内容安全策略阻止 javascript 表单提交到 php 服务器

Question

有人可以帮忙解决这个恼人的问题吗？我正在尝试向我的服务器提交一个 Stripe 表单。我的 header <script src="https://js.stripe.com/v3/"></script> 中有他们的 link。每次我点击表单按钮时，都没有任何反应，因为 CSP 阻止了表单提交。看起来 Firefox 正在注入某种脚本？如何解决这个问题？我在本地主机上。

Javascript

var stripe = Stripe('pk_test_test');
var elements = stripe.elements();
    // Handle form submission
    var form = document.getElementById('payment-form');

    form.addEventListener('submitpayment', function(event) {
        event.preventDefault();

    stripe.createToken(card).then(function(result) {
            if (result.error) {
                // Inform the user if there was an error
                var errorElement = document.getElementById('card-errors');
                errorElement.textContent = result.error.message;
            } else {
                stripeTokenHandler(result.token);
            }
        });
    });

    // Send Stripe Token to Server
    function stripeTokenHandler(token) {
        // Insert the token ID into the form so it gets submitted to the server
        var form = document.getElementById('payment-form');

    // Add Stripe Token to hidden input
        var hiddenInput = document.createElement('input');
        hiddenInput.setAttribute('type', 'hidden');
        hiddenInput.setAttribute('name', 'stripeToken');
        hiddenInput.setAttribute('value', token.id);
        form.appendChild(hiddenInput);

    // Submit form
     form.submit();
    }

在这种特殊情况下，是 AdGuard FireFox 插件导致了这个问题。

更多资源：

看起来您是运行 AdGuard 扩展（AG_onLoad、Google Search，所以这可能是罪魁祸首
这个 CSP Github Page 是一个很好的资源，但是 _PostRPC 调用在 unexplained .md 文档中。
看起来这可能与this GitHub issue有关 - 显然FF对CSP的应用非常严格

如果禁用所有加载项，能否验证它是否正常工作？

HTH！
