一个jsonObject里面放了一个jsonArray 且这个jsonArray中 每个json对象是一个jsonArray
注：下面就是一个json对像
"ZRX": [
0.8702223997999999,
0.8775768147,

1.0422256544,
1.0024517779,
1.0017013274
]
我们的目标是取出每个json对象的Key值，即这里的"ZRX"；并且，取出每个jsonArray中的第一个数字参数；
实现如下：
needle.get('https://api.lionshare.capital/api/prices', function(error, response) {
//get方法获取json数据
if (!error && response.statusCode == 200)
//第一步，读取出"data":[]数组数据
var dataJson=response.body.data;
var coinNames=[];
var coinPrice0=[];
var coinPrice4=[];
//第二部， for 循环读取每个json对象中的Key（jsonArray的名称）
for (let djson in dataJson) {
//dataJson.get(i);
coinNames.push(djson);
//第三步，[][]获取每个jsonArray中固定位置的数值
coinPrice0.push(dataJson[djson][0]);
coinPrice4.push(dataJson[djson][4]);
console.log(dataJson[djson][0]);
}
//ejs传参
res.render('account/market', {info:coinNames,coinPrice0:coinPrice0,coinPrice4:coinPrice4});
});
然后，完成。
