OneQRCode

微信、支付宝、QQ 三合一收款二维码,单文件版

特点

  • 纯前端实现,无需安装,无需数据库;
  • 免维护,无任何多余的配置,只需修改收款链接,即可永久使用。

使用方法

  1. 点击下载 本项目代码到本地;
  2. 打开 index.html,将里面的收款码链接修改成你自己的;
  3. index.html 上传至你的网站空间,即可开始使用!

注意事项

  • 请用专门的 HTML 编辑器(如 VS Code)编辑代码,切勿直接用记事本编辑,否则可能出现中文乱码!
  • 本作品禁止任何形式的倒卖,转载请注明出处。

原理

在 微信、支付宝、QQ 中扫描到一个网址二维码后,一般会通过内置的浏览器打开这个网址。通过判断内置浏览器的 UA,即可得出当前扫码的具体支付平台。

if(navigator.userAgent.match(/Alipay/i)) {
    // 支付宝
} else if(navigator.userAgent.match(/MicroMessenger\//i)) {
    // 微信
} else if(navigator.userAgent.match(/QQ\//i)) {
    // QQ
} else {
    // 其它
}

其中,支付宝可以通过直接跳转收款链接唤起付款功能,而 QQ、微信 则需展示出对应的收款码,由用户自行长按识别真正的收款二维码实现唤起付款。
