最近做生日營銷，需要微信發紅包，特此從網上找了一篇教程
首先你的有個服務號,並且開通了微信支付,我在這就不說怎麽去申請和開通了,我是看了微信官方文檔後,想看官方文檔的朋友可以到下面這個鏈接

class WxRedPack { //配置參數信息 const SHANGHUHAO = "***********";//商戶號 const PARTNERKEY = "***********"; //核心支付函數,參數：請求地址和參數 functionpay($url, $obj) { $obj[‘nonce_str‘] = $this->create_noncestr(); //創建隨機字符串 $stringA = $this->create_qianming($obj, false); //創建簽名 $stringSignTemp = $stringA . "&key=2470f691aee2bfae92087c10e81cb4d0"; //簽名後加api $sign = strtoupper(md5($stringSignTemp)); //簽名加密並大寫 $obj[‘sign‘] = $sign; //將簽名傳入數組 $postXml = $this->arrayToXml($obj); //將參數轉為xml格式 $responseXml = $this->curl_post_ssl($url, $postXml); //提交請求 return $responseXml; } //生成簽名,參數：生成簽名的參數和是否編碼 function create_qianming($arr, $urlencode) {$buff = ""; ksort($arr); //對傳進來的數組參數裏面的內容按照字母順序排序，a在前面，z在最後（字典序） foreach ($arr as $k => $v) { if (null != $v && "null" != $v && "sign" != $k) { //簽名不要轉碼 if ($urlencode) { $v = urlencode($v); } $buff .= $k . "=" . $v . "&"; } } if (strlen($buff) > 0) { $reqPar = substr($buff, 0, strlen($buff) - 1); //去掉末尾符號“&” } return $reqPar; } //生成隨機字符串，默認32位 function create_noncestr($length = 32) { //創建隨機字符 $chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789"; $str = ""; for ($i = 0; $i < $length; $i++) { $str .= substr($chars, mt_rand(0, strlen($chars) - 1), 1); } return $str; } //數組轉xml function arrayToXml($arr) { $xml = "<xml>"; foreach ($arr as $key => $val) { if (is_numeric($val)) { $xml .= "<" . $key . ">" . $val . "</" . $key . ">"; } else { $xml .= "<" . $key . "><![CDATA[" . $val . "]]></" . $key . ">"; } } $xml .= "</xml>"; return $xml; } //post請求網站，需要證書 function curl_post_ssl($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); //這裏設置代理，如果有的話 curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false); //cert 與 key 分別屬於兩個.pem文件 //請確保您的libcurl版本是否支持雙向認證，版本高於7.20.1 curl_setopt($ch, CURLOPT_SSLCERT, dirname(__FILE__) . DIRECTORY_SEPARATOR . ‘cert‘ . DIRECTORY_SEPARATOR . ‘apiclient_cert.pem‘); curl_setopt($ch, CURLOPT_SSLKEY, dirname(__FILE__) . DIRECTORY_SEPARATOR . ‘cert‘ . DIRECTORY_SEPARATOR . ‘apiclient_key.pem‘); curl_setopt($ch, CURLOPT_CAINFO, dirname(__FILE__) . DIRECTORY_SEPARATOR . ‘cert‘ . 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; } } }
然後調用:
public function setredpack($moneys,$openid) { $money = $moneys; //最低1元，單位分 $sender = "******"; $obj2 = array(); $obj2[‘wxappid‘] = "**********"; //appid $obj2[‘mch_id‘] = "***********"; //商戶id $obj2[‘mch_billno‘] = "********" . date(‘YmdHis‘) . rand(1000, 9999);//商戶訂單號 $obj2[‘client_ip‘] = $_SERVER[‘REMOTE_ADDR‘]; $obj2[‘re_openid‘] = $openid; //接收紅包openid $obj2[‘total_amount‘] = $money; $obj2[‘min_value‘] = $money; $obj2[‘max_value‘] = $money; $obj2[‘total_num‘] = 1; $obj2[‘scene_id‘] = ‘PRODUCT_2‘; $obj2[‘nick_name‘] = $sender; $obj2[‘send_name‘] = $sender; $obj2[‘wishing‘] = "恭喜發財"; $obj2[‘act_name‘] = $sender ; $obj2[‘remark‘] = $sender ; $url = "https://api.mch.weixin.qq.com/mmpaymkttransfers/sendredpack";
$Wxpay = new WxRedPack();
$res = $wxpay->pay($url, $obj2);return $res;
}
另一個版本方法：
一個PHP文件搞定微信支付系列之現金紅包
網上的很多PHP微信支付接入教程都頗為復雜，且需要配置和引入較多的文件，本人通過整理後給出一個單文件版的，希望可以給各位想接入微信支付的帶來些許幫助和借鑒意義。
直接運行該文件即可給指定的微信用戶發送現金紅包。
需要註意的事項：
-
1.微信現金紅包要求必傳證書，需要到https://pay.weixin.qq.com 賬戶中心->賬戶設置->API安全->下載證書，然後修改代碼中的證書路徑
-
2.默認的使用場景是抽獎（即scene_id參數為PRODUCT_2），額度是1-200元，所以測試時的最低金額是1元。如需修改在產品中心->產品大全->現金紅包->產品設置中修改
-
3.該文件需放到支付授權目錄下，可以在微信支付商戶平臺->產品中心->開發配置中設置。
-
4.如提示簽名錯誤可以通過微信支付簽名驗證工具進行驗證：https://pay.weixin.qq.com/wik...
-
5.錯誤碼參照 ：https://pay.weixin.qq.com/wik...
