CURL-like library for golang (NOT libcurl binding)

* Custom HTTP method and header

* Monitoring download progress and speed

* Pause/resume control

### Status

[![Travis Build Status](https://travis-ci.org/nareix/curl.svg?branch=master)](https://travis-ci.org/nareix/curl)

### Usage

```go

import "github.com/nareix/curl"

req := curl.New("https://kernel.org/pub/linux/kernel/v4.x/linux-4.0.4.tar.xz")

req.Method("POST")   // can be "PUT"/"POST"/"DELETE" ...

req.Header("MyHeader", "Value")     // Custom header

req.Headers = http.Header {         // Custom all headers

	"User-Agent": {"mycurl/1.0"},

}

ctrl := req.ControlDownload()       // Download control

go func () {

	// control functions are thread safe

	ctrl.Stop()   // Stop download

	ctrl.Pause()  // Pause download

	ctrl.Resume() // Resume download

}()

req.DialTimeout(time.Second * 10)   // TCP Connection Timeout

req.Timeout(time.Second * 30)       // Download Timeout

// Print progress status per one second

req.Progress(func (p curl.ProgressStatus) {

	log.Println(

		"Stat", p.Stat,   // one of curl.Connecting / curl.Downloading / curl.Closed

		"speed", curl.PrettySpeedString(p.Speed),

		"len", curl.PrettySizeString(p.ContentLength),

		"got", curl.PrettySizeString(p.Size),

		"percent", p.Percent,

		"paused", p.Paused,

	)

}, time.Second)
