Размещение нескольких хостов под IIS для WCF

/ 10 сентября 2009

Мне нужно использовать несколько хостов под IIS для WCF. Мы используем wshttpbinding и до сих пор не добились успеха даже после того, как проверили пару похожих вопросов о stackoveflow.

Вот мой web.config

Вот мой сервис фабричного класса 

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.ServiceModel;
using System.ServiceModel.Activation;

namespace WcfService1
{
    public class CustomHostFactory : ServiceHostFactory 

    {
        protected override ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses)
        {
            //CustomHost customServiceHost =
            //  new CustomHost(serviceType, baseAddresses[1]);
            //return customServiceHost;
            ServiceHost host;

            host = new ServiceHost(serviceType, baseAddresses[0]);

            return host;

        }
        class CustomHost : ServiceHost
        {
            public CustomHost(Type serviceType, params Uri[] baseAddresses)
                : base(serviceType, baseAddresses)
            { }
            protected override void ApplyConfiguration()
            {
                base.ApplyConfiguration();
            }
        }

    }
}

Содержимое моего файла Service1.svc 

<%@ ServiceHost Language="C#" Debug="true" Service="WcfService1.Service1" CodeBehind="Service1.svc.cs" Factory="WcfService1.CustomHostFactory" %>

Что может быть не так?

Буду признателен за любую помощь.

Спасибо.

Попробуйте и посмотрите, работает ли он (я действительно не уверен, что он будет работать для обоих адресов, но это возможно): 

protected override System.ServiceModel.ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses)
{
    if (HttpContext.Current != null)
    {
        string baseAddress = string.Format("http://{0}{1}{2}", HttpContext.Current.Request.Url.Host, HttpContext.Current.Request.Url.Port == 80 ? "" : ":" + HttpContext.Current.Request.Url.Port, HttpContext.Current.Request.CurrentExecutionFilePath);
        Uri baseURI = new Uri(baseAddress);
        return base.CreateServiceHost(serviceType, new Uri[] { baseURI });
    }

    //We did the best we could, but there is no current HTTP request.
    //Just fall back to the base service host factory
    return base.CreateServiceHost(serviceType, baseAddresses);
}

Не похоже, что у вас включена защита транспорта, поэтому предположим, что "http://", вероятно, безопасно, но если вам нужно включить это, вам придется поработать с кодом, чтобы получить http s : // там.

Эй, добавь это в свой <system.serviceModel> раздел конфигурации 

<serviceHostingEnvironment aspNetCompatibilityEnabled="true" />

и 

[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class yourService : IyourService
{ ..... }

добавить using System.ServiceModel.Activation; к вашему коду

У меня тоже была такая же проблема.
