Question

User1323099333 posted

Hi,

I have a requirement where I need to update the time stamp by consuming the RESTFUL service and performing the POST / PUT operation from ASP.Net.

 my Restful service url appears simlar to below one in which we will be passing userid and update_by values:

" https://testservice.com/My_partners?action=confirm_contact&userid=AAA0001&update_by=AAA0001 "

I have googled and got some posts which speaks about how to make a call to restful services. Below are the links

http://devlicio.us/blogs/derik_whittaker/archive/2009/02/14/posting-data-to-a-rest-service-using-c.aspx

But I couldn't understand how exaclty the value's are being passed in to the service.

Can some one let me know, where / what changes need to be done to make above code (in links0 fit to call above service.

Thanks In Advance

Venugopal.

Hi All,

I have written below code to update data using service and getting  error. Can some one please help?

 

string coreURL = "https://testservice.com/My_partners?action=confirm_contact&userid=AAA0001&update_by=AAA0001";

            string strURL = " https://testservice.com/My_partners?action=confirm_contact";

            string userid = " AAA0001";

            //byte[] dataByte = Encoding.UTF8.GetBytes("&&userid="+userid);

           

 

            HttpWebRequest POSTRequest = (HttpWebRequest)WebRequest.Create(strURL);

            //Method type

            POSTRequest.Method = "PUT";

            // Data type - message body coming in xml

            POSTRequest.ContentType = "application/x-www-form-urlencoded";

            POSTRequest.KeepAlive = false;

            POSTRequest.Timeout = 5000;

            //Content length of message body

            

 

            // Get the request stream

            Stream POSTstream = POSTRequest.GetRequestStream();

            // Write the data bytes in the request stream

            byte[] dataByte = Encoding.UTF8.GetBytes("&userid=" + userid);

            //POSTRequest.ContentLength = dataByte.Length;

            POSTstream.Write(dataByte, 0, dataByte.Length);

 

            dataByte = Encoding.UTF8.GetBytes("&update_by=" + userid);

           // POSTRequest.ContentLength = dataByte.Length;

            POSTstream.Write(dataByte, 0, dataByte.Length);

            POSTstream.Close();

 

            //Get response from server

            HttpWebResponse POSTResponse = (HttpWebResponse)POSTRequest.GetResponse();

            StreamReader reader =

              new StreamReader(POSTResponse.GetResponseStream(), Encoding.UTF8);

            Console.WriteLine("Response");

            Console.WriteLine(reader.ReadToEnd().ToString());
