HTTP request method in context

[JianleiZhang]

I want to use the middleware casbin. Can I use the request method as the casbin action?

I add this code in transport_http.go, but I think this file should not be edited manually.

	// Tune specific change.
	// also add the request url
	ctx = context.WithValue(ctx, "request-url", r.URL.Path)
	ctx = context.WithValue(ctx, "transport", "HTTPJSON")
	ctx = context.WithValue(ctx, "method", r.Method)
