The development of ThinkPHP5 WeChat cash red envelopes

This article mainly introduced about the ThinkPHP5 cash red envelope development, has certain reference value, now shares to everybody, has the need friend can refer to

———— above, because my code is written under Common.php, and common.php is in the application directory, so the certificate is placed under the application/cert/wxpay/directory
