微信公众号整套逻辑的支付和退款
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）
/**

* @echo string $jssdk Jssdk_config

*/
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>

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();

// $gwc_tui_id = M('yy_goumai')->where(array('id'=>I('id')))->find();//退款需要用的商品单价(不是加上邮费的后的总金额)
// dump($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
/**

*/
function wx_tuikuan( $od_money, $od_id, $back_id, $zhifu ) {

}
