android - 如何在 Android 中使用 Simplify Commerce Payment API？

Question

我正在尝试从卡 token 创建付款在我的 android 程序中，如下链接所示:

Sample usage of payment api

我无法使用 Simplify Commerce Android SDK 创建“支付”对象，因此我通过将此行添加到我的 gradle 构建中来包含 java 支付 SDK

compile 'com.simplify:payments-sdk-java:1.3.0'

添加此行后我可以导入“com.simplify.payments”包并创建支付对象，但这次我的 android 构建失败(因为我使用 java sdk？)。

全面披露:这并没有回答如何在您的应用中包含支付 API 的问题，而是为您指明了使用 Simplify 在您的应用中收款的正确方向。

您绝对不应该尝试在您的 Android 应用程序中使用 payments java sdk。这样做需要您提供您的私有(private) API key ，并且会带来严重的安全问题。请参阅:https://github.com/simplifycom/simplify-android-sample/wiki/Simplify-Android-SDK-Tutorial#process-a-payment

Friendly reminder: DO NOT BUNDLE YOUR PRIVATE KEY WITHIN YOUR APP!

Your private keys are considered sacred and can be used to process payments, issue refunds, and more. A common development mistake is to simply include the Java SDK in an app and use a private key to complete the transaction lifecycle without involving a server. While it may seem like an easy way to integrate payments, distributing your private key in an app leaves it vulnerable through simple reverse engineering. Once compromised, an attacker can use your key to perform almost every operation offered through our APIs. This is bad security practice. In addition, since keys can be revoked from the API Keys page, they are also considered volatile. If a private key is revoked, any app using it will be broken until an update is released with a new key. The bottom line is this: Don't do it. We will find you. :)

好消息是 Simplify 提供了一个 Android SDK，您可以使用它在您的应用程序中收集和标记卡信息。只需将其包含在以下行中:

compile 'com.simplify:simplify-android:2.0.3'
