使用srmklive/paypal集成PayPal支付时获取正确交易ID的问题

问题原因及解决方案

你当前获取的$response['id']是PayPal的订单ID，而卖家账户交易记录里显示的是资金捕获（Capture）的交易ID，二者属于PayPal支付流程中不同的实体标识，所以不一致。

修正代码

需要从响应的captures节点中提取真实的交易ID，修改代码中交易ID的赋值部分即可：

// 替换原交易ID赋值代码
$save_transaction->transaction_id = $response['purchase_units'][0]['payments']['captures'][0]['id'];
// 同时修改返回给视图的transaction_id
$transaction_id = $response['purchase_units'][0]['payments']['captures'][0]['id'];

修改后的完整控制器逻辑片段：

if (isset($response['status']) && $response['status'] == 'COMPLETED') {
    if(isset($video_id) && !empty($video_id))
    {
        $save_transaction = new Transcation();
        $save_transaction->user_id = Auth::user()->id;
        $save_transaction->item_type = 'video';
        $save_transaction->item_id = $video_id;
        $save_transaction->amount = $response['purchase_units'][0]['payments']['captures'][0]['amount']['value'];
        // 修正：获取捕获的交易ID
        $save_transaction->transaction_id = $response['purchase_units'][0]['payments']['captures'][0]['id'];
        $save_transaction->transaction_type = 'paypal';
        $save_transaction->is_payment_done = 1;
        $save_transaction->save();
    }
    $message = 'Your transaction is completed successfully!';
    // 同步修正返回的交易ID
    $transaction_id = $response['purchase_units'][0]['payments']['captures'][0]['id'];
    return view('frontend.payment.success_payment',compact('message','transaction_id'));
}
