It could be better to use a module like request(alternatives), but you could do it like this:
使用像request（替代品）这样的模块可能会更好，但你可以这样做：
ES6 version
ES6版本
http.get('some_mp3_url', res => res.pipe(fs.createWriteStream('some.mp3')));
ES5 version
ES5版本
http.get('some_mp3_url', function (res) {
res.pipe(fs.createWriteStream('some.mp3'));
});
Note: besides fs, the http(or https) module also has to be imported/required.
注意：除此之外fs，还必须导入/需要http(or https) 模块。
