应用内购买 (macOS)

    iTunes Connect 开发人员帮助: 协议、税务和银行概述

    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. const { inAppPurchase } = require('electron').remote
    2. const PRODUCT_IDS = ['id1', 'id2']
    4. // 尽早监听transactions事件.
    5. inAppPurchase.on('transactions-updated', (event, transactions) => {
    6.   if (!Array.isArray(transactions)) {
    7.     return
    8.   }
    10.   // 检查每一笔交易.
    11.   transactions.forEach(function (transaction) {
    12.     var payment = transaction.payment
    14.     switch (transaction.transactionState) {
    15.       case 'purchasing':
    16.         console.log(`Purchasing ${payment.productIdentifier}...`)
    17.         break
    18.       case 'purchased':
    20.         console.log(`${payment.productIdentifier} purchased.`)
    22.         // 获取收据的url.
    23.         let receiptURL = inAppPurchase.getReceiptURL()
    25.         console.log(`Receipt URL: ${receiptURL}`)
    27.         // @see https://developer.apple.com/library/content/releasenotes/General/ValidateAppStoreReceipt/Chapters/ValidateRemotely.html
    28.         // ...
    29.         // 如果收据通过校验，说明产品已经被购买了
    30.         // ...
    32.         // 交易完成.
    33.         inAppPurchase.finishTransactionByDate(transaction.transactionDate)
    35.         break
    36.       case 'failed':
    38.         console.log(`Failed to purchase ${payment.productIdentifier}.`)
    40.         // 交易完成.
    41.         inAppPurchase.finishTransactionByDate(transaction.transactionDate)
    43.         break
    44.       case 'restored':
    46.         console.log(`The purchase of ${payment.productIdentifier} has been restored.`)
    48.         break
    49.       case 'deferred':
    51.         console.log(`The purchase of ${payment.productIdentifier} has been deferred.`)
    53.         break
    54.       default:
    55.         break
    56.     }
    57.   })
    59. // 检查用户是否允许当前app启用应用内购买功能.
    60. if (!inAppPurchase.canMakePayments()) {
    61.   console.log('The user is not allowed to make in-app purchase.')
    62. }
    64. // 检索并显示产品描述.
    65. inAppPurchase.getProducts(PRODUCT_IDS).then(products => {
    66.   // 检查参数.
    67.   if (!Array.isArray(products) || products.length <= 0) {
    68.     console.log('Unable to retrieve the product informations.')
    69.     return
    70.   }
    72.   // 显示每个产品的名称和价格.
    73.   products.forEach(product => {
    74.     console.log(`The price of ${product.localizedTitle} is ${product.formattedPrice}.`)
    75.   })
    77.   // 询问用户需要购买哪个产品.
    78.   let selectedProduct = products[0]
    79.   let selectedQuantity = 1
    81.   // 购买选中的产品.
    82.   inAppPurchase.purchaseProduct(selectedProduct.productIdentifier, selectedQuantity).then(isProductValid => {
    83.     if (!isProductValid) {
    84.       console.log('The product is not valid.')
    85.       return
    86.     }
    88.     console.log('The payment has been added to the payment queue.')
    89. })
