  php微信支付之APP支付方法

  本文实例讲述了微信开放平台移动应用集成微信支付功能。分享给大家供大家参考。具体分析如下,更多消息请关注应届毕业生网!  WechatAppPay文件代码如下:  ?  <?php  namespace commonservicesWechatPay;  class WechatAppPay extends WechatPayBase    //package参数  public $package = [];  //异步通知参数  public $notify = [];  //推送预支付订单参数  protected $config = [];  //存储access token和获取时间的文件  protected $file;  //access token  protected $accessToken;  //取access token的url  const ACCESS_TOKEN_URL = 'https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=%s&secret=%s';  //生成预支付订单提交地址  const POST_ORDER_URL = 'https://api.weixin.qq.com/pay/genprepay?access_token=%s';  public function __construct    $this->file = __DIR__ .
