我必须在我的iOS应用程序中集成PayUMoney支付网关。他们没有适用于iOS的SDK。因此,我必须在webview中加载一些Web URL以进行付款。我的参数是
I have to integrate PayUMoney payment gateway in my iOS app. They don't have SDK for iOS. So I have to load some web URL in webview for the payment. My parameters are
int i = arc4random() % 9999999999;
NSString *strHash = [self createSHA512:[NSString stringWithFormat:@"%d%@",i,[NSDate date]]];// Generatehash512(rnd.ToString() + DateTime.Now);
NSString *txnid1 = [strHash substringToIndex:20];
NSLog(@"tnx1 id %@",txnid1);
NSString *key = @"JBZaLc";
NSString *amount = @"1000";
NSString *productInfo = @"Nice product";
NSString *firstname = @"Mani";
NSString *email = @"mani.ingenius@gmail.com";
NSString *phone = @"1234566";
NSString *surl = @"www.google.com";
NSString *furl = @"www.google.com";
NSString *serviceprovider = @"payu_paisa";
NSString *action = @"https://test.payu.in/_payment";
NSString *hashValue = [NSString stringWithFormat:@"%@|%@|%@|%@|%@|%@|udf1|udf2|udf3|udf4|udf5||||||salt",key,txnid1,amount,productInfo,firstname,email];
NSString *hash = [self createSHA512:hashValue];
NSDictionary *parameters = [NSDictionary dictionaryWithObjects:[NSArray arrayWithObjects:txnid1,key,amount,productInfo,firstname,email,phone,surl,furl,hash,serviceprovider,action, nil] forKeys:[NSArray arrayWithObjects:@"txnid",@"key",@"amount",@"productinfo",@"firstname",@"email",@"phone",@"surl",@"furl",@"hash",@"service_provider",@"action", nil]];
我必须使用POST方法和我的测试网址( https:// test.payu.in/_payment
)并需要传递参数。我有字典中的键和值的所有参数(参数)。所以我尝试了以下代码
I have to use POST method with my test URL (https://test.payu.in/_payment
) and need to pass parameters. I have all parameters with key and value in dictionary("parameters"). So I tried following code
NSData *dataValue = [self getPropertiesAsData:parameters];
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"https://test.payu.in/_payment"]];
// Create a mutable copy of the immutable request and add more headers
NSMutableURLRequest *mutableRequest = [request mutableCopy];
[mutableRequest setHTTPMethod: @"POST"];
[mutableRequest setHTTPBody: dataValue];
request = [mutableRequest copy];
[_webviewSample loadRequest:request];
-(NSData *)getPropertiesAsData :(NSDictionary *)dict{
NSMutableData *body = [NSMutableData postData];
[dict enumerateKeysAndObjectsUsingBlock:^(id key, id obj, BOOL *stop) {
[body addValue:[obj stringByReplacingOccurrencesOfString:@" " withString:@"%20"] forKey:key];
}];
return body;
}
-(NSString *)createSHA512:(NSString *)string
{
const char *cstr = [string cStringUsingEncoding:NSUTF8StringEncoding];
NSData *data = [NSData dataWithBytes:cstr length:string.length];
uint8_t digest[CC_SHA512_DIGEST_LENGTH];
CC_SHA512(data.bytes, data.length, digest);
NSMutableString* output = [NSMutableString stringWithCapacity:CC_SHA512_DIGEST_LENGTH * 2];
for(int i = 0; i < CC_SHA512_DIGEST_LENGTH; i++)
[output appendFormat:@"%02x", digest[i]];
return output;
}
但是当我运行它时,它会显示缺少强制参数tnxid。但是我已经传递了你可以在参数字典中看到的tnxid。如果我正确传递了所有内容,那么结果将是用户可以选择银行详细信息等的网页,我必须在我的网页视图中加载它。
But when I run this, it says "Mandatory parameter tnxid is missing". But I have passed the tnxid which you can see in parameters dictionary. If I pass everything correctly then result will be the webpage where user can select bank details, etc that I have to load it in my web view.
请帮我查找我做错了什么或我该怎么做才能得到正确的结果。
Please help me to find what I did wrong or what I should do to get correct result.
推荐答案
我成功找到了答案。我的工作代码列在下面
I found answer successfully. My working code is listed below
int i = arc4random() % 9999999999;
NSString *strHash = [self createSHA512:[NSString stringWithFormat:@"%d%@",i,[NSDate date]]];// Generatehash512(rnd.ToString() + DateTime.Now);
NSString *txnid1 = [strHash substringToIndex:20];
NSLog(@"tnx1 id %@",txnid1);
NSString *key = @"JBZaLc";
NSString *amount = @"1000";
NSString *productInfo = @"Nice product";
NSString *firstname = @"Mani";
NSString *email = @"mani.ingenius@gmail.com";
NSString *phone = @"1234566";
NSString *surl = @"www.google.com";
NSString *furl = @"www.google.com";
NSString *serviceprovider = @"payu_paisa";
NSString *hashValue = [NSString stringWithFormat:@"%@|%@|%@|%@|%@|%@|||||||||||GQs7yium",key,txnid1,amount,productInfo,firstname,email];
NSString *hash = [self createSHA512:hashValue];
NSDictionary *parameters = [NSDictionary dictionaryWithObjects:[NSArray arrayWithObjects:txnid1,key,amount,productInfo,firstname,email,phone,surl,furl,hash,serviceprovider
, nil] forKeys:[NSArray arrayWithObjects:@"txnid",@"key",@"amount",@"productinfo",@"firstname",@"email",@"phone",@"surl",@"furl",@"hash",@"service_provider", 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"]]];
[request setHTTPMethod:@"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Current-Type"];
[request setHTTPBody:postData];
[_webviewSample loadRequest:request];
然后使用的功能
-(NSString *)createSHA512:(NSString *)string
{
const char *cstr = [string cStringUsingEncoding:NSUTF8StringEncoding];
NSData *data = [NSData dataWithBytes:cstr length:string.length];
uint8_t digest[CC_SHA512_DIGEST_LENGTH];
CC_SHA512(data.bytes, (CC_LONG)data.length, digest);
NSMutableString* output = [NSMutableString stringWithCapacity:CC_SHA512_DIGEST_LENGTH * 2];
for(int i = 0; i < CC_SHA512_DIGEST_LENGTH; i++)
[output appendFormat:@"%02x", digest[i]];
return output;
}
