应用内购买 (macOS)

准备工作

付费应用协议

如果你还没有，你需要在 iTunes Connect 签署付费应用协议, 并设置您的银行和税务信息。

创建您的应用内购买

然后，您需要在iTunes Connect中配置您的应用内购买，并包含名称，定价和说明等详细信息，以突出显示您的应用内购买的功能。

变更 CFBundleIdentifier

若要在Electron开发阶段对应用内购买功能进行测试，您必须在node_modules/electron/dist/Electron.app/Contents/Info.plist路径下修改CFBundleIdentifier。 您必须使用通过ITunes Connect创建的应用的bundle indentifier来替换掉com.github.electron。

  1. <key>CFBundleIdentifier</key>
  2. <string>com.example.app</string>

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.     const payment = transaction.payment
  14.     switch (transaction.transactionState) {
  15.       case 'purchasing':
  16.         console.log(`Purchasing ${payment.productIdentifier}...`)
  17.         break
  19.       case 'purchased': {
  20.         console.log(`${payment.productIdentifier} purchased.`)
  22.         // Get the receipt url.
  23.         const receiptURL = inAppPurchase.getReceiptURL()
  25.         console.log(`Receipt URL: ${receiptURL}`)
  27.         // Submit the receipt file to the server and check if it is valid.
  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.         // Finish the transaction.
  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.   })
  61. })
  63. // 检查用户是否允许当前app启用应用内购买功能.
  64. if (!inAppPurchase.canMakePayments()) {
  65.   console.log('The user is not allowed to make in-app purchase.')
  66. }
  68. // 检索并显示产品描述.
  69. inAppPurchase.getProducts(PRODUCT_IDS).then(products => {
  70.   // 检查参数.
  71.   if (!Array.isArray(products) || products.length <= 0) {
  72.     console.log('Unable to retrieve the product informations.')
  73.     return
  74.   }
  76.   // 显示每个产品的名称和价格.
  77.   products.forEach(product => {
  78.     console.log(`The price of ${product.localizedTitle} is ${product.formattedPrice}.`)
  79.   })
  81.   // 询问用户需要购买哪个产品.
  82.   const selectedProduct = products[0]
  83.   const selectedQuantity = 1
  85.   // Purchase the selected product.
  86.   inAppPurchase.purchaseProduct(selectedProduct.productIdentifier, selectedQuantity).then(isProductValid => {
  87.     if (!isProductValid) {
  88.       console.log('The product is not valid.')
  89.       return
  90.     }
  92.     console.log('The payment has been added to the payment queue.')
  93.   })
  94. })
