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']
  3. // 尽早监听transactions事件.
  4. inAppPurchase.on('transactions-updated', (event, transactions) => {
  5. if (!Array.isArray(transactions)) {
  6. return
  7. }
  8. // 检查每一笔交易.
  9. transactions.forEach(function (transaction) {
  10. var payment = transaction.payment
  11. switch (transaction.transactionState) {
  12. case 'purchasing':
  13. console.log(`Purchasing ${payment.productIdentifier}...`)
  14. break
  15. case 'purchased':
  16. console.log(`${payment.productIdentifier} purchased.`)
  17. // 获取收据的url.
  18. let receiptURL = inAppPurchase.getReceiptURL()
  19. console.log(`Receipt URL: ${receiptURL}`)
  20. // 将收据提交到服务器并校验收据是否有效.
  21. // @see https://developer.apple.com/library/content/releasenotes/General/ValidateAppStoreReceipt/Chapters/ValidateRemotely.html
  22. // ...
  23. // 如果收据通过校验,说明产品已经被购买了
  24. // ...
  25. // 交易完成.
  26. inAppPurchase.finishTransactionByDate(transaction.transactionDate)
  27. break
  28. case 'failed':
  29. console.log(`Failed to purchase ${payment.productIdentifier}.`)
  30. // 交易完成.
  31. inAppPurchase.finishTransactionByDate(transaction.transactionDate)
  32. break
  33. case 'restored':
  34. console.log(`The purchase of ${payment.productIdentifier} has been restored.`)
  35. break
  36. case 'deferred':
  37. console.log(`The purchase of ${payment.productIdentifier} has been deferred.`)
  38. break
  39. default:
  40. break
  41. }
  42. })
  43. })
  44. // 检查用户是否允许当前app启用应用内购买功能.
  45. if (!inAppPurchase.canMakePayments()) {
  46. console.log('The user is not allowed to make in-app purchase.')
  47. }
  48. // 检索并显示产品描述.
  49. inAppPurchase.getProducts(PRODUCT_IDS).then(products => {
  50. // 检查参数.
  51. if (!Array.isArray(products) || products.length <= 0) {
  52. console.log('Unable to retrieve the product informations.')
  53. return
  54. }
  55. // 显示每个产品的名称和价格.
  56. products.forEach(product => {
  57. console.log(`The price of ${product.localizedTitle} is ${product.formattedPrice}.`)
  58. })
  59. // 询问用户需要购买哪个产品.
  60. let selectedProduct = products[0]
  61. let selectedQuantity = 1
  62. // 购买选中的产品.
  63. inAppPurchase.purchaseProduct(selectedProduct.productIdentifier, selectedQuantity).then(isProductValid => {
  64. if (!isProductValid) {
  65. console.log('The product is not valid.')
  66. return
  67. }
  68. console.log('The payment has been added to the payment queue.')
  69. })
  70. })
