javascript - Is there a javascript/Node.js library for accessing the Alchemy Data News API?

Question

I've looked in the watson-developer-cloud package and its namesake namespace on GitHub. Will I need to go directly to the REST API in my app?

Answer 1

watson-developer-cloud您可以使用npm 模块访问所有 Watson 和 Alchemy API 。

1. 安装 npm 模块。

   $ npm install watson-developer-cloud
   

2. 从Bluemix获取 Alchemy API 密钥。

3. 创建一个test.js包含以下内容的文件

   var watson = require('watson-developer-cloud');
   
   var alchemy_data_news = watson.alchemy_data_news({
     api_key: '<api_key>'
   });
   
   var params = {
     start: 'now-1d',
     end: 'now'
   };
   
   alchemy_data_news.getNews(params, function (err, news) {
     if (err)
       console.log('error:', err);
     else
       console.log(JSON.stringify(news, null, 2));
   });
