如何在asp.net的Windows服务中调用WCF RESTful服务? [英] How to invoke WCF RESTful Service in Windows Service in asp.net?

问题描述

我已经在WCF RESTfule服务中为POST方法创建了以下操作合同.

I have created below Operation Contract for POST Method in WCF RESTfule Service.

IService1.cs:-

[OperationContract]
[WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json, UriTemplate = "/SaveCustomerPost",
 BodyStyle = WebMessageBodyStyle.Wrapped)]
  string SaveCustomerDetails(CustomerDetails objCustomerDetails);  

[DataContract]
public class CustomerDetails
{
  [DataMember]
  public string Name { get; set; }      
}

Windows服务:-

using (WebChannelFactory<ServiceReference1.IService1> cf = new WebChannelFactory<ServiceReference1.IService1>(new Uri("http://xxx/CustomerService.svc/SaveCustomerPost")))
{
   var helloService = cf.CreateChannel();
   ServiceReference1.CustomerDetails objCustomerDetails = new ServiceReference1.PANNoDetails();
   objPANNoDetails.Name = "TestName";           
   string strResult = helloService.SaveCustomerDetails(objPANNoDetails);
}

客户端App.config:-

<system.serviceModel>
    <behaviors>
      <endpointBehaviors>
        <behavior name="CustBehavior">
          <webHttp />
        </behavior>
      </endpointBehaviors>
    </behaviors>
    <bindings>
      <webHttpBinding>
        <binding name="WebHttpBinding" sendTimeout="00:05:00" maxBufferSize="2147483647"
          maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647"
          transferMode="Streamed">
          <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647"
            maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
          <security mode="None" />
        </binding>
      </webHttpBinding>
    </bindings>
    <client>
      <endpoint address=""
          binding="webHttpBinding" behaviorConfiguration="CustBehavior"
          contract="ServiceReference1.ICustService" name="WebHttpBinding" />
    </client>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true"
      multipleSiteBindingsEnabled="true" minFreeMemoryPercentageToActivateService="0"/>
  </system.serviceModel>

在"xxx.svc/SaveCustomerDetails"上没有侦听终结点的端点可以接受该消息.这通常是由不正确的地址或SOAP操作引起的.有关更多详细信息，请参见InnerException(如果存在).

当我在窗口服务中使用WebInvoke方法调用上述方法时，出现了上述错误.当我在没有WebInvoke方法的情况下调用上述服务 时，该服务运行正常.如何解决上述问题?

When I invoke above mentioned method with WebInvoke method in window service I got above mentioned error. When I invoke above mentioned service without WebInvoke method, service is working fine. How to resolve above mentioned issue?

推荐答案

在创建 ChannelFactory 时，尝试仅指定服务名称:

When creating the ChannelFactory, try to specify the service name only:

using (ChannelFactory<ServiceReference1.ICustService> factory = new ChannelFactory<ServiceReference1.ICustService>(
    new WebHttpBinding(),
    "http://xxx/CustomerService.svc"))
{
}
