获取Hash Mismatch付钱你Swift 3
我是Swift的新手，我正在快速整合PayUmoney IOS SDK，我遇到了麻烦当我在现场做它的显示哈希不匹配（哈希不匹配1）如果我在测试中它显示无效的商家密钥（无效密钥）我从2个星期到这里来了这么多的事情，并没有得到任何解决方案，这可以任何人帮助它会很棒。 以下是我的代码，谢谢你提前。
var params : PUMRequestParams = PUMRequestParams.shared() var utils : Utils = Utils() params.environment = PUMEnvironment.test; params.firstname = txtFldName.text; params.key = "bZf4AOjj"; params.merchantid = "5745303"; params.logo_url = ""; params.productinfo = "Product Info"; params.email = txtFldEmail.text; params.phone = ""; params.surl = "https://www.payumoney.com/mobileapp/payumoney/success.php"; params.furl = "https://www.payumoney.com/mobileapp/payumoney/failure.php"; if(params.environment == PUMEnvironment.test){ generateHashForProdAndNavigateToSDK() } else{ calculateHashFromServer() } // assign delegate for payment callback. params.delegate = self; } func generateHashForProdAndNavigateToSDK() -> Void { let txnid = params.txnid! let hashSequence : NSString = "\(params.key)|\(txnid)|\(params.amount)|\(params.productinfo)|\(params.firstname)|\(params.email)|||||||||||2uIsGhXWVw" as NSString let data :NSString = utils.createSHA512(hashSequence as String!) as NSString params.hashValue = data as String!; startPaymentFlow(); } // MARK:HASH CALCULATION func prepareHashBody()->NSString{ return "SHA-512key=\(params.key!)&amount=\(params.amount!)&txnid=\(params.txnid!)&productinfo=\(params.productinfo!)&email=\(params.email!)&firstname=\(params.firstname!)" as NSString; } func calculateHashFromServer(){ let config = URLSessionConfiguration.default // Session Configuration let session = URLSession(configuration: config) // Load configuration into Session let url = URL(string: "https://test.payumoney.com/payment/op/v1/calculateHashForTest")! var request = URLRequest(url: url) request.httpBody = prepareHashBody().data(using: String.Encoding.utf8.rawValue) request.httpMethod = "POST" let task = session.dataTask(with: request, completionHandler: { (data, response, error) in if error != nil { print(error!.localizedDescription) } else { do { if let json = try JSONSerialization.jsonObject(with: data!, options: []) as? [String: Any]{ print(json) let status : NSNumber = json["status"] as! NSNumber if(status.intValue == 0) { self.params.hashValue = json["result"] as! String! OperationQueue.main.addOperation { self.startPaymentFlow() } } else{ OperationQueue.main.addOperation { self.showAlertViewWithTitle(title: "Message", message: json["message"] as! String) } } } } catch { print("error in JSONSerialization") } } }) task.resume() } 你好Vinny做webview它为我工作。 之前我也使用过这个PayUmoney IOS SDK，但面对如此多的问题所以基于objective-c我做了这个，所以我认为它对你有用。 创建一个弱的var webview并创建类UIwebviewdelegate
class PayumoneyViewController: UIViewController, UIWebViewDelegate, UIAlertViewDelegate { @IBOutlet weak var Webview: UIWebView!
并且用于测试以下凭证
//test var merchantKey = "40747T" var salt = "ur salt" var PayUBaseUrl = "https://test.payu.in"
为了生活
//Production var merchantKey = “xxxxxx” var salt = “xxxxx” var PayUBaseUrl = "https://secure.payu.in" let productInfo = “Myapp” //It can be Project name or anything else let firstName = “Santoshi” //Details of user whose is purchasing order let email = “santoshi@app.com" //Details of user whose is purchasing order let phone = "xxxxxxxxx" //Details of user whose is purchasing order let sUrl = "www.google.com" //By this URL we match whether payment got success or failure let fUrl = "www.google.com" //By this URL we match whether payment got success or failure let service_provider = "payu_paisa" var txnid1: String! = "" //Its an unique id which can give order a specific order number. let totalPriceAmount = "1.0"
以上viewdidload就是这样的
override func viewWillAppear(_ animated: Bool) { super.viewWillAppear(true) initPayment() } override func viewWillDisappear(_ animated: Bool) { super.viewWillDisappear(true) }
在viewdidload中这样做
override func viewDidLoad() { super.viewDidLoad() Webview.delegate = self // Do any additional setup after loading the view. }
创建付款并生成哈希密钥
func initPayment() { txnid1 = “Myapp\(String(Int(NSDate().timeIntervalSince1970)))" //Generating Hash Key let hashValue = String.localizedStringWithFormat("%@|%@|%@|%@|%@|%@
||%@”,merchantKey,txnid1,totalPriceAmount,productInfo,firstName,email,salt) let hash = self.sha1(string: hashValue) let postStr = “txnid=”+txnid1+”&key=”+merchantKey+”&amount=”+totalPriceAmount+”&productinfo=”+productInfo+”&firstname=”+firstName+”&email=”+email+”&phone=”+phone+”&surl=”+sUrl+”&furl=”+fUrl+”&hash=”+hash+”&service_provider=”+service_provider let url = NSURL(string: String.localizedStringWithFormat(“%@/_payment”, PayUBaseUrl)) let request = NSMutableURLRequest(url: url! as URL) do { let postLength = String.localizedStringWithFormat(“%lu”,postStr.characters.count) request.httpMethod = “POST” request.setValue(“application/x-www-form-urlencoded”, forHTTPHeaderField: “Current-Type”) request.setValue(postLength, forHTTPHeaderField: “Content-Length”) request.httpBody = postStr.data(using: String.Encoding.utf8) Webview.loadRequest(request as URLRequest) } catch let error as NSError { print(error) } }
最后这样做
func sha1(string:String) -> String { let cstr = string.cString(using: String.Encoding.utf8) let data = NSData(bytes: cstr, length: string.characters.count) var digest = [UInt8](repeating: 0, count:Int(CC_SHA512_DIGEST_LENGTH)) CC_SHA512(data.bytes, CC_LONG(data.length), &digest) let hexBytes = digest.map { String(format: "%02x", $0) } return hexBytes.joined(separator: "") } func webViewDidFinishLoad(_ webView: UIWebView) { let requestURL = self.Webview.request?.url let requestString:String = (requestURL?.absoluteString)! if requestString.contains("https://www.payumoney.com/mobileapp/payumoney/success.php") { print("success payment done") }else if requestString.contains("https://www.payumoney.com/mobileapp/payumoney/failure.php") { print("payment failure") } } func webView(_ webView: UIWebView, didFailLoadWithError error: Error) { let requestURL = self.Webview.request?.url print("WebView failed loading with requestURL: \(requestURL) with error: \(error.localizedDescription) & error code: \(error)") if error._code == -1009 || error._code == -1003 { showAlertView(userMessage: "Please check your internet connection!") }else if error._code == -1001 { showAlertView(userMessage: "The request timed out.") } } func showAlertView(userMessage:String){ }
我遇到了同样的问题，我已经解决了这个问题。 在我的代码中，这一行生成可选值 – >让hashSequence：NSString =“（params.key！）|（txnid）|（params.amount！）|（params.productinfo！）|（params.firstname！）|（ params.email！）
||（params.merchantid！）“as NSString
从值中删除可选项。
