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:$error\n";
31 curl_close($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 }
