證書文件：

請在微信商戶後臺-API安全下載，PHP請使用php的證書文件

 

微信紅包調用測試文件：

<?php
require 'wxpay.class.php';

//數組參數
$money = 100; //最低1元，單位分
$sender = "晨緣房產";
$obj2 = array();
$obj2['wxappid'] = ""; //appid
$obj2['mch_id'] = "";　　//商戶id
$obj2['mch_billno'] = "商戶id".date('YmdHis').rand(1000,9999);　　//組合成28位，根據官方開發文檔，能夠自行設置
$obj2['client_ip'] = $_SERVER['REMOTE_ADDR'];
$obj2['re_openid'] = "oUxO6v26wdyMHThD9kfDW6NB_xbE";　　//接收紅包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'] = "恭喜發財";
$obj2['act_name'] = $sender."紅包";
$obj2['remark'] = $sender."紅包";

$url = "https://api.mch.weixin.qq.com/mmpaymkttransfers/sendredpack";
$wxpay = new wxPay();
$res = $wxpay->pay($url, $obj2);
var_dump($res);

 

纔開始作微信開發，測試了一個下午，汗！！！
