实现多个服务契约的 WCF 类

Question

我有一个类 TestService，它实现了两个名为 IService1 和 IService2 的服务契约。但我在执行过程中遇到了困难。

我的代码如下所示：

Uri baseAddress = new Uri("http://localhost:8000/ServiceModel/Service");
Uri baseAddress1 = new Uri("http://localhost:8080/ServiceModel/Service1");

ServiceHost selfHost = new ServiceHost(typeof(TestService));

selfHost.AddServiceEndpoint(typeof(IService1), new WSHttpBinding(), baseAddress);
selfHost.AddServiceEndpoint(typeof(IService2), new WSHttpBinding(), baseAddress1);

ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
smb.HttpGetEnabled = true;
selfHost.Description.Behaviors.Add(smb);

selfHost.Open();
Console.WriteLine("The service is ready.");
Console.WriteLine("Press <ENTER> to terminate service.");
Console.WriteLine();
Console.ReadLine();

selfHost.Close();

我收到运行时错误：

HttpGetEnabled 属性 ServiceMetadataBehavior 设置为 true 并且 HttpGetUrl 属性是 相对地址，但是没有http 基址。要么提供一个 http 基地址或将 HttpGetUrl 设置为 绝对地址。

我能做什么呢？我真的需要两个单独的端点吗？

Answer 1

您可以通过两种方式修复它

1)

Uri baseAddress = new Uri("http://localhost:8000/ServiceModel");
ServiceHost selfHost = new ServiceHost(typeof(TestService), baseAdress);

selfHost.AddServiceEndpoint(typeof(IService1), new WSHttpBinding(), "Service");
selfHost.AddServiceEndpoint(typeof(IService2), new WSHttpBinding(), "Service1");

ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
smb.HttpGetEnabled = true;
selfHost.Description.Behaviors.Add(smb);

2)

ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
smb.HttpGetEnabled = true;
smb.HttpGetUrl = new Uri("http://localhost:8000/ServiceModel");
selfHost.Description.Behaviors.Add(smb);

Answer 2

您所需要做的就是添加基地址。
您仍然有两个独立的端点。

ServiceHost selfHost = new ServiceHost(typeof(TestService), new Uri ("http://localhost:8080/ServiceModel"));
