####  ldpay.php（跳转 + 签名）：

exit;
?>
```
#### ldpayapi.php（异步通知）

```
<?php

ob_clean();

// 获取异步通知参数
$pid = $_GET['pid'];

$mysign = md5($sign_str);

// 验证通过且支付成功
if ($sign == $mysign && $trade_status == 'TRADE_SUCCESS') {
    // 解析参数（玩家信息）
    $array = explode("_", $param);
    if (count($array) < 4) {
        echo "fail"; // 参数错误
        exit;
    }
    $serverKey = $array[1];
    $serverinfo = $qus[$serverKey];

    mysqli_close($conn);

// 一样的必须返回success

    exit;

// 验证失败

```
#### ldpayreturn.php（页面跳转通知）

```
<?php
require 'ldconfig.php';

// 获取参数
$pid = $_GET['pid'];
$trade_no = $_GET['trade_no'];
$out_trade_no = $_GET['out_trade_no'];
$type = $_GET['type'];
$name = $_GET['name'];
$money = $_GET['money'];
$trade_status = $_GET['trade_status'];
$param = $_GET['param'];
$sign = $_GET['sign'];

// 验证签名
$params = array(
    'pid' => $pid,
    'trade_no' => $trade_no,
    'out_trade_no' => $out_trade_no,
    'type' => $type,
    'name' => $name,
    'money' => $money,
    'trade_status' => $trade_status,
    'param' => $param
);
ksort($params);

// 生成签名
$sign_parts = array();
foreach ($params as $k => $v) {
    if ($v !== '' && $k != 'sign' && $k != 'sign_type') {
        $sign_parts[] = "{$k}={$v}";
    }
}
$sign_str = implode('&', $sign_parts) . $userkey;
$mysign = md5($sign_str);

// 通过
if ($sign == $mysign && $trade_status == 'TRADE_SUCCESS') {
    echo "<script>alert('支付成功！即将返回游戏。');window.location.href='../';</script>"; //替换为游戏首页，也可以使用 window.open() 脚本打开支付页面，然后用window.close()关闭标签页具体我放在下面。
} else {
    echo "<script>alert('支付失败，请重试！');history.back();</script>";
}
?>
```
### 修改支付打开方式：
将表单提交改为通过 window.open() 打开支付页，然后回调后关掉

```
<button type="button" class="plays_box_s3_bnt" onclick="openPayWindow()">立即支付</button>

// 拼接
    const payUrl = `ldpay.php?type=${type}&out_trade_no=${outTradeNo}&money=${money}&remark=${encodeURIComponent(remark)}&productId=${productId}&rolename=${encodeURIComponent(rolename)}&serverid=${serverid}&accountid=${accountid}`;

// 用window.open打开支付页
    window.open(payUrl, '_blank', 'width=800,height=600,top=100,left=100');
}
</script>
```

```
if ($sign == $mysign && $trade_status == 'TRADE_SUCCESS') {
    echo "<script>
        alert('支付成功！即将返回游戏。');
        window.close(); // 关闭当前支付标签页
    </script>";
} else {
    echo "<script>alert('支付失败，请重试！');history.back();</script>";
}
```
