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 = $_SERVER['HTTP_USER_AGENT']; if (strpos($ua, 'MicroMessenger')) { $type = 'wepay'; $name = '微信支付'; //微信支付链接 $url = 'wxp://f2f09hjzo72AAYEITIBaolV-3cvGrDjE0q7k'; $icon_img = '<img src="/static/imghwm/default1.png" data-src="http://ww2.sinaimg.cn/large/005zWjpngy1fojrwgr20oj303k03kglg.jpg" class="lazy" style="max-width:90%" height="48px" alt="'.$name.'">'; } 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'; $icon_img = '<img src="/static/imghwm/default1.png" data-src="http://ww2.sinaimg.cn/large/005zWjpngy1fojrvmp427j303k03kjrb.jpg" class="lazy" alt="How to implement the three-in-one payment code of QQ, WeChat and Alipay using PHP" >'; } else { $type = 'other'; $name = '打赏作者'; $url = 'http://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']; $icon_img = '<img src="/static/imghwm/default1.png" data-src="http://ww2.sinaimg.cn/large/005zWjpngy1fojs089x6tj303k03kjr6.jpg" class="lazy" alt="How to implement the three-in-one payment code of QQ, WeChat and Alipay using PHP" >'; } $qr_img = '<img src="/static/imghwm/default1.png" data-src="http://qr.liantu.com/api.php?text='.urlencode($url).'" class="lazy" alt="How to implement the three-in-one payment code of QQ, WeChat and Alipay using PHP" >'; ?> nbsp;html> <meta> <meta> <meta> <meta> <title>=$name?></title> <style> * {margin: auto;padding: 0;border: 0;} html {-ms-text-size-adjust: 100%;-webkit-text-size-adjust: 100%} body {font-family: -apple-system, SF UI Text, Arial, Microsoft YaHei, Hiragino Sans GB, WenQuanYi Micro Hei, sans-serif;color: #333;} img {max-width: 100%;} h3 {padding: 10px;} .container {text-align: center;} .title {padding: 2em 0;background-color: #fff;} .content {padding: 2em 1em;color: #fff;} .wepay {background-color: #23ac38;} .qq {background-color: #4c97d5;} .other {background-color: #ff7055;} </style> "> <p> </p><p>=$icon_img?></p><h1 id="name-gt">=$name?></h1> <p>=$type=='other'?$qr_img.'</p><h3 id="请使用支付宝-微信-QQ客户端扫码付款">请使用支付宝、微信、QQ客户端扫码付款</h3>':$qr_img.'<h3 id="扫描或长按识别二维码-向TA付款">扫描或长按识别二维码,向TA付款</h3>'?>

php把负数转为正整数的方法:1、使用abs()函数将负数转为正数,使用intval()函数对正数取整,转为正整数,语法“intval(abs($number))”;2、利用“~”位运算符将负数取反加一,语法“~$number + 1”。

实现方法:1、使用“sleep(延迟秒数)”语句,可延迟执行函数若干秒;2、使用“time_nanosleep(延迟秒数,延迟纳秒数)”语句,可延迟执行函数若干秒和纳秒;3、使用“time_sleep_until(time()+7)”语句。

php字符串有下标。在PHP中,下标不仅可以应用于数组和对象,还可应用于字符串,利用字符串的下标和中括号“[]”可以访问指定索引位置的字符,并对该字符进行读写,语法“字符串名[下标值]”;字符串的下标值(索引值)只能是整数类型,起始值为0。

php除以100保留两位小数的方法:1、利用“/”运算符进行除法运算,语法“数值 / 100”;2、使用“number_format(除法结果, 2)”或“sprintf("%.2f",除法结果)”语句进行四舍五入的处理值,并保留两位小数。

判断方法:1、使用“strtotime("年-月-日")”语句将给定的年月日转换为时间戳格式;2、用“date("z",时间戳)+1”语句计算指定时间戳是一年的第几天。date()返回的天数是从0开始计算的,因此真实天数需要在此基础上加1。

在php中,可以使用substr()函数来读取字符串后几个字符,只需要将该函数的第二个参数设置为负值,第三个参数省略即可;语法为“substr(字符串,-n)”,表示读取从字符串结尾处向前数第n个字符开始,直到字符串结尾的全部字符。

方法:1、用“str_replace(" ","其他字符",$str)”语句,可将nbsp符替换为其他字符;2、用“preg_replace("/(\s|\ \;||\xc2\xa0)/","其他字符",$str)”语句。

查找方法:1、用strpos(),语法“strpos("字符串值","查找子串")+1”;2、用stripos(),语法“strpos("字符串值","查找子串")+1”。因为字符串是从0开始计数的,因此两个函数获取的位置需要进行加1处理。
