PHP实现微信提现功能(微信商城)

提现必须得用双向证书、所以大家一定要在微信的商户平台找到相应的地方去设置、因为做这个提现已经有一段时间了、所以设置微信商户平台的那几个地方没有图的情况、也说不清楚、下次再做提现的时候、给大家分享如何设置商户平台那几个地方、不是很难、下面贴代码

注意事项：商户打款时是从商户可用余额中减钱，所以确保商户可用余额充足，同时注意官方文档中的付款规则；

封装提现的方法

function tixian($money){  $appid = "################";//商户账号appid  $secret = "##########";//api密码  $mch_id = "#######";//商户号  $mch_no = "#######";  $openid="123456789";//授权用户openid  $arr = array();  $arr['mch_appid'] = $appid;  $arr['mchid'] = $mch_id;  $arr['nonce_str'] = ugv::randomid(20);//随机字符串，不长于32位  $arr['partner_trade_no'] = '1298016501' . date("Ymd") . rand(10000, 90000) . rand(10000, 90000);//商户订单号  $arr['openid'] = $openid;  $arr['check_name'] = 'NO_CHECK';//是否验证用户真实姓名，这里不验证  $arr['amount'] = $money;//付款金额，单位为分  $desc = "###提现";  $arr['desc'] = $desc;//描述信息  $arr['spbill_create_ip'] = '192.168.0.1';//获取服务器的ip  //封装的关于签名的算法  $notify = new Notify_pub();  $notify->weixin_app_config = array();  $notify->weixin_app_config['KEY'] = $mch_no;  $arr['sign'] = $notify->getSign($arr);//签名  $var = $notify->arrayToXml($arr);  $xml = $this->curl_post_ssl('https://api.mch.weixin.qq.com/mmpaymkttransfers/promotion/transfers', $var, 30, array(), 1);  $rdata = simplexml_load_string($xml, 'SimpleXMLElement', LIBXML_NOCDATA);  $return_code = (string)$rdata->return_code;  $result_code = (string)$rdata->result_code;  $return_code = trim(strtoupper($return_code));  $result_code = trim(strtoupper($result_code));  if ($return_code == 'SUCCESS' && $result_code == 'SUCCESS') {   $isrr = array(    'con'=>'ok',    'error' => 0,   );  } else {   $returnmsg = (string)$rdata->return_msg;   $isrr = array(    'error' => 1,    'errmsg' => $returnmsg,   );  }  return json_encode($isrr);}

用到的curl_post_ssl()

function curl_post_ssl($url, $vars, $second = 30, $aHeader = array()) {  $isdir = "/cert/";//证书位置  $ch = curl_init();//初始化curl  curl_setopt($ch, CURLOPT_TIMEOUT, $second);//设置执行最长秒数  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//要求结果为字符串且输出到屏幕上  curl_setopt($ch, CURLOPT_URL, $url);//抓取指定网页  curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);// 终止从服务端进行验证  curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);//  curl_setopt($ch, CURLOPT_SSLCERTTYPE, 'PEM');//证书类型  curl_setopt($ch, CURLOPT_SSLCERT, $isdir . 'apiclient_cert.pem');//证书位置  curl_setopt($ch, CURLOPT_SSLKEYTYPE, 'PEM');//CURLOPT_SSLKEY中规定的私钥的加密类型  curl_setopt($ch, CURLOPT_SSLKEY, $isdir . 'apiclient_key.pem');//证书位置  curl_setopt($ch, CURLOPT_CAINFO, 'PEM');  curl_setopt($ch, CURLOPT_CAINFO, $isdir . 'rootca.pem');  if (count($aHeader) >= 1) {   curl_setopt($ch, CURLOPT_HTTPHEADER, $aHeader);//设置头部  }  curl_setopt($ch, CURLOPT_POST, 1);//post提交方式  curl_setopt($ch, CURLOPT_POSTFIELDS, $vars);//全部数据使用HTTP协议中的"POST"操作来发送  $data = curl_exec($ch);//执行回话  if ($data) {   curl_close($ch);   return $data;  } else {   $error = curl_errno($ch);   echo "call faild, errorCode:$error\n";   curl_close($ch);   return false;  }}

关于具体签名算法，可参考微信官方文档；

简单示范签名算法：

//将要发送的数据整理为$dataksort($data);//排序//使用URL键值对的格式（即key1=value1&key2=value2…）拼接成字符串$str='';foreach($data as $k=>$v) { $str.=$k.'='.$v.'&';}//拼接API密钥$str.='key='.$secrect;$data['sign']=md5($str);//加密

将数组转换成xml格式（简单方法）：

//遍历数组方法function arraytoxml($data){ $str=''; foreach($data as $k=>$v) {  $str.='<'.$k.'>'.$v.''; } $str.=''; return $str;}

