后期还是会增加在一起的把这个CLASS做起来，网上资源很多，但是都是有一定基础的人去看看改改可以，对于没有接触刚刚接触的新手还是需要给予支持的。帮助用户屡屡思路。
再来一份：
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 $app_mchid = 'XXXXXXXX';//商户号id
function __construct(){
//do sth here....
}
public function pay($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：
public function great_rand(){
$str = '1234567890abcdefghijklmnopqrstuvwxyz';
for($i=0;$i<30;$i++){
$j=rand(0,35);
$t1 .= $str[$j];
}
return $t1;
}
签名算法：
protected function get_sign(){
define('PARTNERKEY',"QSRXXXXXXXXXXXXXXXXXXXXX");
try {
if (null == PARTNERKEY || "" == PARTNERKEY ) {
throw new SDKRuntimeException("密钥不能为空！" . "
");
}
if($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:$errorn";
curl_close($ch);
return false;
}
}
入口文件：
@require "pay.php";
//获取用户信息
$get = $_GET['param'];
$code = $_GET['code'];
//判断code是否存在
if($get=='access_token' && !empty($code)){
$param['param'] = 'access_token';
$param['code'] = $code;
$packet = new Packet();
//获取用户openid信息
$userinfo = $packet->_route('userinfo',$param);
if(empty($userinfo['openid'])){
exit("NOAUTH");
}
//调取支付方法
$packet->_route('wxpacket',array('openid'=>$userinfo['openid']));
}else{
$packet->_route('userinfo');
}
以上就是本文的全部内容，希望对大家学习PHP程序设计有所帮助，也希望大家多多支持考高分网。
