Ionic 中的 Braintree Drop-in 容器

Question

我正在尝试将 Braintree Payments 插件集成到 Ionic 移动应用中。根据我在网上找到的 Braintree 文档和一些代码示例，以下代码是我迄今为止设法提出的，但它似乎不起作用：

controller.js

.controller('CheckoutForm', function($scope, $window) {
  $scope.clientToken = "<token generated by the server>"

  $scope.renderCheckout = function() {
    braintree.setup($scope.clientToken, "dropin", {
      container: "payment-form"
      });
  }
})

模板.html

<div>
  Payment details:
  <form id="checkout">
    <div id="payment-form" onLoad="renderCheckout()"></div>
  </form>
</div>

我还在 index.html 中包含以下行：

<script src="https://js.braintreegateway.com/js/braintree-2.23.0.min.js"></script>

总的来说，我对 Ionic 和 HTML5/JS 开发还很陌生，因此非常感谢任何帮助。

Answer 1

“thepio”建议仅用于测试。但正确的方法可能是在您的服务器上生成客户端令牌。然后您的 Ionic 应用程序将发布并从您的服务器获取客户端令牌。然后一旦生成付款随机数，您就可以将付款数据发布到您的服务器以处理付款。

检查此示例实现。 https://github.com/demianborba/braintree-cordova-angular-node

Answer 2

忘记 onload 函数。只需在您的控制器中执行此操作即可。

var clientToken = "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";

// Client token above is just for testing and provided by Braintree for testing purposes

braintree.setup(clientToken, "dropin", {
  container: "payment-form"
});

然后在你的html中：

<form id="checkout">
  <div id="payment-form"></div>
</form>

对于移动设备，请记住使用 cordova-whitelist-plugin 添加适当的内容安全策略和白名单。
