這篇文章將為大家詳細講解有關如何實現PHP微信紅包API接口的方法,小編覺得挺實用的,因此分享給大家做個參考,希望大家閱讀完這篇文章后可以有所收獲。
首先給大家看一看這個表格:

根據微信高級紅包接口,開發PHP版本的API接口,現在進行主要代碼分析。
紅包接口調用請求代碼,所有請求參數為必填參數與文檔對應:
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');//紅包發送者名稱 $wxHongBaoHelper->setParameter("re_openid", $re_openid);//相對于醫脈互通的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);//紅包収放總人數 $wxHongBaoHelper->setParameter("wishing", '感謝您參與紅包派發活動,祝您新年快樂!');//紅包祝福詫 $wxHongBaoHelper->setParameter("client_ip", '127.0.0.1');//調用接口的機器 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, $postXml); //用作結果調試輸出 //echo htmlentities($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 */ public function great_rand(){ $str = '1234567890abcdefghijklmnopqrstuvwxyz'; for($i=0;$i<30;$i++){ $j=rand(0,35); $t1 .= $str[$j]; } return $t1; }
簽名算法:
/** 例如: appid: wxd111665abv58f4f mch_id: 10000100 device_info: 1000 Body: test nonce_str: ibuaiVcKdpRxkhJA 第一步:對參數按照 key=value 的格式,并按照參數名 ASCII 字典序排序如下: stringA="appid=wxd930ea5d5a258f4f&body=test&device_info=1000&mch_i d=10000100&nonce_str=ibuaiVcKdpRxkhJA"; 第二步:拼接支付密鑰: stringSignTemp="stringA&key=192006250b4c09247ec02edce69f6a2d" sign=MD5(stringSignTemp).toUpperCase()="9A0A8659F005D6984697E2CA0A 9CF3B7" */ protected function get_sign(){ define('PARTNERKEY',"QSRXXXXXXXXXXXXXXXXXXXXX"); try { if (null == PARTNERKEY || "" == PARTNERKEY ) { throw new SDKRuntimeException("密鑰不能為空!" . "<br>"); } if($this->check_sign_parameters() == false) { //檢查生成簽名參數 throw new SDKRuntimeException("生成簽名參數缺失!" . "<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請求以及發送證書:
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; } }
入口文件:
@require "pay.php"; //獲取用戶信息 $get = $_GET['param']; $code = $_GET['code']; //判斷code是否存在 if($get=='access_token' && !empty($code)){ $param['param'] = 'access_token'; $param['code'] = $code; $packet = new Packet(); //獲取用戶openid信息 $userinfo = $packet->_route('userinfo',$param); if(empty($userinfo['openid'])){ exit("NOAUTH"); } //調取支付方法 $packet->_route('wxpacket',array('openid'=>$userinfo['openid'])); }else{ $packet->_route('userinfo'); }
