我正在尝试执行以下Parse.Cloud.httpRequest请求，作为信用卡注册（令牌化）过程的一部分：
var cardRegistrationResponse = Parse.Cloud.httpRequest({
method: 'POST',
url: cardRegistrationURL,
headers: {
'Content-Type': 'application/x-www-form-urlencoded',
},
body: {
'accessKeyRef': accessKey,
'cardNumber': cardInfo.number,
'cardExpirationDate': cardInfo.expirationDate,
'cardCvx': cardInfo.cvx,
'data': preRegistrationData
}
});
作为Parse Cloud功能的一部分，我使用PFCloud.callFunction在我的iOS应用程序中调用。但是Parse.Cloud方面的事情似乎在执行请求时失败（在记录所有body参数值后立即记录停止。见下文）并且iOS端报告以下错误：
2015-12-17 11:32:47.494 Nestor[37909:5680550] [Error]: Uncaught SyntaxError: Unexpected token d in <unknown file>:1 (Code: 141, Version: 1.11.0)
这里云控制台日志转储了body参数：
I2015-12-17T10:32:46.363Z]cardNumber: 4970100000000154
I2015-12-17T10:32:46.364Z]cardExpirationDate: 0417

我不知道发生了什么事。任何帮助将不胜感激。
所以要把事情放在上下文中，这里是完整的Parse.Cloud函数：
// Register a credit card for a later use.
//
// Request params may include:
// - 'credentials': a JSON object with a bearer 'access_token'
//
// Request params must include a 'cardInfo' dictionary with the following keys:
// - 'paymentUserId': the card owner user id in the payment platform
// - 'number': the card number
// - 'expirationDate': the card expiration date in format 'MMYY'
// - 'cvx': the card security code in the format 'NNN'
// - 'currency': the card currency 3-letter code, eg 'EUR'
// - 'type': the card type, one of 'CB_VISA_MASTERCARD', 'DINERS', or 'MAESTRO'
//
// Returns a JSON object that contains the registered card info:
// - 'cardId': the id of the registered card in the payment platform
// - 'partialNumber': the partially obfuscated card number
// - 'expirationDate': the card expiration date in the format 'MMYY'
// - 'provider': the card provider, one of 'VISA', 'MASTERCARD'...
Parse.Cloud.define("registerCard", function(request, response) {
var credentials = request.params.credentials;
var cardInfo = request.params.cardInfo;
Parse.Promise.as(credentials).then(function(credentials) {
// Make sure we have credentials
if (typeof credentials === 'undefined') {
return Parse.Cloud.run("authorize")
} else {
return Parse.Promise.as(credentials)
}
}).then(function(credentials) {
// Step 1: PREREGISTRATION
var cred = Parse.Promise.as(credentials);
// var preCardRegistrationResponse = preCardRegistration(credentials, cardInfo);
console.log("Pre-registration");
console.log("CardType: " + cardInfo.type);
console.log("Currency: " + cardInfo.currency);
console.log("UserId: " + cardInfo.userId);
var preCardRegistrationResponse = Parse.Cloud.httpRequest({

'Currency': cardInfo.currency,
// mangopay user id
'UserId': cardInfo.userId
}
});
return Parse.Promise.when(cred, preCardRegistrationResponse);
}).then(function(credentials, preCardRegistrationResponse) {
// Step 2: REGISTRATION
var cred = Parse.Promise.as(credentials);
var preCardRegistrationInfo = JSON.parse(preCardRegistrationResponse.text);
// var cardRegistrationResponse = cardRegistration(credentials, cardInfo, preCardRegistrationInfo);
var cardRegistrationURL = preCardRegistrationInfo.CardRegistrationURL;
var preRegistrationData = preCardRegistrationInfo.PreregistrationData;

console.log("cardCvx: " + cardInfo.cvx);
console.log("data: " + preRegistrationData);
console.log("typeof accessKeyRef is " + (typeof accessKey) );
console.log("typeof cardNumber is " + (typeof cardInfo.number) );
console.log("typeof expirationDate is " + (typeof cardInfo.expirationDate) );
console.log("typeof cardCvx is " + (typeof cardInfo.cvx) );
console.log("typeof data is " + (typeof preRegistrationData) );
var cardRegistrationResponse = Parse.Cloud.httpRequest({
method: 'POST',
url: cardRegistrationURL,
// Default to url form encoded
// headers: {
// 'Content-Type': 'application/x-www-form-urlencoded',
// },
body: {
'accessKeyRef': accessKey,
'cardNumber': cardInfo.number,
'cardExpirationDate': cardInfo.expirationDate,
'cardCvx': cardInfo.cvx,
'data': preRegistrationData
}
});
return Parse.Promise.when(cred, cardRegistrationResponse);
}).then(function(credentials, cardRegistrationResponse) {
// Step 3: POSTREGISTRATION
var cardRegistrationInfo = JSON.parse(cardRegistrationResponse.text);
// var postCardRegistrationResponse = postCardRegistration(credentials, cardRegistrationInfo);
var cardId = cardRegistrationInfo.Id;
var postCardRegistration = Parse.Cloud.httpRequest({
method: 'PUT',
url: mango_api_url + '/v2/sbsquare2015/cardRegistration/' + cardId,
headers: {
'Content-Type': 'application/json;charset=utf-8'
},
body: cardRegistrationInfo
});
return postCardRegistrationResponse;
}).then(function(postCardRegistrationResponse) {
// TRANSFORMATION
var cardRegistrationInfo = JSON.parse(postCardRegistrationResponse.text);
console.log("cardId: " + cardRegistrationInfo.CardId);
console.log("expirationDate: " + cardInfo.expirationDate);
console.log("provider: " + cardRegistrationInfo.CardProvider);
var registeredCard = {
'cardId': cardRegistration.CardId,
'partialNumber': cardInfo.number.slice(0, 6) + '******' + cardInfo.number.slice(12, 16),
'expirationDate': cardInfo.expirationDate,
'provider': cardRegistrationInfo.CardProvider
}
return Parse.Promise.as(registeredCard);
}).then(function(registeredCard) {
console.log("Registered card " + registeredCard);
response.success(registeredCard);
}, function(error) {
console.log("Card registration failed: " + error);
response.error(error);
});
});
附注：我已经在Paw和iOS Swift客户端中测试了整个卡注册，但我试图在服务器端实现它，所以我不必编写Android客户端作为好吧......
但云版本在第2步停止，我在调用Parse Cloud函数＆＃39; registerCard＆＃39;时，在我的iOS客户端中收到上述错误。
旁注：我不确定我是否正确使用Promise。我希望能调用最后一个错误函数，但它不是......
感谢您的帮助
