PHP realizes QQ, WeChat and Alipay payment code consistency

When I was browsing blogs recently, I found that many blogs have a tipping function. Although there may be very few people who tip, it is always a thoughtful gesture that allows bloggers to know that the articles they write are useful and can help others. . Therefore, I also wanted to add a tipping function~

Analysis

But after browsing around github, I found that the tipping plug-ins are basically the same: QQ scan code/WeChat Scan the QR code/Alipay scan the QR code.

Some click each button to display each payment code

Some do not Each payment code is displayed in full

Scan this one with WeChat and scan that one with Alipay. Not only do you have to load multiple QR codes, but you also need to add css/js to make it look good. As a person who is lazy and doesn’t want to write these For programmers, this is not possible.

Can I combine QQ, WeChat and Alipay into one, and only need to scan a payment code?

This involves a knowledge point, which is User-Agent. The webviews of major manufacturers will carry their own UA information, for example:

QQ: MQQBrowser/6.2 TBS/043221 Safari/537.36 QQ/7.0.0.3135

WeChat: MQQBrowser/6.2 TBS 043220 Safari/537.36 MicroMessenger/6.5.8.1060 NetType/4G Language/zh_CN

Alipay: UCBrowser /11.5.0.939 UCBS/2.10.1.6 Mobile Safari/537.36 AliApp(AP/10.0.15.051805) AlipayClient/10.0.15.051805 Language/zh-Hans

This way it is easy to distinguish whether it is QQ, WeChat or Alipay scanning code Now:

User-Agent contains QQ/ is QQ

User-Agent contains MicroMessenger is WeChat

User-Agent contains AlipayClient is Alipay

Since each software can be distinguished, you can build a URL yourself, scan the URL through QR code generation, and determine the UA of the browser to distribute different payment codes

roughly The process is:

The client scans the code-> The server determines the client type based on the User-Agent-> Returns different processes respectively

Start tossing

First decode the payment codes generated by QQ, WeChat and Alipay. You can go here or here to decode online.

QQ：https://i.qianbao.qq.com/wallet/sqrcode.htm?m=tenpay&a=1&u=17878127&ac=E04BE442991E7FFED28B3B5C3E187148F063DC3C6DACAD2983C87B482FC9E7AD&n=Schrödinger cat&f=wallet

(https protocol, cannot wake up QQ)

Alipay: HTTPS://QR.ALIPAY.COM/FKX03549OW666ME7BXWF7A

(https protocol, can directly wake up Alipay APP)

WeChat: wxp://f2f09hjzo72AAYEITIBaolV-3cvGrDjE0q7k

(WeChat’s own payment protocol cannot wake up WeChat)

You can write the code directly below , determine the User-Agent. If it is Alipay, it will directly jump to the Alipay link. If it is QQ and WeChat, it will jump to the QQ and WeChat links.

However, since QQ and WeChat cannot directly wake up the APP, directly output a QR code of QQ and WeChat, and then press and hold to scan the code to complete the payment.

The code is as follows:

<?php
$ua = $_SERVER[&#39;HTTP_USER_AGENT&#39;];
if (strpos($ua, &#39;MicroMessenger&#39;)) {
 $type = &#39;wepay&#39;;

}
elseif (strpos($ua, 'AlipayClient')) {
