PHP实现微信提现（企业付款到零钱）

怎么开通企业付款到零钱？

有的商户号的产品中心是没有这个功能的，不过，该功能的pid（product id）是5，只要随便进去某一个产品，在地址栏把pid改为5。

即可进入该功能页面，进行开通，不过要满足条件。

用户提现代码：

 1 //用户微信提现
 2 private function withdrawals_weixin($id){
 3 $falg = M(\'withdrawals\')->where([\'id\'=>$id])->find();
 4 $openid = M(\'users\')->where(\'user_id\', $falg[\'user_id\'])->value(\'openid\');
 5 $data[\'openid\'] = $openid;
 6 $data[\'pay_code\'] = $falg[\'id\'].$falg[\'user_id\'];
 7 $data[\'desc\'] = \'提现ID\'.$falg[\'id\'];
 8 if($falg[\'taxfee\'] >= $falg[\'money\']){
 9 return array(\'status\'=>1, \'msg\'=>"提现额度必须大于手续费！" );
10 }else{
11 $data[\'money\'] = bcsub($falg[\'money\'], $falg[\'taxfee\'], 2);
12 }
13 include_once PLUGIN_PATH . "payment/weixin/weixin.class.php";
14 $weixin_obj = new \weixin();
15 $result = $weixin_obj->transfer($data);
16 
17 return $result;
18 }

 

其中pay_code在商户号的提现功能是唯一的，所以为了防重放攻击，这个值千万不能用随机数，最好用ID，具有提现记录唯一。

提现逻辑代码：

 1 // 微信提现转账
 2 function transfer($data){
 3 
 4 header("Content-type: text/html; charset=utf-8");
 5 //CA证书及支付信息
 6 $wxchat[\'appid\'] = WxPayConfig::$appid;
 7 $wxchat[\'mchid\'] = WxPayConfig::$mchid;
 8 
 9 $wxchat[\'api_cert\'] = PLUGIN_PATH.\'/payment/weixin/cert/apiclient_cert.pem\';
10 $wxchat[\'api_key\'] = PLUGIN_PATH.\'/payment/weixin/cert/apiclient_key.pem\';
11 
12 // $wxchat[\'api_ca\'] = \'/plugins/payment/weixin/cert/rootca.pem\';
13 $webdata = array(
14 \'mch_appid\' => $wxchat[\'appid\'],
15 \'mchid\' => $wxchat[\'mchid\'],
16 \'nonce_str\' => md5(time()),
17 //\'device_info\' => \'1000\',
18 \'partner_trade_no\'=> $data[\'pay_code\'], //商户订单号，需要唯一
19 \'openid\' => $data[\'openid\'],//转账用户的openid
20 \'check_name\'=> \'NO_CHECK\', //OPTION_CHECK不强制校验真实姓名, FORCE_CHECK：强制 NO_CHECK：
21 //\'re_user_name\' => \'jorsh\', //收款人用户姓名
22 \'amount\' => $data[\'money\'] * 100, //付款金额单位为分
23 \'desc\' => $data[\'desc\'],
24 \'spbill_create_ip\' => request()->ip(),
25 );
26 
27 foreach ($webdata as $k => $v) {
28 $tarr[] =$k.\'=\'.$v;
29 }
30 
31 sort($tarr);
32 $sign = implode($tarr, \'&\');
33 $sign .= \'&key=\'.WxPayConfig::$key;
34 $webdata[\'sign\']=strtoupper(md5($sign));
35 
36 $wget = $this->array2xml($webdata);
37 
38 $pay_url = \'https://api.mch.weixin.qq.com/mmpaymkttransfers/promotion/transfers\';
39 
40 $res = $this->http_post($pay_url, $wget, $wxchat);
41 
42 if(!$res){
43 return array(\'status\'=>1, \'msg\'=>"Can\'t connect the server" );
44 }
45 $content = simplexml_load_string($res, \'SimpleXMLElement\', LIBXML_NOCDATA);
46 
47 if(strval($content->return_code) == \'FAIL\'){
48 return array(\'status\'=>1, \'msg\'=>strval($content->return_msg));
49 }
50 if(strval($content->result_code) == \'FAIL\'){
51 return array(\'status\'=>1, \'msg\'=>strval($content->err_code),\':\'.strval($content->err_code_des));
52 }
53 
54 $rdata = array(
55 \'mch_appid\' => strval($content->mch_appid),
56 \'mchid\' => strval($content->mchid),
57 \'device_info\' => strval($content->device_info),
58 \'nonce_str\' => strval($content->nonce_str),
59 \'result_code\' => strval($content->result_code),
60 \'partner_trade_no\' => strval($content->partner_trade_no),
61 \'payment_no\' => strval($content->payment_no),
62 \'payment_time\' => strval($content->payment_time),
63 );
64 return $rdata;

66 }

 

其中 PLUGIN_PATH 是一个常量

 1 define(\'PLUGIN_PATH\', __DIR__ . \'/plugins/\');
 2  定义插件目录
