无法连接到自托管WCF服务

Question

我正在尝试构建一个相当基本的WCF SOAP Web服务,作为Windows服务自托管.Windows服务本身在我的机器上启动并运行 - 我无法通过Visual Studio或Web浏览器在本地访问它.

相关的C#代码如下.假设MyDummyService实施合同IDummyService:

public class Program : ServiceBase
{
    private ServiceHost host = null;
    private readonly Uri baseAddress = new Uri("http://localhost:8000/DummyAPI");

    public static readonly ILog log = LogManager.GetLogger(typeof(Program));
    /// <summary>
    /// The main entry point for the application.
    /// </summary>
    public static void Main(string[] args)
    {
        ServiceBase.Run(new Program());
    }

    public Program()
    {
        this.ServiceName = "DummyService";
    }

    protected override void OnStart(string[] args)
    {
        log.Info("Starting service");

        try
        {
            base.OnStart(args);

            host = new ServiceHost(typeof(MyDummyService), baseAddress);

            host.Open();
        }
        catch (Exception ex)
        {
            log.Error(ex.ToString());
        }
        finally
        {
            if (host != null)
                ((IDisposable)host).Dispose();
        }
    }

    protected override void OnStop()
    {
        log.Info("Stopping service");
        base.OnStop();
        host.Close();
    }
}

相关app.config:

<system.serviceModel>
    <services>
        <service name="DummyAPI.MyDummyService" 
                 behaviorConfiguration="MyDummyBehavior">
           <endpoint 
               address="" 
               binding="basicHttpBinding" 
               contract="DummyAPI.IDummyService" />
           <endpoint address="mex" binding="mexHttpBinding" 
                     contract="IMetadataExchange" />
        </service>
    </services>
    <behaviors>
        <serviceBehaviors>
            <behavior name="MyDummyBehavior">
                <serviceMetadata httpGetEnabled="True" policyVersion="Policy15"/>
                <serviceDebug includeExceptionDetailInFaults="True"/>
            </behavior>
        </serviceBehaviors>
    </behaviors>
</system.serviceModel>

当我访问

http://localhost:8000/DummyAPI

要么

http://localhost:8000/DummyAPI/MyDummyService

(或其中任何一个后面跟着？wsdl)在网页浏览器中,我得到了404.显而易见的第一个问题:我上面有什么问题？

该web.config命名空间(或者是什么样子的命名空间)中有我有点困惑.我可以安全地在现场做些什么,以及需要反映C#类命名空间的内容是什么？

看起来您正在使用Start方法处理ServiceHost,这种方法在没有运行ServiceHost的情况下有效地离开了您.

finally
{
    if (host != null)
        ((IDisposable)host).Dispose();
}
