PHP实现微信提现功能

Posted 2020-11-22 Raylove

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

 1 function tixian($money){
 2     $appid = "################";//商户账号appid
 3     $secret = "##########";//api密码
 4     $mch_id = "#######";//商户号
 5     $mch_no = "#######";
 6     $openid="123456789";//授权用户openid
 7 
 8     $arr = array();
 9     $arr[‘mch_appid‘] = $appid;
10     $arr[‘mchid‘] = $mch_id;
11     $arr[‘nonce_str‘] = ugv::randomid(20);//随机字符串，不长于32位
12     $arr[‘partner_trade_no‘] = ‘1298016501‘ . date("Ymd") . rand(10000, 90000) . rand(10000, 90000);//商户订单号
13     $arr[‘openid‘] = $openid;
14     $arr[‘check_name‘] = ‘NO_CHECK‘;//是否验证用户真实姓名，这里不验证
15     $arr[‘amount‘] = $money;//付款金额，单位为分
16     $desc = "###提现";
17     $arr[‘desc‘] = $desc;//描述信息
18     $arr[‘spbill_create_ip‘] = ‘192.168.0.1‘;//获取服务器的ip
19     //封装的关于签名的算法
20     $notify = new Notify_pub();
21     $notify->weixin_app_config = array();
22     $notify->weixin_app_config[‘KEY‘] = $mch_no;
23 
24     $arr[‘sign‘] = $notify->getSign($arr);//签名
25 
26     $var = $notify->arrayToXml($arr);
27     $xml = $this->curl_post_ssl(‘https://api.mch.weixin.qq.com/mmpaymkttransfers/promotion/transfers‘, $var, 30, array(), 1);
28     $rdata = simplexml_load_string($xml, ‘SimpleXMLElement‘, LIBXML_NOCDATA);
29     $return_code = (string)$rdata->return_code;
30     $result_code = (string)$rdata->result_code;
31     $return_code = trim(strtoupper($return_code));
32     $result_code = trim(strtoupper($result_code));
33 
34     if ($return_code == ‘SUCCESS‘ && $result_code == ‘SUCCESS‘) {
35       $isrr = array(
36         ‘con‘=>‘ok‘,
37         ‘error‘ => 0,
38       );
39     } else {
40       $returnmsg = (string)$rdata->return_msg;
41       $isrr = array(
42         ‘error‘ => 1,
43         ‘errmsg‘ => $returnmsg,
44       );
45 
46     }
47     return json_encode($isrr);
48 } 

 

 

用到的curl_post_ssl()

 1 function curl_post_ssl($url, $vars, $second = 30, $aHeader = array())
 2   {
 3     $isdir = "/cert/";//证书位置
 4 
 5     $ch = curl_init();//初始化curl
 6 
 7     curl_setopt($ch, CURLOPT_TIMEOUT, $second);//设置执行最长秒数
 8     curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//要求结果为字符串且输出到屏幕上
 9     curl_setopt($ch, CURLOPT_URL, $url);//抓取指定网页
10     curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);// 终止从服务端进行验证
11     curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);//
12     curl_setopt($ch, CURLOPT_SSLCERTTYPE, ‘PEM‘);//证书类型
13     curl_setopt($ch, CURLOPT_SSLCERT, $isdir . ‘apiclient_cert.pem‘);//证书位置
14     curl_setopt($ch, CURLOPT_SSLKEYTYPE, ‘PEM‘);//CURLOPT_SSLKEY中规定的私钥的加密类型
15     curl_setopt($ch, CURLOPT_SSLKEY, $isdir . ‘apiclient_key.pem‘);//证书位置
16     curl_setopt($ch, CURLOPT_CAINFO, ‘PEM‘);
17     curl_setopt($ch, CURLOPT_CAINFO, $isdir . ‘rootca.pem‘);
18     if (count($aHeader) >= 1) {
19       curl_setopt($ch, CURLOPT_HTTPHEADER, $aHeader);//设置头部
20     }
21     curl_setopt($ch, CURLOPT_POST, 1);//post提交方式
22     curl_setopt($ch, CURLOPT_POSTFIELDS, $vars);//全部数据使用HTTP协议中的"POST"操作来发送
23 
24     $data = curl_exec($ch);//执行回话
25     if ($data) {
26       curl_close($ch);
27       return $data;
28     } else {
29       $error = curl_errno($ch);
30       echo "call faild, errorCode:$error
";
31       curl_close($ch);
32       return false;
33     }
34 }

 

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：

 1 //将要发送的数据整理为$data
 2 
 3 ksort($data);//排序
 4 //使用URL键值对的格式（即key1=value1&key2=value2…）拼接成字符串
 5 $str=‘‘;
 6 foreach($data as $k=>$v) {
 7   $str.=$k.‘=‘.$v.‘&‘;
 8 }
 9 //拼接API密钥
10 $str.=‘key=‘.$secrect;
11 $data[‘sign‘]=md5($str);//加密

 

 

将数组转换成xml格式（简单方法）：

1 //遍历数组方法
2 function arraytoxml($data){
3   $str=‘<xml>‘;
4   foreach($data as $k=>$v) {
5     $str.=‘<‘.$k.‘>‘.$v.‘</‘.$k.‘>‘;
6   }
7   $str.=‘</xml>‘;
8   return $str;
9 }

 

 

将xml格式转换为数组：

1 function xmltoarray($xml) { 
2    //禁止引用外部xml实体 
3   libxml_disable_entity_loader(true); 
4   $xmlstring = simplexml_load_string($xml, ‘SimpleXMLElement‘, LIBXML_NOCDATA); 
5   $val = json_decode(json_encode($xmlstring),true); 
6   return $val;
7 }
8  

 

 

下面来看看Thinkphp5封装的提现类。

  1 <?php
  2 namespace HomeController;
  3 use ThinkController;
  4 class TixianController extends Controller{
  5 
  6   //高级功能-》开发者模式-》获取
  7   private $app_id1 = ‘‘;   //appid
  8   private $app_secret1 = ‘‘; //secreat
  9   private $apikey1 = ‘‘; //支付秘钥
 10   private $mchid1 = ‘s‘;    //商户号
 11 
 12     private $app_id=null;
 13     private $app_secret=null;
 14     private $apikey=null;
 15     private $mchid=null;
 16 
 17 
 18   public $error=0;
 19   public $state = ‘‘;
 20   //金额,需在实例化时传入
 21   public $amount = ‘0‘;
 22   //用户订单号,需在实例化时传入
 23   public $order_sn = ‘‘;
