我正在尝试在我的应用中集成payu money支付网关。 Payumoney收集所有信息并完成交易并返回我自定义的网址页面。
我的问题是如何在从payu money网关成功交易后获得响应代码？
int i = arc4random() % 9999999999;
NSString *strHash = [self createSHA512:[NSString stringWithFormat:@"%d%@",i,[NSDate date]]];
NSString *txnid1 = [strHash substringToIndex:20];
NSLog(@"tnx1 id %@",txnid1);
// NSString *key = @"JBZaLc";
// NSString* salt = @"GQs7yium";
NSString *key = @"gtKFFx";
NSString* salt = @"eCwWELxi";
NSString *amount = dataMoney.usrAmount;

NSString *furl = @"https://dl.dropboxusercontent.com/s/z69y7fupciqzr7x/furlWithParams.html";
NSString *hashValue = [NSString stringWithFormat:@"%@|%@|%@|%@|%@|%@|||||||||||%@",key,txnid1,amount,productInfo,firstname,email,salt];
NSString *hash = [self createSHA512:hashValue];
NSDictionary *parameters = [NSDictionary dictionaryWithObjects:[NSArray arrayWithObjects:txnid1,key,amount,productInfo,firstname,email,phone,surl,furl,hash, nil] forKeys:[NSArray arrayWithObjects:@"txnid",@"key",@"amount",@"productinfo",@"firstname",@"email",@"phone",@"surl",@"furl",@"hash", nil]];
__block NSString *post = @"";
[parameters enumerateKeysAndObjectsUsingBlock:^(id key, id obj, BOOL *stop) {
if ([post isEqualToString:@""]) {
post = [NSString stringWithFormat:@"%@=%@",key,obj];
}else{
post = [NSString stringWithFormat:@"%@&%@=%@",post,key,obj];
}
}];
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:@"%lu",(unsigned long)[postData length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:[NSString stringWithFormat:@"https://test.payu.in/_payment"]]];
// change URL for live
