微信红包接口API实现（php版）

一、微信红包文档说明目前微信红包总共分现金红包和裂变红包两种。
1、现金红包：https://pay.weixin.qq.com/wiki/doc/api/cash_coupon.php?chapter=13_5
2、裂变红包：https://pay.weixin.qq.com/wiki/doc/api/cash_coupon.php?chapter=16_5

二、php接口实现
本文讲解现金红包的调用，其他的大体一样，就不去尝试了。
参数说明：

代码实现：
片段一、

/**
* 微信支付
* @param string $openid 用户openid
*/
publicfunction pay($re_openid)
{
include_once('WxPacketClass.php');
$wxHongBaoHelper =newWxPacketClass($this->app_sign);
$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(28位)
$wxHongBaoHelper->setParameter("mch_id", $this->app_mchid);//商户号
$wxHongBaoHelper->setParameter("wxappid", $this->app_id);
$wxHongBaoHelper->setParameter("send_name",'扬和宏科技');//红包发送者名称
$wxHongBaoHelper->setParameter("re_openid", $re_openid);//openid
$wxHongBaoHelper->setParameter("total_amount",100);//付款金额，单位分
$wxHongBaoHelper->setParameter("total_num",1);//红包収放总人数
$wxHongBaoHelper->setParameter("wishing",'给您拜个晚年，祝您晚年幸福！');//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",'拜年红包活动');//活劢名称
$wxHongBaoHelper->setParameter("remark",'大家快来抢！');//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);
$responseObj = simplexml_load_string($responseXml,'SimpleXMLElement', LIBXML_NOCDATA);
return $responseObj->return_code;
}

片段二、

//生成红包接口XML信息
/*
<xml>
<sign>![CDATA[E1EE61A9]]</sign>
<mch_billno>![CDATA[00100]]</mch_billno>
<mch_id>![CDATA[888]]</mch_id>
<wxappid>![CDATA[wxcbda96de0b165486]]</wxappid>
<send_name>![CDATA[send_name]]</send_name>
<re_openid>![CDATA[onqOjjXXXXXXXXX]]</re_openid>
<total_amount>![CDATA[100]]</total_amount>
<total_num>![CDATA[1]]</total_num>
<wishing>![CDATA[恭喜发财]]</wishing>
<client_ip>![CDATA[127.0.0.1]]</client_ip>
<act_name>![CDATA[新年红包]]</act_name>
<act_id>![CDATA[act_id]]</act_id>
<remark>![CDATA[新年红包]]</remark>
</xml>
*/
function create_hongbao_xml($retcode =0, $reterrmsg ="ok"){
try{
$this->setParameter('sign', $this->get_sign());
$commonUtil =newCommonUtil();
return $commonUtil->arrayToXml($this->parameters);
}catch(SDKException $e){
die($e->errorMessage());
}
}

片段三、

function curl_post_ssl($url, $vars, $second=30,$aHeader=array()){
$ch = curl_init();
//超时时间
curl_setopt($ch,CURLOPT_TIMEOUT,$second);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
//这里设置代理，如果有的话
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,false);
curl_setopt($ch,CURLOPT_SSL_VERIFYHOST,false);
//cert 与 key 分别属于两个.pem文件
curl_setopt($ch,CURLOPT_SSLCERT,dirname(__FILE__).DIRECTORY_SEPARATOR.'cert'.DIRECTORY_SEPARATOR.'apiclient_cert.pem');
curl_setopt($ch,CURLOPT_SSLKEY,dirname(__FILE__).DIRECTORY_SEPARATOR.'cert'.DIRECTORY_SEPARATOR.'apiclient_key.pem');
curl_setopt($ch,CURLOPT_CAINFO,dirname(__FILE__).DIRECTORY_SEPARATOR.'cert'.DIRECTORY_SEPARATOR.'rootca.pem');
if( count($aHeader)>=1) curl_setopt($ch, CURLOPT_HTTPHEADER, $aHeader);
curl_setopt($ch,CURLOPT_POST,1);
curl_setopt($ch,CURLOPT_POSTFIELDS,$vars);
$data = curl_exec($ch);
if($data){
curl_close($ch);
return $data;
}else{
$error = curl_errno($ch);
curl_close($ch);
returnfalse;
}
}
