Php Braintree沙盒支付尝试出现错误404

我正试图在一个基于Laravel7的项目上实现一个Braintree沙盒支付小部件。我试过很多指南，但结果总是一样的。 当我试图付款时，我在post请求中出现了404错误。以下是刀片代码：

<form method="post" id="payment-form" action="{{ url('/checkout') }}">
    @csrf
    @method('POST')
    <section>
        <label for="amount">
            <span class="input-label">Amount</span>
            <div class="input-wrapper amount-wrapper">
                <input id="amount" name="amount" type="tel" min="1" placeholder="Amount" value="10">
            </div>
        </label>

        <div class="bt-drop-in-wrapper">
            <div id="bt-dropin"></div>
        </div>
    </section>

    <input id="nonce" name="payment_method_nonce" type="hidden" />
    <button class="button" type="submit"><span>Test Transaction</span></button>
</form>

目前，我们正在通过php artisan Service在本地主机上运行该项目

很抱歉在代码中插入意大利语注释

希望有人能提供帮助。

尝试在路线代码的开头添加一个

dd（“”）

，看看它是否正在运行。如果不是，这可能是一个路由问题，而不是Braintree问题。我曾尝试将其放入post函数中，但它实际上没有运行dd，我不明白为什么它实际上需要数量、nonce和令牌（在同一个函数中定义），但不运行任何其他功能…你把它放在哪里，在

/checkout

路由的处理程序的最顶部？如果是这样，则意味着您的应用程序没有正确地路由

/checkout

，因此这不是大脑树问题。如果没有，请尝试添加

dd（$amount，$nonce）$request

获取这些输入。
