iOS Parse Stripe Integration

Parse的条带API并不像它应该的那样完整.它本身不包含许多功能,但可以通过HTTP请求完成.我必须学习一点Javascript和HTTP请求以获得许多功能.当然,你的第一直觉应该告诉你不要在任何设备上存储CC号码!只要您有用户输入CC编号,立即获得一个令牌,然后就是您需要使用的全部内容.

幸运的条纹使您能够节省客户,并将CC附加到客户,然后在未来再次获得CC编号时向该客户收费.Parse的api无法处理向客户添加CC,因此我自己添加了该功能.

因此,步骤1和2使用Parse的API生成客户,并使用Parse的API再次从他们输入的CC信息生成令牌.如果您需要有关此方面的帮助,请告知我们所需的云代码.

步骤3向客户添加CC.我正在使用自定义Customer对象,但您真正需要的主要是条形customerId,我的代码中是customer.identifier,CC中的tokenID,在我的例子中是token.tokenId.响应将是带有卡信息的JSON字符串,我将其转换为字典,然后从字典中创建STPCard.我还展示了如何从客户中删除卡.

iOS代码:

    +(void)addToken:(STPToken *)token toCustomerId:(NSString *)customerId completionHandler:(PFIdResultBlock)block
{
    [PFCloud callFunctionInBackground:@"stripeUpdateCustomer" withParameters:@{@"customerId":customerId,@"data":@{@"card":token.tokenId}} block:block];
}

+ (void)removeCard:(STPCard *)card FromCustomer:(ELCustomer *)customer completion:(STPCardDeletionBlock)handler
{
    if (!customer ||!customer.identifier || !card || !card.identifier || !handler) [NSException raise:@"RequiredParameter" format:@"Required Parameter Missing for deleting card from customer"];

    [PFCloud callFunctionInBackground:@"stripeDeleteCardFromCustomer" withParameters:@{@"cardId":card.identifier,@"customerId":customer.identifier} block:^(id object, NSError *error)
    {
            NSDictionary *dict = nil;
            NSError *jsonError = nil;

            if (object && [object isKindOfClass:[NSString class]] && !error) {
                dict = [NSJSONSerialization JSONObjectWithData:[object dataUsingEncoding:NSUTF8StringEncoding] options:kNilOptions error:&jsonError];
            }
            if (!jsonError && dict) {
                handler(dict[@"id"],[dict[@"deleted"] boolValue],error);
            }
            else if(jsonError) handler(nil,NO,jsonError);
            else handler(nil,NO,error);
    }];
}

需要云代码:

Parse.Cloud.define("stripeUpdateCustomer", function(request, response) 
{
        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); 
            }
        }
    );
});

Parse.Cloud.define("stripeDeleteCardFromCustomer", function(request, response) 
{
        Stripe.initialize(STRIPE_SECRET_KEY);
        Parse.Cloud.httpRequest({
                method:"DELETE",
                //STRIPE_SECRET_KEY will be your stripe secrect key obviously, this is different from the public key that you will use in your iOS/Android side.
                // STRIPE_API_BASE_URL = 'api.stripe.com/v1'
                url: "https://" + STRIPE_SECRET_KEY + ':@' + STRIPE_API_BASE_URL + "/customers/" + request.params.customerId + "/cards/" + request.params.cardId,
                success: function(httpResponse) {
                response.success(httpResponse.text);
                },
                error: function(httpResponse) {
                response.error('Request failed with response code ' + httpResponse.status);
                }
        });
});

用于向客户或令牌收取费用的iOS代码通知字典中所需的参数是以美分而非美元,货币,然后是客户或tokenId的金额.请注意,客户可以拥有多张信用卡,但其中一张是活动信用卡.有效卡是在向客户收费时将收取的卡:

//Will attempt to charge customer, if no customer exists, or it fails to charge the custoemr it will attempt to charge a card token directly;
//*********Warning: This is the final step it will APPLY A CHARGE TO THE ACCOUNT.***************

-(void)processChargeThroughStripeWithCompletionHandler:(STPChargeCompletionHandler)handler
{
    if (![self validForCardProcessing] && ![self validForCustomerProcessing]) {
        handler(nil,[NSError errorWithDomain:MY_ERROR_DOMAIN code:elErrorCodeNoCustomerOrTokenID userInfo:[NSDictionary dictionary]]);
        return;
    }
    [self processChargeThroughStripeUsingCustomerWithCompletionHandler:^(STPCharge *charge, NSError *error)
    {
        if (!error) handler(charge,error);
        else{
            [self processChargeThroughStripeUsingCardWithCompletionHandler:^(STPCharge *charge, NSError *error) {
                handler(charge, error);
            }];
        }
    }];
}

-(void)processChargeThroughStripeUsingCustomerWithCompletionHandler:(STPChargeCompletionHandler)handler
{
    if (!self.validForCustomerProcessing)

        handler(self,[NSError errorWithDomain:MY_ERROR_DOMAIN code:elErrorCodeNoCustomerID userInfo:[NSDictionary dictionary]]);
        return;
    }
    [PFCloud callFunctionInBackground:@"chargeToken" withParameters:[STPCharge dictionaryFromSTPChargeForProccessingUsingCustomer:self] block:^(id object, NSError *error)
    {
        if (!error)
        {

            NSLog(@"object:%@",object);
        }

    }];
}

//Process payment using a token that is attached to the charge, when complete self will be updated with the new charge information
//*********Warning: This is the final step it will APPLY A CHARGE TO THE ACCOUNT.***************

-(void)processChargeThroughStripeUsingCardWithCompletionHandler:(STPChargeCompletionHandler)handler
{
    if (!self.validForCardProcessing)
    {
        handler(self,[NSError errorWithDomain:MY_ERROR_DOMAIN code:elErrorCodeNoTokenID userInfo:[NSDictionary dictionary]]);
        return;
    }
    [PFCloud callFunctionInBackground:@"chargeToken" withParameters:[STPCharge dictionaryFromSTPChargeForProccessingUsingCard:self] block:^(id object, NSError *error)

         }
         handler(self,error);

    return dictionary;
}

    dictionary[@"amount"] = charge.amountInCents;

    return dictionary;

用于向客户/令牌收费的云代码:

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