使用base64函数会导致InvalidCharacterError

Question

What I want to do is using base-64 module method, in my node.js + express project.

The code is like this.

router.get('/list', function(req, res, next) {
    client.query('SELECT * FROM Document',function(err, row){
        if(err) throw err;
        var base64 = require('base-64');
        row.forEach(e => {
            e.text = base64.decode(e.text);
        });
        res.render('main/list',{title:"###", row:row});
    })
});

In this function, there are MySQL query in the callback.

The text is the base-64 encoded value of the Database.

But, the base64.encode() doesn't work in this code, but results in InvalidCharacterError

how should I use correctly?

You can use nodejs built-in functions

let original = 'abcdefrgsdfdsf123123123123';
let testCode64 = Buffer.from(original).toString('base64') 
let testDecode64 = Buffer.from(testCode64, 'base64').toString('utf-8');
