I need to run some custom auth code with existing services, and to do this properly, I'll need to be able intercept all incoming requests from all clients to double check some things with the other service.

推荐答案

最正确的方法是创建一个继承<一类href=\"http://msdn.microsoft.com/en-us/library/system.web.mvc.actionfilterattribute.aspx\">ActionFilterAttribute并覆盖 OnActionExecuting 方法。这可以然后在 GlobalFilters 在的Global.asax.cs

The most correct way would be to create a class that inherits ActionFilterAttribute and override OnActionExecuting method. This can then be registered in the GlobalFilters in Global.asax.cs

当然，这只会拦截，实际上有一个路由请求。

Of course, this will only intercept requests that actually have a route.
