将 Twitter API 流用于多个 Twitter 帐户？

Question

我正在做一个项目，其中树莓派上的音频文件由来自特定帐户的推文触发。

我正在使用 node.js 和 npm twit 包。使用两个不同的 Twitter 帐户时，我已经能够让它工作。但是，当我尝试使用多个帐户（15 岁以上）时，它不起作用。

我的工作代码是这样的：

var userID1 = 'XXXXXXX'; //userID of first account 
var userID2 = 'XXXXXXX'; //UserdIp of Second account

//Following code set up stream just for USERID1
var stream = T.stream('statuses/filter', { follow: ( userID1 ) });  
stream.on('tweet', function (tweet) {

// two variables to store tweet time  and actual tweet
var tweetTime = new Date().toLocaleString();
var printTweet = tweet.text;

if (tweet.user.id == userID1 ) {

    printTweet.toString()//converts printTweet to String
    console.log(printTweet) //prints tweet as variable
    console.log("Tweet has been received from UserID1 + tweetTime");
    audio();
  }
});


//Following code set up stream just for USERID2
var stream = T.stream('statuses/filter', { follow: (  userID2 ) });  
stream.on('tweet', function (tweet) {


// two variables to store tweet time  and actual tweet
var tweetTime2 = new Date().toLocaleString();
var printTweet2 = tweet.text;

    if(tweet.user.id == userID2 ) {

        printTweet2.toString()//converts printTweet to String
        console.log(printTweet2) //prints tweet as variable
        console.log("Tweet has been received from UserID2" + tweetTime2);
        audio();

    }

 });

正如我在添加多个帐户时提到的那样，它不起作用。 它不会抛出错误消息，而是会冻结（对推文没有反应）。我认为问题可能是我只需要一个var stream 或一个stream.on 的实例，所以我尝试了这个：

var userID1 = 'XXXXXXX'; //userID of first account 
var userID2 = 'XXXXXXX'; //UserdID of Second account
var userID3 = 'xxxxxxx'; //user ID pf third account 
//I then have userID of another 15 accounts. 


//Following code set up stream just for all user IDs 
var stream = T.stream('statuses/filter', { follow: ( userID1, userID2, ****15 more userID***** ) });  

//just one stream.on for all followed twitter accounts
stream.on('tweet', function (tweet) {



//conditional for userID1
if (tweet.user.id == userID1 ) {

    // two variables to store tweet time and actual tweet
    var tweetTime = new Date().toLocaleString();
    var printTweet = tweet.text;

    printTweet.toString()//converts printTweet to String
    console.log(printTweet) //prints tweet as variable
    console.log("Tweet has been received from UserID1 + tweetTime");
    audio();
  }


//conditional for userID2  
    if(tweet.user.id == userID2 ) {

        // two variables to store tweet time and actual tweet
        var tweetTime = new Date().toLocaleString();
        var printTweet = tweet.text;

        printTweet2.toString()//converts printTweet to String
        console.log(printTweet2) //prints tweet as variable
        console.log("Tweet has been received from UserID2" + tweetTime2);
        audio();

}

//same conditional above done 15 more times for other accounts  

 });

但它又一次冻结了。

任何建议都会很棒。

Answer 1

您声明follow 列表的方式存在问题。它应该是一个以逗号分隔的用户 ID 列表，而在您的代码中您只需使用 comma-operator。试着把它改成这样：

{ follow: [ userID1, userID2, ... , userID17 ].join(',') }

在您的第二个代码示例中（我认为这更好），因此生成的代码如下所示：

var stream = T.stream('statuses/filter', { follow: [ userID1, userID2, ... , userID17 ].join(',') });  

//just one stream.on for all followed twitter accounts
stream.on('tweet', function (tweet) {

//conditional for userID1
if (tweet.user.id == userID1 ) {

    // two variables to store tweet time and actual tweet
    var tweetTime = new Date().toLocaleString();
    var printTweet = tweet.text;

    printTweet.toString()//converts printTweet to String
    console.log(printTweet) //prints tweet as variable
    console.log("Tweet has been received from UserID1 + tweetTime");
    audio();
  }


//conditional for userID2  
    if(tweet.user.id == userID2 ) {

        // two variables to store tweet time and actual tweet
        var tweetTime = new Date().toLocaleString();
        var printTweet = tweet.text;

        printTweet2.toString()//converts printTweet to String
        console.log(printTweet2) //prints tweet as variable
        console.log("Tweet has been received from UserID2" + tweetTime2);
        audio();

}

//same conditional above done 15 more times for other accounts  

 });
