Basic authentication scheme

The "Basic" HTTP authentication scheme is defined in RFC 7617, which transmits credentials as user ID/password pairs, encoded using base64.

Basic authentication is a simple authentication scheme built into the HTTP protocol. The client sends HTTP requests with the Authorization header that contains the word Basic word followed by a space and a base64-encoded string username:password .

CSharp example:

   HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(sendParam.address);
   request.ContinueTimeout = 88000;
   request.ContentType = "application/json; charset=utf-8";
   request.Accept = "application/json, text/javascript, */*";
   request.Method = "POST";
   String encoded = System.Convert.ToBase64String(System.Text.Encoding.GetEncoding("ISO-8859-1").GetBytes(UserName_Authotication + ":" + Password_Authontification));
   request.Headers.Add("Authorization", "Basic " + encoded);

   using (StreamWriter writer = new StreamWriter(request.GetRequestStream()))
   {
      writer.Write(strRequest);
   }
   WebResponse response = request.GetResponse();
   using ( Stream stream = response.GetResponseStream()){
                json = "";

                using (StreamReader reader = new StreamReader(stream))
                {
                    while (!reader.EndOfStream)
                    {
                        json += reader.ReadLine();
                    }
                }
	}

With Tls12 Security protocol

  using System;
  using System.IO;
  using System.Net;

  namespace Crawler
 {
     public class WebReader
    {

       private CredentialCache GetCredential(string url,string WebUserName,string WebPassword)
      {
        ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
        CredentialCache credentialCache = new CredentialCache();
        credentialCache.Add(new System.Uri(url), "Basic", new NetworkCredential(WebUserName,
             WebPassword));
        return credentialCache;
      }

      public string SendHttpReq(string sUrl,string WebUserName,string WebPassword)
     {
        var encoding = System.Text.Encoding.UTF8;

        string lcHtml = null;

        try
        {

            // *** Set properties
            var loHttp = (HttpWebRequest)WebRequest.Create(sUrl);

            loHttp.Timeout = 5350000;

            loHttp.Credentials = GetCredential(sUrl,WebUserName,WebPassword);
            loHttp.PreAuthenticate = true;

                // *** Retrieve request info headers
                using (var loWebResponse = (HttpWebResponse)loHttp.GetResponse())
                {
                    using (var responseStream = loWebResponse.GetResponseStream())
                    {

                        using (var loResponseStream = new StreamReader(loWebResponse.GetResponseStream(), encoding))
                        {

                            lcHtml = loResponseStream.ReadToEnd();
                            loResponseStream.Close();

                        }
                    }
                }
        } catch ( Exception ex)
        {
            Console.WriteLine(ex.Message);
        }
        return lcHtml;

      }
   }
}

JavaScript Example

	var UserName="myUserName";
	var password="myPassword";

	$.ajax({
		type: 'POST',
		url: 'myLink',
		headers: {
			"Authorization": "Basic " + btoa(UserName+":"+password);
		},
		success : function(data) {
			//Success block  
		},
		error: function (xhr,ajaxOptions,throwError){
			//Error block 
		},
	 });
