WCF和Silverlight的crossdomain.xml [英] WCF and Silverlight CrossDomain.xml

问题描述

道歉，如果这已经被问过（我无法找到答案的任何地方），但我有我创建了一个WCF服务应用程序，并正尝试通过我的Silverlight 4应用程序来访问。我已经添加了服务引用Silverlight应用程序和我只是想调用的服务（的GetData）的默认pre现有的方法之一。当调用该方法，我得到了一个错误：

Apologies if this has been asked before (I couldn't find the answer anywhere), but I have a WCF Service Application that I have created, and am trying to access via my Silverlight 4 app. I have added the service reference to the SilverLight App and am just trying to call one of the default pre existing methods on the service (GetData). When calling the method i get an error of:

而努力使出错   请求URI我的URI这可能   是由于试图访问   在未经跨域方式服务   有了适当的跨域策略，   或政策文件，是不合适的   对SOAP服务。

An error occurred while trying to make a request to URI "my URI" This could be due to attempting to access a service in a cross-domain way without a proper cross-domain policy in place, or a policy file that is unsuitable for SOAP Services.

我知道我需要一个crossdomain.xml文件，但它不似乎无论身在何处我把crossdomain.xml文件，我仍然得到错误，这是该文件的内容：

I'm aware I need a crossdomain.xml file, but it doesnt seem to matter where i place the crossdomain.xml file, i still get the error, this is the contents of the file:

  <?xml version="1.0" encoding="utf-8"?>
  <access-policy>
     <cross-domain-access> 
       <policy>
         <allow-from http-request-headers="SOAPAction"> 
          <domain uri="http://*"/> 
          <domain uri="https://*" />  
         </allow-from>
        <grant-to>
           <resource include-subpaths="true" path="/"/>
        </grant-to> 
       </policy>
     </cross-domain-access>
  </access-policy>

任何想法？

推荐答案

它确实身在何处，您将策略文件 - 它需要被放置在根这是运行服务的Web服务器

It does matter where you place the policy file - it needs to be placed "at the root" of the web server that's running your service.

这是pretty的有据可查了在 HTTP： //msdn.microsoft.com/en-us/library/cc197955(VS.95).aspx

That's pretty well documented up at http://msdn.microsoft.com/en-us/library/cc197955(VS.95).aspx

在这些问题上我最好的建议是运行Fiddler工具和跟踪流量，你应该看到的Silverlight寻找一个clientaccesspolicy.xml的文件（也是crossdomain.xml文件这是一种不同的格式），而且应使容易确定何处Silverlight的被查找的文件

My best advice on these issues is to run the Fiddler tool and trace the traffic and you should see Silverlight looking for a clientaccesspolicy.xml file (and also the crossdomain.xml file which is a different format) and that should make it easier to determine where Silverlight is looking for the file.
