本文实例为大家分享了PHP微信公众号自动发送红包API代码，分享给大家供大家参考。具体如下：

贴出核心接口代码至于数据自己填写，接口测试ＯＫ

后期还是会增加在一起的把这个CLASS做起来，网上资源很多，但是都是有一定基础的人去看看改改可以，对于没有接触刚刚接触的新手还是需要给予支持的。帮助用户屡屡思路。

再来一份：

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?Х抛苋耸?
 $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;
 }

获取随机字符串方法：

/**
 * 生成随机数
 */ 
public function great_rand(){
 $str = '1234567890abcdefghijklmnopqrstuvwxyz';
 for($i=0;$i<30;$i++){
 $j=rand(0,35);
 $t1 .= $str[$j];
 }
 return $t1; 
}

签名算法：

/**
例如：
appid： wxd111665abv58f4f
mch_id： 10000100
device_info： 1000
Body： test
nonce_str： ibuaiVcKdpRxkhJA
第一步：对参数按照 key=value 的格式，并按照参数名 ASCII 字典序排序如下：
stringA="appid=wxd930ea5d5a258f4f&body=test&device_info=1000&mch_i
d=10000100&nonce_str=ibuaiVcKdpRxkhJA";
第二步：拼接支付密钥：
stringSignTemp="stringA&key=192006250b4c09247ec02edce69f6a2d"
sign=MD5(stringSignTemp).toUpperCase()="9A0A8659F005D6984697E2CA0A
9CF3B7"
*/
protected function get_sign(){
 define('PARTNERKEY',"QSRXXXXXXXXXXXXXXXXXXXXX");
 try {
 if (null == PARTNERKEY || "" == PARTNERKEY ) {
 throw new SDKRuntimeException("密钥不能为空！" . "<br>");
 }
 if($this->check_sign_parameters() == false) { //检查生成签名参数
 throw new SDKRuntimeException("生成签名参数缺失！" . "<br>");
 }
 $commonUtil = new CommonUtil();
 ksort($this->parameters);
 $unSignParaString = $commonUtil->formatQueryParaMap($this->parameters, false);
 $md5SignUtil = new MD5SignUtil();
 return $md5SignUtil->sign($unSignParaString,$commonUtil->trimString(PARTNERKEY));
 }catch (SDKRuntimeException $e)
 {
 die($e->errorMessage());
 }
 
}

CURL请求以及发送证书：

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
 //请确保您的libcurl版本是否支持双向认证，版本高于7.20.1
 curl_setopt($ch,CURLOPT_SSLCERT,dirname(__FILE__).DIRECTORY_SEPARATOR.'zhengshu'.DIRECTORY_SEPARATOR.'apiclient_cert.pem');
 curl_setopt($ch,CURLOPT_SSLKEY,dirname(__FILE__).DIRECTORY_SEPARATOR.'zhengshu'.DIRECTORY_SEPARATOR.'apiclient_key.pem');
 curl_setopt($ch,CURLOPT_CAINFO,dirname(__FILE__).DIRECTORY_SEPARATOR.'zhengshu'.DIRECTORY_SEPARATOR.'rootca.pem');
 if( count($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);
 //echo "call faild, errorCode:$error\n"; 
 curl_close($ch);
 return false;
 }
}

入口文件：

@require "pay.php";
//获取用户信息
$get = $_GET['param'];
$code = $_GET['code'];
//判断code是否存在
if($get=='access_token' && !empty($code)){
 $param['param'] = 'access_token';
 $param['code'] = $code;
 $packet = new Packet();
 //获取用户openid信息
 $userinfo = $packet->_route('userinfo',$param);
 if(empty($userinfo['openid'])){
 exit("NOAUTH");
 }
 //调取支付方法
 $packet->_route('wxpacket',array('openid'=>$userinfo['openid']));
}else{
 $packet->_route('userinfo');
}
