Pay attention to the type of returned json data, as well as gzip?

gzip-json.go

package main
import (
	"bytes"
	"compress/gzip"
	"encoding/json"
	"fmt"
	"net/http"
	"os"
)
type poloniexData struct {
	GlobalTradeID int `json:"globalTradeID"`
	TradeID int `json:"tradeID"`
	Date string `json:"date"`
	Types string `json:"type"`
	Rate string `json:"rate"`
	Amount string `json:"amount"`
	Total string `json:"total"`
}
func main() {
// Build the request
	url := "https://poloniex.com/public?command=returnTradeHistory&currencyPair=BTC_NXT&start=1410158341&end=1410499372"
	req, _:= http.NewRequest(http.MethodGet, url, nil)
	req.Header.Add("Accept-Encoding", "gzip")
	client := new(http.Client)

	res, _ := client.Do(req)
	defer res.Body.Close()

	reader, _ := gzip.NewReader(res.Body)

	buffer := new(bytes.Buffer)
	buffer.ReadFrom(reader)

	content := buffer.Bytes()
	
	var data [] poloniexData
	json.Unmarshal(content, &data)
	fmt.Printf("Results: %v\n", data)
	os.Exit(0)
}
