我正在尝试在我的应用程序中集成 payu 货币支付网关。Payumoney 收集所有信息并完成交易并返回到我自定义的 url 网页。

我的问题是如何从payu货币网关成功交易后获取响应码？

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 *productInfo = @"App Products Info ";
NSString *firstname = dataMoney.usrName;
NSString *email = dataMoney.usrEmail;
NSString *phone = dataMoney.usrMobile;

NSString *surl = @"https://dl.dropboxusercontent.com/s/dtnvwz5p4uymjvg/success.html";
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
[request setHTTPMethod:@"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Current-Type"];
[request setHTTPBody:postData];

[web_view_PayU loadRequest:request];
