curl2http

Description

This library parses curl arguments and able to generate corresponding http.Client and http.Request.

Why?

Modern web browsers have copy as cURL feature in development console.

To take advantage of that, CLI tools have to support cURL compatible options.

This library aims to cut the boilerplate.

Example

simple usage

package main

import (
	"io"
	"os"

	"github.com/hirochachacha/curl2http"
)

func main() {
	client, req, err := curl2http.NewRequestFromArgs(os.Args[1:])
	if err != nil {
		panic(err)
	}

	resp, err := client.Do(req)
	if err != nil {
		panic(err)
	}

	err = io.Copy(os.Stdout, resp.Body)
	if err != nil {
		panic(err)
	}
}

go run main.go curl -X POST www.example.com/post -d a=b -d c=d
