wcf服务无法激活

Question

它是一个带有ssl和成员资格的.svc IIS托管服务.

我的wcf客户报告:

System.ServiceModel.ServiceActivationException was unhandled
  Message="The requested service, 'https://www.greenjump.nl/WebServices/OrderService.svc' could not be activated. See the server's diagnostic trace logs for more information."
  Source="mscorlib"

在我得到的服务器上:System.ArgumentException此集合已包含方案http的地址.此集合中每个方案最多只能有一个地址.参数名称:item

奇怪的是,这只发生在生产服务器上,localhost开发服务器上的相同代码和配置工作正常.我只更改端点地址,并从计算机名称更改为www.webdomain.com

Answer 1

如果您在IIS中托管,则不需要基本地址部分 - 因为它是提供它的IIS的站点配置 - 因此请删除该部分.

虽然为多个主机头配置了IIS,但存在"问题",在这种情况下,您需要使用自定义工厂删除除所需地址之外的所有地址.一个简单的例子是

namespace Example
{
    public class GenericServiceHostFactory : ServiceHostFactory
    {
        protected override ServiceHost CreateServiceHost(Type serviceType, 
                                                         Uri[] baseAddresses)
        {
            //return the first...
            return new ServiceHost(serviceType, baseAddresses[0]);
        }
    }
} 

然后,您将在.svc文件中使用它

<%@ ServiceHost 
    Service="MyImplementationClass"
    Factory="Example.GenericServiceHostFactory"
%>

Answer 2

该问题是由 IIS 处理多个主机标头引起的。就像吹镖在这里所说的那样。错误：此集合已包含方案为 http 的地址。

这里更详细一些 http://forums.silverlight.net/forums/p/12883/274592.aspx

使用第一个baseAddresses [0]对我来说不是一个选择，因为我的baseAddresses是 http://localhost/WebServices/OrderService.svc http://www.greenjump.nl/WebServices/OrderService.svc https://vps2051.xlshosting .net/WebServices/OrderService.svc 按照这个顺序当然我可以做[1]，但我不喜欢这种配置依赖性。

由于 https 绑定，我的问题似乎更加复杂，这是我想出的 ServiceHostFactory：

 public class MyServiceHostFactory : ServiceHostFactory
    {

        protected override ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses)
        {
            Uri webServiceAddress = baseAddresses[0]; //default to first

            if (HttpContext.Current != null) //this only works when aspNetCompatibilityEnabled=true
            {
                string host = HttpContext.Current.Request.Url.Host;
                var goodAddress = baseAddresses.FirstOrDefault(a => a.Host == host);//try to find address with same hostname as request
                if(goodAddress!=null)
                {
                    webServiceAddress = goodAddress;
                }
                Type[] sslServices = { typeof(OrderService)  };//add all https services here
                if (sslServices.Any(s => s == serviceType))
                {
                    UriBuilder builder = new UriBuilder(webServiceAddress);
                    builder.Scheme = "https";
                    builder.Port = 443; //fails if you use another port
                    webServiceAddress = builder.Uri;
                }
            }
            return new ServiceHost(serviceType, webServiceAddress);
        }
    }

不过这感觉还是很奇怪，应该由微软来解决。
