PHP微信红包API接口


            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 = 'http://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<30;$i++){

  $j=rand(0,35);

  $t1 .= $str[$j];

 }

 return $t1; 

}





 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！" . "<br>");

  }

  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！" . "<br>");

  }

  $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;

 }

}





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');

}
