Question

我已经完成了使用https://www.npmjs.com/package/twitter从指定帐户获取推文的请求，但是，我无法访问返回的JSON对象的"text"部分。

这是从请求返回的JSON的示例部分：

[ { created_at: 'Sat Apr 08 10:16:51 +0000 2017',
    id: 850653659025334300,

    favorite_count: 6,
    favorited: false,
    retweeted: false,
    possibly_sensitive: false,
    lang: 'en' } ]

我只想要console.log JSON的text:部分，我用**标记了。这是我的代码：

const Twitter = require('twitter');

const Twit = new Twitter({
    consumer_key: 'XXX',
    consumer_secret: 'XXX',
    access_token_key: 'XXX',
    access_token_secret: 'XXX'
});

Twit.get('statuses/user_timeline', { screen_name: 'BBCSport', count: 1 }, function(error, tweets, response) {
    if (error) {
        console.log(error)
    }
    console.log(tweets);
});

我已经尝试了console.log(tweets.text)，我认为它会起作用，但是我收到一个错误，说它是未定义的。

我自己设法解决了这个问题，我没有意识到推文是一个对象数组，因此无法使用.text表示法进行访问，因此以下解决了它（循环数组，并且访问每个元素上的.text元素。在请求中，Count是count: 1个数字。

for (var i = 0; i < count; i++) {
    console.log(tweets[i].text);
}

访问JSON twitter节点模块的特定部分
