使用带云代码的 Stripe + Parse 存储信用卡

Question

我正在尝试将用户信用卡存储到条带中。生成令牌后，我会尝试将用户的令牌作为客户保存到 Stripe。但是我没有找到任何问题的答案，我只需要为已经存在的用户存储一张卡。

我尝试使用 Stripe.Customers.update 方法，但如果用户有一张 "default" 卡，它会存储新卡并删除该卡。并使用方法 Stripe.Customers.create 它用新卡创建一个新客户，但我需要存储在特定用户中。

云代码：

Parse.Cloud.define("stripeCreateCard", function(request,response)
{
    Stripe.initialize(STRIPE_SECRET_KEY);
    Stripe.Customers.create
    (
        request.params,
        {
            success:function(results)
            {
                response.success(results);
            },
            error:function(error)
            {
                response.error("Error:" +error); 
            }
        }
    );
});

Parse.Cloud.define("stripeUpdateCustomer", function(request, response) 
{
    Stripe.initialize(STRIPE_SECRET_KEY);
    Stripe.Customers.update
    (
        request.params["customerId"],
        request.params["data"],
        {
            success:function(results)
            {
                console.log(results["id"]);
                response.success(results);
            },
            error:function(error)
            {
                response.error("Error:" +error); 
            }
        }
    );
});

iOS代码：

class func getParamsForAddingCardToCustomer(custormerId: String, cardToken: String) -> NSDictionary {
        let params = NSMutableDictionary()

        params.setObject(["card" : cardToken], forKey: "data")
        params.setObject(custormerId, forKey: "customerId")

        return params
}

var params = ParamsHelper.getParamsForAddingCardToCustomer(stripeId, cardToken: token)

PFCloud.callFunctionInBackground("stripeCreateCard", withParameters: params as [NSObject : AnyObject]) {
        (response: AnyObject?, error: NSError?) -> Void in
        let responseString = response as? String

        if (error === nil) {
            println("Response: \(responseString) ")
        }
        else if (error != nil) {
            println("Error: \(error) \(error!.userInfo)")
        }
    }

我尝试了几个参数来存储我需要的卡，但我总是报错'Received unknown parameters'

有人知道如何在不删除或创建新客户的情况下存储卡吗？

Parse 的 stripe 实现并不完整。在许多情况下，您必须使用 HTTPRequest 来执行 Parse 不提供的条带功能。

对于这些情况，我使用以下 iOS 方法和 CloudCode 来执行我所有的条带化 HTTPRequest。遵循 stripe CURL API 文档进行编码非常容易。然后我建立这个方法来执行大多数条纹任务，IE create/update/delete 客户、卡片、收费等

我首先为它提供一个方法，即 GET、POST、DELETE，具体取决于您是要检索、create/update 还是删除条带对象。

然后我将可选的 pre/suf/postfixes 组合起来，创建一个 url。

示例 URL 创建：

最后我给它参数，在创建卡并将其添加到客户的实例中，这只需要是包含 tokenID 的字典。

+(void)executeStripeCloudCodeWithMethod:(NSString *)method
                                 prefix:(NSString *)prefix
                                 suffix:(NSString *)suffix
                                postfix:(NSString *)postfix
                          secondPostfix:(NSString *)secondPostfix
                             parameters:(NSDictionary *)params
                      completionHandler:(ELStripeCompletionBlock)handler
{
    NSDictionary *parameters = @{@"method":method,
                                 @"prefix":prefix?prefix:@"",
                                 @"suffix":suffix?suffix:@"",
                                 @"postfix":postfix?postfix:@"",
                                 @"secondPostfix":secondPostfix?secondPostfix:@"",
                                 @"params":params?params:[NSNull null]
                                 };

    [PFCloud callFunctionInBackground:@"stripeHTTPRequest"
                       withParameters:parameters
                                block:^(id object, NSError *error) {
        id jsonObject;
        if (!error) {
            NSError *jsonError = nil;
            //Turn the json string into an NSDictionary
            jsonObject = [NSJSONSerialization JSONObjectWithData:[object dataUsingEncoding:NSUTF8StringEncoding]
                                                         options:kNilOptions error:&jsonError];

        }
        handler(jsonObject,error);
    }];
}

执行的云代码：

var STRIPE_SECRET_KEY = 'sk_test_your_test_code_here';
var STRIPE_API_BASE_URL = 'api.stripe.com/v1/'
Parse.Cloud.define("stripeHTTPRequest", function(request, response) 
{
    //Check for valid pre/suf/postfixes, if they are not there do not include them.
    var prefix = request.params["prefix"];
    var suffix = "";
    var postfix = "";
    var secondPostfix = "";
    if (!isEmpty(request.params["suffix"])) suffix = '/'+request.params['suffix'];  
    if (!isEmpty(request.params["postfix"])) postfix = '/'+request.params['postfix'];   
    if (!isEmpty(request.params["secondPostfix"])) secondPostfix = '/'+request.params['secondPostfix'];

    Parse.Cloud.httpRequest(
    {
            method: request.params["method"],
            //Create URL from base url and pre/suf/postfixes
            url: 'https://'+STRIPE_API_BASE_URL + prefix + suffix + postfix + secondPostfix,
            headers: {
                'Authorization': "Bearer " + STRIPE_SECRET_KEY
            },
            params:request.params["params"],
            success: function(httpResponse) 
            {
                //response text is a json dictionary
                response.success(httpResponse.text);
            },
            error: function(httpResponse) 
            {
                response.error(httpResponse.text);
            }
    });
});

使用上面的方法我可以创建单独的方法来执行我需要的大部分条带化任务。

这里是创建新卡并将其附加到客户的示例 Stripe Card creation API

+ (void)createCardFromToken:(NSString *)tokenId customerId:(NSString *)customerId completionHandler:(ELCardCompletionBlock)handler
{

    [ELStripe executeStripeCloudCodeWithMethod:@"POST" //I use post here because we are creating a card. POST would also be used for updating a customer/card or refunding a charge for example
                                        prefix:@"customers" //If you look at the documentation and the example URL I use "customers" here as the prefix
                                        suffix:customerId //The customerID is the suffix, this will be the customer you are going to add the card to
                                       postfix:@"cards" //I believe this is "sources" now
                                 secondPostfix:nil //Not needed for this URL
                                    parameters:@{
                                                 @"card":tokenId  //Only parameter is a tokenId, and I wrap this inside an NSDictionary
                                                 }
                             completionHandler:^(id jsonObject, NSError *error) {
                                 if (error)
                                 {
                                     //Handle the error code here

                                     handler(nil,rejectError);
                                     return;
                                 }
                                 //If no error stripe returns a dictionary containing the card information. You can use this information to create a card object if so desired.
                                 handler([ELCard cardFromDictionary:jsonObject],error);
                             }];
}
