PHP實現一個二維碼同時支持支付寶和微信支付

實現思路

  • 生成一個二維碼,加入要處理的url鏈接
  • 在用戶掃完碼後,在對應的腳本中,判斷掃碼終端,調用相應的支付
  • 若可以掃碼以後能喚起相應app,支付寶要用手機網站支付方式微信要使用jsapi支付方式

效果展現


提示: 由於項目即將上線,因此上面的支付二維碼鏈接被我替換了(注意在生成二維碼時加入的鏈接,要帶上http協議)javascript

實現步驟

生成二維碼

//個人url指向了checkTerrace方法
$url    = self::ADMIN_URL . 'params=' . $params; 
//ADMIN_URL是生成二維碼的url,請替換成本身

處理用戶掃碼操做(checkTerrace方法)

public function checkTerrace()
    {
      $pay_type = $this->getPayType(); //該方法使用來判斷用戶掃碼終端的
      $params   = $this->request->get('params'); //生成二維碼url帶的參數(看我的需求,個人項目須要額外參數)
      $params   = $this->desDecode($params); //這裏是由於我對參數進行了desc加密,看我的需求
      if ($pay_type === 'alipay') { //若是用戶是經過支付寶掃碼,進行支付寶相關操做
              if ($params === false) {
                  echo "系統錯誤!,請稍後重試";
                  exit;
              }
              $res = $this->createOrder($pay_type, $params);
              if (!$res) {
                  echo "系統錯誤,請稍後重試";
                  exit;
              }
              $this->aliPay($res);
      } elseif ($pay_type === 'wechat') { //若是用戶是經過微信掃碼,進行微信相關操做
              if ($params === false) {
                  echo "系統錯誤,請稍後重試";
                  exit;
              }
              $prepare = $this->wechat($pay_type, $params);
              $this->assign('json', $prepare);
              return $this->display('wpay.html');
      } elseif ($pay_type === false) {
              echo "請使用支付寶或微信進行掃碼";
              exit;
      }
  }

用戶進入支付頁面可是一直爲掃碼,超過必定時間

用戶掃碼後一直未進行支付,超過必定時間
