微信红包api接口实现小编以前有介绍过相关的教程,不过这次好像有一点不一样下面我们来看看,教程比上次的更完整。
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 $responseObj->return_code;
}
片段二、
//生成红包接口XML信息
/*
*/
function create_hongbao_xml($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。
