wcf 数据服务，实现接口功能

来源：互联网发布：淘宝店铺装修基础版编辑：程序博客网时间：2024/05/22 12:18

如果搜百度的话，是这么解释的：

Windows Communication Foundation(WCF)是由微软开发的一系列支持数据通信的应用程序框架，可以翻译为Windows 通讯开发平台。

整合了原有的windows通讯的 .net Remoting，WebService，Socket的机制，并融合有HTTP和FTP的相关技术。

但是这篇文章介绍一下在wcf中如何使用get，post。

1、服务端：

首先在webconfig中进行改变：

<system.serviceModel>    <bindings>      <webHttpBinding>        <binding name="webbinding"></binding>      </webHttpBinding>    </bindings>    <services>      <service name="Wcf1.Service1" behaviorConfiguration="testserviceBehavior">        <endpoint address="" behaviorConfiguration="WebBehavior" binding="webHttpBinding" bindingConfiguration="webbinding" contract="Wcf1.IService1">        </endpoint>      </service>    </services>    <behaviors>      <serviceBehaviors>        <behavior name="testserviceBehavior">          <!-- 为避免泄漏元数据信息，请在部署前将以下值设置为 false -->          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>          <!-- 要接收故障异常详细信息以进行调试，请将以下值设置为 true。在部署前设置为 false 以避免泄漏异常信息 -->          <serviceDebug includeExceptionDetailInFaults="true"/>        </behavior>      </serviceBehaviors>      <endpointBehaviors>        <behavior name="WebBehavior">          <webHttp/>        </behavior>      </endpointBehaviors>    </behaviors>    <protocolMapping>        <add binding="basicHttpsBinding" scheme="https" />    </protocolMapping>        <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />  </system.serviceModel>

这里面进行改变的内容包括：services，behavior，endpointBehaviors

后台代码：

IService1.cs

     // 注意: 使用“重构”菜单上的“重命名”命令，可以同时更改代码和配置文件中的接口名“IService1”。    [DataContractFormat]    [ServiceContract]    public interface IService1    {       [WebGet(UriTemplate = "/Service/GetData/{name}", BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Json)]        [OperationContract]        string GetData(string name);        [WebInvoke(Method = "POST", UriTemplate = "/Service/GetDataUsingDataContract", BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Json)]        [OperationContract]        CompositeType GetDataUsingDataContract(CompositeType composite);        // TODO: 在此添加您的服务操作    }

Service1.svc.cs中

 public class Service1 : IService1    {        public string GetData(string name)        {            return string.Format("You entered: {0}", name);        }        public CompositeType GetDataUsingDataContract(CompositeType composite)        {            if (composite == null)            {                throw new ArgumentNullException("composite");            }                           composite.StringValue += "Suffix";                composite.Name += "123";                      return composite;        }    }

单独封装了一个类CompositeType.cs

 [DataContract]    public class CompositeType    {        [DataMember]        public string StringValue        {            get;            set;        }        [DataMember]        public string Name        {            get;            set;        }        bool boolValue = true;        string stringValue = "Hello ";    }

2、客户端（新建的一个一般处理程序）：

Program中是这么写的

 static void Main(string[] args)        {            var rc = new Client("http://localhost:13048//Service1.svc");            var uriget = string.Format("Service/GetData/{0}", "yatou");            string retget = rc.get(uriget);            Console.WriteLine(retget);            const string uripost = "Service/GetDataUsingDataContract";            string postdata = "{\"StringValue\":\"my name is zhangyatoua!\",\"Name\":\"yatou\"}";            //const string postdata = "<CompositeType xmlns=\"http://rest-server/datacontract/CompositeType\"><StringValue>LV</StringValue></CompositeType>";            var retpost = rc.Post(uripost, postdata);            //var retpost = rc.JiekouPost();            Console.WriteLine(retpost);            Console.ReadLine();        }

封装了一个单独的类Client.cs

public class Client    {       public Client(string baseuri)       {           _baseUri = baseuri;       }       private readonly string _baseUri;       public string get (string uri)       {           var serverurl = string.Format("{0}/{1}", _baseUri, uri);           var myRequest = (HttpWebRequest)WebRequest.Create(serverurl);           string returnstr;           using (var myResponse=(HttpWebResponse)myRequest.GetResponse())           {               using(var sr=new StreamReader(myResponse.GetResponseStream(),Encoding.UTF8))               {                   returnstr = HttpUtility.UrlDecode(sr.ReadToEnd());                   sr.Close();               }               myResponse.Close();           }           return returnstr;       }       public string Post(string uri,string data)       {           var serverurl = string.Format("{0}/{1}", _baseUri, uri);           var myRequest = (HttpWebRequest)WebRequest.Create(serverurl);           var buf = Encoding.UTF8.GetBytes(data);           myRequest.Method = "POST";           myRequest.ContentLength = buf.Length;           myRequest.ContentType = "text/json";           using (var stream = myRequest.GetRequestStream())           {               stream.Write(buf, 0, buf.Length);               stream.Close();           }           string returnstr;           HttpWebResponse response;           try           {               response = (HttpWebResponse)myRequest.GetResponse();           }           catch (WebException ex)           {               response = (HttpWebResponse)ex.Response;           }           // ReSharper disable once AssignNullToNotNullAttribute           using (var sr = new StreamReader(response.GetResponseStream()))           {               returnstr = sr.ReadToEnd();           }           return returnstr;       }    }

运行结果如下：

第一行是get得到的，第二行是post得到的
