无法使用“添加服务参考”生成自托管服务的代理

Question

我创建了一个名为MiniCalc的基本计算器服务，该服务只有两个操作。添加和Mul，并将其托管在控制台应用程序中。

using(ServiceHost host = new ServiceHost(typeof(MiniCalcService.Service), 
             new Uri("http://localhost:8091/MiniCalcService"))) 
{ 
    host.AddServiceEndpoint(typeof(MiniCalcService.IService), 
          new BasicHttpBinding(), 
          "Service"); 
    host.Open(); 
    Console.Write("Press ENTER key to terminate the MiniCalcHost . . . "); 
} 

然后创建了一个控制台应用程序来消费服务和通过创建一个代理类手动创建的代理，然后创建的ChannelFactory来调用服务。

EndpointAddress ep = new EndpointAddress("http://localhost:8091/MiniCalcService/Service"); 
IService proxy = ChannelFactory<IService>.CreateChannel(new BasicHttpBinding(),ep); 

我能够正确调用服务契约并按预期检索结果。

现在我想使用Add Service Reference创建代理。

我收到以下错误，当我在添加服务引用窗口

There was an error downloading 'http://localhost:8091/MiniCalcService/Service'. 
The request failed with HTTP status 400: Bad Request. 
Metadata contains a reference that cannot be resolved: 'http://localhost:8091/MiniCalcService/Service'. 
Content Type application/soap+xml; charset=utf-8 was not supported by service http://localhost:8091/MiniCalcService/Service. The client and service bindings may be mismatched. 
The remote server returned an error: (415) Cannot process the message because the content type 'application/soap+xml; charset=utf-8' was not the expected type 'text/xml; charset=utf-8'.. 
If the service is defined in the current solution, try building the solution and adding the service reference again. 

我缺少什么或者做错了点击Go？

在您的ServiceHost中启用元数据交换行为。

using(ServiceHost host = new ServiceHost(typeof(MiniCalcService.Service), 
          new Uri("http://localhost:8091/MiniCalcService"))) 
{ 
    host.AddServiceEndpoint(typeof(MiniCalcService.IService), 
          new BasicHttpBinding(), 
          "Service"); 

    //Enable metadata exchange 
    ServiceMetadataBehavior smb = new ServiceMetadataBehavior(); 
    smb.HttpGetEnabled = true; 
    host.Description.Behaviors.Add(smb); 

    host.Open(); 
    Console.Write("Press ENTER key to terminate the MiniCalcHost . . . "); 
}

既然你没有.SVC我想你一定在你的服务的.config有这样的：

<serviceHostingEnvironment multipleSiteBindingsEnabled="true"> 
     <serviceActivations> 
      <add relativeAddress="Service.svc" service="MiniCalcService.Service" /> 
     </serviceActivations> 
    </serviceHostingEnvironment> 

之后，你需要一个选项，允许服务元数据：

<serviceMetadata httpGetEnabled="true" /> 

这有点复杂所以我劝你tu创建一个新的WCF S在一个新的解决方案中，你可以看到这个配置是怎样的。所以你只需要做一些复制/粘贴配置。

该点之后：

http://localhost:8091/MiniCalcService/Service.svc
