httpwrapper

httpwrapper

httpwrapper is tiny library written in Golang for serving http requests and dealing with middlewares more easier.

Installing

go get github.com/minhduccm/httpwrapper

Example

package main

import (
	"net/http"

	"github.com/minhduccm/httpwrapper"
)

func TestHandlerFunc(res http.ResponseWriter, req *http.Request) (int, error) {
	res.Write([]byte("pong 123"))
	return 200, nil
}

func BarHandlerFunc(res http.ResponseWriter, req *http.Request) (int, error) {
	res.Write([]byte("bar"))
	return 200, nil
}

func AuthFunc(next http.Handler) http.Handler {
	fn := func(w http.ResponseWriter, r *http.Request) {

		queryValues := r.URL.Query()
		key := queryValues.Get("key")
		if key != "minhduccm" {
			http.Error(w, http.StatusText(401), 401)
			return
		}
		next.ServeHTTP(w, r)
	}
	return http.HandlerFunc(fn)
}

func CustomFunc(key string) func(next http.Handler) http.Handler {
	return func(next http.Handler) http.Handler {
		fn := func(w http.ResponseWriter, r *http.Request) {

			queryValues := r.URL.Query()
			querykey := queryValues.Get("key")
			if querykey != key {
				http.Error(w, http.StatusText(401), 401)
				return
			}
			next.ServeHTTP(w, r)
		}
		return http.HandlerFunc(fn)
	}
}

func main() {
	router := httpwrapper.NewRouter()

	router.Get("/ping", httpwrapper.Perform(httpwrapper.LoggingHandler, httpwrapper.RecoveryHandler, AuthFunc, CustomFunc("minhduccm")).LeadTo(TestHandlerFunc))

	router.Get("/foo", httpwrapper.Perform().LeadTo(BarHandlerFunc))

	http.ListenAndServe(":8080", router)
}
