fastadmin支付插件中使用v3支付的方法

admin · 发表于 2026-5-21 14:31:51

当前微信支付宝整合插件中微信支付v3配置仍需要配置v2证书，否则v3支付失败，这可能是个bug，等官方后续更新。

v3微信支付需要配置的参数包括：

我们在需要调用V3支付的地方执行：

set_addon_config('epay', ['version'=>'v3'], false);

复制代码

将支付版本改为使用V3。
1、需要使用到的支付类：

use addons\epay\library\Service;
use Yansongda\Pay\Exceptions\BusinessException;
use Yansongda\Pay\Exceptions\GatewayException;
use Yansongda\Pay\Exceptions\InvalidSignException;
use addons\epay\library\Collection;
use GuzzleHttp\Psr7\Response;

复制代码

2、构造支付参数发起支付：

// 支付参数
$pay_params = [
'amount' => $order->payfee,
'orderid' => $order->ordersn,
'type' => 'wechat',
'title' => '商城购买商品消费',
'returnurl' => null,
'method' => 'miniapp',
'openid' => $third->openid
];
// 回调通知地址
$pay_params['notifyurl'] = $this->request->root(true) . "/addons/eshop/api.goods/notify";
\think\Log::record($pay_params);
// 调用支付
try {
$response = Service::submitOrder($pay_params);
\think\Log::record($response);
$this->success('请求成功', $response);
} catch (BusinessException|GatewayException|InvalidSignException|Collection $e) {
\think\Log::record($e);
$this->error($e->getMessage());
}

复制代码

3、支付回调通知：

public function notify()
{
$params = $this->request->param();
\think\Log::record($params);
$pay = Service::checkNotify('wechat');
if (!$pay) {
echo '签名错误';
return;
}
\think\Log::record(Service::isVersionV3());
$data = Service::isVersionV3() ? $pay->callback() : $pay->verify();
\think\Log::record($data);
$notifydata = json_decode($data, true);
try {
// 订单表单
$orderdata = [
'paytype' => 2,
'paytime' => time(),
'status' => 1
];
if (Service::isVersionV3()) {
$out_trade_no = $notifydata['resource']['ciphertext']['out_trade_no'];
$orderdata['transid'] = $notifydata['resource']['ciphertext']['transaction_id'];
$orderdata['cash'] = $notifydata['resource']['ciphertext']['amount']['payer_total'] / 100;
$orderdata['realpayfee'] = $notifydata['resource']['ciphertext']['amount']['payer_total'] / 100;
} else {
$out_trade_no = $data->out_trade_no;
$orderdata['cash'] = $data->total_fee / 100;
$orderdata['transid'] = $data->transaction_id;
$orderdata['realpayfee'] = $data->total_fee / 100;
}
// 查询订单
$order = Order::where(['ordersn'=>$out_trade_no])->find();
// 待付款的才可以执行
if ($order->status == 0) {
// 更新订单
$result = Order::update($orderdata, ['id'=>$order->id]);
if ($result) {
// 处理订单商品状态
$ordergoods = Ordergoods::where(['order_id'=>$order->id])->find();
if ($ordergoods) {
$ordergoods->allowField(true)->save(['status'=>1]);
}
// 积分兑换处理积分
if ($order->paystyle == 1) {
User::score(-$order->score, $order->user_id, '商城购买商品消费');
}
// 商品/规格信息
if ($ordergoods->option_id) {
// 规格
$option = Option::get($ordergoods->option_id);
if (!empty($option)) {
// 更新库存
$stock = $option->stock - $ordergoods->total;
$option->allowField(true)->save(['stock'=>$stock]);
}
} else {
// 商品
$goods = Goods::get($ordergoods->goods_id);
if (!empty($goods)) {
// 更新库存
$stock = $goods->stock - $ordergoods-total;
$goods->allowField(true)->save(['stock'=>$stock]);
}
}
}
}
} catch (Exception $e) {
$this->error($e->getMessage());
}
//下面这句必须要执行,且在此之前不能有任何输出
if (Service::isVersionV3()) {
return $pay->success()->getBody()->getContents();
} else {
return $pay->success()->send();
}
}

