用PHP动态生成QR码

问题描述

我正在尝试在我的网站上生成QR码.他们要做的就是在其中包含一个URL，该URL将在我的网站上提供.最简单的方法是什么?

解决方案

除了，Google提供了 QR代码API . /p>

要使用this，基本上是:

https://chart.googleapis.com/chart?chs=300x300&cht=qr&chl=http%3A%2F%2Fwww.google.com%2F&choe=UTF-8

• 300x300是要生成的QR图像的大小，
• chl是您要更改为QR码的URL编码的字符串，并且
• choe是(可选)编码.

上面的链接提供了更多细节，但是要使用它，只需将图像的src指向操纵值，就像这样:

<img src="https://chart.googleapis.com/chart?chs=300x300&cht=qr&chl=http%3A%2F%2Fwww.google.com%2F&choe=UTF-8" title="Link to Google.com" />

演示:

I'm trying to generate QR codes on my website. All they have to do is have a URL in them, which a variable on my site will provide. What would be the easiest way to do this?

解决方案

It's worth adding that, in addition to the QR codes library posted by @abaumg, Google provides a QR Codes API.

To use this , basically:

https://chart.googleapis.com/chart?chs=300x300&cht=qr&chl=http%3A%2F%2Fwww.google.com%2F&choe=UTF-8

• 300x300 is the size of the QR image you want to generate,
• the chl is the url-encoded string you want to change into a QR code, and
• the choe is the (optional) encoding.

The link, above, gives more detail, but to use it just have the src of an image point to the manipulated value, like so:

<img src="https://chart.googleapis.com/chart?chs=300x300&cht=qr&chl=http%3A%2F%2Fwww.google.com%2F&choe=UTF-8" title="Link to Google.com" />
