首先給大家看一看這個表格：

根據微信高級紅包接口，開發(fā)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(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);//紅包収放總人數   $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(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:$errorn";    curl_close($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'); }
