WebApi 的CRUD 的方法的應用

一.最近一直在忙於開發公司的新的項目和搭建公司的框架，也很久沒有寫博客了。對於RaidDevelopmentFramework 我有着本身的看法在應用到實際的框架中確實挺好用的，可是仍是存在一部分的問題。這個須要後期進行不斷的完善以及修改。最近一段時間對於這個WebApi 我又進行從新的研究和學習。

ASP.NET Web API是用於構建能夠從任何客戶機訪問（包括瀏覽器和移動設備）的HTTP服務的框架。 它是一種基於.NET Framework構建RESTFUL應用程序的理想平臺。

二.那麼WebApi 如何在傳統的應用程序中進行使用和結合到.NET FrameWork 來進行使用。

三.ASP.NET Web API特性

1. Web API 是一個構建基於restful服務的理想平臺。

2. Web API 是基於Asp.Net,支持ASP.Net 請求/響應管道

3. Web API 有良好的路由機制。

4. Web API 支持不一樣格式的響應數據，內置支持JSON、XML BSON格式。

5. Web API 能夠部署很是方便。

6. Web API框架包括新的HttpClient，他能夠與Web API服務器通訊。HttpClient能夠在ASP.Net MVC服務器端,Windows Form應用程序,控制檯應用程序或其餘應用程序中使用。

四. 關於

 ASP.NET Web API版本

 

web api版本	支持的.net framework版本	對應的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
開源，支持.net framework	支持.net framework
只支持HTT通訊協議	支持HTTP，TCP，UDP以及自定義通訊協議等
良好的路由機制來匹配url與對應接口	基於Attribute來匹配
使用相似於Asp.net MVC的路由規則和Controller模型	使用Service，契約等
不支持可靠的消息傳遞和事務。	支持可靠的消息傳遞和事務。
可使用HttpConfiguration 來配置Web Api，不必定須要web.config配置	使用web.config和Attribute來配置一個服務
適合構建RESTful服務。	支持構建RESTful服務但有侷限性

五. 下面經過進行對於CRUD 的方法使用來進行說明。
