使用相机从网页中读取 qrcode. [英] Read qrcode from a web page with camera.

问题描述

我正在寻找在网页上读取二维码的解决方案.

Im looking for a solution to read a QRCode on a webpage.

假设我用 PHP 和一些库(zxing 或其他东西)生成了一个 QRCode 并将其打印在一张纸上，好吗?

Lets say I've generated with PHP and some library (zxing or something else) a QRCode and its printed on a piece of paper, ok?

我现在想做的是用平板电脑/智能手机通过网页读回它.我浏览到那个页面，它要求我用相机对准二维码，然后将扫描的内容发送回解码它的页面.

What i would like to do now, is to read it back with tablet/smartphone throught a web-page. I browse to that page, it asks me to aim the QRCode with the camera, and then the scanned content is sent back to the page that decodes it.

有什么东西可以在不需要使用 Android/iOS 应用的情况下处理这个问题?它也可以是另一种二维条码，而不仅仅是二维码.

There's something out there to handle this without the need to use an Android/iOS app? It could be another type of 2D barcode aswell, not exclusively a QRCode.

TY

推荐答案

我曾经使用过 Lazarsoft 的 jsqrcode

I have once worked with Lazarsoft's jsqrcode

它在浏览器中运行良好，我知道他做了一个演示，在带摄像头的手机上进行测试.

It worked fine in the browser, and I know he made a demo to test on a phone with camera.

这是他的存储库:https://github.com/LazarSoft/jsqrcode
