    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

    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. })
