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$data
ksort($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){
 $str='<xml>';
 foreach($data as $k=>$v) {
  $str.='<'.$k.'>'.$v.'</'.$k.'>';
 }
 $str.='</xml>';
 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。

  private $mchid=null;
 public $error=0;
 public $state = '';
 //金额,需在实例化时传入
