从响应中获取数组中的元素-解网

问：

我想从HTTP响应的数组中获取第二个元素，但我不明白如何。

        // make GET request
        response, error := http.Get("https://api.binance.com/api/v3/klines?symbol=ETHUSDT&interval=5m&limit=5")
        if error != nil {
            fmt.Println(error)
        }
    
        // read response body
        body, error := ioutil.ReadAll(response.Body)
    
        if error != nil {
            fmt.Println(error)
        }
    
        // close response body
        response.Body.Close()
    
        // print response body
        fmt.Println(string(body))

这是责任：

我想从第二个数组中获取第二个项目。请帮我解析数组并获取我需要的元素

数组 API Go 解析

示例项目试用这个。JsonResp 结构，表示 JSON 响应的结构。然后，它发出 HTTP 请求，读取并解析响应正文，并从中提取第二个元素。resp

查看示例项目以更好地理解

上一个：Java 中的解析不适用于 JSONArray

下一个：Php 将文本解析为包含重复键的数组

从响应中获取数组中的元素

get element from array from response
