1、啥是RESTFul 服务
在我们创建简单小程序前,先来学习下RESTFul 服务。RESTFul服务就是遵循了 Representational State Transfer(可以参考http://blog.csdn.net/zhruifei/article/details/50633495) 这个架构的一种架构。WCF允许我们使用SOAP 通过各种协议,协议包括,HTTP,TCP,MSMQ,Named Pipes等进行交换信息。现在我们通过一个最常用的协议HTTP协议来讲述WCF服务,REST服务通过HTTP来进行最常用的CRUD(Read(GET)/Create(POST)/Update(PUT)/Delete(DELETE))功能,在这里我们先实现一个简单的GET功能
2、创建restful 服务
下面是5步创建你的rest服务并且返回xml格式
1)打开vs-新建项目-选择WCF服务应用程序
2,新建一个类 car.cs
[DataContract] public class Car { [DataMember] public string color { get; set; } [DataMember] public double speed { get; set; } [DataMember] public double price { get; set; } } public partial class Cars { public static readonly Cars _instance = new Cars(); private Cars() { } public static Cars Instance { get { return _instance; } } public List<Car> CarList { get { return carLists; } } private List<Car> carLists = new List<Car> { new Car { color = "red", speed = 200, price = 200 }, new Car{color = "blue", speed = 200, price = 200}, new Car{color="green",speed=300,price=400} }; }
3)新建WCF 服务--如下图所示
系统将新疆两个文件,包括ICarRestService.cs 接口文件如下图所示:
下面我们将Dowork 方法改为GetCarList 方法
如下所示:
5)配置服务和行为
<?xml version="1.0"?> <configuration> <appSettings> <add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" /> </appSettings> <system.web> <compilation debug="true" targetFramework="4.5" /> <httpRuntime targetFramework="4.5"/> </system.web> <system.serviceModel> <services> <service name="MyRESTService.ProductRESTService" behaviorConfiguration="serviceBehavior"> <endpoint address="" binding="webHttpBinding" contract="MyRESTService.IProductRESTService" behaviorConfiguration="web"></endpoint> </service> </services> <behaviors> <serviceBehaviors> <behavior name="serviceBehavior"> <serviceMetadata httpGetEnabled="true"/> <serviceDebug includeExceptionDetailInFaults="false"/> </behavior> </serviceBehaviors> <endpointBehaviors> <behavior name="web"> <webHttp/> </behavior> </endpointBehaviors> </behaviors> <protocolMapping> <add binding="basicHttpsBinding" scheme="https" /> </protocolMapping> <serviceHostingEnvironment multipleSiteBindingsEnabled="true" /> </system.serviceModel> <system.webServer> <modules runAllManagedModulesForAllRequests="true"/> <!-- To browse web app root directory during debugging, set the value below to true. Set to false before deployment to avoid disclosing web app folder information. --> <directoryBrowse enabled="true"/> </system.webServer> </configuration>
配置自己写写就明白了 此处的webHTTPBinding 是rest 服务专用的绑定模式
6)然后在浏览器中输入:http://localhost:30547/CarsRestService.svc/GetCarList/
得到的结果如下:
哈哈这样第一个rest 服务就好了,希望可以帮助到你
