使用Stripe + Parse和雲代碼存儲信用卡

[英]Store credit card using Stripe + Parse with cloud code

我正在嘗試將用戶的信用卡存儲到條帶中。 制作完令牌后,我嘗試將用戶的令牌保存到Stripe作為客戶。 但是我沒有找到問題的答案,我只需要將卡存儲到已經存在的用戶即可。

我嘗試使用方法Stripe.Customers.update,但是它存儲新卡,如果用戶有,則刪除“默認”卡。 並使用Stripe.Customers.create方法使用新卡創建新客戶,但我需要存儲在特定用戶中。

雲代碼:

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代碼:

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)")
        }
    }

我嘗試了幾種參數來按需存儲卡,但是總是收到錯誤消息“收到未知參數”

任何人都知道如何在不刪除或創建新客戶的情況下存儲卡?

解析的帶區實現不盡如人意。 在許多情況下,您必須使用HTTPRequest來執行Parse不提供的條帶功能。

對於這些情況,我使用以下iOS方法和CloudCode執行我所有的帶區HTTPRequest。 遵循條紋CURL API文檔時,編碼非常容易。 然后,我構建此方法來執行大多數條帶化任務,例如IE創建/更新/刪除客戶,卡,費用等。

首先,根據要獲取,創建/更新或刪除條帶對象,為它提供一個方法,即GET,POST,DELETE。

然后,我將可選的pre / suf / postfix組合提供給它,以創建一個url。

創建的示例URL:

在此處輸入圖片說明

最后,在創建卡並將其添加到客戶的情況下,我給它提供參數,這只需要是一個包含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);
    }];
}

執行的雲代碼:

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,我可以創建單獨的方法來執行我需要的大多數條紋任務。

這是一個示例,它將創建一個新卡並將其附加到客戶的Stripe Card創建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);
                             }];
}
