PayUMoney支付网关问题

我必须在我的iOS应用中集成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

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]];

我必须将POST方法与我的测试网址（https://test.payu.in/_payment）一起使用，并且需要传递参数。我在字典中包含键和值的所有参数（＆＃34;参数＆＃34;）。所以我尝试了以下代码

 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，它会说＆＃34;强制参数tnxid缺失＆＃34;。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，我必须在我的网络视图中加载它。

请帮助我找到我做错了什么或者我该怎么做才能得到正确的结果。

我成功找到了答案。我的工作代码列在下面

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];

然后使用函数

-(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;
}

最后我解决了关于 PayU India （不是payU，payU和payUindia与提及之间存在细微差别）整合的问题（上面的代码适用于payU Money帮助很多） 下载github Repo here

您只需要删除一个额外的参数，即service_provider，其值为payu_paisa。 

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 = @"YOURKEY";
    NSString *salt = @"YOURSALTKEY";

    NSString *amount = @"100";
    NSString *productInfo = @"Niceproduct";
    NSString *firstname = @"Deepak";
    NSString *email = @"iphonemaclover@gmail.com";
    NSString *phone = @"9212138007";
    NSString *surl = @"www.google.com";
    NSString *furl = @"www.google.com";


    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"]]];
    [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];

编辑：如何处理URL付款是否成功

-(void)webViewDidFinishLoad:(UIWebView *)webView{
        if (web_view_PayU.isLoading)
        return;
    NSURL *requestURL = [[web_view_PayU request] URL];

    NSLog(@"requestURL=%@",requestURL);

    NSString *getStringFromUrl=[NSString stringWithFormat:@"%@",requestURL];

    if ([getStringFromUrl isEqualToString:@"https://test.payu.in/yoursucessurladdedhere "]||[getStringFromUrl isEqualToString:@"https://secure.payu.in/yoursucessurladdedhere "])
    {
       //SUCCESS ALERT
       //jump to place order API

    }
   else if ([getStringFromUrl isEqualToString:@"https://test.payu.in/yourfailureurladdedhere "]||[getStringFromUrl isEqualToString:@"https://secure.payu.in/yourfailureurladdedhere"])
    {
        // FAIL ALERT
        UIAlertView *alert=[[UIAlertView alloc]initWithTitle:@"Sorry!" message:@"Your Order Not Successfull!" delegate:self cancelButtonTitle:nil otherButtonTitles:@"OK", nil];
        alert.tag=2222;

        [alert show];
    }

}

Recently, we have done some modifications in test environment due to which test key-JBZaLc and salt-GQs7yium will not work anymore.

In order to test the gateway using a test key and salt, kindly follow these steps:
1 - Go on https://test.payumoney.com
2 - Sign up as a merchant - use any of your valid email ids - kindly do not use a random email id.
3 - Complete the "Business Details"  - you may use PAN no. ABCDE1234F and DOB - 01/04/1990

对于swift版本

1）导入桥接标题

**导入CommonCrypto / CommonDigest.h **

2）之后

func sha512Hex( string: String) -> String {
    var digest = [UInt8](repeating: 0, count: Int(CC_SHA512_DIGEST_LENGTH))
    if let data = string.data(using: String.Encoding.utf8) {
        let value =  data as NSData
        CC_SHA512(value.bytes, CC_LONG(data.count), &digest)

    }
    var digestHex = ""
    for index in 0..<Int(CC_SHA512_DIGEST_LENGTH) {
        digestHex += String(format: "%02x", digest[index])
    }

    return digestHex
}

3）安装pod PlugNPlay

4）按照步骤提供PlugNPlay
