Chapter 3: Develop the user experience

Plan for search engine optimization and accessibility

• 使用analytical tools分析HTML，如SEO toolkit from MS,  Webmaster Tools from Google, W3C Markup Validation Service
• 使用Browser插件观察结构，如IE的F12可打开developer Toolbar。
• WAI-ARIA for accessibility

Plan and implement globalization and localization

• planning a localization strategy

1. 从HTTP头的Accept-Language取得browser的preferred language，但要设置<system.web>的<globalization culture="auto" uiculture="auto" enableclientbasedculture="true" />

• 使用resource到UI

1. 使用resx file
2. 在client端使用globalize.js

• client端主动设置culture
• 使用satellite assemblies，使用al.exe生成satellite dlls.

Design and implement MVC controllers and actions

• attributes和filters

1. RequireHttpsAttribute
2. ValidateAntiForgeryTokenAttribute
3. ValidateInputAttribute
4. AuthorizeAttribute
5. ChildActionOnlyAction
6. ActionFilterAttribute

• OnActionExecuting
• OnActionExecuted
• OnResultExecuting
• OnResultExecuted
• 使用attributes

1. on the action iteslf
2. on controller level
3. through global filters，如filters.Add(new RequireHttpsAttribute());

• 实现action的行为
• 实现action的result

1. ContentResult
2. EmptyResult
3. FileResult
4. JavaScriptResult
5. JsonResult
6. PartialViewResult
7. RedirectResult
8. RedirectToRouteResult
9. ViewResult

• 实现model binding

1. DefaultModelBinder
2. LinqBinaryModelBinder
3. ModelBinderAttribute
4. ModelBinderDictionary

weakly-typed style，如@Html.TextBox("login.UserName")

使用Bind attribute，

如public ActionResult Login([Bind(Prefix="login")]LoginUser user)

public ActionResult Save([Bind(Exclude="Salary")]Employee emp)

使用value provider取model

• • FormsValueProvider
  • QueryStringProvider
  • HttpFileCollectionValueProvider
  • RouteDataValueProvider

Design and implement routes

• 使用MapRoute定义一个route
• 使用route的限制，如 new {id=@"\d+"}
• ignore一个route
• Adding custom route parameters
• 使用area

Control application behavior by using MVC extensibility points

• 使用filter和controller factory

1. Authorization
2. Action
3. Result
4. Exception

• 通过action result控制，override ExecuteResult() of System.Web.Mvc.ActionResult
• 通过view engine
• 通过model binder
• 通过route handler
