php微信jsapi支付 支付宝支付 两码合一
产品开会提出了这样的需求：一个二维码可以微信支付也可以支付宝支付
经过自己的钻研以及询问技术高人（本人代码一般般）和网上搜索 最终实现其功能 我用微信jsapi 和 支付宝网页支付
其实并不怎么难：
1.微信jsapi支付流程（微信官方文档：https://pay.weixin.qq.com/wiki/doc/api/jsapi.php?chapter=11_1）
2.支付宝支付流程
好了废话不多说 开始开发 代码上(Tp5开发)
首先 需要生成一个二维码这个想必大家都会吧！！！ phpqrcode(下载地址：https://sourceforge.net/projects/phpqrcode/ )
1 require_once ROOT_PATH.'/phpqrcode/phpqrcode.php';
2 $value='http://'.$_SERVER['HTTP_HOST'].'/admin.php/pay/wx_zfb; //二维码链接 （这个是重中之重！！！）
3 $errorCorrectionLevel = 'H';//容错级别
4 $matrixPointSize = 6;//生成图片大小
5 //生成二维码图片
6 QRcode::png($value, 'code/1.png', $errorCorrectionLevel, $matrixPointSize, 2);
7 $logo = 'code/kunchuan.png';//准备好的logo图片
8 $QR = 'code/1.png';//已经生成的原始二维码图
9 if ($logo !== FALSE) {
10 $QR = imagecreatefromstring(file_get_contents($QR));
11 $logo = imagecreatefromstring(file_get_contents($logo));
12 /* $QR = imagecreatefrompng($QR);
13 $logo = imagecreatefrompng($logo);*/
14 if (imageistruecolor($logo))
15 {
16 imagetruecolortopalette($logo, false, 65535);//添加这行代码来解决颜色失真问题
17 }
18
19 $QR_width = imagesx($QR);//二维码图片宽度
20 $QR_height = imagesy($QR);//二维码图片高度
21 $logo_width = imagesx($logo);//logo图片宽度
22 $logo_height = imagesy($logo);//logo图片高度
23 $logo_qr_width = $QR_width / 5;
24 $scale = $logo_width/$logo_qr_width;
25 $logo_qr_height = $logo_height/$scale;
26 $from_width = ($QR_width - $logo_qr_width) / 2;
27 //重新组合图片并调整大小
28 imagecopyresampled($QR, $logo, $from_width, $from_width, 0, 0, $logo_qr_width,
29 $logo_qr_height, $logo_width, $logo_height);
30 }
31
32 $lujing = 'code/merge1'.png';
33
34 //输出图片
35 imagepng($QR,$lujing);
36 return '';
ok我们就生成一个二维码 因为个人隐私 我就生成了一个百度的二维码
通过扫描二维码 我们跳转到 wx_zfb方法：
public function wx_zfb()
{
//根据自己的需求 链接上边有参数就接值 没有就不做判断
// if($this->request->isGet())
// {
//在PHP中HTTP_USER_AGENT是用来获取用户的相关信息的，包括用户使用的浏览器，操作系统等信息，
$http_user_agent = $_SERVER['HTTP_USER_AGENT'];
if (strpos($http_user_agent, 'MicroMessenger'))
{
$url="code”;//处理微信支付的方法
header("location:{$url}");
exit;
}elseif (strpos($http_user_agent, 'AlipayClient')) {
//支付宝链接
$url="aliyun”;//处理微信支付的方法
header("location:{$url}"); exit
}else{
$this->assign('error_data','请使用微信或者支付宝扫码哦！');
return $this->view->fetch('pay/error');
}
// }else{
// $this->assign('error\_data','暂时没有哦');
// return $this->view->fetch('pay/error');
//}
}接下来精彩的代码即将上线（微信jsapi支付）
