Google Chrome：付款API返回購買交易失敗時失敗

Question

我在Chrome擴展程序內使用付款API進行應用內購買。

我能夠啓動一項購買，它可以運行並激活交易，但是回調會轉到onPurchaseFail而不是onPurchase。

清單：

"offline_enabled": true, 
"name": "__MSG_name__", 
"description": "__MSG_description__", 
"manifest_version": 2, 
"version": "1.1.2", 
"default_locale": "en", 
"icons": { 
    "128": "style/128_on.png" 
}, 
"background": { 
    "persistent": true, 
    "scripts": [ "js/jquery.min.js","js/bg.js" ] 
}, 
"browser_action": { 
    "default_title": "__MSG_name__", 
    "default_icon": "style/128_off.png", 
    "default_popup": "popup.html" 
}, 
"key": "...", 
"oauth2": { 
"client_id": "...", 
"scopes": [ "https://www.googleapis.com/auth/chromewebstore.readonly" ] 
}, 
"permissions": [ "*://*/*", "activeTab", "tabCapture", "tabs" ] 

API買入法：

google.payments.inapp.buy({ 
    parameters: {'env': "prod"}, 
    'sku': sku, 
    'success': onPurchase, 
    'failure': onPurchaseFailed 
}); 

我越來越：

onPurchaseFailed Object{ 
    checkoutOrderId:"10370910..." 
    response:Object{ 
    errorType:"PURCHASE_CANCELED"} 
} 

許可證被激活但是：

google.payments.inapp.getPurchases({ 
    'parameters': {'env': 'prod'}, 
    'success': onLicenseUpdate, 
    'failure': onLicenseUpdateFail 
}); 

個

回報：

createdTime: //some number 
itemId: //some string 
kind:"chromewebstore#payment" 
sku: //some string 
state:"ACTIVE" 

我有一個懷疑，這是因爲採購的窗口，當它關閉，這會觸發onPurchaseFailed回調發送取消消息。如何處理這個？

我發現的唯一方法是在失敗回調中檢查付款
