我们尝试使用Braintree设置每月订阅计划。
我们看看https://developers.braintreepayments.com/start/hello-client/javascript/v3
我下载了以下代码片段,并将其另存为本地HTML文件在我的计算机中。 (我知道我需要使用后端服务器来为客户端浏览器生成令牌和下面的HTML代码片段。我只是想做一个快速测试,而无需先设置服务器。)
<head>
<meta charset="utf-8">
<script src="https://js.braintreegateway.com/web/dropin/1.12.0/js/dropin.min.js"></script>
</head>
<body>
<div id="dropin-container"></div>
<button id="submit-button">Request payment method</button>
<script>
var button = document.querySelector('#submit-button');
braintree.dropin.create({
authorization: 'CLIENT_TOKEN_FROM_SERVER',
container: '#dropin-container'
}, function (createErr, instance) {
button.addEventListener('click', function () {
instance.requestPaymentMethod(function (err, payload) {
// Submit payload.nonce to your server
});
});
});
</script>
</body>
我们单击按钮。 instance.requestPaymentMethod
正在执行。
我希望客户端浏览器将开始与braintree服务器通信,如步骤3所示。
我可以知道我错过了什么步骤吗?
答案 0 :(得分:1)
您需要设置适当的后端服务器,才能使前端代码正常工作。因为没有正确的client_token
(从后端服务器生成),前端代码将无法工作。
前端代码不会对client_token
错误提供任何警告。
请注意,由于Braintree文档编写得不好,您将很难设置后端服务器
连续花费2天后,我发布了有关每月定期结算的代码段。

不同的API调用将产生不同的Result
对象,但具有不同的属性。我怎么知道我需要打电话给payment_method_token = result.payment_method.token
来获取payment_method_token。您无法通过阅读文档来分辨。您需要使用pprint(vars(result))
对结果对象执行调试。 如果来自Braintree的人可以告诉我,我将非常高兴,如何通过阅读文档来查找此类信息。
命名很糟糕且令人困惑。例如,商家帐户和商家帐户ID 是两种不同的方式。
