Question

我有一个应该托管服务的应用程序。该服务正在实施Interface喜欢这个：

    [ServiceContract]
    public interface IRegistrationCaseFetcherService
    {
        [OperationContract]
        bool CancelTransaction(string transactionControlNumber);

        [OperationContract]
        bool ConfirmTransaction(string transactionControlNumber);

        [OperationContract]
        bool UpdateTransaction(string transactionControlNumber, UpdatedRegistrationCase personData);

        [OperationContract]
        bool checkEndPoint();
    }

我的服务定义如下：

    [ServiceBehavior(UseSynchronizationContext = false)]
    public class RegistrationCaseFetcherService : IRegistrationCaseFetcherService
    {
        static int CallsInProgress = 0;

        public bool CancelTransaction(string transactionControlNumber)
        {
            return true;
        }

        public bool ConfirmTransaction(string transactionControlNumber)
        {
            return true;
        }

        public bool UpdateTransaction(string transactionControlNumber, UpdatedRegistrationCase personData)
        {
            return true;
        }

        public bool checkEndPoint()
        {
            return true;
        }


        public static bool IsInUse
        {
            get
            {
                return (CallsInProgress != 0);
            }
        }
    }

我也有一个类来触发这项服务：

  public static class Services
  {
            private static ServiceHost _service;
            private static bool _isHosted = false;

            public static bool StartRecieveService()
            {
                var address = string.Format("http://{0}:8732/Services/RService", Dns.GetHostName());

                _service = new ServiceHost(typeof(RegistrationCaseFetcherService), new Uri(address));
                _service.AddServiceEndpoint(typeof(IRegistrationCaseFetcherService), new BasicHttpBinding(), address);

                var serviceMetaDataBehaviour = _service.Description.Behaviors.Find<ServiceMetadataBehavior>();
                if (serviceMetaDataBehaviour == null) serviceMetaDataBehaviour = new ServiceMetadataBehavior();
                serviceMetaDataBehaviour.HttpGetEnabled = true;
                serviceMetaDataBehaviour.MetadataExporter.PolicyVersion = PolicyVersion.Policy15;

                _service.Description.Behaviors.Add(serviceMetaDataBehaviour);

                try
                {
                    _service.Open();
                    _isHosted = true;
                    if (_service.BaseAddresses.Count > 0)
                        _logger.Trace(String.Format("Waiting for incomming calls on: {0}", _service.BaseAddresses[0].AbsoluteUri));
                    return true;
                }
                catch (Exception e)
                {
                    _logger.Error("Failed with exception: " + e);
                    return false;
                }
            }
        }

我调试时似乎正在触发服务，不会抛出任何异常。通过在我的Web浏览器中打开URL无法正常工作，它表示资源不存在。我也尝试在WCF Test Client中打开它，但后来我得到Error: Cannot Obtain Metadata。

如何才能真正验证我的服务已启动并正常运行？我的代码应该做些什么改变才能让它工作？

提前致谢

您需要添加至少一个端点（此处为http为＆＃34; wsdl＆＃34;），其中公开了元数据：

_service.AddServiceEndpoint(ServiceMetadataBehavior.MexContractName,
    MetadataExchangeBindings.CreateMexHttpBinding(),
    "mex");
