ios - 当我在 IOS 中集成 CCAvenue Payment Gate way 时，我收到 Exe_Bad_Access(code=1 address=0X38)

Question

我按照以下步骤集成了无耻的CCAvenue GateWay

步骤:-

我有我的商家 ID 和访问代码(url、ip)。

1. 我正在调用我的服务器来获取 RSA key 参数(access_code、order_id)

//我的服务器已经在 CCAvenue 服务器中注册 2.我的服务器调用Avenue获取RSA key

3.my服务器转发RSA key

4.一旦我得到了，我将删除多余的行“\n”，双引号“”--“”，和“\”

// removing double quates


 NSString * newReplacedString2 = [rsaKey stringByReplacingOccurrencesOfString:@"\"" withString:@""]; 

//removing /n in the key


  NSString * newReplacedString = [newReplacedString2 stringByReplacingOccurrencesOfString:@"\\n" withString:@""];


 //removing / in the key

 NSString * newReplacedString1 = [newReplacedString stringByReplacingOccurrencesOfString:@"\\" withString:@""]; 

5.我将该键放在

之间

rsaKey = [NSString stringWithFormat:@"-----BEGIN PUBLIC KEY-----\n%@\n-----END PUBLIC KEY-----\n",newReplacedString1];

//*******//***//****//**//  output   //*******//***//****//**//

   -----BEGIN PUBLIC KEY-----

    -----END PUBLIC KEY-----

我正在使用CCTool加密金额和价格

NSString *myRequestString = [NSString stringWithFormat:@"amount=%@&currency=%@",amount,currency];(2,INR)
CCTool *ccTool = [[CCTool alloc] init];
NSString *encVal = [ccTool encryptRSA:myRequestString key:rsaKey];

因为我正在获取Exe_Bad_Acess

RSA *rsa = PEM_read_bio_RSA_PUBKEY(bufio, NULL,NULL,NULL);

RSA 出现错误。

如何解决这个问题。请帮助我。!!

嗨，谢谢大家的支持，我终于解决了我的问题。

一旦您从服务器获得 rsa key ，您需要删除新行“\n”、斜杠“\”和双引号“\””

这里我们需要将其转换为ba64加密格式的输入。

https://gist.github.com/superwills/5415344#file-openssl-rsa-encryption-sample-L154

你需要将我们的字符串转换得完全相同， 1. 每行“字符串”必须为64个字符宽。 2.必须以换行符结束

我正在更新我的代码。对我来说，它工作正常。

  NSString *rsaKey = [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding];

//NSString *rsaKey = [[NSString alloc] initWithData:数据编码:NSASCIIStringEncoding];

        NSLog(@"%@",rsaKey);

//rsaKey = [rsaKey stringByTrimmingCharactersInSet:[NSCharacterSet newlineCharacterSet]]; //NSLog(@"%@",rsaKey);

        // removing double quates
        NSString * newReplacedString2 = [rsaKey stringByReplacingOccurrencesOfString:@"\"" withString:@""];

        NSLog(@"%@",rsaKey);

        //removing \n in the key
        NSString * newReplacedString = [newReplacedString2 stringByReplacingOccurrencesOfString:@"\\n" withString:@""];

        NSLog(@"%@",rsaKey);


        //removing \ in the key
        NSString * newReplacedString1 = [newReplacedString stringByReplacingOccurrencesOfString:@"\\" withString:@""];
        NSLog(@"%@",newReplacedString1);


        NSString * abc = [NSString stringWithFormat:@"%@", newReplacedString1];
        NSMutableString *sss=[NSMutableString new];
        int j=(int)([abc length]/63);
        for (int i=0; i<=j; i++) {
            int k= i*63;
            NSString * newString;
            if (i != j) {
                newString = [abc substringWithRange:NSMakeRange(k,63)];
                NSLog(@"%lu",(unsigned long)newString.length);
                newString=[NSString stringWithFormat:@"%@",newString];
            }else{
                newString = [abc substringWithRange:NSMakeRange(k,[abc length]-k)];
                NSLog(@"%lu",(unsigned long)newString.length);
                if (newString.length !=0)
                    newString=[NSString stringWithFormat:@"%@",newString];
            }
            if (newString.length !=0)
                [sss appendString:[NSString stringWithFormat:@"%@\n",newString]];
        }
        NSLog(@"%@",sss);


        rsaKey = [NSString stringWithFormat:@"-----BEGIN PUBLIC KEY-----\n%@-----END PUBLIC KEY-----\n",sss];
        NSLog(@"%@",rsaKey);

        //Encrypting Card Details
            NSString *myRequestString = [NSString stringWithFormat:@"amount=%@&currency=%@",amount,currency];
            CCTool *ccTool = [[CCTool alloc] init];


        NSLog(@"emcrpted data  skfjsf jakdfhjklfhjk%@",[ccTool encryptRSA:myRequestString key:rsaKey]);






            Happy Coding. :)
