Question

这是一个带有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"

在服务器上我得到： 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，相同的代码和配置在localhost开发服务器上正常工作。我只更改端点地址和从计算机名称到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。

但是，为多个主机头配置IIS时出现“问题”，在这种情况下，您需要使用自定义工厂删除所需的所有地址。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]);
        }
    }
}

然后你会在.svc文件中使用它

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

Answer 2

两个猜测：你在那里有多个＆lt; endpoint address =“”条目。

它们可能没有相同的值，但它们可能会解析为相同的名称。

或者因为看起来你正在使用https：//，你是否在开发机器上使用http而在实时机器上使用https？

如果是，那么两者都有单独的端点地址吗？理论上你不应该这样做 - 你在http基地址上启用传输安全性，这将阻止它在除https之外的任何其他地方被调用。

技术上，http和https都是http方案。

Answer 3

问题是由IIS处理多个主机头引起的。像blowdart这样说。错误：此集合已包含方案http。

的地址

在这里稍微详细一点 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项，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，我可以做[1]，但我不喜欢这种配置依赖。

由于https绑定，我的问题似乎有点复杂，这是我提出的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);
        }
    }

仍然感觉很乱，应该由微软解决。

Answer 4

尝试在web配置中为生产服务器添加前缀：

<serviceHostingEnvironment>
  <baseAddressPrefixFilters>
    <add prefix="https://www.greenjump.nl:443" />
  </baseAddressPrefixFilters>
</serviceHostingEnvironment>

这会添加到<system.serviceModel>

您的端点应如下所示：

   <endpoint address="https://www.greenjump.nl:443/WebServices/OrderService.svc" 
              binding="wsHttpBinding"
              bindingConfiguration="wsHttps"
              contract="SharpShop.Services.IOrderService">

否则，您可以像其他评论员建议的那样重载ServiceFactory

Answer 5

我可以使用Visual Studio 2013执行以下步骤来解决此问题：

转到您拥有* .svc文件的项目文件夹
右键单击* .svc文件 - ＆gt;在浏览器中查看
验证您是否能够浏览服务
转到您拥有app.config文件的项目文件夹或您要使用该服务的位置。
右键单击项目 - ＆gt;添加 - ＆gt;服务参考
点击发现 - ＆gt;在服务选择服务下 - ＆gt;为您的服务参考提供所需的名称 - ＆gt;点击确定
它将创建＆＃34; ServiceReference1＆＃34;在文件夹＆＃34;服务参考＆＃34; ＆安培;自动创建/更新app.config文件
