THINKPHP 安装Yansongda 微信支付宝支付

1、在vendor 目录使用composer安装，命令： composer require yansongda/pay -vvv

2、在控制器中引用 Yansongda\Pay\Pay

微信支付：

public function done(){
    $config = [
        'appid' => 'wxb3fxxxxxxxxxxx', // APP APPID
        'app_id' => 'appid', // 公众号 APPID
        'miniapp_id' => 'wxb3fxxxxxxxxxxx', // 小程序 APPID
        'mch_id' => 'merchant', // 商户ID
        'key' => 'secretkey',
        'notify_url' => url('user/public/wechatNotify',[],true,true),
        'cert_client' => './cert/apiclient_cert.pem', // optional, 退款，红包等情况时需要用到
        'cert_key' => './cert/apiclient_key.pem',// optional, 退款，红包等情况时需要用到
        'log' => [ // optional
             'file' => LOG_PATH.'logs/wechat.log',
             'level' => 'info', // 建议生产环境等级调整为 info，开发环境为 debug
             'type' => 'single', // optional, 可选 daily.
             'max_file' => 30, // optional, 当 type 为 daily 时有效，默认 30 天
        ],
        'http' => [ // optional
            'timeout' => 5.0,
            'connect_timeout' => 5.0,
        ],
         // 'mode' => 'dev',
   ];
   // 使用方法
   $wechat = Pay::wechat($config);
   $order = [
      'out_trade_no' => $number,
      'body' => '支付',
      'total_fee'      => intval($order['money'] * 100),
   ];
   $result = $wechat->scan($order);
   // 二维码内容：
   $qr = $result->code_url;
   $url2   = base64_encode($qr);
   $this->assign('text', $url2);
   return $this->fetch();
}
