证书文件:

请在微信商户后台-API安全下载,PHP请使用php的证书文件

微信红包调用测试文件:

<?php require 'wxpay.class.php';<br><br>//数组参数 $money = 100; //最低1元,单位分 $sender = "晨缘房产"; $obj2 = array(); $obj2['wxappid'] = ""; //appid $obj2['mch_id'] = "";  //商户id $obj2['mch_billno'] = "商户id".date('YmdHis').rand(1000,9999);  //组合成28位,根据官方开发文档,可以自行设置 $obj2['client_ip'] = $_SERVER['REMOTE_ADDR']; $obj2['re_openid'] = "oUxO6v26wdyMHThD9kfDW6NB_xbE";  //接收红包openid $obj2['total_amount'] = $money; $obj2['min_value'] = $money; $obj2['max_value'] = $money; $obj2['total_num'] = 1; $obj2['nick_name'] = $sender; $obj2['send_name'] = $sender; $obj2['wishing'] = "恭喜发财"; $obj2['act_name'] = $sender."红包"; $obj2['remark'] = $sender."红包"; $url = "https://api.mch.weixin.qq.com/mmpaymkttransfers/sendredpack"; $wxpay = new wxPay(); $res = $wxpay->pay($url, $obj2); var_dump($res);
