iOS Parse Stripe Integration

我对编程很新,我创建了一个应用程序来向客户收费,并希望存储他们的CC信息并在以后收费.我一直在浏览所有的教程和文档,我无法理解如何将其集成到我的应用程序中.我是否需要了解其他技术技能,例如Rest API,Curl,Ruby等才能进行此设置？所有指南和文档都指向了这个方向.我真的不明白GET / POST是什么以及它如何适合iOS Objective-C编程.

关于如何设置它的任何指导都将非常感激.我已经坚持了一段时间了.

解决方法

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,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",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);
            }];
        }
    }];
}

//Process payment using a customer to their active card. No token is required if customer exists with a card on record.
//*********Warning: This is the final step it will APPLY A CHARGE TO THE ACCOUNT.***************

-(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)
        {
            [self initSelfWithDictionary:object];
            NSLog(@"object:%@",object);
        }
        handler(self,error);
    }];
}

//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)
     {
         if (!error)
         {
             [self initSelfWithDictionary:object];
         }
         handler(self,error);
     }];
}
+ (NSDictionary *)dictionaryFromSTPChargeForProccessingUsingCard:(STPCharge *)charge
{
    NSMutableDictionary *dictionary = [NSMutableDictionary dictionary];
    dictionary[@"amount"] = charge.amountInCents;
    dictionary[@"currency"] = charge.currency;
    dictionary[@"card"] = charge.token.tokenId;
    return dictionary;
}
+ (NSDictionary *)dictionaryFromSTPChargeForProccessingUsingCustomer:(STPCharge *)charge
{
    NSMutableDictionary *dictionary = [NSMutableDictionary dictionary];
    dictionary[@"amount"] = charge.amountInCents;
    dictionary[@"currency"] = charge.currency;
    dictionary[@"customer"] = charge.customer.identifier;
    return dictionary;
}

用于向客户/令牌收费的云代码：

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