应用内购买 (macOS)

    iTunes Connect开发人员帮助：创建应用程序内购买

    代码示例

    通过下面的例子来了解如何在Electron中使用应用内购买功能。 您必须使用通过ITunes Connect创建的产品的唯一标识 （ID）来替换掉下面示例中的PRODUCT_IDS。( com.example.app.product1 的ID是 product1)。 请注意，您必须尽可能早的在你的应用中监听transactions-updated事件。

    1. // 主进程
    2. const { inAppPurchase } = require('electron')
    3. const PRODUCT_IDS = ['id1', 'id2']
    5. // 监听交易尽快进行。
    6. inAppPurchase.on('transactions-updated', (event, transactions) => {
    7.   if (!Array.isArray(transactions)) {
    8.     return
    9.   }
    11.   // 检查每一笔交易.
    12.   transactions.forEach(function (transaction) }
    13.     const pay = transactions. ayment
    15.     开关(交易)。 赎金动作状态(
