silverlight - 跨域错误

Question

我在 IIS 中托管了我的 Silverlight 应用程序，现在当我尝试访问该应用程序时出现以下错误

System.ServiceModel.CommunicationException: an error occured while trying to make request to URI This could be due to attempting to access a service in a cross-domain way without proper cross-domain policy in place, or policy that is unsuitable for SOAP services.....

我已将跨域策略正确放置在 wwwroot 以及虚拟目录中。

<?xml version="1.0"?>

<cross-domain-policy>
  <allow-http-request-headers-from domain="*" headers="*"/>
</cross-domain-policy>

如果您不需要与安全策略与 Flash 兼容，请尝试使用 Silverlight 特定的 clientaccesspolicy.xml 并查看是否出现相同的错误。退房 Tim Heuer's blog post关于对文件位置错误进行故障排除(如果仍有问题)

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