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

两个猜测：你在那里有多个<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？

如果是这样，您是否有两个单独的端点地址？ 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以外的任何其他地方被调用。

从技术上讲，http和https都是http方案。

Answer 3

该问题是由IIS处理多个主机头引起的。 像blowdart这样说。 错误：此集合已包含带有方案http的地址。

在这里更详细一点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按此顺序我当然可以[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);
        }
    }

这仍然感觉很糟糕，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>

这将添加到<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

我可以通过使用Visual Studio 2013执行以下步骤来解决此问题：

1. 转到您拥有* .svc文件的项目文件夹

2. 右键单击* .svc文件 - >在浏览器中查看

3. 验证您是否能够浏览该服务

4. 转到您拥有app.config文件的项目文件夹或要使用该服务的位置。

5. 右键单击项目 - >添加 - >服务参考

6. 单击发现 - >在服务选择服务下 - >为服务引用指定所需名称 - >单击确定

7. 它将在“服务引用”文件夹下创建“ServiceReference1”并自动创建/更新app.config文件
