使用云代码验证自动续订订阅收据并更新Parse

我正在开发一个使用Parse作为后端的iOS应用程序，并且用户使用Apple的自动续订订阅IAP进行订阅。在订阅和恢复购买功能期间，我将收据作为云代码函数中的参数传递，然后通过Parse将其发送到Apple的服务器，如this SO answer中所述。使用云代码验证自动续订订阅收据并更新Parse

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函数必须稍微偏离一点，因为我的控制台显示Result: TypeError: Cannot read property 'status' of undefined，这意味着HTTPResponse.data是未定义的（？）。我的功能如下，然后是控制台日志。

而且，我不是我是否应该使用receipt，latest_receipt，或latest_receipt_info用于访问expires_date产权清晰的100％，所以我在那里有一些额外的变量只是为了测试什么出来。

（感谢您的帮助，云代码是我曾经写过的唯一的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); 
    } 
}) 

});

它看起来像var json = httpResponse.data;未定义 – messerbill

是的，这就是它告诉我的，但我不明白为什么它是未定义的。 – blwinters

尝试在控制台中打印httpResponse – messerbill

试试这个：

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

解决这个问题对我来说。
