php实现微信发红包功能

本文实例为大家分享了PHP实现微信发红包功能的具体代码，供大家参考，具体内容如下

微信商家后台-现金红包开发：

rush:PHP;"> create_noncestr(); //创建随机字符串 $stringA = $this->create_qianming($obj,false); //创建签名 $stringSignTemp = $stringA."&key=leFyTOXWzUEXxfp47WOu5xxxxxx"; //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 var_dump($postXml); $responseXml = $this->curl_post_ssl($url,$postXml); //提交请求 var_dump($responseXml); 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,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) {
$xml = "";
foreach ($arr as $key=>$val) {
if (is_numeric($val)) {
$xml.="<".$key.">".$val."</".$key.">";
} else {
$xml.="<".$key."><![CDATA[".$val."]]></".$key.">";
}
}
$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($ch,CURLOPT_SSLCERT,dirname(FILE).DIRECTORY_SEParaTOR.
'zhengshu'.DIRECTORY_SEParaTOR.'apiclient_cert.pem');
curl_setopt($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;
}
}

}

证书文件：

请在微信商户后台-API安全下载，PHP请使用PHP的证书文件

微信红包调用测试文件：

rush:PHP;"> PHP require 'wxpay.class.PHP';

//数组参数 $money = 100; //最低1元，单位分 $sender = "晨缘房产"; $obj2 = array(); $obj2['wxappid'] = ""; //appid $obj2['mch_id'] = "";　　//商户id $obj2['mch_billno'] = "商户id".date('YmdHis').rand(1000,9999);　　//组合成28位，根据官方开发文档，可以自行设置 $obj2['client_ip'] = $_SERVER['REMOTE_ADDR']; $obj2['re_openid'] = "oUxO6v26wdyMHThD9kfDW6NB_xbE";　　//接收红包openid $obj2['total_amount'] = $money; $obj2['min_value'] = $money; $obj2['max_value'] = $money; $obj2['total_num'] = 1; $obj2['nick_name'] = $sender; $obj2['send_name'] = $sender; $obj2['wishing'] = "恭喜发财"; $obj2['act_name'] = $sender."红包"; $obj2['remark'] = $sender."红包";

$url = "https://api.mch.weixin.qq.com/mmpaymkttransfers/sendredpack";
$wxpay = new wxPay();
$res = $wxpay->pay($url,$obj2);
var_dump($res);
