這篇文章主要介紹了PHP微信紅包API接口，針對微信高級紅包接口，開發(fā)PHP版本的API接口的主要代碼進行分析，感興趣的小伙伴們可以參考一下

首先給大家看一看這個表格：

根據(jù)微信高級紅包接口，開發(fā)PHP版本的API接口，現(xiàn)在進行主要代碼分析。

紅包接口調(diào)用請求代碼，所有請求參數(shù)為必填參數(shù)與文檔對應：

class Wxapi { private $app_id = 'wxXXXXXXXXXXXX'; //公眾賬號appid，首先申請與之配套的公眾賬號 private $app_secret = 'XXXXXXXXXXXXXXXXXXXXXXXX';//公眾號secret，用戶獲取用戶授權(quán)token private $app_mchid = 'XXXXXXXX';//商戶號id function __construct(){ //do sth here.... } /** * 微信支付 * @param string $openid 用戶openid */ public function pay($re_openid) { include_once('WxHongBaoHelper.php'); $commonUtil = new CommonUtil(); $wxHongBaoHelper = new WxHongBaoHelper(); $wxHongBaoHelper->setParameter("nonce_str", $this->great_rand());//隨機字符串，丌長于 32 位 $wxHongBaoHelper->setParameter("mch_billno", $this->app_mchid.date('YmdHis').rand(1000, 9999));//訂單號 $wxHongBaoHelper->setParameter("mch_id", $this->app_mchid);//商戶號 $wxHongBaoHelper->setParameter("wxappid", $this->app_id); $wxHongBaoHelper->setParameter("nick_name", '紅包');//提供方名稱 $wxHongBaoHelper->setParameter("send_name", '紅包');//紅包發(fā)送者名稱 $wxHongBaoHelper->setParameter("re_openid", $re_openid);//相對于醫(yī)脈互通的openid $wxHongBaoHelper->setParameter("total_amount", 100);//付款金額，單位分 $wxHongBaoHelper->setParameter("min_value", 100);//最小紅包金額，單位分 $wxHongBaoHelper->setParameter("max_value", 100);//最大紅包金額，單位分 $wxHongBaoHelper->setParameter("total_num", 1);//紅包収放總?cè)藬?shù) $wxHongBaoHelper->setParameter("wishing", '感謝您參與紅包派發(fā)活動，祝您新年快樂！');//紅包祝福詫 $wxHongBaoHelper->setParameter("client_ip", '127.0.0.1');//調(diào)用接口的機器 Ip 地址 $wxHongBaoHelper->setParameter("act_name", '紅包活動');//活勱名稱 $wxHongBaoHelper->setParameter("remark", '快來搶！');//備注信息 $postXml = $wxHongBaoHelper->create_hongbao_xml(); $url = 'https://api.mch.weixin.qq.com/mmpaymkttransfers/sendredpack'; $responseXml = $wxHongBaoHelper->curl_post_ssl($url, $postXml); //用作結(jié)果調(diào)試輸出 //echo htmlentities($responseXml,ENT_COMPAT,'UTF-8'); $responseObj = simplexml_load_string($responseXml, 'SimpleXMLElement', LIBXML_NOCDATA); return $responseObj->return_code; }

獲取隨機字符串方法：

/** * 生成隨機數(shù) */ public function great_rand(){ $str = '1234567890abcdefghijklmnopqrstuvwxyz'; for($i=0;$i

?簽名算法：

/** 例如： appid： wxd111665abv58f4f mch_id： 10000100 device_info： 1000 Body： test nonce_str： ibuaiVcKdpRxkhJA 第一步：對參數(shù)按照 key=value 的格式，并按照參數(shù)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：拼接支付密鑰： 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("密鑰不能為空！" . "
"); } if($this->check_sign_parameters() == false) { //檢查生成簽名參數(shù) throw new SDKRuntimeException("生成簽名參數(shù)缺失！" . "
"); } $commonUtil = new CommonUtil(); ksort($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請求以及發(fā)送證書：

function curl_post_ssl($url, $vars, $second=30,$aHeader=array()) { $ch = curl_init(); //超時時間 curl_setopt($ch,CURLOPT_TIMEOUT,$second); curl_setopt($ch,CURLOPT_RETURNTRANSFER, 1); //這里設置代理，如果有的話 curl_setopt($ch,CURLOPT_URL,$url); curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,false); curl_setopt($ch,CURLOPT_SSL_VERIFYHOST,false); //cert 與 key 分別屬于兩個.pem文件 //請確保您的libcurl版本是否支持雙向認證，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; } }