4、退款：

use Yansongda\Pay\Pay;
use addons\epay\library\Service;
use Yansongda\Pay\Exceptions\BusinessException;
use fast\Random;

复制代码

public function refund($ids = null)
{
$row = $this->model->get($ids);
if (!$row) {
$this->error(__('No Results were found'));
}
$adminIds = $this->getDataLimitAdminIds();
if (is_array($adminIds) && !in_array($row[$this->dataLimitField], $adminIds)) {
$this->error(__('You have no permission'));
}
if (false === $this->request->isPost()) {
$this->view->assign('row', $row);
return $this->view->fetch();
}
$params = $this->request->post('row/a');
if (empty($params)) {
$this->error(__('Parameter %s can not be empty', ''));
}
$params = $this->preExcludeFields($params);
// \think\Log::record($params);
if ($row->status < 1 || $row->status > 3) {
$this->error('当前订单状态不允许退款');
}
// 判断退款金额
if (bccomp($params['refundfee'], $row->realpayfee, 2) > 0) {
// \think\Log::record('退款金额不得高于支付金额');
$this->error('退款金额不得高于支付金额');
}
if (bccomp($params['refundfee'], '0.00', 2) <= 0) {
// \think\Log::record('退款金额不合法');
$this->error('退款金额不合法');
}
// 积分+现金支付
if ($row->paystyle == 1) {
if (bccomp($params['refundscore'], $row->score, 0) > 0) {
// \think\Log::record('退款金额不得高于支付金额');
$this->error('退款积分不得高于支付积分');
}
if (bccomp($params['refundscore'], '0', 0) <= 0) {
// \think\Log::record('退款金额不合法');
$this->error('退款积分不合法');
}
}
// 退款单号
$params['refundsn'] = 'T'.date('YmdHis').Random::numeric();
// 退款时间
$params['refundtime'] = time();
// 退款状态
$params['status'] = 5;
// 支付方式
if ($row->paytype == 1) {
// \think\Log::record($params);
// 余额支付
User::money($params['refundfee'], $row->user_id, '商城购物订单退款');
// 退回积分
if ($params['refundscore'] > 0) {
User::score($params['refundscore'], $row->user_id, '商城购物订单退款');
}
// 更新订单状态
$result = $row->allowField(true)->save($params);
// \think\Log::record($result);
if ($result) {
$this->success('退款成功');
}
$this->error('退款失败，请核实用户余额和积分记录');
} elseif ($row->paytype == 2) {
$result = false;
Db::startTrans();
// 退款参数
$order = [
'_action' => 'mini',
'out_trade_no' => $row->ordersn,
'out_refund_no' => $params['refundsn'],
'amount' => [
'refund' => $params['refundfee'] * 100,
'total' => $row->realpayfee * 100,
'currency' => 'CNY',
],
'reason' => $params['reason']
];
$config = Service::getConfig('wechat');
// \think\Log::record($config);
$result = false;
$erromsg = '退款成功';
// 微信支付
try {
// 调用支付接口
$ret = Pay::wechat($config)->refund($order);
\think\Log::record($ret);
$response = json_decode($ret, true);
\think\Log::record($response);
if ($response['status'] == 'SUCCESS' || $response['status'] == 'PROCESSING') {
// 支付平台退款单号
$params['refund_id'] = $response['refund_id'];
$result = $row->allowField(true)->save($params);
if ($result) {
// 退回积分
if ($params['refundscore'] > 0) {
User::score($params['refundscore'], $row->user_id, '商城购物订单退款');
}
Db::commit();
} else {
$erromsg = '退款成功，但订单状态更新失败，请核实用户积分记录！';
}
} else {
$erromsg = '退款失败，请稍后重试！';
}
} catch (Exception $e) {
Db::rollback();
$this->error($e->getMessage());
}
if (false === $result) {
$this->error($erromsg);
}
$this->success($erromsg);
}
}
