How to Intercept all Nancy requests

问题

I have seen this post: Nancy: how do I capture all requests irrespective of verb or path and followed along on the github article.

But it does not work. I have simply added a class in my project:

 public class MyBootstrapper : Nancy.DefaultNancyBootstrapper

But this class is never instantiated, and the github documentation does not discuss this in any detail.

What do I need to do to cause my bootstrapper to be used?

回答1:

I found it. There are two ways to add items to the pipeline. One by deriving a Bootstrap class, which failed for me. The other by implementing a class which honored the IApplicationStartup interface. That worked, and here is the code:

  public class BeforeAllRequests : IApplicationStartup
{
    public void Initialize(IPipelines pipelines)
    {
        pipelines.BeforeRequest.AddItemToStartOfPipeline(ctx => {
            if (ctx != null)
            {
                Log.Debug("Request: " + ctx.Request.Url);
            }
            return null;
        });
    }
}

This worked for me (4 years later, maybe the Wiki changed since then): Bootstrapper
