PHP微信红包API接口 - 快网idc优惠网

首先给大家看一看这个表格：

根据微信高级红包接口，开发PHP版本的API接口，现在进行主要代码分析。

红包接口调用请求代码，所有请求参数为必填参数与文档对应：

class Wxapi {

private $app_id = 'wxXXXXXXXXXXXX'; //公众账号appid，首先申请与之配套的公众账号

private $app_secret = 'XXXXXXXXXXXXXXXXXXXXXXXX';//公众号secret，用户获取用户授权token

private $app_mchid = 'XXXXXXXX';//商户号id

function __construct(){

//do sth here....

}

/**

* 微信支付

* @param string $openid 用户openid

*/

public function pay($re_openid)

{

include_once('WxHongBaoHelper.php');

$commonUtil = new CommonUtil();

$wxHongBaoHelper = new WxHongBaoHelper();

$wxHongBaoHelper->setParameter("nonce_str", $this->great_rand());//随机字符串，丌长于 32 位

$wxHongBaoHelper->setParameter("mch_billno", $this->app_mchid.date('YmdHis').rand(1000, 9999));//订单号

$wxHongBaoHelper->setParameter("mch_id", $this->app_mchid);//商户号

$wxHongBaoHelper->setParameter("wxappid", $this->app_id);

$wxHongBaoHelper->setParameter("nick_name", '红包');//提供方名称

$wxHongBaoHelper->setParameter("send_name", '红包');//红包发送者名称

$wxHongBaoHelper->setParameter("re_openid", $re_openid);//相对于医脉互通的openid

$wxHongBaoHelper->setParameter("total_amount", 100);//付款金额，单位分

$wxHongBaoHelper->setParameter("min_value", 100);//最小红包金额，单位分

$wxHongBaoHelper->setParameter("max_value", 100);//最大红包金额，单位分

$wxHongBaoHelper->setParameter("total_num", 1);//红包収放总人数

$wxHongBaoHelper->setParameter("wishing", '感谢您参与红包派发活动，祝您新年快乐！');//红包祝福诧

$wxHongBaoHelper->setParameter("client_ip", '127.0.0.1');//调用接口的机器 Ip 地址

$wxHongBaoHelper->setParameter("act_name", '红包活动');//活劢名称

$wxHongBaoHelper->setParameter("remark", '快来抢！');//备注信息

$postXml = $wxHongBaoHelper->create_hongbao_xml();

$url = 'https://api.mch.weixin.qq.com/mmpaymkttransfers/sendredpack';

$responseXml = $wxHongBaoHelper->curl_post_ssl($url, $postXml);

//用作结果调试输出

//echo htmlentities($responseXml,ENT_COMPAT,'UTF-8');

$responseObj = simplexml_load_string($responseXml, 'SimpleXMLElement', LIBXML_NOCDATA);

return $responseObj->return_code;

}
