wcf 数据服务，实现接口功能

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
