关于nginx：我如何在AppHarbor上接受CORS AJAX请求？

How do I accept CORS AJAX requests on AppHarbor?

我正在使用thinkcture.identitymodel nuget包为MVC Web应用程序中的WebAPI控制器启用CORS。目前，我只担心帖子，但如果其他动词有任何问题，请告诉我。这在通过IIS Express服务器运行时有效。

在处理AppHarbor部署时，它不起作用。nginx似乎没有将选项请求传递给我的代码。在AppHarbor上运行它还需要什么？

我的web.config使用以下默认处理程序进行设置：

是WebDAV的责任吗？

在Jeffery to的建议下，我按照这些说明禁用了WebDAV。甚至不知道在啊上安装了WebDAV，但这样做确实改变了我的结果。
