ios - Paytm sdk ios 集成以打开 Paytm 付款表格？

Question

在 iOS (Xcode 7) 中集成 Paytm sdk 2.1 并配置为进行支付。

我有一个表格，其中需要填写金额和其他字段，然后有一个付款按钮。

这是我正在使用的代码:

 //Step 1: Create a default merchant config object
    PGMerchantConfiguration *mc = [PGMerchantConfiguration defaultConfiguration];

    //Step 2: If you have your own checksum generation and validation url set this here. Otherwise use the default Paytm urls
    mc.checksumGenerationURL = @"generate checksum url";
    mc.checksumValidationURL =   @"checksum validation url";


    //Step 3: Create the order with whatever params you want to add. But make sure that you include the merchant mandatory params
    NSMutableDictionary *orderDict = [NSMutableDictionary new];
    //Merchant configuration in the order object
    orderDict[@"MID"] = @"abc1111"; 
    orderDict[@"CHANNEL_ID"] = @"WAP";
    orderDict[@"INDUSTRY_TYPE_ID"] = @"Education";
    orderDict[@"WEBSITE"] = @"companyname";
    //Order configuration in the order object
    orderDict[@"TXN_AMOUNT"] = @"100";
    orderDict[@"ORDER_ID"] = [Feepayment generateOrderIDWithPrefix:@"111"];
    orderDict[@"REQUEST_TYPE"] = @"DEFAULT";
    orderDict[@"CUST_ID"] = @"abc7777";

    PGOrder *order = [PGOrder orderWithParams:orderDict];

    //Step 4: Choose the PG server. In your production build dont call selectServerDialog. Just create a instance of the
    //PGTransactionViewController and set the serverType to eServerTypeProduction


    [PGServerEnvironment selectServerDialog:self.view completionHandler:^(ServerType type)
     {
         PGTransactionViewController *txnController = [[PGTransactionViewController alloc] initTransactionForOrder:order];

         //show title var
         UIView *mNavBar = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width,44)];
         mNavBar.backgroundColor = [UIColor grayColor];
         txnController.topBar = mNavBar;

         //Cancel button
         UIButton *mCancelButton = [[UIButton alloc] initWithFrame:CGRectMake(5, 2, 70, 40)];
         [mCancelButton setTitle:@"Cancel" forState:UIControlStateNormal];
         mCancelButton.titleLabel.textColor = PURPLE_COLOR;
         [mCancelButton setFont:[UIFont fontWithName:@"Helvetica-Bold" size:15.0]];
         txnController.cancelButton = mCancelButton;


         //add title
         UILabel *mTitleLabel = [[UILabel alloc] initWithFrame:CGRectMake(self.view.frame.size.width/2 - 10, 1, 100, 50)];
         [mTitleLabel setText:@"Payment"];
         [mTitleLabel setFont:[UIFont fontWithName:@"Helvetica-Bold" size:15.0]];
         mTitleLabel.textColor = [UIColor whiteColor];
         [mNavBar addSubview:mTitleLabel];

         if (type!=eServerTypeNone) {
             txnController.serverType = type;
             txnController.merchant = mc;
             txnController.loggingEnabled = YES;
             txnController.sendAllChecksumResponseParamsToPG = YES;
             txnController.delegate = self;
             [self showController:txnController];
         }

     }];

//show controller method
-(void)showController:(PGTransactionViewController *)controller {
    if (self.navigationController != nil)
        [self.navigationController pushViewController:controller animated:YES];
    else
        [self presentViewController:controller animated:YES
                         completion:^{

                         }];
}
//remove controller
-(void)removeController:(PGTransactionViewController *)controller {
    if (self.navigationController != nil)
        [self.navigationController popViewControllerAnimated:YES];
    else
        [controller dismissViewControllerAnimated:YES
                                       completion:^{
                                       }];
}
#pragma mark PGTransactionViewController delegate

- (void)didSucceedTransaction:(PGTransactionViewController *)controller
                     response:(NSDictionary *)response {
    DEBUGLOG(@"ViewController::didSucceedTransactionresponse= %@", response);
    NSString *title = [NSString stringWithFormat:@"Your order  was completed successfully. \n %@", response[@"ORDERID"]];
    [[[UIAlertView alloc] initWithTitle:title message:[response description] delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil] show];
    [self removeController:controller];
}

- (void)didFailTransaction:(PGTransactionViewController *)controller error:(NSError *)error response:(NSDictionary *)response {
    DEBUGLOG(@"ViewController::didFailTransaction error = %@ response= %@", error, response);
    if (response)
    {
        [[[UIAlertView alloc] initWithTitle:error.localizedDescription message:[response description] delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil] show];
    }
    else if (error)
    {
        [[[UIAlertView alloc] initWithTitle:@"Error" message:error.localizedDescription delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil] show];
    }
    [self removeController:controller];
}

- (void)didCancelTransaction:(PGTransactionViewController *)controller error:(NSError*)error response:(NSDictionary *)response {
    DEBUGLOG(@"ViewController::didCancelTransaction error = %@ response= %@", error, response);
    NSString *msg = nil;
    if (!error) msg = [NSString stringWithFormat:@"Successful"];
    else msg = [NSString stringWithFormat:@"UnSuccessful"];

    [[[UIAlertView alloc] initWithTitle:@"Transaction Cancel" message:msg delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil] show];
    [self removeController:controller];
}

- (void)didFinishCASTransaction:(PGTransactionViewController *)controller response:(NSDictionary *)response {
    DEBUGLOG(@"ViewController::didFinishCASTransaction:response = %@", response);


}

下面是使用登台直接显示此页面时的屏幕截图:

*注意 - 实际上我正在尝试暂存而不是生产。

当我执行时，它不会显示 Paytm 费用支付表格，而是直接显示带有交易 ID 的订单 ID 和金额。

当用户在表格中输入费用金额时，如何打开 Paytm 付款表格，然后它应该用额外的税计算金额，然后点击费用支付按钮，它应该打开 PAYTM 付款表格。

请帮助我解决这个问题(我已经逐步浏览了 PAYTM SDK 文档，但无法找到它)。谢谢。

重要:**就checksumGenerationURL 和checksumValidationURL 而言，我们需要创建它。最初我尝试使用 Paytm，但它无法正常工作，所以最终我们的服务器团队做到了，这是集成 Paytm 最重要​​的一点

最后，通过在产品上测试它并正常工作来解决。就暂存服务器而言，我猜 sdk 中有硬编码信息，所以希望在下一个版本的 PGSDK 中我们也可以在暂存服务器上测试它。

谢谢。

@Pradeep k ...非常感谢您的宝贵支持。
