捕获asp.net mvc的所有响应。 有什么选择？

Question

I need to catch all the responses of the app. How can I do it?

With regards to the incoming requests, I can work with the HttpModule , but I need the responses.

I could create the filters, but this will also require me to assign the filter attribute to each new controller and this is what I want to avoid.

Is there another way to do it?

Assuming your application is not on ASP.NET Core, you can create module to subscribe to end request. Here you can capture response.

public class CaptureResponseModule : IHttpModule
    {
        public void Init(HttpApplication application)
        {
            application.EndRequest += (o, s) =>
            {
                var response = HttpContext.Current.Response;
                /*capture response for logging/tracing etc. */
            };
        }
        public void Dispose()
        {
            throw new NotImplementedException();
        }
    }

You need to register this module in your web.config file, something like :

 <system.web>
   <httpModules><add name="CaptureResponseModule " type="CaptureResponseModule"/></httpModules>
</system.web>
