PHP实现微信提现功能
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 } 8
