都已经做两遍公众号了，还是有时候总卡壳，今天把所有的问题都遇到的差不多了，咱就好好的总结总结
先说支付问题
申请下来公众号后，先将后台该填的都填写好
需要用到的公众号信息
下面就开始要进入代码状态了
先说支付：
需要放在function.php 里的方法
吊起微信支付最重要的方法（一）
/** * 直接生成微信jssdk_config * @echo string $jssdk Jssdk_config * @author 5heAtMin9 <sheatming@foxmail.com> */
function wx_jssdk_config($debug='true'){ $getSignPackage = wx_getSignPackage(); $jssdk = '<script src="https://res.wx.qq.com/open/js/jweixin-1.0.0.js"></script>'; $jssdk .= '<script> wx.config({ debug: '.$debug.', appId: "'.$getSignPackage['appId'].'", timestamp: "'.$getSignPackage['timestamp'].'", nonceStr: "'.$getSignPackage['nonceStr'].'", signature: "'.$getSignPackage['signature'].'", jsApiList: ["checkJsApi","onMenuShareTimeline","onMenuShareAppMessage","onMenuShareQQ", "onMenuShareWeibo","onMenuShareQZone","hideMenuItems","showMenuItems","hideAllNonBaseMenuItem","showAllNonBaseMenuItem","translateVoice","startRecord","stopRecord","onVoiceRecordEnd","playVoice","onVoicePlayEnd","pauseVoice","stopVoice","uploadVoice","downloadVoice","chooseImage","previewImage","uploadImage","downloadImage","getNetworkType","openLocation","getLocation","hideOptionMenu","showOptionMenu","closeWindow","scanQRCode","chooseWXPay","openProductSpecificView","addCard","chooseCard","openCard"], }); </script>'; echo $jssdk; }
吊起微信支付最重要的方法（二）

function wx_h5_pay($openid, $url, $od_title, $od_money, $od_id) { if(is_null($url) || $url == ''){ $url = 'http://'. $_SERVER['HTTP_HOST'].'/weixinpay/notify_url.php'; } $pay = array( 'appid' => C('WX_APPID'),
'mch_id' => C('WX_MCHID'),
'nonce_str' => getRandom(32),
'body' => $od_title,
'out_trade_no' => $od_id,
'total_fee' => $od_money * 100,
'spbill_create_ip' => get_client_ip(),
'notify_url' => $url,//通知地址
'trade_type' => 'JSAPI',
'openid' => $openid, ); ksort($pay); $string = ToUrlParams($pay).'&key='.C('WX_PAYAPIKEY'); $string = md5($string); $string = strtoupper($string); $pay['sign'] = $string; $postObj = simplexml_load_string(os_post('https://api.mch.weixin.qq.com/pay/unifiedorder', arrayToXml($pay)), 'SimpleXMLElement', LIBXML_NOCDATA); $time = time(); $timeStamp = "$time"; $nonceStr = getRandom(32); $data['package'] = 'prepay_id='.$postObj -> prepay_id; $data['timestamp'] = $timeStamp; $data['nonceStr'] = $nonceStr; $val = 'appId='.C('WX_APPID').'&'; $val .='nonceStr='.$nonceStr.'&'; $val .='package='.$data['package'].'&'; $val .='signType=MD5&'; $val .='timeStamp='.$timeStamp; $stringA = $val.'&key='.C('WX_PAYAPIKEY'); $data['sign'] = strtoupper(MD5($stringA)); $data['val'] = $val; return $data; }
微信回调的方法：
<?php /** * Created by PhpStorm. * User: Kuoer * Date: 2016/4/9 * Time: 14:41 */
function payok($orderid, $alipayid, $openid, $total_fee, $type) { $postUrl = 'http://'.$_SERVER['HTTP_HOST'].'/index.php?s=/Home/Pay/weixinpay'; $curlPost = 'orderid=' . $orderid . '&alipayid=' . $alipayid . '&openid=' . $openid; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $postUrl); //抓取指定网页
curl_setopt($ch, CURLOPT_HEADER, 0); //设置header
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0); //要求结果为字符串且输出到屏幕上
curl_setopt($ch, CURLOPT_POST, 1); //post提交方式
curl_setopt($ch, CURLOPT_POSTFIELDS, $curlPost); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); // 终止从服务端进行验证
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE); curl_exec($ch); //运行curl
curl_close($ch); } header('Access-Control-Allow-Origin: *'); header('Access-Control-Allow-Headers: X-Requested-With'); $xml = file_get_contents("php://input"); $xml = simplexml_load_string($xml); //return (string)$xml->prepay_id;
$success = (string)$xml->return_code; if ($success == 'SUCCESS') { $out_trade_no = (string)$xml->out_trade_no; $trade_no = (string)$xml->transaction_id; $openid = (string)$xml->openid; $pay = (string)$xml->total_fee; echo payok($out_trade_no, $trade_no, $openid, $pay, 'weixin'); } else { $return_code = (string)$xml->return_code; $return_msg = (string)$xml->return_msg; echo '<xml> <return_code><![CDATA[' . $return_code . ']]></return_code> <return_msg><![CDATA[' . $return_msg . ']]></return_msg> </xml>'; }
微信回调方法处理方法 需放在function.php里
这两个方法是处理微信给返回的一个支付成功的数据，这些数据都生成了一个txt文件
function quzhi( $s, $xml ) { $str = explode( '<' . $s . '>', $xml ); $str = explode( '</' . $s . '>', $str[ 1 ] ); return guolv( trim( $str[ 0 ] ) ); } function guolv( $str ) { $s = array( '!', '-', '[', 'CDATA', ']', '<', '>' ); return str_replace( $s, '', $str ); }
微信回调，我自己设置指定的那个单独创建的控制器里的方法：
<?php namespace Home\Controller; use Think\Controller; use User\Api\UserApi; class PayController extends HomeController { protected function _initialize(){ /* 读取站点配置 */
$config = api('Config/lists'); C($config); //添加配置
} public function weixinpay(){ $orderid = I('orderid'); $suijishu = rand(100000000,99999999999); $val = 'appid='.C('WX_APPID').'&'; $val .='mch_id='.C('WX_MCHID').'&'; $val .='nonce_str='.$suijishu.'&'; $val .='out_trade_no='.$orderid; $stringA = $val.'&key='.C('WX_PAYAPIKEY'); $url = 'https://api.mch.weixin.qq.com/pay/orderquery'; $post_data = '<xml> <appid>'.C('WX_APPID').'</appid> <mch_id>'.C('WX_MCHID').'</mch_id> <nonce_str>'.$suijishu.'</nonce_str> <out_trade_no>'.$orderid.'</out_trade_no> <sign>'.strtoupper(MD5($stringA)).'</sign> </xml>'; $ch = curl_init(); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_HEADER, false); curl_setopt($ch, CURLOPT_URL,$url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); //要求结果为字符串且输出到屏幕上
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); //不验证证书
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false); //不验证证书
$res = curl_exec($ch); curl_close($ch);
//上面都是固定死的，下面才开始写你要修改的数据 if(quzhi('trade_state',$res) == 'SUCCESS'){ $orderid = I('orderid'); $data['gwc_danhao'] = I('orderid'); $data['money'] = quzhi('total_fee',$res); $data['liushui_hao'] = quzhi('transaction_id',$res); $on = M('yy_pay')->where($data)->find();//没有找到这条数据就去执行下面的添加
if(!$on){ $gwc_id['danhao'] = I('orderid'); $gwc_uid = M('yy_goumai')->where($gwc_id)->getField('uid'); $data['uid'] = $gwc_uid; $data['time'] = time(); M('yy_pay')->add($data); $price = M('yy_goumai')->where($gwc_id)->sum('zongjia'); if($price*100 != $data['money']){ $this->error('支付异常'); }else{ $gouwuche = M('yy_goumai')->where($gwc_id)->select(); foreach($gouwuche as $k=>$v){ $gwc_zt['utime']=time(); $gwc_zt['state']=1; M('yy_goumai')->where(array('id'=>$v['id']))->setField($gwc_zt); } } } } } }
好像支付就这些啦，如果有没说的地方可以联系我QQ:507285474

