验证自动续订订阅收据并使用Cloud Code更新Parse。

Question

我正在开发一个iOS应用程序，使用Parse作为后端，用户使用苹果的自动续订订阅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Cloud Code函数，然后通过Parse将其POST到苹果服务器，如此SO答案所述。

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函数可能有点问题，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（？）。我的函数如下，后面是控制台日志。

此外，我不确定是否应该使用receipt，latest_receipt还是latest_receipt_info来访问expires_date属性，因此我在其中添加了一些额外的变量来测试输出结果。

（感谢任何帮助，因为Cloud Code是我写过的唯一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)); 输出了以下内容：

看起来 var json = httpResponse.data; 未定义。 - messerbill

是的，它告诉我那样，但我不明白为什么它是未定义的。 - blwinters

尝试使用JSON.stringify（httpResponse） - danh

终端给了我一个截断的版本，我已经将其添加到我的问题上面。 - blwinters

@blwinters 你能让这个工作吗？如果可以，你介意分享一下你成功的代码吗？非常感谢！ - Robert

Answer 1

试试这个：

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

解决了我的问题。
