实现思路
- 生成一个二维码，加入要处理的url连接
- 在用户扫完码后，在对应的脚本中，判断扫码终端，调用相应的支付
- 若能够扫码之后能唤起相应app，支付宝要用手机网站支付方式，微信要使用jsapi支付方式
效果展示
提示： 因为项目即将上线，所以上面的支付二维码连接被我替换了(注意在生成二维码时加入的连接，要带上http协议)
实现
步骤生成二维码
//我的url指向了checkTerrace方法 $url = self::ADMIN_URL . 'params=' . $params; //ADMIN_URL是生成二维码的url，请替换成自己
处理用户扫码操作(checkTerrace方法)
public function checkTerrace()
{
$pay_type = $this->getPayType(); //该方法使用来判断用户扫码终端的
$params = $this->request->get('params'); //生成二维码url带的参数(看个人需求，我的项目需要额外参数)
$params = $this->desDecode($params); //这里是因为我对参数进行了desc加密，看个人需求
if ($pay_type === 'alipay') { //如果用户是通过支付宝扫码，进行支付宝相关操作
if ($params === false) {
echo "系统错误!，请稍后重试";
exit;
}
$res = $this->createOrder($pay_type, $params);
if (!$res) {
echo "系统错误，请稍后重试";
exit;
}
$this->aliPay($res);
} elseif ($pay_type === 'wechat') { //如果用户是通过微信扫码，进行微信相关操作
if ($params === false) {
echo "系统错误，请稍后重试";
exit;
}
$prepare = $this->wechat($pay_type, $params);
$this->assign('json', $prepare);
return $this->display('wpay.html');
} elseif ($pay_type === false) {
echo "请使用支付宝或微信进行扫码";
exit;
}
}
判断扫码终端
/**
* 判断扫码终端
*
* @return string|boolean
* @date 2021-02-04
*/
private function getPayType()
{
if (strstr($_SERVER['HTTP_USER_AGENT'], 'AlipayClient')) {
return "alipay";
} elseif (strstr($_SERVER['HTTP_USER_AGENT'], 'MicroMessenger')) {
return "wechat";
} else {
return false;
}
}
生成订单
/**
* 生成订单
*
* @param string $pay_type
* @param json $params
* @return void
* @date 2021-02-04
*/
//这个逻辑就不贴代码了
private function createOrder($pay_type, $params)
{
/*生成订单相关逻辑代码*/
}
支付宝支付
/**
* 唤起支付宝app
*
* @param array $api_params
* @return void
* @date 2021-02-04
*/
private function aliPay($api_params)
{
$config = [
'notify_url' => '异步回调地址',
'is_open_certificate' => true
];
$domain = urlencode($api_params['domain']);
$api = [

'total_amount' => '0.01',
'subject' => '商品标题',
'passback_params' => $domain
];
$pay = new Pay($config);
$res = $pay->driver('alipay')->gateway('wap')->pay($api); //调用支付宝手机网站支付
echo $res;
}
微信支付
/**
* 唤起微信app
*
* @return void
* @date 2021-02-04
*/
public function wechat($pay_type, $params)
{
$opend_id = $this->getOpenId(); //处理微信jsapi支付之前，要先获取用户的openID
if (!$opend_id) {
echo "微信授权失败...";
exit;
}
$api_params = $this->createOrder($pay_type, $params); //用户openID获取成功后才进行订单生产操作
if (!$api_params) {
echo "系统错误，请稍后重试";
exit;
}
$config = ['notify_url' => '微信异步回调地址'];
$api = [
'body' => '我是标题',
'out_trade_no' => $api_params['trade_no'],
'total_fee' => 1,
'openid' => $opend_id,
'attach' => $api_params['domain']
];
$pay = new Pay($config);
$res = $pay->driver('wechat')->gateway('mp')->pay($api); //调用微信jsapi支付
return $res;
}
静默获取openID
/**
* 获取用户的openid
*
* @return void
* @date 2021-02-04
*/
public function getOpenId()
{
if (isset($_SESSION['open_id']) && $_SESSION['open_id']) {
return $_SESSION['open_id'];
}
if (!$this->request->get('code')) {
$redirect_uri = $_SERVER['REQUEST_SCHEME'] . '://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI']; //这里授权后微信跳转的地址，要写在订单处理处，否则会造成因为程序跳转到微信授权页面，导致脚本逻辑终止
$redirect_uri = urlencode($redirect_uri);
$url = $this->codeUrl . 'redirect_uri=' . $redirect_uri . '&appid=' . $this->appId . '&scope=snsapi_base&response_type=code&state=STATE#wechat_redirect'; //使用用户静默授权模式(因为我不需要获取用户信息所有就没采用用户手段授权模式)
header("location:{$url}"); //跳转到微信授权页面
} else {
$openidurl = $this->openidUrl . 'appid=' . $this->appId . '&secret=' . $this->appSecret . '&code=' . $this->request->get('code') . '&grant_type=authorization_code';
$data = Http::get($openidurl);
$data = json_decode($data, true);
if ($data['openid']) {
$_SESSION['open_id'] = $data['openid']; //获取到的用户openID存储到session中
} else {
$_SESSION['open_id'] = false;
}
return $_SESSION['open_id'];
}
}

前端效果：
用户进入支付页面但是一直为扫码，超过一定时间
用户扫码后一直未进行支付，超过一定时间
