WebApi 的CRUD 的方法的应用

一.最近一直在忙于开发公司的新的项目和搭建公司的框架，也好久没有写博客了。对于RaidDevelopmentFramework 我有着自己的见解在应用到实际的框架中确实挺好用的，但是还是存在一部分的问题。这个需要后期进行不断的完善以及修改。最近一段时间对于这个WebApi 我又进行重新的研究和学习。

ASP.NET Web API是用于构建可以从任何客户机访问（包括浏览器和移动设备）的HTTP服务的框架。它是一种基于.NET Framework构建RESTFUL应用程序的理想平台。

二.那么WebApi 如何在传统的应用程序中进行使用和结合到.NET FrameWork 来进行使用。

三.ASP.NET Web API特性

Web API 是一个构建基于restful服务的理想平台。
Web API 是基于Asp.Net,支持ASP.Net 请求/响应管道
Web API 有良好的路由机制。
Web API 支持不同格式的响应数据，内置支持JSON、XML BSON格式。
Web API 可以部署非常方便。
Web API框架包括新的HttpClient，他可以与Web API服务器通信。HttpClient可以在ASP.Net MVC服务器端,Windows Form应用程序,控制台应用程序或其他应用程序中使用。

四. 关于

ASP.NET Web API版本

web api版本	支持的.net framework版本	对应的MVC版本	支持的VS版本
Web API 1.0	.NET Framework 4.0	ASP.NET MVC 4	VS 2010
Web API 2.0	.NET Framework 4.5	ASP.NET MVC 5	VS 2012，VS 2013

ASP.NET Web API VS WCF

web api	wcf
开源，支持.net framework	支持.net framework
只支持HTT通信协议	支持HTTP，TCP，UDP以及自定义通信协议等
良好的路由机制来匹配url与对应接口	基于Attribute来匹配
使用类似于Asp.net MVC的路由规则和Controller模型	使用Service，契约等
不支持可靠的消息传递和事务。	支持可靠的消息传递和事务。
可以使用HttpConfiguration 来配置Web Api，不一定需要web.config配置	使用web.config和Attribute来配置一个服务
适合构建RESTful服务。	支持构建RESTful服务但有局限性

五. 下面通过进行对于CRUD 的方法使用来进行说明。
