英文:
get element from array from response
问题
我想从HTTP响应中获取数组的第二个元素，但我不明白如何做。
// 发送GET请求
response, error := http.Get("https://api.binance.com/api/v3/klines?symbol=ETHUSDT&interval=5m&limit=5")
if error != nil {
fmt.Println(error)
}
// 读取响应体
body, error := ioutil.ReadAll(response.Body)
if error != nil {
fmt.Println(error)
}
// 关闭响应体
response.Body.Close()
// 打印响应体
fmt.Println(string(body))
这是响应的内容：
/*
