Server Hooks |
The service constructor can use hooks *twirp.ServerHooks to plug in additional
functionality:
func NewHaberdasherServer(svc Haberdasher, hooks *twirp.ServerHooks) http.HandlerThese hooks provide a framework for side-effects at important points while a request gets handled. You can do things like log requests, record response times in statsd, authenticate requests, and so on.
To enable hooks for your service, you pass a *twirp.ServerHooks in to the
server constructor. The ServerHooks struct holds a pile of callbacks, each of
which receives the current context.Context, and can provide a new
context.Context (possibly including a new value through the
context.WithValue
function).
Check out
the godoc for ServerHooks
for information on the specific callbacks. For an example hooks implementation,
github.com/twitchtv/twirp/hooks/statsd
is a good tutorial.
