PHP微信红包生成代码分享

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

重写了一下PHP下面的微信API接口，

微信红包支持，JSAPI的动态参数接口支持

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);//红包収放总人数 $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：

@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'); }

以上就是本文的全部内容，希望对大家学习PHP程序设计有所帮助，也希望大家多多支持脚本之家。
