对于微信红包我相信今年过年时各位朋友都有知道吧,这个微信红包相当的火爆了,下面我们来给各位介绍一个PHP版微信红包API接口程序了,我们可以基于这个接口也实现开发第三方红包功能.

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?Х抛苋耸?br />         $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;

    }  //phpfensi.com

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_id=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($get=='access_token' && !emptyempty($code)){

    $param['param'] = 'access_token';

    $param['code'] = $code;

    $packet = new Packet();

    //获取用户openid信息

    $userinfo = $packet->_route('userinfo',$param);

    if(emptyempty($userinfo['openid'])){

        exit("NOAUTH");

    }

    //调取支付方法

    $packet->_route('wxpacket',array('openid'=>$userinfo['openid']));

}else{

    $packet->_route('userinfo');

}