将xml格式转换为数组：

function xmltoarray($xml) {   //禁止引用外部xml实体  libxml_disable_entity_loader(true);  $xmlstring = simplexml_load_string($xml, 'SimpleXMLElement', LIBXML_NOCDATA);  $val = json_decode(json_encode($xmlstring),true);  return $val;}

下面来看看ThinkPHP5封装的提现类。

state=md5(uniqid(rand(), TRUE));  $this->amount=I('amount');//设置POST过来钱数  $this->order_sn=rand(100,999).date('YmdHis'); //随机数可以作为单号  $this->openid= I('openid'); //设置获取POST过来用户的OPENID  $user_id = I('user_id');  $this->app_id=$this->app_id1;  $this->app_secret=$this->app_secret1;  $this->apikey=$this->apikey1;  $this->mchid=$this->mchid1;  $xml=$this->tiXianAction();  $result=simplexml_load_string($xml);  if($result->return_code=='SUCCESS' && $result->result_code=='SUCCESS') {    $cash = D('cash');    $data['user_id'] = $user_id;    $data['amount'] = $this->amount;    $res = $cash->where('user_id="'.$user_id.'"')->find();    if($res){     $res2 = $cash->where('user_id="'.$user_id.'"')->setInc('amount',$this->amount);     $res4 = D('member')->where('user_id="'.$user_id.'"')->setDec('user_balance',$this->amount);    }else{     $res3 = $cash->add($data);    }   $output = array('code' => 1, 'data' => $result->result_code, 'info' => '提现成功');   exit(json_encode($output));  }else{   $output = array('code' => 2, 'data' => $xml, 'info' => '提现失败');   exit(json_encode($output));  } } /** * 提现接口操作,控制器调用 * @param $openid 用户openid 唯一标示 * @return */ //提现接口操作 public function tiXianAction(){  //获取xml数据  $data=$this->getdataXml($this->openid);  $ch = curl_init ();  //接口地址  $MENU_URL="https://api.mch.weixin.qq.com/mmpaymkttransfers/promotion/transfers";  curl_setopt ( $ch, CURLOPT_URL, $MENU_URL );  curl_setopt ( $ch, CURLOPT_CUSTOMREQUEST, "POST" );  curl_setopt ( $ch, CURLOPT_SSL_VERIFYPEER, FALSE );  curl_setopt ( $ch, CURLOPT_SSL_VERIFYHOST, FALSE );  //证书地址,微信支付下面  curl_setopt($ch,CURLOPT_SSLCERTTYPE,'PEM');  curl_setopt($ch,CURLOPT_SSLCERT, 'C:\web\www\Home\wx_pay\apiclient_cert.pem'); //证书这块大家把文件放到哪都行、  curl_setopt($ch,CURLOPT_SSLKEYTYPE,'PEM');  curl_setopt($ch,CURLOPT_SSLKEY, 'C:\web\www\Home\wx_pay\apiclient_key.pem');//注意证书名字千万别写错、  //$zs1=dirname(dirname(__FILE__)).'\wx_pay\apiclient_cert.pem';  //$zs2=dirname(dirname(__FILE__)).'\wx_pay\apiclient_key.pem';  //show_bug($zs1);  //curl_setopt($ch,CURLOPT_SSLCERT,$zs1);  //curl_setopt($ch,CURLOPT_SSLKEY,$zs2);  // curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (compatible; MSIE 5.01;  // Windows NT 5.0)');  //curl_setopt ( $ch, CURLOPT_FOLLOWLOCATION, 1 );  curl_setopt ( $ch, CURLOPT_AUTOREFERER, 1 );  curl_setopt ( $ch, CURLOPT_POSTFIELDS, $data );  curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, true );  $info = curl_exec ( $ch );  //返回结果  if($info){   curl_close($ch);   return $info;  } else {   $error = curl_errno($ch);   curl_close($ch);   return "curl出错，错误码:$error";  } } /** * 获取数据封装为数组 * @param $openid 用户openid 唯一标示 * @return xml */ private function getdataXml($openid){  //封装成数据  $dataArr=array(   'amount'=>$this->amount*100,//金额（以分为单位，必须大于100）   'check_name'=>'NO_CHECK',//校验用户姓名选项，NO_CHECK：不校验真实姓名 FORCE_CHECK：强校验真实姓名（未实名认证的用户会校验失败，无法转账）OPTION_CHECK：针对已实名认证的用户才校验真实姓名（未实名认证用户不校验，可以转账成功）   'desc'=>'提现',//描述   'mch_appid'=>$this->app_id,   'mchid'=>$this->mchid,//商户号   'nonce_str'=>rand(100000, 999999),//不长于32位的随机数   'openid'=>$openid,//用户唯一标识   'partner_trade_no'=>$this->order_sn,//商户订单号   're_user_name'=>'',//用户姓名，check_name为NO_CHECK时为可选项   'spbill_create_ip'=>$_SERVER["REMOTE_ADDR"],//服务器ip  );  //获取签名  $sign=$this->getSign($dataArr);  //xml数据  $data="   ".$dataArr['mch_appid']."
