与表单价格相同的条带式计费

Question

所以我希望向客户（非用户）收取与条形表单中显示的金额相同的金额

<form action="/charge" method="POST">
                 {!! csrf_field() !!}
                  <script
                    src="https://checkout.stripe.com/checkout.js" class="stripe-button"
                    data-key="pk_test_key"
                    data-amount="{{ $note->price*100 }}"
                    data-name="Hello World"
                    data-description="{{$note->title}}"
                    data-image="/img/documentation/checkout/marketplace.png"
                    data-locale="auto"
                    data-currency="aud">
                  </script>
                </form>

在表格中显示的价格是相关钞票型号中列出的价格 * 100。我希望客户实际支付这个值，它会根据钞票而变化。

这是我的服务器帐单

public function charge()
{
    // Set your secret key: remember to change this to your live secret key in production
    // See your keys here https://dashboard.stripe.com/account/apikeys
    \Stripe\Stripe::setApiKey("sk_test_key");

    // Get the credit card details submitted by the form
    $token = $_POST['stripeToken'];

    // Create the charge on Stripe's servers - this will charge the user's card
    try {
      $charge = \Stripe\Charge::create(array(
        "amount" => 100, // amount in cents, again
        "currency" => "aud",
        "source" => $token,
        "description" => "Example charge"
        ));
    } catch(\Stripe\Error\Card $e) {
      // The card has been declined
    }

    return 'payment succesful';
}

我需要将“金额”设置为等于票据价值。

否则，付款将通过我的收银员测试帐户进行，并且大多数情况下其他一切都需要正常工作。

但客户不是注册用户。

数量必须是您在服务器端计算出来的，否则人们可以修改 DOM 并传递他们想要的任何数量。

相反，将id 存储在服务器端的缓存中，并将note 作为依赖项传递给charge 函数，然后比较2。

/**
 * Assuming name of "view" page
 */
public function checkout(Note $note) 
{
    /**
     * Always forget this on each page load, so we can switch seamlessly between Notes.
     */
    Illuminate\Support\Facades\Cache::forget('nid')->put('nid', $note->id);
}

不要忘记修改 charge 路由以包含对我们的 Note 依赖项的新引用

route::post('charge/{note}', 'Controller@charge')->name('charge');

确保更新您的表单以同时传递note

<form action="{{route('charge', $note)}}" method="POST">

旁注我喜欢命名路线，但这不是必需的。

然后在处理请求时，比较$nid 和$note->id

public function charge(Illuminate\Http\Request $request, Note $note)
{
    $nid = Illuminate\Support\Facades\Cache::get('nid');

    // id's match, no sneaky stuff. safe to use $note->price now
    if ($nid === $note->id) {
        //now we can process our payment.
        // Set your secret key: remember to change this to your live secret key in production
        // See your keys here https://dashboard.stripe.com/account/apikeys
        \Stripe\Stripe::setApiKey("sk_test_key");

        // Get the credit card details submitted by the form
        $token = $request->get('stripeToken');

        // Create the charge on Stripe's servers - this will charge the user's card
        try {
            $charge = \Stripe\Charge::create(array(
                "amount" => number_format($note->price, 0, '', ''), // amount in cents, again
                "currency" => "aud",
                "source" => $token,
                "description" => "Example charge"
            ));
        } catch(\Stripe\Error\Card $e) {
            // The card has been declined
        }    
    }
}
