func Middleware ¶

func Middleware(tr opentracing.Tracer, h http.Handler, options ...nethttp.MWOption) http.Handler

Middleware wraps an http.Handler and traces incoming requests. Additionally, it adds the span to the request's context.

By default, the operation name of the spans is set to "HTTP {method}". This can be overriden with options.

The options allow fine tuning the behavior of the middleware.

Example:

pattern := "/api/custerms/{id}"
mw := gorilla.Middleware(
   tracer,
   handler,
)
r := mux.NewRouter()
r.HandleFunc(pattern, mw)
