    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. // Main process
    2. const { inAppPurchase } = require('electron')
    3. const PRODUCT_IDS = ['id1', 'id2']
    5. // Listen for transactions as soon as possible.
    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((transaction) => {
    13.     const payment = transaction.payment
    15.     switch (transaction.transactionState) {
    16.       case 'purchasing':
    17.         console.log(`Purchasing ${payment.productIdentifier}...`)
    18.         break
    20.       case 'purchased': {
    21.         console.log(`${payment.productIdentifier} purchased.`)
    23.         // Get the receipt url.
    24.         const receiptURL = inAppPurchase.getReceiptURL()
    26.         console.log(`Receipt URL: ${receiptURL}`)
    28.         // @see https://developer.apple.com/library/content/releasenotes/General/ValidateAppStoreReceipt/Chapters/ValidateRemotely.html
    29.         // ...
    30.         // 如果收据通过校验，说明产品已经被购买了
    31.         // ...
    33.         // 交易完成.
    34.         inAppPurchase.finishTransactionByDate(transaction.transactionDate)
    36.         break
    37.       }
    39.       case 'failed':
    41.         console.log(`Failed to purchase ${payment.productIdentifier}.`)
    43.         // 终止交易
    44.         inAppPurchase.finishTransactionByDate(transaction.transactionDate)
    46.         break
    47.       case 'restored':
    49.         console.log(`The purchase of ${payment.productIdentifier} has been restored.`)
    51.         break
    52.       case 'deferred':
    54.         console.log(`The purchase of ${payment.productIdentifier} has been deferred.`)
    56.         break
    57.       default:
    58.         break
    59.     }
    60. })
    62. // 检查用户是否允许当前app启用应用内购买功能.
    63. if (!inAppPurchase.canMakePayments()) {
    64.   console.log('The user is not allowed to make in-app purchase.')
    65. }
    67. // Retrieve and display the product descriptions.
    68. inAppPurchase.getProducts(PRODUCT_IDS).then(products => {
    69.   // 检查参数.
    70.   if (!Array.isArray(products) || products.length <= 0) {
    71.     console.log('Unable to retrieve the product informations.')
    72.     return
    73.   }
    75.   // Display the name and price of each product.
    76.   products.forEach(product => {
    77.     console.log(`The price of ${product.localizedTitle} is ${product.formattedPrice}.`)
    78.   })
    80.   // Ask the user which product they want to purchase.
    81.   const selectedProduct = products[0]
    82.   const selectedQuantity = 1
    84.   // Purchase the selected product.
    85.   inAppPurchase.purchaseProduct(selectedProduct.productIdentifier, selectedQuantity).then(isProductValid => {
    86.     if (!isProductValid) {
    87.       console.log('The product is not valid.')
    88.       return
    89.     }
    91.     console.log('The payment has been added to the payment queue.')
    92. })
