变更 CFBundleIdentifier

To test In-App Purchase in development with Electron you'll have to change the CFBundleIdentifier in node_modules/electron/dist/Electron.app/Contents/Info.plist. You have to replace com.github.electron by the bundle identifier of the application you created with iTunes Connect.

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

Code example

Here is an example that shows how to use In-App Purchases in Electron. You'll have to replace the product ids by the identifiers of the products created with iTunes Connect (the identifier of com.example.app.product1 is product1). Note that you have to listen to the transactions-updated event as soon as possible in your app.

  1. const { inAppPurchase } = require('electron').remote
  2. const PRODUCT_IDS = ['id1', 'id2']
  4. // Listen for transactions as soon as possible.
  5. inAppPurchase.on('transactions-updated', (event, transactions) => {
  6.   if (!Array.isArray(transactions)) {
  7.     return
  8.   }
  10.   // Check each transaction.
  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.         // Get the receipt url.
  23.         let 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.         // If the receipt is valid, the product is purchased
  31.         // ...
  33.         // Finish the transaction.
  34.         inAppPurchase.finishTransactionByDate(transaction.transactionDate)
  36.         break
  37.       case 'failed':
  39.         console.log(`Failed to purchase ${payment.productIdentifier}.`)
  41.         // Finish the transaction.
  42.         inAppPurchase.finishTransactionByDate(transaction.transactionDate)
  44.         break
  45.       case 'restored':
  47.         console.log(`The purchase of ${payment.productIdentifier} has been restored.`)
  49.         break
  50.       case 'deferred':
  52.         console.log(`The purchase of ${payment.productIdentifier} has been deferred.`)
  54.         break
  55.       default:
  56.         break
  57.     }
  58.   })
  59. })
  61. // Check if the user is allowed to make in-app purchase.
  62. if (!inAppPurchase.canMakePayments()) {
  63.   console.log('The user is not allowed to make in-app purchase.')
  64. }
  66. // Retrieve and display the product descriptions.
  67. inAppPurchase.getProducts(PRODUCT_IDS).then(products => {
  68.   // Check the parameters.
  69.   if (!Array.isArray(products) || products.length <= 0) {
  70.     console.log('Unable to retrieve the product informations.')
  71.     return
  72.   }
  74.   // Display the name and price of each product.
  75.   products.forEach(product => {
  76.     console.log(`The price of ${product.localizedTitle} is ${product.formattedPrice}.`)
  77.   })
  79.   // Ask the user which product he/she wants to purchase.
  80.   let selectedProduct = products[0]
  81.   let selectedQuantity = 1
  83.   // Purchase the selected product.
  84.   inAppPurchase.purchaseProduct(selectedProduct.productIdentifier, selectedQuantity).then(isProductValid => {
  85.     if (!isProductValid) {
  86.       console.log('The product is not valid.')
  87.       return
  88.     }
  90.     console.log('The payment has been added to the payment queue.')
  91.   })
  92. })
