NodeJS dotenv - 没有正确读取字符串值

Question

I'm trying to us dotenv ( https://github.com/motdotla/dotenv ) in nodeJS to store the client secret value for an oauth server I'm using.

My .env file looks like the following:

clientSecret=imU86A3oPiZlyOhZybShraP377ers0MvowBaizEQ

Within the NodeJS file, I have the following:

passport.use(new PasswordGrantStrategy({
    tokenURL: 'WEBSITE_ADDRESS',
    clientID: "2",
    clientSecret: process.env.clientSecret,
    grantType: "password",

},

The problem is that I get a Token Error but, if I change it the following:

passport.use(new PasswordGrantStrategy({
    tokenURL: 'WEBSITE_ADDRESS',
    clientID: "2",
    clientSecret: "imU86A3oPiZlyOhZybShraP377ers0MvowBaizEQ",
    grantType: "password",

},

This then works perfectly fine. I don't understand what the problem could be and I've tried to cast it as a string but no such luck.

The values are both matching and I'm printing them out and they are both the same.

使用反引号包裹字符串值，您的生活将变得轻而易举！

clientSecret=`imU86A3oPiZlyOhZybShraP377ers0MvowBaizEQ`

Answer 2

Make sure you have dotenv installed Make sure you config dotenv as early as possible in your app

require('dotenv').config({path: __dirname + '/.env'});

note: good idea to use the path parameter in some setups, for example if using a debugger otherwise dotenv may not find and load the .env file.

If you need to set dynamically the environment value in you app variable

 for(const [keyObj, valObj] of Object.entries(data)){
     for(const [key, value] of Object.entries(valObj)){
         app.set(key.toLocaleLowerCase(), value);
     }
 }
