在.env中获取Facebook Messenger Page_Access_Token

Question

According to Facebook Guide line, I was told to create a .env file to store the Page_Access_Token The content in .env is:

PAGE_ACCESS_TOKEN="XXXXXXXXXXXXXXXXX"

and we have an app.js that included:

const PAGE_ACCESS_TOKEN = process.env.PAGE_ACCESS_TOKEN;

However, when I console.log(process.env.PAGE_ACCESS_TOKEN); it returns me an undefined

Can advise how to fix this problem?

PS I am using windows and ngrok to test

Answer 1

.env without any configurations or tools does nothing, unless your told your app to, this is just a basic file.

However if you really want to use a .env to store your environment variables, you may need something like this dotenv
