请求LoginModel model new LoginModel();//模型绑定 手动绑定model.AccountName WebHelper.GetFormString(WorkContext.ShopConfig.ShadowName).Trim();model.Password WebHelper.GetFormString(password);model.IsRemember WebHelper.GetFormInt(isRemember);model.VerifyCode WebHelper.GetFormString(verifyCode);//模型验证PartUserInfo partUserInfo VerifyLogin(model);if (!ModelState.IsValid)//验证失败时{ViewData.Add(oAuthPluginList, Plugins.GetOAuthPluginList());return View(model);}else//验证成功时{//当用户等级是禁止访问等级时if (partUserInfo.UserRid 1)return PromptView(您的账号当前被锁定,不能访问);//删除登陆失败日志LoginFailLogs.DeleteLoginFailLogByIP(WorkContext.IP);//更新用户最后访问int regionId WorkContext.Region ! null ? WorkContext.Region.RegionId : -1;Users.UpdateUserLastVisit(partUserInfo.Uid, WorkContext.IP, regionId, DateTime.Now);//更新购物车中用户idOrders.UpdateShopCartUidBySid(partUserInfo.Uid, WorkContext.Sid);//将用户信息写入cookie中ShopUtils.SetUserCookie(partUserInfo, (WorkContext.ShopConfig.IsRemember 1 model.IsRemember 1) ? 30 : -1);return Redirect(returnUrl);}} 其次是模型校验校验又分为两部分。第一部分是验证对此我们也是采用手动校验的方式同样以登陆为例 /// summary/// 登录验证/// /summaryprivate PartUserInfo VerifyLogin(LoginModel model){PartUserInfo partUserInfo null;//验证账户名if (string.IsNullOrWhiteSpace(model.AccountName)){ModelState.AddModelError(WorkContext.ShopConfig.ShadowName, 账户名不能为空);}else if (model.AccountName.Length 4 || model.AccountName.Length 50){ModelState.AddModelError(WorkContext.ShopConfig.ShadowName, 账户名必须大于3且不大于50个字符);}else if ((!SecureHelper.IsSafeSqlString(model.AccountName))){ModelState.AddModelError(WorkContext.ShopConfig.ShadowName, 账户名不存在);}//验证密码if (string.IsNullOrWhiteSpace(model.Password)){ModelState.AddModelError(password, 密码不能为空);}else if (model.Password.Length 4 || model.Password.Length 32){ModelState.AddModelError(password, 密码必须大于3且不大于32个字符);}//验证验证码if (CommonHelper.IsInArray(WorkContext.PageKey, WorkContext.ShopConfig.VerifyPages)){if (string.IsNullOrWhiteSpace(model.VerifyCode)){ModelState.AddModelError(verifyCode, 验证码不能为空);}else if (model.VerifyCode.ToLower() ! Sessions.GetValueString(WorkContext.Sid, verifyCode)){ModelState.AddModelError(verifyCode, 验证码不正确);}}//当以上验证全部通过时if (ModelState.IsValid){if (BSPConfig.ShopConfig.LoginType.Contains(2) ValidateHelper.IsEmail(model.AccountName))//邮箱登陆{partUserInfo Users.GetPartUserByEmail(model.AccountName);if (partUserInfo null)ModelState.AddModelError(WorkContext.ShopConfig.ShadowName, 邮箱不存在);}else if (BSPConfig.ShopConfig.LoginType.Contains(3) ValidateHelper.IsMobile(model.AccountName))//手机登陆{partUserInfo Users.GetPartUserByMobile(model.AccountName);if (partUserInfo null)ModelState.AddModelError(WorkContext.ShopConfig.ShadowName, 手机不存在);}else if (BSPConfig.ShopConfig.LoginType.Contains(1))//用户名登陆{partUserInfo Users.GetPartUserByName(model.AccountName);if (partUserInfo null)ModelState.AddModelError(WorkContext.ShopConfig.ShadowName, 用户名不存在);}//判断密码是否正确if (partUserInfo ! null Users.CreateUserPassword(model.Password, partUserInfo.Salt) ! partUserInfo.Password){LoginFailLogs.AddLoginFailTimes(WorkContext.IP, DateTime.Now);//增加登陆失败次数ModelState.AddModelError(password, 密码不正确);}}return partUserInfo;} 通过上面代码大家可以看出所有的验证都是手动进行的。 校验的第二部分是验证信息显示在mvc中大家经常使用Html.ValidationMessageFor之类的方法来显示验证信息所以为了保证上述方法还能够正常使用我们需要将所有验证信息都添加到ModelState中因为Html.ValidationMessageFor之类的方法实现本质就是通过获取ModelState指定键值的内容来判断是否显示和显示什么内容。到此我们已经有了校验数据剩下的就是在视图中显示了。关于显示我们仍然可以使用Html.ValidationMessageFor之类的方法如果你想获得更大的灵活性你可以使用视图页面的“GetVerifyErrorList”方法此方法在我们新定义的视图基类中它的功能就是将校验信息构建成一个json对象。代码如下 /// summary/// 获得验证错误列表/// /summary/// returns/returnspublic MvcHtmlString GetVerifyErrorList(){ModelStateDictionary modelState ((Controller)(this.ViewContext.Controller)).ModelState;if (modelState null || modelState.Count 0)return new MvcHtmlString(null);StringBuilder errorList new StringBuilder([);foreach (KeyValuePairstring, ModelState item in modelState){errorList.AppendFormat({0}key:{1},msg:{2}{3},, {, item.Key, item.Value.Errors[0].ErrorMessage, });}errorList.Remove(errorList.Length - 1, 1);errorList.Append(]);return new MvcHtmlString(errorList.ToString());} 下面给出一个使用例子代码是登陆视图的代码 //脚本代码 script typetext/javascriptvar verifyErrorList GetVerifyErrorList();$(function(){if (verifyErrorList ! null) {for(var i 0; i verifyErrorList.length; i){$(#verifyErrorList[i].keyError).html(verifyErrorList[i].msg)}}})/script//html代码trtd密码/tdtdinput typepassword namepassword idpassword valueModel.Password//tdtdspan stylecolor: Red; idpasswordError/span/td/tr 通过以上实现我们既保证框架能够兼容mvc各个功能又为高级开发者提供了足够的扩展空间。PS团队中有位同事曾经将asp.net mvc源码中有关模型绑定和模型校验的代码全部删除并完美运行实例性能和开销都少了不少有兴趣的朋友可以去试试 如果想下载商城源码可以点此下载。有对网上商城程序设计感兴趣的朋友欢迎加入QQ群235274151大家可以交流下 posted on 2014-06-26 17:51 NET未来之路 阅读(...) 评论(...) 编辑 收藏 转载于:https://www.cnblogs.com/lonelyxmas/p/3810565.html
