tp5支付宝和微信支付

一、生成二维码给用户进行扫码支付

1、先在vendor目录下加入支付宝和微信支付的引用

2、付款处调用

/**
     * 订单支付接口
     *
     * @api {post} {:url('order/pay')} 前台订单支付二维码接口
     * @apiName pay
     * @apiGroup Order
     * @apiParam {String} type 支付类型 alipay,wxpay
     * @apiParam {String} sn 订单号
     * @apiSuccess (200) {String} /uploads/tmp/testbfb0f121f0114a8238a8888ed116af50.png 支付二维码地址
