都已經做兩遍公眾號了，還是有時候總卡殼，今天把所有的問題都遇到的差不多了，咱就好好的總結總結
先說支付問題
申請下來公眾號后，先將后台該填的都填寫好
需要用到的公眾號信息
下面就開始要進入代碼狀態了
先說支付：
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; }

微信回調的方法：

微信回調方法處理方法 需放在function.php里
這兩個方法是處理微信給返回的一個支付成功的數據，這些數據都生成了一個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 ); }
微信回調，我自己設置指定的那個單獨創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(){ /* 讀取站點配置 */
$config = api('Config/lists'); C($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); //要求結果為字符串且輸出到屏幕上
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); //不驗證證書
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false); //不驗證證書
$res = curl_exec($ch); curl_close($ch);
//上面都是固定死的，下面才開始寫你要修改的數據 if(quzhi('trade_state',$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();//沒有找到這條數據就去執行下面的添加
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('支付異常'); }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); } } } } } }
好像支付就這些啦，如果有沒說的地方可以聯系我QQ:507285474

我們接着說退款：
點擊退款傳過來值，處理一下
最主要的是這個 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();//退款需要用的商品總價 // $gwc_tui_id = M('yy_goumai')->where(array('id'=>I('id')))->find();//退款需要用的商品單價(不是加上郵費的后的總金額) // dump($gwc_tui_id);die();
$suijishu = time().rand(111111111,999999999).$gm['danhao'];//退款需要用的隨機數 //1.退款商品的單價(不是加上郵費的后的總金額)，2.支付成功后生成的流水單號，3.微信支付平台上要顯示的流水號，(用時間戳 + 隨機數 + 用戶id);4.總價格。
$tuikuan = wx_tuikuan($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('退款失敗'); } } }else{ $this->error('出錯啦！訂單號參數值不對！'); } }
function.php 里的 wx_tuikaun()方法
/** * 微信退款 * @param $od_money 退款金額 * @param $od_id 訂單編號 * @return SimpleXMLElement */
function wx_tuikuan( $od_money, $od_id, $back_id, $zhifu ) { $pay = array( 'appid' => C( 'WX_APPID' ),
'mch_id' => C( 'WX_MCHID' ),

'out_refund_no' => $back_id,
'transaction_id' => $od_id,

/** * 微信退款 * @param $od_money 退款金額 * @param $od_id 訂單編號 * @return SimpleXMLElement */
function wx_refund($od_money, $od_id, $back_id) { $pay = array( 'appid' => C('WX_APPID'),
'mch_id' => C('WX_MCHID'),
'nonce_str' => getRandom(32),

然后好像沒有了！！！！
再見！！！
