微信扫码支付（laravel）

1.未开通微信扫码支付

(1).参照微信扫码支付接入步骤

(2).开通成功之后用分配的商户号登录微信商户平台设置扫码支付的异步回调地址（注意：是返给商户后台的回调地址）

2.已经开通扫码支付

模式二：

业务流程：参照微信支付文档模式二

phpqrcode.php 文件在下载的微信支付demo里面就有

贴上二维码图片文件生成代码：

<?php
namespace App\StarShow;
require_once 'Phpqrcode/phpqrcode.php';/****/
class Qrcode {public function generate($text) {error_reporting(E_ERROR);$url = urldecode($text);$PNG_TEMP_DIR = getcwd() . '/temp/';if (!file_exists($PNG_TEMP_DIR)) {mkdir($PNG_TEMP_DIR);}$filename = 'test' . md5($url . '|L|4') . '.png';\QRcode::png($url, $PNG_TEMP_DIR . $filename, 'L', 4, 2);return '/temp/' . $filename;}
}

本人遇到的问题是选择微信支付之后直接生成了二维码，扫码之后没有任何反应；故改变二维码的生成策略；选择支付方式为微信支付之后，点击去支付，此时后台生成一个二维码图片＋订单号＋订单失效时间＋服务器当前时间一起返给前端，这个时候前端做的处理是遮罩层弹出二维码，从弹出二维码那一刻前端根据订单失效时间－服务器当前时间＝时间差 用这个时间差做一个2-3s定时请求后台的处理，根据订单号来定时请求后台查看支付结果，在失效时间结束之前如果支付成功则做各自的业务处理，如果失败则继续请求直到失效时间结束，如果用户关闭页面则不在验证。
