javascript - Front-end recognition and parsing of QR codes

Question

I need to do a picture scanning business, which is to scan the QR code. The QR code parsed out is a series of serial numbers. Now I want to know if there is a corresponding third-party plug-in on the front end that can complete the decoding of the QR code. Or are there any other good ideas

Answer 1

Front-end solution: qrcode.js

The correct and safe solution should be to generate a QR code from the backend and then send you the URL of the QR code image.
