Question

这是我在C＃中的第一个WCF ReST服务。

Calc.svc.cs

<script src="https://apis.google.com/js/platform.js" async defer></script>
<script>
$("#google-review").click(function() {
    window.gapi.load('surveyoptin', function () {
        window.gapi.surveyoptin.render({
                "merchant_id": number,
                "order_id": order_id,
                "email": customer_email,
                "delivery_country": delivery_country,
                "estimated_delivery_date": estimated_delivery_date,
                "opt_in_style": "BOTTOM_TRAY"
            });
    });
});
</script>

ICalc.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;
        }
    }
}

服务中的Web.Config

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);
    }
}

客户的Web.Config

  <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>

在客户端.cs文件中

  <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>

错误讯息：

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

的InnerException：

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.-

调试时我收到了这条消息：

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)

http://localhost:7510/Calc.svc?wsdl

Page URL: http://localhost:7510/Calc.svc
svcutil.exe http://localhost:7510/Calc.svc?wsdl
http://localhost:7510/Calc.svc?singleWsdl

有人可以解释一下我哪个部分给了我错误。真的我不知道错误部分。它在URL中工作，但不在客户端应用程序中。

我找到了解决方案。我在Service中使用了webHttpBinding，但在客户端调用了SOAP。多数民众赞成的问题。现在我使用ReST调用客户端并解决它。

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;

WCF没有端点侦听'localhost'，错误的地址，错误（404）未找到
