在iOS中使用Stripe验证信用卡
我开始将Stripe整合到我正在制作的iOS应用程序中，并且我需要验证卡信息。
我试过了：
#pragma mark - My Actions
- (IBAction)buyButtonTapped:(id)sender {
//Populate STPCard property
self.stripeCard = [[STPCard alloc]init];
self.stripeCard.name = self.txtFieldCardHolderName.text;
self.stripeCard.number = self.txtFieldCardNumber.text;
self.stripeCard.cvc = self.txtFieldCardCvc.text;
self.stripeCard.expMonth = [self.selectedMonth integerValue];
self.stripeCard.expYear = [self.selectedYear integerValue];
//Validate Customer info
if ([self validateCustomerInfo]) {
[self performStripeOperation];
}
}
-(BOOL)validateCustomerInfo{
//Create Alert
UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"Please, try again!"
message:@"Please, enter all required information."
preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *action = [UIAlertAction actionWithTitle:@"OK"
style:UIAlertActionStyleDefault
handler:^(UIAlertAction * _Nonnull action) {
//Add some action
}];
//Add its action
[alert addAction:action];
//Validate text fields
if (self.txtFieldCardHolderName.text == 0 || self.txtFieldCardNumber.text == 0 || self.txtFieldCardExpDate.text == 0 || self.txtFieldCardCvc.text == 0) {
[self presentViewController:alert animated:true completion:nil];
return NO;
}
//Validate card number, CVC, expMonth, expYear
NSError *error = nil;
[self.stripeCard validateCardReturningError:&error];
//3
if (error) {
alert.message = [error localizedDescription];
[self presentViewController:alert animated:true completion:nil];
return NO;
}
return YES;
}
我在StackOverflow上检查了其他几个问题，并且每个人似乎都使用了validateCardReturningError方法，并且已将其弃用于iOS9。
Xcode抱怨并要求我改用STPCardValidator。
任何人都可以帮助我使用STPCardValidator进行卡片验证的一个示例？
我注意到我也可以使用下面的Class方法：
[STPCardValidator validationStateForNumber:self.txtFieldCardNumber.text validatingCardBrand:true];
但我不确定如何在我的validateCustomerInfo方法中使用它。
- (IBAction)buyButtonTapped:(id)sender{
param = [[STPCardParams alloc]init];
param.number = txt_cc_no.text;
param.cvc = txt_cc_cvvno.text;
param.expMonth =[self.selectedMonth integerValue];
param.expYear = [self.selectedYear integerValue];
if ([self validateCustomerInfo]) {
[self performStripeOperation];
}
}
- (BOOL)validateCustomerInfo {
//2. Validate card number, CVC, expMonth, expYear
[STPCardValidator validationStateForExpirationMonth:[self.selectedMonth stringValue]];
[STPCardValidator validationStateForExpirationYear:[self.selectedYear stringValue] inMonth:[self.selectedMonth stringValue]];
if ([txt_cc_type.text isEqualToString:@"visa"]) {
[STPCardValidator validationStateForCVC:txt_cc_cvvno.text cardBrand:STPCardBrandVisa];
[STPCardValidator validationStateForNumber:txt_cc_no.text validatingCardBrand:STPCardBrandVisa];
}
else if ([txt_cc_type.text isEqualToString:@"MasterCard"]){
[STPCardValidator validationStateForCVC:txt_cc_cvvno.text cardBrand:STPCardBrandMasterCard];
[STPCardValidator validationStateForNumber:txt_cc_no.text validatingCardBrand:STPCardBrandMasterCard];
}
else if ([txt_cc_type.text isEqualToString:@"American Express"]){
[STPCardValidator validationStateForCVC:txt_cc_cvvno.text cardBrand:STPCardBrandAmex];
[STPCardValidator validationStateForNumber:txt_cc_no.text validatingCardBrand:STPCardBrandAmex];
}
else if ([txt_cc_type.text isEqualToString:@"Discover"]){
[STPCardValidator validationStateForCVC:txt_cc_cvvno.text cardBrand:STPCardBrandDiscover];
[STPCardValidator validationStateForNumber:txt_cc_no.text validatingCardBrand:STPCardBrandDiscover];
}
else if ([txt_cc_type.text isEqualToString:@"Diners Club"]){
[STPCardValidator validationStateForCVC:txt_cc_cvvno.text cardBrand:STPCardBrandDinersClub];
[STPCardValidator validationStateForNumber:txt_cc_no.text validatingCardBrand:STPCardBrandDinersClub];
}
else if ([txt_cc_type.text isEqualToString:@"JCB"]){
