Silverlight无法使用webservice Security Exception [英] Silverlight cannot use webservice Security Exception
问题描述
有人可以帮助我以下问题，我正在尝试使用Web服务来显示位于我的网站上的数据库与Mocha的记录。在我的桌面上测试时应用程序运行正常，但在线测试时出现以下错误。您可以在此处测试 http://www.viewmypurchases.com/SalesRptTestPage.html 使用两个不同的地址，它们会产生不同的错误。
System.Reflection.TargetInvocationException：操作期间发生异常，导致结果无效。 检查InnerException是否有异常详细信息。 ---> System.ServiceModel.CommunicationException：尝试向URI"http：//localhost/KIS_Mill_WebService.svc"发出请求时发生错误。这可能是由于尝试在没有适当的跨域策略的情况下以跨域方式访问服务，或者是不适合SOAP服务的策略。您可能需要联系服务的所有者以发布跨域策略文件，并确保它允许发送与SOAP相关的HTTP标头。在不使用InternalsVisibleToAttribute属性的情况下，在Web服务代理中使用内部类型也可能导致此错误。有关更多详细信息，请参阅内部异常。 ---> System.Security.SecurityException ---> System.Security.SecurityException：安全错误。

Could someone please help me with the following problem, I am trying to use a web service to display records from a database located on my website with Mocha. The application works fine when tested on my desktop but I get the following error when testing it online. You can test it here http://www.viewmypurchases.com/SalesRptTestPage.html using two different address’s which give different errors.
System.Reflection.TargetInvocationException: An exception occurred during the operation, making the result invalid. Check InnerException for exception details. ---> System.ServiceModel.CommunicationException: An error occurred while trying to make a request to URI 'http://localhost/KIS_Mill_WebService.svc'. 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 that is unsuitable for SOAP services. You may need to contact the owner of the service to publish a cross-domain policy file and to ensure it allows SOAP-related HTTP headers to be sent. This error may also be caused by using internal types in the web service proxy without using the InternalsVisibleToAttribute attribute. Please see the inner exception for more details. ---> System.Security.SecurityException ---> System.Security.SecurityException: Security error.

My Clientaccesspolicy file is as follows.
<?xml version="1.0" encoding="utf-8"?>
<access-policy>
<cross-domain-access>
<policy>
<allow-from>
<domain uri="*"/>
</allow-from>
<grant-to>
<resource path="/" include-subpaths="true"/>
</grant-to>
</policy>
</cross-domain-access>
</access-policy>
Hope this helps
