Question

Hi,
I have developed an application which needs payment gateway. I have already worked on \"Paypal\". It was successful and now i need to integrate another payment gate

Answer 1

I have followed all the steps of Sagar Sukode and integrated CCAvenue SUCCESSFULLY.

If anyone need CCWEBVIEWCONTROLER in swift 2.3 :-

In ViewDidLoad :

    let rsaKey = getRsaKeyForCCAvenue()

    //Encrypting Card Details
    let myRequestString = "amount=\(AMOUNT)¤cy=\(CURRENCY)"

    let ccTool = CCTool()

    var encVal = ccTool .encryptRSA(myRequestString, key: rsaKey)

    let charset = NSCharacterSet(charactersInString: "!*'();:@&=+$,/?%#[]").invertedSet
    encVal = encVal.stringByAddingPercentEncodingWithAllowedCharacters(charset)

    //Preparing for a webview call
    let urlAsString = TRANS_URL

    let encryptedStr = "\(KEY_MERCHANT_ID)=\(MERCHANT_ID)&\(KEY_ORDER_ID)=\(ORDER_ID)&\(KEY_REDIRECT_URL)=\(REDIRECT_URL)&\(KEY_CANCEL_URL)=\(CANCEL_URL)&\(KEY_ENC_VAL)=\(encVal)&\(KEY_CC_ACCESS_CODE)=\(CC_ACCESS_CODE)&\(KEY_BILLING_NAME)=""&\(KEY_BILLING_ADDRESS)=""&\(KEY_BILLING_ZIP)=""&\(KEY_BILLING_CITY)=""&\(KEY_BILLING_STATE)=""&\(KEY_BILLING_COUNTRY)=""&\(KEY_BILLING_TEL)=""&\(KEY_BILLING_EMAIL)="""

    let myRequestData = encryptedStr.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)

    let request = NSMutableURLRequest(URL: NSURL(string: urlAsString)!)

    request.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "content-type")

    request.setValue("https://secure.ccavenue.com/", forHTTPHeaderField: "Referer")

    request.HTTPMethod = "POST"

    request.HTTPBody = myRequestData

    ccWebView .loadRequest(request)

Method To get rsaKey :

    func getRsaKeyForCCAvenue() -> String {

    //Getting RSA Key
    let rsaKeyDataStr = "\(KEY_CC_ACCESS_CODE)=\(CC_ACCESS_CODE)&\(KEY_ORDER_ID)=\(ORDER_ID)"

    let requestData = rsaKeyDataStr.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)

    let rsaRequest = NSMutableURLRequest(URL: NSURL(string: RSA_KEY_URL)!)

    rsaRequest .setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "content-type")

    rsaRequest.HTTPMethod = "POST"

    rsaRequest.HTTPBody = requestData

    let rsaKeyData: NSData? = try? NSURLConnection.sendSynchronousRequest(rsaRequest, returningResponse: nil)

    var rsaKey =  NSString(data: rsaKeyData!, encoding: NSASCIIStringEncoding)

    let strNewRSA = rsaKey as! String

    let range: Range = strNewRSA.rangeOfString("<")!
    let index: Int = strNewRSA.startIndex.distanceTo(range.startIndex)

    rsaKey = strNewRSA.substringToIndex(range.startIndex)

    rsaKey = rsaKey?.stringByTrimmingCharactersInSet(NSCharacterSet.newlineCharacterSet())

    rsaKey = "-----BEGIN PUBLIC KEY-----\n\(rsaKey!)\n-----END PUBLIC KEY-----\n"

    return rsaKey as! String
}

Web View Delegate method to read the response :

    func webViewDidFinishLoad(webView: UIWebView) {

    let webString = webView.request?.URL?.absoluteString
    if (webString! as NSString).containsString("PaymentCCAvenue/ReturnAPI") {

        let html = webView .stringByEvaluatingJavaScriptFromString("document.documentElement.outerHTML")          
        if (html! as NSString).containsString("Success") {
        }
        else if (html! as NSString).containsString("Failure") {  
        }
        else {
        }
    }

}

Just check for the response strings from the back end developers to add conditions in webViewDidFinishLoad.
