Sending REST requests from code

By sending requests to the Kentico REST service, you can get data from the system or manipulate pages and objects.

The following example demonstrates how to send REST requests using server-side code. The sample code is incomplete — you need to perform the following according to your requirements:

  • integrate the request sending into your custom logic or application
  • supply the required values (HTTP method, request URL and data)
  • process the response data
  • ensure exception handling
C# example
using System;
using System.Web;
using System.Net;
using System.IO;
using System.Text;

...

string httpMethod; // "GET", "POST", "PUT" or "DELETE"
string requestUrl; // The URL of the REST request (base URL + resource path)
string requestData; // Data for POST or PUT requests

string responseDescription; // Stores the description of the response status
string responseData; // Stores data retrieved by the request

// Creates the REST request
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(requestUrl);

// Sets the HTTP method of the request
request.Method = httpMethod;

// Authorizes the request using Basic authentication
request.Headers.Add("Authorization: Basic YWRtaW5pc3RyYXRvcjo=");

// Submits data for POST or PUT requests
if (request.Method == "POST" || request.Method == "PUT")
{
	request.ContentType = "text/xml";

	Byte[] bytes = Encoding.GetEncoding("utf-8").GetBytes(requestData);
	request.ContentLength = bytes.Length;

	using (Stream writeStream = request.GetRequestStream())
	{
		writeStream.Write(bytes, 0, bytes.Length);
	}
}

// Gets the REST response
HttpWebResponse response = (HttpWebResponse)request.GetResponse();

// Stores the description of the response status
responseDescription = (Int32)response.StatusCode + " - " + response.StatusDescription;

// Gets the response data
using (Stream responseStream = response.GetResponseStream())
{
	if (responseStream != null)
		using (StreamReader reader = new StreamReader(responseStream))
		{
			responseData = HttpUtility.HtmlEncode(reader.ReadToEnd());
		}
}
