How to Query REST API ?

> domain\username:password must be authorize to query to the REST API.
> For POST HttpRequest is content type and use charset=utf-8 to convert.
> For GET HttpRequest is Accept


POST:

Uri address = new Uri(@"https://xx.xx.xx.xx:xxxx/abc/config/anything/");
HttpWebRequest request = WebRequest.CreateDefault(address) as HttpWebRequest;
request.Method = "POST";
request.Headers["Authorization"] = "Basic " + 
Convert.ToBase64String(Encoding.Default.GetBytes(@"domain\username:password"));
request.ContentType = "application/vnd.com.cisco.ise.identity.guestuser.2.0+xml; charset=utf-8";
ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback(delegate { return true; });

//Inserting data 

string data="xml data";

byte[] bytes = Encoding.UTF8.GetBytes(data);
request.ContentLength = bytes.Length;
using (Stream requestStream = request.GetRequestStream())
{
  // Send the data.
   requestStream.Write(bytes, 0, bytes.Length);
  requestStream.Close();
 }


Get By Name:

string name="";

Uri address = new Uri(@"https://xx.xx.xx.xx:xxxx/abc/config/anything/name/" +name +" ");

HttpWebRequest request = WebRequest.CreateDefault(address) as HttpWebRequest;
request.Method = "GET";
request.Headers["Authorization"] = "Basic " + Convert.ToBase64String(Encoding.Default.GetBytes(@"domain\username:password"));
request.Accept = "application/vnd.com.cisco.ise.identity.guestuser.2.0+xml";
ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback(delegate { return true; });
       
using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
{
StreamReader reader = new StreamReader(response.GetResponseStream());
string s = reader.ReadToEnd();

}

Get All:

Uri address = new Uri(@"https://xx.xx.xx.xx:xxxx/abc/config/anything/ ");

HttpWebRequest request = WebRequest.CreateDefault(address) as HttpWebRequest;
request.Method = "GET";
request.Headers["Authorization"] = "Basic " + Convert.ToBase64String(Encoding.Default.GetBytes(@"domain\username:password"));
request.Accept = "application/vnd.com.cisco.ise.identity.guestuser.2.0+xml";
ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback(delegate { return true; });

StreamReader reader = new StreamReader(response.GetResponseStream());
string s = reader.ReadToEnd();
