CCAvenue：“错误!!! 解密申请请求“
我正在尝试将CCAvenue支付网关集成到我在swift4中开发的iOS应用程序中。 我正进入（状态
“错误!!!解密应用程序请求时出现问题”
我检查了答案： https ： //stackoverflow.com/a/37327122/3548469，但我的情况没有运气。
这是我从文档中尝试过的
private func gettingRsaKey(completion: @escaping (_ success: Bool, _ object: AnyObject?) -> ()){ let serialQueue = DispatchQueue(label: "serialQueue", qos: .userInitiated) serialQueue.sync { print("access_code=\(CC_AVENUE_ACCESSKEY)") print("order_id=\(self.orderId)") self.rsaKeyDataStr = "access_code=\(CC_AVENUE_ACCESSKEY)&order_id=\(self.orderId)" let requestData = self.rsaKeyDataStr.data(using: String.Encoding.utf8) guard let urlFromString = URL(string: CC_AVENUE_RSAURL) else{ return } var urlRequest = URLRequest(url: urlFromString) urlRequest.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "content-type") urlRequest.httpMethod = "POST" urlRequest.httpBody = requestData let session = URLSession(configuration: URLSessionConfiguration.default) print("session",session) session.dataTask(with: urlRequest as URLRequest) { (data, response, error) -> Void in if let response = response as? HTTPURLResponse, 200...299 ~= response.statusCode{ guard let data = data else{ print("No value for data") completion(false, "Not proper data for RSA Key" as AnyObject?) return } print("data :: ",data) completion(true, data as AnyObject?) } else{ completion(false, "Unable to generate RSA Key please check" as AnyObject?) } }.resume() } } var request: NSMutableURLRequest? private func encyptCardDetails(data: Data){ guard let rsaKeytemp = String(bytes: data, encoding: String.Encoding.ascii) else{ print("No value for rsaKeyTemp") return } rsaKey = rsaKeytemp rsaKey = self.rsaKey.trimmingCharacters(in: CharacterSet.newlines) rsaKey = "-----BEGIN PUBLIC KEY-----\n\(self.rsaKey)\n-----END PUBLIC KEY-----\n" print("rsaKey :: ",rsaKey) let myRequestString = "amount=\(amount)¤cy=\(getCurrency())" let ccTool = CCTool() var encVal = ccTool.encryptRSA(myRequestString, key: rsaKey) encVal = CFURLCreateStringByAddingPercentEscapes( nil, encVal! as CFString, nil, "!*'();:@&=+$,/?%#[]" as CFString, CFStringBuiltInEncodings.UTF8.rawValue) as String? let urlAsString = "https://secure.ccavenue.com/transaction/initTrans" let encryptedStr = String(format:"merchant_id=%@&order_id=%@&redirect_url=%@&cancel_url=%@&enc_val=%@&access_code=%@", CC_AVENUE_MERCHANTID, self.orderId, CC_AVENUE_REDIRECTURL, CC_AVENUE_REDIRECTURL, encVal!,CC_AVENUE_ACCESSKEY) print("access_code=\(CC_AVENUE_ACCESSKEY)") print("order_id=\(self.orderId)") let myRequestData = encryptedStr.data(using: String.Encoding.utf8) request = NSMutableURLRequest(url: URL(string: urlAsString)! as URL, cachePolicy: NSURLRequest.CachePolicy.reloadIgnoringCacheData, timeoutInterval: 30) request?.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "content-type") request?.setValue(urlAsString, forHTTPHeaderField: "Referer") request?.httpMethod = "POST" request?.httpBody = myRequestData print("\n\n\nwebview :: ",request?.url as Any) print("\n\n\nwebview :: ",request?.description as Any) print("\n\n\nwebview :: ",request?.httpBody?.description as Any) print("\n\n\nwebview :: ",request?.allHTTPHeaderFields! as Any) let session = URLSession(configuration: URLSessionConfiguration.default) print("session",session) session.dataTask(with: request! as URLRequest) { (data, response, error) -> Void in if let response = response as? HTTPURLResponse, 200...299 ~= response.statusCode{ guard let data = data else{ print("No value for data") return } DispatchQueue.main.async { self.viewWeb.loadRequest(self.request! as URLRequest) } print("data :: ",data) }else{ print("into else") showAlertWithTitleWithMessage(message: "Unable to load webpage currently, Please try again later.") } }.resume() } 我能够生成无法进一步的RSA密钥。
