PHP微信红包API接口
这篇文章主要介绍了PHP微信红包API接口,针对微信高级红包接口,开发PHP版本的API接口的主要代码进行分析,感兴趣的小伙伴们可以参考一下
首先给大家看一看这个表格:
根据微信高级红包接口,开发PHP版本的API接口,现在进行主要代码分析。
红包接口调用请求代码,所有请求参数为必填参数与文档对应:
class Wxapi { private $app_id = 'wxXXXXXXXXXXXX'; //公众账号appid,首先申请与之配套的公众账号 private $app_secret = 'XXXXXXXXXXXXXXXXXXXXXXXX';//公众号secret,用户获取用户授权token private $app_mchid = 'XXXXXXXX';//商户号id function __construct(){ //do sth here.... } /** * 微信支付 * @param string $openid 用户openid */ public function pay($re_openid) { include_once('WxHongBaoHelper.php'); $commonUtil = new CommonUtil(); $wxHongBaoHelper = new WxHongBaoHelper(); $wxHongBaoHelper->setParameter("nonce_str", $this->great_rand());//随机字符串,丌长于 32 位 $wxHongBaoHelper->setParameter("mch_billno", $this->app_mchid.date('YmdHis').rand(1000, 9999));//订单号 $wxHongBaoHelper->setParameter("mch_id", $this->app_mchid);//商户号 $wxHongBaoHelper->setParameter("wxappid", $this->app_id); $wxHongBaoHelper->setParameter("nick_name", '红包');//提供方名称 $wxHongBaoHelper->setParameter("send_name", '红包');//红包发送者名称 $wxHongBaoHelper->setParameter("re_openid", $re_openid);//相对于医脉互通的openid $wxHongBaoHelper->setParameter("total_amount", 100);//付款金额,单位分 $wxHongBaoHelper->setParameter("min_value", 100);//最小红包金额,单位分 $wxHongBaoHelper->setParameter("max_value", 100);//最大红包金额,单位分 $wxHongBaoHelper->setParameter("total_num", 1);//红包収放总人数 $wxHongBaoHelper->setParameter("wishing", '感谢您参与红包派发活动,祝您新年快乐!');//红包祝福诧 $wxHongBaoHelper->setParameter("client_ip", '127.0.0.1');//调用接口的机器 Ip 地址 $wxHongBaoHelper->setParameter("act_name", '红包活动');//活劢名称 $wxHongBaoHelper->setParameter("remark", '快来抢!');//备注信息 $postXml = $wxHongBaoHelper->create_hongbao_xml(); $url = 'https://api.mch.weixin.qq.com/mmpaymkttransfers/sendredpack'; $responseXml = $wxHongBaoHelper->curl_post_ssl($url, $postXml); //用作结果调试输出 //echo htmlentities($responseXml,ENT_COMPAT,'UTF-8'); $responseObj = simplexml_load_string($responseXml, 'SimpleXMLElement', LIBXML_NOCDATA); return $responseObj->return_code; }
获取随机字符串方法:
/** * 生成随机数 */ public function great_rand(){ $str = '1234567890abcdefghijklmnopqrstuvwxyz'; for($i=0;$i
签名算法:
/**
例如:
appid: wxd111665abv58f4f
mch_id: 10000100
device_info: 1000
Body: test
nonce_str: ibuaiVcKdpRxkhJA
第一步:对参数按照 key=value 的格式,并按照参数名 ASCII 字典序排序如下:
stringA="appid=wxd930ea5d5a258f4f&body=test&device_info=1000&mch_i
d=10000100&nonce_str=ibuaiVcKdpRxkhJA";
第二步:拼接支付密钥:
stringSignTemp="stringA&key=192006250b4c09247ec02edce69f6a2d"
sign=MD5(stringSignTemp).toUpperCase()="9A0A8659F005D6984697E2CA0A
9CF3B7"
*/
protected function get_sign(){
define('PARTNERKEY',"QSRXXXXXXXXXXXXXXXXXXXXX");
try {
if (null == PARTNERKEY || "" == PARTNERKEY ) {
throw new SDKRuntimeException("密钥不能为空!" . "
");
}
if($this->check_sign_parameters() == false) { //检查生成签名参数
throw new SDKRuntimeException("生成签名参数缺失!" . "
");
}
$commonUtil = new CommonUtil();
ksort($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请求以及发送证书:
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; } }
