最近做生日营销，需要微信发红包，特此从网上找了一篇教程
首先你的有个服务号,并且开通了微信支付,我在这就不说怎么去申请和开通了,我是看了微信官方文档后,想看官方文档的朋友可以到下面这个链接
https://pay.weixin.qq.com/wiki/doc/api/tools/cash_coupon.php?chapter=13_1
class WxRedPack { //配置参数信息 const SHANGHUHAO = "***********";//商户号 const PARTNERKEY = "***********"; //核心支付函数,参数：请求地址和参数 function pay($url, $obj) { $obj[‘nonce_str‘] = $this->create_noncestr(); //创建随机字符串 $stringA = $this->create_qianming($obj, false); //创建签名 $stringSignTemp = $stringA . "&key=2470f691aee2bfae92087c10e81cb4d0"; //签名后加api $sign = strtoupper(md5($stringSignTemp)); //签名加密并大写 $obj[‘sign‘] = $sign; //将签名传入数组 $postXml = $this->arrayToXml($obj); //将参数转为xml格式 $responseXml = $this->curl_post_ssl($url, $postXml); //提交请求 return $responseXml; } //生成签名,参数：生成签名的参数和是否编码 function create_qianming($arr, $urlencode) { $buff = ""; ksort($arr); //对传进来的数组参数里面的内容按照字母顺序排序，a在前面，z在最后（字典序） foreach ($arr as $k => $v) { if (null != $v && "null" != $v && "sign" != $k) { //签名不要转码 if ($urlencode) { $v = urlencode($v); } $buff .= $k . "=" . $v . "&"; } } if (strlen($buff) > 0) { $reqPar = substr($buff, 0, strlen($buff) - 1); //去掉末尾符号“&” } return $reqPar; } //生成随机字符串，默认32位 function create_noncestr($length = 32) { //创建随机字符 $chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789"; $str = ""; for ($i = 0; $i < $length; $i++) { $str .= substr($chars, mt_rand(0, strlen($chars) - 1), 1); } return $str; } //数组转xml function arrayToXml($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 $xml; } //post请求网站，需要证书 function curl_post_ssl($url, $vars, $second = 30, $aHeader = array()) { $ch = curl_init(); //超时时间 curl_setopt($ch, CURLOPT_TIMEOUT, $second); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); //这里设置代理，如果有的话 curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false); //cert 与 key 分别属于两个.pem文件 //请确保您的libcurl版本是否支持双向认证，版本高于7.20.1 curl_setopt($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; } } }
然后调用:
public function setredpack($moneys,$openid) { $money = $moneys; //最低1元，单位分 $sender = "******"; $obj2 = array(); $obj2[‘wxappid‘] = "**********"; //appid $obj2[‘mch_id‘] = "***********"; //商户id $obj2[‘mch_billno‘] = "********" . date(‘YmdHis‘) . rand(1000, 9999);//商户订单号 $obj2[‘client_ip‘] = $_SERVER[‘REMOTE_ADDR‘]; $obj2[‘re_openid‘] = $openid; //接收红包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‘] = "恭喜发财"; $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;
}
另一个版本方法：
网上的很多PHP微信支付接入教程都颇为复杂，且需要配置和引入较多的文件，本人通过整理后给出一个单文件版的，希望可以给各位想接入微信支付的带来些许帮助和借鉴意义。
直接运行该文件即可给指定的微信用户发送现金红包。
需要注意的事项：
1.微信现金红包要求必传证书，需要到https://pay.weixin.qq.com 账户中心->账户设置->API安全->下载证书，然后修改代码中的证书路径
2.默认的使用场景是抽奖（即scene_id参数为PRODUCT_2），额度是1-200元，所以测试时的最低金额是1元。如需修改在产品中心->产品大全->现金红包->产品设置中修改
3.该文件需放到支付授权目录下，可以在微信支付商户平台->产品中心->开发配置中设置。
4.如提示签名错误可以通过微信支付签名验证工具进行验证：https://pay.weixin.qq.com/wik...
5.错误码参照 ：https://pay.weixin.qq.com/wik...
