在 IIS 下为 WCF 托管多个主机

Question

我需要在 IIS 下使用多个主机进行 WCF。 我们正在使用 wshttpbinding，即使在 stackoveflow 上检查了几个类似的问题后，我们仍然没有发现任何成功。

这是我的 web.config

这是我的服务工厂类

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();
            }
        }

    }
}

Service1.svc 文件的内容

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

可能有什么问题？

将不胜感激任何帮助。

谢谢。

Answer 1

尝试一下，看看它是否有效（我真的不确定它是否适用于两个地址，但可能）：

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);
}

看起来您没有启用传输安全性，因此假设“http://”可能是安全的，但如果您需要打开它，则必须修改代码才能将 https:// 放入其中。

Answer 2

嘿，将其添加到您的 配置部分中

<serviceHostingEnvironment aspNetCompatibilityEnabled="true" />

，

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

并将 using System.ServiceModel.Activation; 添加到您的代码中，

我也遇到了同样的问题。
