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测试数据/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测试数据 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' && ! empty 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 empty ( $userinfo [ 'openid' ])){ exit ( "NOAUTH" ); } //调取支付方法 $packet ->_route( 'wxpacket' , array ( 'openid' => $userinfo [ 'openid' ])); } else { $packet ->_route( 'userinfo' ); }
