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：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39

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：

1 2 3 4 5 6 7 8 9 10 11

/** ?*?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：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35

/** 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：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32

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：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

@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'); }
