WCF没有端点在'localhost'侦听，地址不正确，未发现错误（404）

Question

这是我在C＃中的第一个WCF ReST服务。

Calc.svc.cs

namespace WcfService1
{
    public class Calc : ICalc
    {
        public string XMLData(string id)
        {
            return "XML product " + id;
        }

        public string JSONData(string id)
        {
            return "JSON product " + id;
        }
    }
}

ICalc.cs

namespace WcfService1
{
    [ServiceContract]
    public interface ICalc
    {
        [OperationContract]
        [WebInvoke(Method = "GET",
            ResponseFormat = WebMessageFormat.Xml,
            BodyStyle = WebMessageBodyStyle.Wrapped,
            UriTemplate = "xml/{id}")]
        string XMLData(string id);

        [OperationContract]
        [WebInvoke(Method = "GET",
            ResponseFormat = WebMessageFormat.Json,
            BodyStyle = WebMessageBodyStyle.Wrapped,
            UriTemplate = "json/{id}")]
        string JSONData(string id);
    }
}

Web.Config服务

  <system.serviceModel>
    <bindings>
      <webHttpBinding>
        <binding name="webHttpBinding_IService1" />
      </webHttpBinding>
    </bindings>

    <behaviors>
      <serviceBehaviors>
        <behavior name="ServiceBehaviour">
          <serviceMetadata httpGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="true"/>
        </behavior>
      </serviceBehaviors>
      <endpointBehaviors>
        <behavior name="webHttp">
          <webHttp helpEnabled="true"/>
        </behavior>
      </endpointBehaviors>
    </behaviors>

    <services>
      <service name="WcfService1.Calc" behaviorConfiguration="ServiceBehaviour" >
        <endpoint address="" contract="WcfService1.ICalc" 
                  binding="webHttpBinding" behaviorConfiguration="webHttp" bindingConfiguration="webHttpBinding_IService1" />
        <endpoint address="mex" contract="IMetadataExchange" binding="mexHttpBinding" />
      </service>
    </services>    

  <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
  </system.serviceModel>

客户端上的Web.Config

  <system.serviceModel>
    <bindings>
      <webHttpBinding>
        <binding name="webHttpBinding_IService1" />
      </webHttpBinding>
    </bindings>
    <behaviors>
      <endpointBehaviors>
        <behavior name="webhttp">
          <webHttp/>
        </behavior>
      </endpointBehaviors>
    </behaviors>
    <client>
      <endpoint address="http://localhost:7510/Calc.svc" contract="WcfService1.ICalc" behaviorConfiguration="webhttp" 
                binding="webHttpBinding" bindingConfiguration="webHttpBinding_IService1" />
    </client>
  </system.serviceModel>

在客户端.cs文件中

WcfService1.CalcClient cal = new CalcClient();
Label.Text = cal.XMLData("xmldata123");

错误信息：

There was no endpoint listening at http://localhost:7510/Calc.svc/XMLData that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.-

InnerException：

System.Net.WebException: The remote server returned an error: (404) Not Found. at System.Net.HttpWebRequest.GetResponse() at System.ServiceModel.Channels.HttpChannelFactory`1.HttpRequestChannel.HttpChannelRequest.WaitForReply(TimeSpan timeout)

在调试时，我收到以下消息：

谁能解释一下哪一部分给我错误。 真的我不知道错误部分。 它可以在URL中工作，但不能在客户端应用程序中工作。

Answer 1

我找到了解决方案。 我在Service中使用了webHttpBinding，但在客户端中通过SOAP进行了调用。 那就是问题。 现在，我使用ReST致电客户端并解决了该问题。

原始客户端代码（SOAP模型）

WcfService1.CalcClient cal = new CalcClient();
Label.Text = cal.XMLData("xmldata123");

使用ReST模型更新了客户端代码

        HttpClient client = new HttpClient();
        HttpResponseMessage wcfResponse = client.GetAsync(string.Format("http://localhost:7510/Calc.svc/xmlData/{0}", "hello")).Result;
        HttpContent stream = wcfResponse.Content;
        var data = stream.ReadAsStringAsync();
        Label.Text = data.Result;
