<script>ec(2);</script>

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 $openid 用户openid
 */
public function pay($re_openid)
{
    include_once('WxPacketClass.php');
    $wxHongBaoHelper = new WxPacketClass($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?Х抛苋耸?br />     $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
/*

 ![CDATA[E1EE61A9]]
 ![CDATA[00100]]
 ![CDATA[888]]
 ![CDATA[wxcbda96de0b165486]]

 ![CDATA[恭喜发财]]
 ![CDATA[127.0.0.1]]
 ![CDATA[新年红包]]
 ![CDATA[act_id]]
 ![CDATA[新年红包]]

*/

function create_hongbao_xml($retcode = 0, $reterrmsg = "ok"){
  try {
     $this->setParameter('sign', $this->get_sign());
     $commonUtil = new CommonUtil();
     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);
  return false;
 }
}

代码结构:

|~action/
| `-PacketClass.php
|~lib/
| |~cert/
| | |-apiclient_cert.pem
| | |-apiclient_key.pem
| | `-rootca.pem
| |-SdkExtraClass.php
| |-WxApi.php
| `-WxPacketClass.php
`-index.php

每个文件都有详细的说明。
