使用Go语言调用币安 API进行数据获取或交易操作。

package main
import (
	"encoding/json"
	"fmt"
	"net/http"
	"time"
)
type MarketData struct {
	Symbol     stringjson:"symbol"
	Ticker     stringjson:"ticker"
	Price      float64json:"price"
	Volume     float64json:"volume"
	High         float64json:"high"
	Low          float64json:"low"
	Open24Hr    float64json:"open24hr"
}
func main() {
	apiKey := "your_api_key"
	apiSecret := "your_api_secret"
	// 创建HTTP客户端
	client := &http.Client{}
	// 定义请求URL
	url := fmt.Sprintf("https://api.binance.com/api/v3/ticker/price?symbol=USDTBTC")
	// 创建POST请求
	req, err := http.NewRequest("GET", url, nil)
	if err != nil {
		fmt.Println("Error creating request:", err)
		return
	}
	// 设置请求头
	req.Header.Set("Content-Type", "application/json")
	req.Header.Set("X-MBX-APIKEY", apiKey)
	req.Header.Set("X-MBX-SIGNATURE", generateSignature(url, req, apiSecret))
	// 发送请求
	resp, err := client.Do(req)
	if err != nil {
		fmt.Println("Error sending request:", err)
		return
	}
	defer resp.Body.Close()
	// 解析响应
	var marketData MarketData
	err = json.NewDecoder(resp.Body).Decode(&amp;marketData)
	if err != nil {
		fmt.Println("Error decoding response:", err)
		return
	}
	// 输出结果
	fmt.Printf("Symbol: %s\nTicker: %s\nPrice: %.2f USD\nVolume: %.2f\nHigh: %.2f\nLow: %.2f\nOpen24Hr: %.2f\n",
		marketData.Symbol, marketData.Ticker, marketData.Price, marketData.Volume, marketData.High, marketData.Low, marketData.Open24Hr)
}
// 生成签名函数
func generateSignature(url string, req *http.Request, secret string) string {
	timestamp := time.Now().UnixNano()
	message := timestamp + url + req.Method + req.URL.Path + req.Form.Encode()
	hash := hmac.New(sha256.New, []byte(secret))
	hash.Write([]byte(message))
	return base64.StdEncoding.EncodeToString(hash.Sum(nil))
}
