如何在 nodejs 上的 .env 中设置变量

Question

I have a script like this:

const item = [
  companyid : 23,
  summaryid : 2
];

const url = process.env.urlLink;

And I want to set the url in .env like this:

urlLink = "https://example.com/print/index/companyid=" + item.companyid + "&summaryid=" + item.summaryid

When I console.log(url) , I want to get this value:

https://example.com/print/index/companyid=23&summaryid=2

But I always get this value instead:

https://example.com/print/index/companyid=" + item.companyid + "&summaryid=" + item.summaryid

How can I get the variable item.companyid and item.summaryid ?

Answer 1

Not a very elegant solution but it works

on .env put

         companyid : 23
         summaryid : 2
         LINK = "https://example.com/print/index/companyid="

on your log put

         console.log(process.env.LINK + process.env.companyid + "&summaryid=" + process.env.summaryid)

Answer 2

Try This :

In .env file :

 companyid = 23
 summaryid = 2
 LINK = "https://example.com/print/index/companyid="

in js file:

 console.log(process.env.LINK + process.env.companyid + "&summaryid=" + process.env.summaryid)

output:

 https://example.com/print/index/companyid=23&summaryid=2

Just to keep the array that you have in your script, your .env file could look like this:

urlLink = "https://example.com/print/index/companyid="
PARAM = "&summaryid="

And then your script

console.log(process.env.urlLink + item.companyid + process.env.PARAM + item.summaryid)
