I had a variable payload, it is too long here just a part.
payload := strings.NewReader("json=%7B%22rent_content_layout%22%3A%22Original%22%2C%22start_verylargetext_enabled%22%3Afalse%2C%22auto_large_mode")
is any way to make the one line var data to multi line or make it human readable using golang, for bash or shell we use \n, is any trick to line break it using golang
