如何在Node中解析HTTP状态代码？

Question

I'm using an API library in Node that doesn't return the status code of the HTTP response. However, it does return the response headers, which look like this:

{ ...
  status: '200 OK',
  ... }

Is there any Node library I can use to parse the status code from the returned object's status? Will a crude +res.status.slice(0, 3) do?

EDIT: Link to the library.

Answer 1

All HTTP status codes have 3 digits, so your slice example will work. However, I would personally just split on space:

var code = status.split(' ')[0];