[STPCardValidator validationStateForCVC:txt_cc_cvvno.text cardBrand:STPCardBrandJCB];
[STPCardValidator validationStateForNumber:txt_cc_no.text validatingCardBrand:STPCardBrandJCB];
}
else if ([txt_cc_type.text isEqualToString:@"Unknown"]){
[STPCardValidator validationStateForCVC:txt_cc_cvvno.text cardBrand:STPCardBrandUnknown];
[STPCardValidator validationStateForNumber:txt_cc_no.text validatingCardBrand:STPCardBrandUnknown];
}
return YES;
}
- (void)performStripeOperation {
[[STPAPIClient sharedClient] createTokenWithCard:param
completion:^(STPToken *token, NSError *error) {
if (error) {
// [self handleError:error];
NSLog(@"ERRRRR = %@",error);
UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"Please try again"
message:[NSString stringWithFormat:@"%@",error.localizedDescription]
delegate:nil
cancelButtonTitle:@"OK"
otherButtonTitles:nil];
[alert show];
} else {
//when credit card details is correct code here
}
}];
}
Swift 2.1版本的Femina的回答。 注意：validateCardType（）是一个正则表达式函数，如果你也想这样，你可以在这里找到它如何检测基于数字的信用卡类型？
func validateCustomerInfo() -> Bool {
// Validate card number, CVC, expMonth, expYear
STPCardValidator.validationStateForExpirationMonth(self.expMonth.text!)
STPCardValidator.validationStateForExpirationYear(self.expYear.text!, inMonth: self.expMonth.text!)
if (self.validateCardType(creditCardField.text!) == "Visa") {
STPCardValidator.validationStateForCVC(self.securityField.text!, cardBrand: STPCardBrand.Visa)
STPCardValidator.validationStateForNumber(self.creditCardField.text!, validatingCardBrand: true)
}
else if (self.validateCardType(creditCardField.text!) == "MasterCard") {
STPCardValidator.validationStateForCVC(self.securityField.text!, cardBrand: STPCardBrand.MasterCard)
STPCardValidator.validationStateForNumber(self.creditCardField.text!, validatingCardBrand: true)
}
else if (self.validateCardType(creditCardField.text!) == "American Express") {
STPCardValidator.validationStateForCVC(self.securityField.text!, cardBrand: STPCardBrand.Amex)
STPCardValidator.validationStateForNumber(self.creditCardField.text!, validatingCardBrand: true)
}
else if (self.validateCardType(creditCardField.text!) == "Discover") {
STPCardValidator.validationStateForCVC(self.securityField.text!, cardBrand: STPCardBrand.Discover)
STPCardValidator.validationStateForNumber(self.creditCardField.text!, validatingCardBrand: true)
}
else if (self.validateCardType(creditCardField.text!) == "Diners Club") {
STPCardValidator.validationStateForCVC(self.securityField.text!, cardBrand: STPCardBrand.DinersClub)
STPCardValidator.validationStateForNumber(self.creditCardField.text!, validatingCardBrand: true)
}
else if (self.validateCardType(creditCardField.text!) == "JCB") {
STPCardValidator.validationStateForCVC(self.securityField.text!, cardBrand: STPCardBrand.JCB)
STPCardValidator.validationStateForNumber(self.creditCardField.text!, validatingCardBrand: true)
}
else if (self.validateCardType(creditCardField.text!) == "Unknown") {
STPCardValidator.validationStateForCVC(self.securityField.text!, cardBrand: STPCardBrand.Unknown)
STPCardValidator.validationStateForNumber(self.creditCardField.text!, validatingCardBrand: true)
}
return true
}
这样做的最简单的方法，而不是做所有的计算。
您可以使用STPCardPalms实例作为参数的STPCardValidator的validationStateForCard方法。
- (IBAction)buyButtonTapped:(id)sender{
param = [[STPCardParams alloc]init];
param.number = txt_cc_no.text;
param.cvc = txt_cc_cvvno.text;
param.expMonth =[self.selectedMonth integerValue];
param.expYear = [self.selectedYear integerValue];
if ([self validateCustomerInfo]) {
[self performStripeOperation];
}
}
func validateCustomerInfo() -> Bool {
// Validate card number, CVC, expMonth, expYear
return STPCardValidator.validationStateForCard(param) == .Valid
}
