使用 Cloud Code 验证自动更新订阅收据和更新 Parse

Question

我正在开发一个 iOS 应用，它使用 Parse 作为后端，用户使用 Apple 的自动更新订阅 IAP 进行订阅。在订阅和恢复购买功能期间，我将收据作为参数传递给云代码函数，然后通过 Parse 将其 POST 到 Apple 的服务器，如 this SO answer 中所述。

我想解析 HTTPResponse 并使用 JSON 收据的 expires_date 属性更新 Parse 中的用户对象。我认为我的 Cloud Code 功能必须关闭一点，因为我的控制台显示 Result: TypeError: Cannot read property 'status' of undefined，这意味着 HTTPResponse.data 未定义（？）。我的功能如下，然后是控制台日志。

另外，我不是 100% 清楚是否应该使用 receipt、latest_receipt 或 latest_receipt_info 来访问 expires_date 属性，所以我有一些额外的变量来测试什么出来了。

（感谢您的帮助，因为 Cloud Code 是我编写过的唯一 JavaScript。）

Parse.Cloud.define('validateReceipt', function (request, response) {
var user = request.user;
var receiptAsBase64EncodedString = request.params.receiptData;

var postData = {
    method: 'POST',
    url: 'https://sandbox.itunes.apple.com/verifyReceipt',
    body: { 'receipt-data': receiptAsBase64EncodedString,
            'password': 'SECRET' }
}

Parse.Cloud.httpRequest(postData).then(function (httpResponse) {
    // httpResponse is a Parse.Cloud.HTTPResponse

    var json = httpResponse.data; // Response body as a JavaScript object.
    var validationStatus = json.status; // App Store validation status code. If 0, the receipt is valid, but may be expired
    var receiptJSON = json.receipt; // Receipt data as a JSON object
    var latestReceipt = json.latest_receipt; 
    var latestReceiptInfo = json.latest_receipt_info;

    console.log('JSON: ' + json);

    console.log('Latest Receipt Info: ' + latestReceiptInfo);

    console.log('Validation status: ' + validationStatus);

    var now = new Date().getTime();
    var expirationDate = latestReceiptInfo.expires_date;
    console.log('Now: ' + now)
    console.log('Expiration Date: ' + expirationDate)


    if (expirationDate > now) { //updates expiration date
        user.set("accountExpDate", expirationDate);
        user.set("accountStatus", 1);
        user.save();

        return response.success('Subscription Active, expiration date: ' + expirationDate);

    } else {
        user.set("accountStatus", 2);
        user.save();

        return response.error('Subscription Expired, expiration date: ' + expirationDate);
    }
})

});

console.log(JSON.stringify(httpResponse, null, 4));给了我

Answer 1

试试这个：

var validationStatus = JSON.parse(httpResponse["text"])["status"];

为我解决了问题。
