Small but powerful structured logging package for HTTP request logging in Go.
(see _example/)
package main
import (
"net/http"
"github.com/go-chi/chi/v5"
"github.com/go-chi/chi/v5/middleware"
"github.com/go-chi/httplog"
)
func main() {
// Logger
logger := httplog.NewLogger("httplog-example", httplog.Options{
JSON: true,
})
// Service
r := chi.NewRouter()
r.Use(httplog.RequestLogger(logger))
r.Use(middleware.Heartbeat("/ping"))
r.Get("/", func(w http.ResponseWriter, r *http.Request) {
w.Write([]byte("hello world"))
})
r.Get("/panic", func(w http.ResponseWriter, r *http.Request) {
panic("oh no")
})
r.Get("/info", func(w http.ResponseWriter, r *http.Request) {
oplog := httplog.LogEntry(r.Context())
w.Header().Add("Content-Type", "text/plain")
oplog.Info().Msg("info here")
w.Write([]byte("info here"))
})
r.Get("/warn", func(w http.ResponseWriter, r *http.Request) {
oplog := httplog.LogEntry(r.Context())
oplog.Warn().Msg("warn here")
w.WriteHeader(400)
w.Write([]byte("warn here"))
})
r.Get("/err", func(w http.ResponseWriter, r *http.Request) {
oplog := httplog.LogEntry(r.Context())
oplog.Error().Msg("err here")
w.WriteHeader(500)
w.Write([]byte("err here"))
})
http.ListenAndServe(":5555", r)
}MIT
