我想知道是否有人在使用 plesk 服务器的 Godaddy 豪华 Windows 上托管 asp.net mvc5、identity2 和 OWIN？我已遵循网上发布的所有建议，但仍然无法正常工作。我已将相同的文件放在另一台服务器上并运行 Web 应用程序。我怀疑这是一个信任级别。我已经联系了支持 Godaddy，他们说他们的服务器允许信任级别 4——这令人困惑——是中等信任还是完全信任？他们是诚实的吗？在我取消托管之前，我想知道是否有人在使用这种类型的托管

我知道这已经过时了，但我正在发布解决方案，以便其他遇到这个问题的人可以得到帮助。

您只需将完整的信任元素放在您的 web.config 中，如下所示：

<system.web>
<trust level="Full" />
</system.web>