我们接着说退款：
点击退款传过来值，处理一下
最主要的是这个 function.php里的wx_tuikaun()方法
public function tuikuan(){ $wher['id'] =I('id'); $data['gwc_danhao'] = M('yy_goumai')->where($wher)->getField('danhao'); $re = M('yy_pay')->where($data)->find(); if($re){ $gwc_arr['danbao'] = $re['gwc_danhao']; $gm = M('yy_goumai')->where($gwc_arr)->find();//退款需要用的商品总价 // $gwc_tui_id = M('yy_goumai')->where(array('id'=>I('id')))->find();//退款需要用的商品单价(不是加上邮费的后的总金额) // dump($gwc_tui_id);die();
$suijishu = time().rand(111111111,999999999).$gm['danhao'];//退款需要用的随机数 //1.退款商品的单价(不是加上邮费的后的总金额)，2.支付成功后生成的流水单号，3.微信支付平台上要显示的流水号，(用时间戳 + 随机数 + 用户id);4.总价格。
$tuikuan = wx_tuikuan($gm['danjia'],$re['liushui_hao'],$suijishu,$gm['zongjia']); if($tuikuan -> result_code == 'SUCCESS'){ M('yy_pay')->where($data)->setField('tuikuan','1'); $gwc_zt['state'] = '-2'; $gwc_zt['utime'] = time(); $yes = M('yy_goumai')->where($wher)->setField($gwc_zt); if($yes){ $this->success('退款成功'); }else{ $this->error('退款失败'); } } }else{ $this->error('出错啦！订单号参数值不对！'); } }
function.php 里的 wx_tuikaun()方法
/** * 微信退款 * @param $od_money 退款金额 * @param $od_id 订单编号 * @return SimpleXMLElement */
function wx_tuikuan( $od_money, $od_id, $back_id, $zhifu ) { $pay = array( 'appid' => C( 'WX_APPID' ),
'mch_id' => C( 'WX_MCHID' ),

$postObj = simplexml_load_string( $tmp, 'SimpleXMLElement', LIBXML_NOCDATA ); return $postObj; }
/** * 微信退款 * @param $od_money 退款金额 * @param $od_id 订单编号 * @return SimpleXMLElement */
function wx_refund($od_money, $od_id, $back_id) { $pay = array( 'appid' => C('WX_APPID'),
'mch_id' => C('WX_MCHID'),
'nonce_str' => getRandom(32),
'op_user_id' => C('WX_MCHID'),
'out_refund_no' => $back_id,
'out_trade_no' => $od_id,
'refund_fee' => $od_money * 100,

然后好像没有了！！！！
再见！！！
