Reporting services 从SharePoint 2013应用程序页调用Reporting Services API

从SharePoint 2010升级到2013时，我面临以下问题

我有一个应用程序页面，从中进行SSRSAPI调用以获取报表的所有订阅

ReportingService2010 rs = new ReportingService2010();
rs.Credentials = System.Net.CredentialCache.DefaultCredentials;
rs.Url = serverUrl + "/_vti_bin/ReportServer/ReportService2010.asmx";
try
{
    return rs.ListSubscriptions(reportUrl);
}
catch (SoapException ex)
{ }

在执行这段代码的过程中，我得到了一个带有stacktrace的UnauthorizedAccessException

我试图更改匿名身份验证的身份，但遇到了相同的异常。我已经做了大量调试，阅读了大量日志，对于如何解决这个问题，我没有任何线索。
有人能提出什么建议吗

以下是一些可能有帮助的附加信息：
Web应用程序配置为FBA，并使用LDAP提供程序进行身份验证

---

谢谢。

由于使用了FBA，设置rs.凭据没有帮助。FBA使用身份验证cookie。在

/\u vti\u bin/authentication.asmx上调用
Login
方法，然后将该cookie添加到rs连接。这里是指向类似问题的链接
您似乎需要在/_vti_bin/authentication.asmx上调用Login方法来获取身份验证cookie，然后将该cookie添加到rs连接。看看这个帖子，非常感谢！！！这对我有用。你能不能加上这个作为回答，这样我就可以接受了？
