TFL Twitter情感分析

一个节点模块分析了最新的Twitter提要，其中提到了每个伦敦地下线，并且使用HP Idol Ondemand情感分析来确定每一条线都会收到正面或新的推文。

##用法### inatall

 npm install git://github.com/Lissy93/london-underground-live-sentiment-analysis.git

包括

 var tflSentimentAnalysis = require('tfl-sentiment-analysis');

认证

您将需要在https://api-portal.tfl.gov.uk/signup上注册API键，以及http://www.idolondemand.com/signup.html的HP OnDemand键，是免费的。创建与此类似的JSON：

 exports.HP_API_KEY = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';

exports.TWITTER_API = {
    CONSUMER_KEY        : "xxxxxxxxxxxxxxxxxxxxxxxxx",
    CONSUMER_SECRET     : "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
    ACCESS_TOKEN_KEY    : "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
    ACCESS_TOKEN_SECRET : "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
};

您应该将其与其他API键一起将其放入单独的文件中，然后将文件添加到.gitignore

提出简单的请求

 tflSentimentAnalysis . fetchTflSentiments ( keys , function ( results ) {
    console . log ( results ) ; // Do whatever with the results
} ) ;
