*读者小心：大量代码转储，不适合心脏... *CrossDomainError在IIS7的Silverlight 3 WCF应用
你好微弱，
我试图找出如何部署带有WCF服务的IIS7 Silverlight 3应用程序。我想我已经找到了大部分，但是由于某种原因，我仍然遇到了跨域错误。我倾向于认为该服务没有找到客户端访问策略，但我不知道如何确认。我得到一个非常无用的例外（简单地说，CrossDomainError）。内部异常是不存在的。以下是我部署应用的步骤。如果有人看到任何不能加起来的东西，他们可以提供建议吗？我想不出别的在现在捅......
- 在IIS管理器中我建立了一个新的网站。我将它命名为Silverlight，接受了同名的游戏池，并接受了其余的默认设置。我禁用了默认网站。我将Web根设置为C：\ WebApps
- 我将Visual Studio Silverlight客户端项目的发布版本中的所有文件放入Web根目录中。
- 我将Silverlight客户端项目中的以下配置文件放在Web根目录中：ServiceReferences.ClientConfig，Silverlight.js。
- 我放在/ bin目录从Silverlight.Web项目的发布版本到网站根
- 我把从Silverlight.Web发布版本的以下文件在网站根目录：crossdomain.xml的，clientaccesspolicy.xml ，Service1.svc，Service1.svc.cs，Web.config。
- 我将TestPage.html文件重命名为index.html。
我意识到很多这些都是多余的，但我没有办法尝试，所以我开始添加任何看起来可能包含任何有用元数据的东西。
下面是代码，以我的各种配置文件：
clientaccesspolicy.xml：
<?xml version="1.0" encoding="utf-8" ?>
<access-policy>
<cross-domain-access>
<policy>
<allow-from http-request-headers="*">
<domain uri="*"/>
</allow-from>
<grant-to>
<resource include-subpaths="true" path="/"/>
</grant-to>
</policy>
</cross-domain-access>
</access-policy>
的crossdomain.xml：
<!DOCTYPE cross-domain-policy SYSTEM "http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
<allow-http-request-headers-from domain="*" headers="*"/>
</cross-domain-policy>
system.serviceModel配置，节录来自Web.config：
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior name="SilverlightApplication2.Web.Service1Behavior">
<serviceMetadata httpGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="false"/>
</behavior>
</serviceBehaviors>
</behaviors>
<bindings>
<customBinding>
<binding name="customBinding0">
<binaryMessageEncoding/>
<httpTransport/>
</binding>
</customBinding>
</bindings>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true"/>
<services>
<service behaviorConfiguration="SilverlightApplication2.Web.Service1Behavior" name="SilverlightApplication2.Web.Service1">
<endpoint address="http://win-xqawq222tag:2721/Service1.svc" binding="customBinding" bindingConfiguration="customBinding0" contract="SilverlightApplication2.Web.Service1"/>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
</service>
</services>
</system.serviceModel>
ServiceReferences.ClientConfig：
<configuration>
<system.serviceModel>
<bindings>
<customBinding>
<binding name="CustomBinding_Service1">
<binaryMessageEncoding />
<httpTransport maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" />
</binding>
</customBinding>
</bindings>
<client>
<endpoint address="http://win-xqawq222tag:2721/Service1.svc" binding="customBinding"
bindingConfiguration="CustomBinding_Service1" contract="ServiceReference1.Service1"
name="CustomBinding_Service1" />
</client>
</system.serviceModel>
</configuration>
Service1.svc：
<%@ ServiceHost Language="C#" Debug="true" Service="SilverlightApplication2.Web.Service1" CodeBehind="Service1.svc.cs" %>
现在的执行，然后客户端代码：
Service1.svc 。CS：
using System;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Activation;
using System.Collections.Generic;
using System.Text;
namespace SilverlightApplication2.Web
{
[ServiceContract(Namespace = "")]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class Service1
{
[OperationContract]
public DoWorkResult DoWork()
{
// Add your operation implementation here
int i = new Random().Next();
string s = "test string";
DoWorkResult r = new DoWorkResult() { String = s, Integer = i };
return r;
}
// Add more operations here and mark them with [OperationContract]
}
[DataContract]
public class DoWorkResult
{
[DataMember]
public string String { get; set; }
[DataMember]
public int Integer { get; set; }
}
}
MainPage.xaml.cs中：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
namespace SilverlightApplication2
{
public partial class MainPage : UserControl
{
public MainPage()
{
InitializeComponent();
ServiceReference1.Service1Client proxy = new SilverlightApplication2.ServiceReference1.Service1Client();
proxy.DoWorkCompleted += new EventHandler<SilverlightApplication2.ServiceReference1.DoWorkCompletedEventArgs>(proxy_DoWorkCompleted);
proxy.OpenAsync();
proxy.DoWorkAsync();
proxy.CloseAsync();
}
void proxy_DoWorkCompleted(object sender, SilverlightApplication2.ServiceReference1.DoWorkCompletedEventArgs e)
{
if (e.Error == null)
{
String.Text = "Test String is: " + e.Result.String;
Integer.Text = "Random Int is: " + e.Result.Integer;
}
else
{
String.Text = e.Error.Message + e.Error.InnerException.Message + e.Error.StackTrace;
Integer.Text = e.Error.Message + e.Error.InnerException.Message + e.Error.StackTrace;
}
}
}
}
所有这一切都在2008年VS上XP专业版能正常工作。在Server2008上的IIS7上，我可以在http://localhost或http://[myComputerName]上点击默认页面index.html。
我也能够打http://localhost/Service1.svc服务。我无法使用http://[compNameHere]/Service1.svc进行服务。它抱怨此错误：

而且，我可以打政策文件在http://localhost/clientaccesspolicy.xml和http://[computerNameHere]/clientaccesspolicy.xml。
还有什么我需要看看？
更新：删除端口：CONFIGS 2721让我打从HTTP服务：///Service1.svc，但是我仍然无法从Silverlight应用程序中获得服务。 –
