json - 如何使用 json.stringify 获取推文的某些参数并将其保存到文件中？ (我使用的方法适用于 Stream，但不适用于 GET)

Question

我试图仅将用户@screen_name 和使用 Twitter API 获得的推文文本保存到文件中，但在 Twitter API 网站或 json.strinigify 文档上找不到任何相关文档。我正在使用的代码由于某种原因实际上不能与 GET 一起使用，它是这样的(我在 Google 中找不到与解决我的问题相关的任何内容):

var params = {q: '@Avengers, count: 1, include_rts: 1};
client.get('search/tweets', params, function(error, tweets, response) {
if (!error) {
    console.log(tweets);
    fs.appendFile("tweet.txt", JSON.stringify(tweets.text), function (err) {
    //user.name or .text doesn't work in GET and I am trying to find the methods
    //that work for GET 
        if (err) throw err;
            console.log('Saved!');
        }); 
    }
});

当我使用 Stream 来使用类似的东西时，它确实有效，并且保存了发布推文的用户名和推文的文本(这是我需要的)。我的问题是，流没有任何方法来获取用户@screen_name 的推文，所以我继续使用 GET 方法。我执行此操作的流代码如下:

var stream = client.stream('statuses/filter', {track: 'Avengers'});
    stream.on('data', function(event) {
        console.log("Tweeted by ::::>>>" + event.user.name + " ::::>>> " +  "Tweet is :::>>>> " + event.text + " ::::>>>");
        fs.appendFile("tweet.txt", JSON.stringify(event.user.name+' ////////'+event.text)+"\n", function (err) {
        if (err) throw err;
        console.log('Saved!');
    });
});

我使用 GET 方法得到的结果是一大堆参数，当它保存在文件中时我不需要:

我的 Stream 方法正确执行此操作，但我的 GET 没有，这就是我的流给我的:

"Trash Flaten ////////@lliejuve @lliejuve on current tv it has to be the voice actor for Thor in Disney's Avengers Assemble. So o respect…

如您所见，Stream 为我提供了我需要的用户 @screen_name 和推文文本，但在 GET 方法中 user.name 和 .text 并没有这样做。

Answer 1

var params = {q: '@Avengers, count: 1, include_rts: 1};
client.get('search/tweets', params, function(error, tweets, response) {
if (!error) {
    console.log(tweets);
    fs.appendFile("tweet.txt", JSON.stringify(tweets.statuses[0].text), function (err) {
        if (err) throw err;
            console.log('Saved!');
        }); 
    }
});

尝试上面的更改。它应该可以工作。
