我一直在看以下示例: https://github.com/pilwon/node-google-finance/blob/master/examples/callback/historical-multiple.js
但是我不断得到: 未定义,不适用
我想知道自己在做什么错,这是我正在使用的代码
var util = require('util');
//require('colors');
var googleFinance = require('google-finance');
var SYMBOL = 'NASDAQ:AAPL';
var FROM = '2014-01-01';
var TO = '2014-12-31';
googleFinance.historical({
symbol: SYMBOL,
from: FROM,
to: TO
}, function (err, quotes) {
if (err) { throw err; }
console.log(util.format(
'=== %s (%d) ===',
SYMBOL,
quotes.length
).cyan);
if (quotes[0]) {
console.log(
'%s\n...\n%s',
JSON.stringify(quotes[0], null, 2),
JSON.stringify(quotes[quotes.length - 1], null, 2)
);
} else {
console.log('N/A');
}
});
