I'm using following code to get response from php script but it gives me javascript error response instead of script response.

C# Code:

C#

var request = (HttpWebRequest)WebRequest.Create("http://gujaratmovement.rf.gd/testc.php");

            var postData = "test=hello";
            var data = Encoding.ASCII.GetBytes(postData);

            request.Method = "POST";
            request.ContentType = "application/x-www-form-urlencoded";
            request.ContentLength = data.Length;

            using (var stream = request.GetRequestStream())
            {
                stream.Write(data, 0, data.Length);
            }

            var response = (HttpWebResponse)request.GetResponse();

            var responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();
            richTextBox1.Text = responseString;

Output response:

<html><body><script type="text/javascript" src="/aes.js" ></script><script>function toNumbers(d){var e=[];d.replace(/(..)/g,function(d){e.push(parseInt(d,16))});return e}function toHex(){for(var d=[],d=1==arguments.length&&arguments[0].constructor==Array?arguments[0]:arguments,e="",f=0;f<d.length;f++)e+=(16>d[f]?"0":"")+d[f].toString(16);return e.toLowerCase()}var a=toNumbers("f655ba9d09a112d4968c63579db590b4"),b=toNumbers("98344c2eee86c3994890592585b49f80"),c=toNumbers("b1d5801948be3fab1aaf846da47ba80f");document.cookie="__test="+toHex(slowAES.decrypt(c,2,a,b))+"; expires=Thu, 31-Dec-37 23:55:55 GMT; path=/"; location.href="http://gujaratmovement.rf.gd/testc.php?i=1";</script><noscript>This site requires Javascript to work, please enable Javascript in your browser or use a browser with Javascript support</noscript></body></html>

Solution 1

The site you're trying to scrape has added that Javascript block to prevent people from doing precisely what you appear to be trying to do - steal their content.

You will either need to talk to the people who run that site to see if there's another way your can access their content, or find another source.

The Site is mine and hosted on shared hosting. How do i disable it?

Change the code on your site to remove the redirection script, or add a specific end-point for your C# application that just returns the data you want.
