對于微信紅包我相信今年過年時各位朋友都有知道吧,這個微信紅包相當的火爆了,下面我們來給各位介紹一個PHP版微信紅包API接口程序了,我們可以基于這個接口也實現開發第三方紅包功能.

根據微信高級紅包接口,開發PHP版本的API接口,現在進行主要代碼分析,紅包接口調用請求代碼,所有請求參數為必填參數與文檔對應:

class Wxapi {

    private $app_id = 'wxXXXXXXXXXXXX'; //公眾賬號appid，首先申請與之配套的公眾賬號

    private $app_secret = 'XXXXXXXXXXXXXXXXXXXXXXXX';//公眾號secret，用戶獲取用戶授權token

    private $app_mchid = 'XXXXXXXX';//商戶號id

    function __construct(){

    //do sth here....

    }

    /**

     * 微信支付

     * @param string $openid 用戶openid

     */

    public function pay($re_openid)

    {

        include_once('WxHongBaoHelper.php');

        $commonUtil = new CommonUtil();

        $wxHongBaoHelper = new WxHongBaoHelper();

        $wxHongBaoHelper->setParameter("nonce_str", $this->great_rand());//隨機字符串，丌長于 32 位

        $wxHongBaoHelper->setParameter("mch_billno", $this->app_mchid.date('YmdHis').rand(1000, 9999));//訂單號

        $wxHongBaoHelper->setParameter("mch_id", $this->app_mchid);//商戶號

        $wxHongBaoHelper->setParameter("wxappid", $this->app_id);

        $wxHongBaoHelper->setParameter("nick_name", '紅包');//提供方名稱

        $wxHongBaoHelper->setParameter("send_name", '紅包');//紅包發送者名稱

        $wxHongBaoHelper->setParameter("re_openid", $re_openid);//相對于醫脈互通的openid

        $wxHongBaoHelper->setParameter("total_amount", 100);//付款金額，單位分

        $wxHongBaoHelper->setParameter("min_value", 100);//最小紅包金額，單位分

        $wxHongBaoHelper->setParameter("max_value", 100);//最大紅包金額，單位分

        $wxHongBaoHelper->setParameter("total_num", 1);//紅包?Х拋莧聳?br />         $wxHongBaoHelper->setParameter("wishing", '感謝您參與紅包派發活動，祝您新年快樂！');//紅包祝福詫

        $wxHongBaoHelper->setParameter("client_ip", '127.0.0.1');//調用接口的機器 Ip 地址

        $wxHongBaoHelper->setParameter("act_name", '紅包活動');//活勱名稱

        $wxHongBaoHelper->setParameter("remark", '快來搶！');//備注信息

        $postXml = $wxHongBaoHelper->create_hongbao_xml();

        $url = 'https://api.mch.weixin.qq.com/mmpaymkttransfers/sendredpack';

        $responseXml = $wxHongBaoHelper->curl_post_ssl($url, $postXml);

        //用作結果調試輸出

        //echo htmlentities($responseXml,ENT_COMPAT,'UTF-8');

    $responseObj = simplexml_load_string($responseXml, 'SimpleXMLElement', LIBXML_NOCDATA);

    return $responseObj->return_code;

    }  //Vevb.com

獲取隨機字符串方法：

/**

* 生成隨機數

*/

public function great_rand(){

    $str = '1234567890abcdefghijklmnopqrstuvwxyz';

    for($i=0;$i<30;$i++){

        $j=rand(0,35);

        $t1 .= $str[$j];

    }

    return $t1;

}

簽名算法:

/**

例如：

appid：    wxd111665abv58f4f

mch_id：    10000100

device_info：  1000

Body：    test

nonce_str：  ibuaiVcKdpRxkhJA

第一步:對參數按照 key=value 的格式,并按照參數名 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:拼接支付密鑰:

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("密鑰不能為空！" . "<br>");

        }

        if($this->check_sign_parameters() == false) {   //檢查生成簽名參數

           throw new SDKRuntimeException("生成簽名參數缺失！" . "<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請求以及發送證書:

function curl_post_ssl($url, $vars, $second=30,$aHeader=array())

{

    $ch = curl_init();

    //超時時間

    curl_setopt($ch,CURLOPT_TIMEOUT,$second);

    curl_setopt($ch,CURLOPT_RETURNTRANSFER, 1);

    //這里設置代理，如果有的話

    curl_setopt($ch,CURLOPT_URL,$url);

    curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,false);

    curl_setopt($ch,CURLOPT_SSL_VERIFYHOST,false);

    //cert 與 key 分別屬于兩個.pem文件

    //請確保您的libcurl版本是否支持雙向認證，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";

//獲取用戶信息

$get = $_GET['param'];

$code = $_GET['code'];

//判斷code是否存在

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

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

    $param['code'] = $code;

    $packet = new Packet();

    //獲取用戶openid信息

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

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

        exit("NOAUTH");

    }

    //調取支付方法

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

}else{

    $packet->_route('userinfo');

}
