.net - 如何使用 HTTP Get 调用 WCF web 服务

Question

我想使用 url 查询字符串调用 wcf web 服务。就像我有一个公开添加两个整数的 ADD 方法的网络服务。我想使用 http://mywebserviceAddress/Add?x=4&y=5 调用此服务

这个可以吗？我是网络服务的新手，这对你们大多数人来说可能很容易。

看看下面的例子是否对你有帮助:

服务契约(Contract)

[ServiceContract] 
public interface IService1 
{ 
   [OperationContract] 
   [WebGet(UriTemplate="Add/{x}/{y}",ResponseFormat=WebMessageFormat.Xml)] 
   int Add(string x, string y); 
 }

服务实现:

public class Service1 : IService1
    {
        public int Add(string x, string y)
        {
            return Convert.ToInt32(x) + Convert.ToInt32(y);
        }
    }

网络配置:

<system.serviceModel>
        <services>
            <service name="WcfService1.Service1" behaviorConfiguration="WcfService1.Service1Behavior">
                <endpoint address="" binding="webHttpBinding" behaviorConfiguration="webBehavior" contract="WcfService1.IService1">
                    <identity>
                        <dns value="localhost"/>
                    </identity>
                </endpoint>
                <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
            </service>
        </services>
        <behaviors>
            <serviceBehaviors>
                <behavior name="WcfService1.Service1Behavior">
                    <serviceMetadata httpGetEnabled="false"/>
                    <serviceDebug includeExceptionDetailInFaults="false"/>
                </behavior>
            </serviceBehaviors>
      <endpointBehaviors>
        <behavior name="webBehavior">
          <webHttp/>
        </behavior>
      </endpointBehaviors>
        </behaviors>
    </system.serviceModel>

客户端代码:

WebRequest request = WebRequest.Create("http://localhost:2156/Service1.svc/Add/2/3");
            HttpWebResponse response = (HttpWebResponse)request.GetResponse();
            Console.WriteLine("Request to add numbers: ");
            Console.WriteLine("Request status: " + response.StatusDescription);
            Stream dataStream = response.GetResponseStream();
            StreamReader reader = new StreamReader(dataStream);
            string responseFromServer = reader.ReadToEnd();
            Console.WriteLine("Response: \n" + responseFromServer);
            Console.ReadLine();
