Authorized.Net payment gateway implementation

Copy paste following code to implement payment gateway using c#.net:

 String post_url = “https://test.authorize.net/gateway/transact.dll“;

            Hashtable post_values = new Hashtable();

            //the API Login ID and Transaction Key must be replaced with valid values
            post_values.Add(“x_login”, “6zz6m5N4Et”);
            post_values.Add(“x_tran_key”, “9V9wUv6Yd92t27t5”);

            post_values.Add(“x_delim_data”, “TRUE”);
            post_values.Add(“x_delim_char”, ‘|’);
            post_values.Add(“x_relay_response”, “FALSE”);

            post_values.Add(“x_type”, “AUTH_CAPTURE”);
            post_values.Add(“x_method”, “CC”);
            post_values.Add(“x_card_num”, “378282246310005”);
            post_values.Add(“x_exp_date”, “0809”);

            post_values.Add(“x_amount”, “99999.00”);
            post_values.Add(“x_description”, “Sample Transaction”);

            post_values.Add(“x_first_name”, “John”);
            post_values.Add(“x_last_name”, “Doe”);
            post_values.Add(“x_address”, “1234 Street”);
            post_values.Add(“x_state”, “WA”);
            post_values.Add(“x_zip”, “98004”);
            // Additional fields can be added here as outlined in the AIM integration
            // guide at: http://developer.authorize.net

            // This section takes the input fields and converts them to the proper format
            // for an http post.  For example: “x_login=username&x_tran_key=a1B2c3D4”
            String post_string = “”;
            foreach(DictionaryEntry field in post_values)
            {
                post_string += field.Key + “=” + field.Value + “&”;
            }
            post_string = post_string.TrimEnd(‘&’);
           
            // create an HttpWebRequest object to communicate with Authorize.net
            HttpWebRequest objRequest = (HttpWebRequest)WebRequest.Create(post_url);
            objRequest.Method = “POST”;
            objRequest.ContentLength = post_string.Length;
            objRequest.ContentType = “application/x-www-form-urlencoded”;

            // post data is sent as a stream
            StreamWriter myWriter  = null;
            myWriter = new StreamWriter(objRequest.GetRequestStream());
            myWriter.Write(post_string);
            myWriter.Close();

            // returned values are returned as a stream, then read into a string
            String post_response;
            HttpWebResponse objResponse = (HttpWebResponse)objRequest.GetResponse();
            using (StreamReader responseStream = new StreamReader(objResponse.GetResponseStream()) )
            {
                post_response = responseStream.ReadToEnd();
                responseStream.Close();
            }

            // the response string is broken into an array
            // The split character specified here must match the delimiting character specified above
            Array response_array = post_response.Split(‘|’);

            // the results are output to the screen in the form of an html numbered list.
            resultSpan.InnerHtml += “<OL> \n”;
            foreach (string value in response_array)
            {
                resultSpan.InnerHtml += “<LI>” + value + “&nbsp;</LI> \n”;
            }
            resultSpan.InnerHtml += “</OL> \n”;
            // individual elements of the array could be accessed to read certain response
            // fields.  For example, response_array[0] would return the Response Code,
            // response_array[2] would return the Response Reason Code.
            // for a list of response fields, please review the AIM Implementation Guide

Grab webpage contents using javascript

You can read/fetch web page contents using  javascript.  The page should be available on the live URL. 

Please find the code below:

<script type=”text/javascript”>
    var PageNm;
    var XmlHttpObj;
    var requestURL = ‘getServerTime.aspx’;
    var is_ie = (navigator.userAgent.indexOf(‘MSIE’) >= 0) ? 1 : 0;
    var is_ie5 = (navigator.appVersion.indexOf(“MSIE 5.5”) != -1) ? 1 : 0;
    var is_opera = ((navigator.userAgent.indexOf(“Opera6”) != -1) || (navigator.userAgent.indexOf(“Opera/6”) != -1)) ? 1 : 0;
    //netscape, safari, mozilla behave the same???
    var is_netscape = (navigator.userAgent.indexOf(‘Netscape’) >= 0) ? 1 : 0;  

 

    function GetResponse() {

        var xhr = CreateXmlHttpObj();
        // Page URL needs to be written here
        xhr.open(“GET”, “Web Page URL”, true);
        xhr.onreadystatechange = function() {
            if (xhr.readyState == 4) {
                if (xhr.status == 200) {
                    statusDiv = document.getElementById(“stats”);

                    alert(xhr.responseText);
                } else {
                    alert(‘error!’);
                }
            }
        };
        xhr.send(null);
    }

    function CreateXmlHttpObj() {
        // try creating for IE (note: we don’t know the user’s browser type here, just attempting IE first.)
        try {
            if (is_ie) {
                //The object to create depends on version of IE
                //If it isn’t ie5, then default to the Msxml2.XMLHTTP object
                var strObjName = (is_ie5) ? ‘Microsoft.XMLHTTP’ : ‘Msxml2.XMLHTTP’;

                //Attempt to create the object
                try {

                    XmlHttpObj = new ActiveXObject(strObjName);
                    //XmlHttpObj.onreadystatechange = handler;
                }
                catch (e) {
                    //Object creation errored
                    alert(‘IE detected, but object could not be created. Verify that active scripting and activeX controls are enabled’);
                    return;
                }
            }
            else if (is_opera) {
                //Opera has some issues with xmlHttp object functionality
                alert(‘Opera detected. The page may not behave as expected.’);
                return;
            }
            else {
                // Mozilla | Netscape | Safari
                XmlHttpObj = new XMLHttpRequest();
               
            }

 
        }
        catch (e) {
            try {
                XmlHttpObj = new ActiveXObject(“Microsoft.XMLHTTP”);
            }
            catch (oc) {
                XmlHttpObj = null;
            }
        }
        // if unable to create using IE specific code then try creating for Mozilla (FireFox)
        if (!XmlHttpObj && typeof XMLHttpRequest != “undefined”) {
            XmlHttpObj = new XMLHttpRequest();
        }

        return XmlHttpObj;
    }
