rlog

rlog logs incomming HTTP requests, and provides access to a logger from HTTP request's context.Context.

rlog uses github.com/uber-go/zap as a logger implementation.

Each log record has the key requestID.

Installation

go get github.com/i-core/rlog

Usage

package main

import (
    "fmt"
    "net/http"
    "os"

    "go.uber.org/zap"
    "github.com/i-core/rlog"
)

func main() {
    // Create a logger.
    log, err := zap.NewProduction()
    if err != nil {
        fmt.Fprintf(os.Stderr, "Failed to create logger: %s", err)
        os.Exit(1)
    }

    // Create a logger middleware.
    logmw := rlog.NewMiddleware(log)

    // Wrap HTTP handler with the logger middleware.
    handler := logmw(newHandler())

    // Start a web server.
    log.Info("Server started")
    log.Fatal("Server finished", zap.Error(http.ListenAndServe(":8080", handler)))
}

func newHandler() http.Handler {
    return http.HandlerFunc(w http.ResponseWriter, r *http.Request) {
        // Get a request's logger.
        log := rlog.FromContext(r.Context())
        log.Info("Handle request")
    }
}
