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
。
<key>CFBundleIdentifier</key>
<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。
const { inAppPurchase } = require('electron').remote
const PRODUCT_IDS = ['id1', 'id2']
// 尽早监听transactions事件.
inAppPurchase.on('transactions-updated', (event, transactions) => {
if (!Array.isArray(transactions)) {
return
}
// 检查每一笔交易.
transactions.forEach(function (transaction) {
let payment = transaction.payment
switch (transaction.transactionState) {
case 'purchasing':
console.log(`Purchasing ${payment.productIdentifier}...`)
break
case 'purchased':
console.log(`${payment.productIdentifier} purchased.`)
// Get the receipt url.
let receiptURL = inAppPurchase.getReceiptURL()
console.log(`Receipt URL: ${receiptURL}`)
// 将收据提交到服务器并校验收据是否有效.
// @see https://developer.apple.com/library/content/releasenotes/General/ValidateAppStoreReceipt/Chapters/ValidateRemotely.html
// ...
// 如果收据通过校验,说明产品已经被购买了
// ...
// 交易完成.
inAppPurchase.finishTransactionByDate(transaction.transactionDate)
break
case 'failed':
console.log(`Failed to purchase ${payment.productIdentifier}.`)
// 交易完成.
inAppPurchase.finishTransactionByDate(transaction.transactionDate)
break
case 'restored':
console.log(`The purchase of ${payment.productIdentifier} has been restored.`)
break
case 'deferred':
console.log(`The purchase of ${payment.productIdentifier} has been deferred.`)
break
default:
break
}
})
})
// 检查用户是否允许当前app启用应用内购买功能.
if (!inAppPurchase.canMakePayments()) {
console.log('The user is not allowed to make in-app purchase.')
}
// 检索并显示产品描述.
inAppPurchase.getProducts(PRODUCT_IDS).then(products => {
// 检查参数.
if (!Array.isArray(products) || products.length <= 0) {
console.log('Unable to retrieve the product informations.')
return
}
// 显示每个产品的名称和价格.
products.forEach(product => {
console.log(`The price of ${product.localizedTitle} is ${product.formattedPrice}.`)
})
// 询问用户需要购买哪个产品.
let selectedProduct = products[0]
let selectedQuantity = 1
// 购买选中的产品.
inAppPurchase.purchaseProduct(selectedProduct.productIdentifier, selectedQuantity).then(isProductValid => {
if (!isProductValid) {
console.log('The product is not valid.')
return
}
console.log('The payment has been added to the payment queue.')
})
})
