func main() {
	arg := "nekosasa"

	params, _ := json.Marshal(Slack{ //json形式のbinary 数字がいっぱい並んでる

		fmt.Sprintf("%s", arg),
		"arigatou",
		"dossy_bot",
		"http://www.icons101.com/icons/66/NuoveXT_by_Alexandre_Moore/128/slackware.png",
		"#test"})
	//paramsがjson形式の[]uint8のbinary string(params)で中身は見れる
	resp, _ := http.PostForm( //postを整形して実行まで行う
		IncomingUrl,
		url.Values{"payload": {string(params)}},
	)

	body, _ := ioutil.ReadAll(resp.Body)
	//ioutil.Readallはerrがないか確認するもの
	defer resp.Body.Close()
	//respはreadしたらちゃんとcloseすべきである

	println(string(body)) //err == nilならreturn ok
}

ほぼ自分用
