本文实例讲述了php版微信发红包接口用法。分享给大家供大家参考，具体如下：

微信红包功能我相信各位朋友都知道吧,但如果我们要把红包集成到网站那么要如何来做呢?这里小编就来为各位分享一个php 微信发红包接口测试实例,希望文章能够帮助到各位朋友

下面是一个类,使用方法:

$arr['openid']='ojgTTt8oF9VdYcGsJMACHpA-jy1U'; $arr['hbname']="提现申请"; $arr['body']="您的提现申请已经成功"; $arr['fee']=1; $comm = new Common_util_pub(); $re = $comm->sendhongbaoto($arr); var_dump($re);

注意证书位置和 商户后台设置的key需要修改.

<"Content-type: text/html; charset=utf-8"); class Common_util_pub { /** * hbname 红包名称 fee 红包金额 /元 body 内容 openid 微信用户id * @param undefined $arr * * @return */ public function sendhongbaoto($arr){ //$comm = new Common_util_pub(); $data['mch_id'] = '120005402'; $data['mch_billno'] = '120005402'.date("Ymd",time()).date("His",time()).rand(1111,9999); $data['nonce_str'] = self::createNoncestr(); $data['re_openid'] = $arr['openid']; $data['wxappid'] = 'wx8axxxxxbac4905'; $data['nick_name'] = $arr['hbname']; $data['send_name'] = $arr['hbname']; $data['total_amount'] = $arr['fee']*100; $data['min_value'] = $arr['fee']*100; $data['max_value'] = $arr['fee']*100; $data['total_num'] = 1; $data['client_ip'] = $_SERVER['REMOTE_ADDR']; $data['act_name'] = '测试活动'; $data['remark'] = '备注一下'; $data['wishing'] = $arr['body']; if(!$data['re_openid']) { $rearr['return_msg']='缺少用户openid'; return $rearr; } $data['sign'] = self::getSign($data); $xml = self::arrayToXml($data); //var_dump($xml); $url ="https://api.mch.weixin.qq.com/mmpaymkttransfers/sendredpack"; $re = self::wxHttpsRequestPem($xml,$url); $rearr = self::xmlToArray($re); return $rearr; } function trimString($value) { $ret = null; if (null != $value) { $ret = $value; if (strlen($ret) == 0) { $ret = null; } } return $ret; } /** * 作用：产生随机字符串，不长于32位 */ public function createNoncestr( $length = 32 ) { $chars = "abcdefghijklmnopqrstuvwxyz0123456789"; $str =""; for ( $i = 0; $i < $length; $i++ ) { $str.= substr($chars, mt_rand(0, strlen($chars)-1), 1); } return $str; } /** * 作用：格式化参数，签名过程需要使用 */ function formatBizQueryParaMap($paraMap, $urlencode) { $buff = ""; ksort($paraMap); foreach ($paraMap as $k => $v) { if($urlencode) { $v = urlencode($v); } //$buff .= strtolower($k) .