注意*
我有真实帐户，我使用访问代码和帐户AccessCode的商家密钥 ，orderId与用于生成RSA密钥的相同。
嘿，我遇到了同样的问题。 这是因为新的CCAvenue SDK。 用于加载页面请求的CCAvenue流程分为三个步骤。
1）我们从服务器获得RSA密钥。
2）我们使用此RSA密钥加密订单详细信息并创建Web请求。
3）在webview中打开请求。
当步骤1和步骤3之间没有任何延迟时，问题就出现了。为了克服这个问题，新的SDK引入了创建延迟的新步骤。
1）我们从服务器获得RSA密钥。
2）我们使用此RSA密钥加密订单详细信息并创建Web请求。
3）CCAvenue在此引入了一个新的URLRequest，仅用于在步骤1和4中进行延迟
4）在webview中打开请求。
这适用于大多数时间，但是当步骤3以毫秒完成时或者在步骤1和步骤4中没有延迟或非常小的延迟时它失败。
因此，此处的解决方法是在步骤1和步骤4中创建手动延迟。
所以将你的function改为：
private func encyptCardDetails(data: Data){ guard let rsaKeytemp = String(bytes: data, encoding: String.Encoding.ascii) else{ print("No value for rsaKeyTemp") return } rsaKey = rsaKeytemp rsaKey = self.rsaKey.trimmingCharacters(in: CharacterSet.newlines) rsaKey = "-----BEGIN PUBLIC KEY-----\n\(self.rsaKey)\n-----END PUBLIC KEY-----\n" print("rsaKey :: ",rsaKey) let myRequestString = "amount=\(amount)¤cy=\(getCurrency())" let ccTool = CCTool() var encVal = ccTool.encryptRSA(myRequestString, key: rsaKey) encVal = CFURLCreateStringByAddingPercentEscapes( nil, encVal! as CFString, nil, "!*'();:@&=+$,/?%#[]" as CFString, CFStringBuiltInEncodings.UTF8.rawValue) as String? let urlAsString = "https://secure.ccavenue.com/transaction/initTrans" let encryptedStr = String(format:"merchant_id=%@&order_id=%@&redirect_url=%@&cancel_url=%@&enc_val=%@&access_code=%@", CC_AVENUE_MERCHANTID, self.orderId, CC_AVENUE_REDIRECTURL, CC_AVENUE_REDIRECTURL, encVal!,CC_AVENUE_ACCESSKEY) print("access_code=\(CC_AVENUE_ACCESSKEY)") print("order_id=\(self.orderId)") let myRequestData = encryptedStr.data(using: String.Encoding.utf8) request = NSMutableURLRequest(url: URL(string: urlAsString)! as URL, cachePolicy: NSURLRequest.CachePolicy.reloadIgnoringCacheData, timeoutInterval: 30) request?.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "content-type") request?.setValue(urlAsString, forHTTPHeaderField: "Referer") request?.httpMethod = "POST" request?.httpBody = myRequestData print("\n\n\nwebview :: ",request?.url as Any) print("\n\n\nwebview :: ",request?.description as Any) print("\n\n\nwebview :: ",request?.httpBody?.description as Any) print("\n\n\nwebview :: ",request?.allHTTPHeaderFields! as Any) let session = URLSession(configuration: URLSessionConfiguration.default) print("session",session) session.dataTask(with: request! as URLRequest) { (data, response, error) -> Void in if let response = response as? HTTPURLResponse, 200...299 ~= response.statusCode{ guard let data = data else{ print("No value for data") return } // Create the delay here DispatchQueue.main.asyncAfter(deadline: .now()+1.0, execute: { self.viewWeb.loadRequest(self.request! as URLRequest) } print("data :: ",data) }else{ print("into else") showAlertWithTitleWithMessage(message: "Unable to load webpage currently, Please try again later.") } }.resume() }
