微信扫码支付 回调 跳转 带前端 响应代码
微信扫码登录不同的就是 支付成功 只有异步没有，支付成功的跳转。因此我们在支付扫码的时候要一直检测是否支付成功。
微信扫码支付的代码 配置
这几个代码去官方下载就好
微信配置账号在
别的不用动。下面我们开始请求

act 请求地址是 返回微信的 二维码 就是生成二维码
后台 act 代码

异步回调验证

check.php
检测是否支付成功！
传到前面的是订单号。
拿订单号去 后台验证
<?php $order_id = $_GET['order_id']; $order = C::t('a')->fetch_by_order_id($order_id); $succeed = 0; if($order && $order['paystatus'] == 1){ $succeed = 1; } echo $succeed; die;
响应那个一直请求 当验证通过时候 就 跳转 停止请求 支付完成。
