沙盒测试模式下Android系统中Paypal支付网关的集成问题

Question

此外，我尝试了生产模式，改变所有需要的设置，但在本例中得到
429-多次击中问题。

我花了一整天的时间和我的朋友一起解决这个问题，但没有找到成功。

1-贝宝限制沙箱测试模式还是只在印度限制此服务？
2-解决此问题的解决方案是什么？

还是贝宝删除沙箱测试服务，或者我需要为贝宝集成实现BrainTree SDK？

Answer 1

PayPal Android SDK是不推荐的，所以看起来你使用的是一个不推荐的解决方案。如果您需要一个本地SDK，通过Braintree快速结账是唯一可用的。但是，您确实需要一个服务器或webservice来使用Braintree，因为该集成有一个服务器端部分。

或者，您可以在服务器或webservice上集成v2 Create Order API，并使用rel：Approve URL从本机应用程序打开浏览器，并将返回URL设置为应用程序的deeplink，然后从服务器触发捕获命令调用。

正如您所看到的，所有解决方案都需要一个服务器或WebService。
