go-http-body

Read Golang http.Request.Body quickly and in effective way. The default way is to use io.ReadAll(r.Body) but it makes a lot of memory re-allocations and copies. Instead we can allocate a slice with Content-Lenght from beginning.

Usage

import (
	http_body "github.com/stokito/go-http-body"
)

func handleUpdateConf(w http.ResponseWriter, r *http.Request) {
	defer http_body.CloseBody(&r.Body) // safely close body even if it's nil
	if r.Method != "PUT" {
		w.WriteHeader(http.StatusMethodNotAllowed)
		return
	}
	reqBody, err := http_body.ReadHttpBody(r.Body, r.Header)
	println(string(reqBody))
	w.WriteHeader(http.StatusNoContent)
}
