How to implement the three-in-one payment code of QQ, WeChat and Alipay using PHP

This time I will show you how to use PHP to implement the three-in-one payment code of QQ, WeChat and Alipay. What are the precautions , the following is a practical case, let’s take a look.

Preface

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

Analysis

But after browsing around github, I found that the tipping plug-in is basically They are all the same: QQ code scanning/WeChat code scanning/Alipay code scanning.

Some click each button to display each payment code

Sometimes, each payment code appears Show them all

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

Can I combine QQ, WeChat and Alipay into one, just by scanning a payment code?

There is a knowledge point involved here, 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 is very easy Distinguish whether it is QQ, WeChat or Alipay scan code:

User-Agent contains QQ/ is QQ

User-Agent contains MicroMessenger is WeChat

User-Agent contains AlipayClient is Alipay

Since it can distinguish each software, it can create a self-built URL, scan the URL through QR code generation, and determine the UA of the browser to distribute different payment codes

The rough process is:

The client scans the code-> The server determines the client type based on the User-Agent-> Returns different processing 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=Xue Dinger's 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 to determine if the User-Agent is Alipay Directly jump to the Alipay link. If it is QQ and WeChat, jump to the QQ and WeChat link.

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;;
 $name = &#39;微信支付&#39;;
 //微信支付链接
 $url = &#39;wxp://f2f09hjzo72AAYEITIBaolV-3cvGrDjE0q7k&#39;;
 $icon_img = &#39;<img src="http://ww2.sinaimg.cn/large/005zWjpngy1fojrwgr20oj303k03kglg.jpg" width="48px" height="48px" alt="&#39;.$name.&#39;">';
}
elseif (strpos($ua, 'AlipayClient')) {
 //支付宝链接
 $url = 'HTTPS://QR.ALIPAY.COM/FKX03479QJ0RVOS3UJLQAE';
 header('location: ' . $url);
}
elseif (strpos($ua, 'QQ/')) {
 $type = 'qq';
 $name = 'QQ钱包支付';
 //QQ钱包支付链接
 $url = 'https://i.qianbao.qq.com/wallet/sqrcode.htm?m=tenpay&a=1&u=17878127&ac=E04BE442991E7FFED28B3B5C3E187148F063DC3C6DACAD2983C87B482FC9E7AD&n=薛定谔的猫&f=wallet';

}
else {
 $type = 'other';
 $name = '打赏作者';
 $url = 'http://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
 $icon_img = '<img src="http://ww2.sinaimg.cn/large/005zWjpngy1fojs089x6tj303k03kjr6.jpg" width="48px" height="48px" alt="&#39;.$name.&#39;">';
}
$qr_img = '<img src="http://qr.liantu.com/api.php?text=&#39;.urlencode($url).&#39;">';
