使用DotNetOpenAuth库时出现PolicyException

dotnetopenauth asp.net

Tom Lianza · 技术社区 · 16 年前

当我将dotnetopenauth dll放到/bin目录中时,我的应用程序将不会使用以下堆栈跟踪运行。有人对这个图书馆有经验吗?我查看了他们的文档,怀疑我没有正确部署。我的Web应用程序应该在本地计算机上完全信任地运行,因此不清楚它请求的权限是什么,无法获取。

谢谢! 汤姆

奇怪的是,我发现解决方案与 this .

应用程序池标识具有属性名为“加载用户配置文件”。如果该值为假,则可以接收上面显示的错误。到解决此问题,打开IIS管理器并导航到应用程序池身份。您可以在 “高级设置”窗口。变化这是真的。

我发现当我把它设置为真时,图书馆又开始工作了。当我把它翻转回假状态时,它继续工作,即使在服务重新启动和应用程序池循环之后。奇怪的是,现在一切似乎都好起来了。

代码访问安全性似乎不考虑使用完全信任加载DotNetOpenAuth。实际上,它只需要中等信任,但下面是DotNetOpenAuth请求的最小权限列表:

[assembly: SecurityPermission(SecurityAction.RequestMinimum, Execution = true)]
[assembly: WebPermission(SecurityAction.RequestMinimum, ConnectPattern = @"http://.*")]
[assembly: WebPermission(SecurityAction.RequestMinimum, ConnectPattern = @"https://.*")]

某些中等信任配置中可能缺少第二对,但如果您以完全信任的方式运行,则应该不会出现问题。

尝试添加 <trust level="Full"/> 到其中的web.config文件 <system.web> 第节,看看这是否有帮助,或者生成一个可以帮助您缩小问题范围的错误。
