PHP微信紅包API介面_php執行個體

首先給大家看一看這個表格：

根據微信進階紅包介面，開發PHP版本的API介面，現在進行主要程式碼分析。

紅包介面調用請求代碼，所有請求參數為必填參數與文檔對應：

class Wxapi { private $app_id = 'wxXXXXXXXXXXXX'; //公眾帳號appid，首先申請與之配套的公眾帳號 private $app_secret = 'XXXXXXXXXXXXXXXXXXXXXXXX';//公眾號secret，使用者擷取使用者授權token private $app_mchid = 'XXXXXXXX';//商戶號id function __construct(){ //do sth here.... } /**  * 微信支付  * @param string $openid 使用者openid  */ public function pay($re_openid) {  include_once('WxHongBaoHelper.php');  $commonUtil = new CommonUtil();  $wxHongBaoHelper = new WxHongBaoHelper();  $wxHongBaoHelper->setParameter("nonce_str", $this->great_rand());//隨機字串，丌長於 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');//紅包寄件者名稱  $wxHongBaoHelper->setParameter("re_openid", $re_openid);//相對於醫脈互連的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');//調用介面的機器 Ip 地址  $wxHongBaoHelper->setParameter("act_name", '紅包活動');//活勱名稱  $wxHongBaoHelper->setParameter("remark", '快來搶！');//備忘資訊  $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; }

擷取隨機字串方法：

/** * 產生隨機數 */  public function great_rand(){ $str = '1234567890abcdefghijklmnopqrstuvwxyz'; for($i=0;$i<30;$i++){  $j=rand(0,35);  $t1 .= $str[$j]; } return $t1; }

 簽名演算法：

/**例如：appid： wxd111665abv58f4fmch_id： 10000100device_info： 1000Body： testnonce_str： ibuaiVcKdpRxkhJA第一步：對參數按照 key=value 的格式，並按照參數名 ASCII 字典序排序如下：stringA="appid=wxd930ea5d5a258f4f&body=test&device_info=1000&mch_id=10000100&nonce_str=ibuaiVcKdpRxkhJA";第二步：拼接支付密鑰：stringSignTemp="stringA&key=192006250b4c09247ec02edce69f6a2d"sign=MD5(stringSignTemp).toUpperCase()="9A0A8659F005D6984697E2CA0A9CF3B7"*/protected function get_sign(){ define('PARTNERKEY',"QSRXXXXXXXXXXXXXXXXXXXXX"); try {  if (null == PARTNERKEY || "" == PARTNERKEY ) {   throw new SDKRuntimeException("密鑰不可為空！" . "<br>");  }  if($this->check_sign_parameters() == false) { //檢查產生簽名參數   throw new SDKRuntimeException("產生簽名參數缺失！" . "<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請求以及發送認證：

function curl_post_ssl($url, $vars, $second=30,$aHeader=array()){ $ch = curl_init(); //逾時時間 curl_setopt($ch,CURLOPT_TIMEOUT,$second); curl_setopt($ch,CURLOPT_RETURNTRANSFER, 1); //這裡設定代理，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 分別屬於兩個.pem檔案 //請確保您的libcurl版本是否支援雙向認證，版本高於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; }}

入口檔案：

@require "pay.php";//擷取使用者資訊$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(); //擷取使用者openid資訊 $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');}
