Simple C# .NET 4.5 HTTPClient Request Using Basic Auth and Proxy

 In this article,  I am explaining, How to get response using HttpClient Class.

HttpClient Class

Namespace:System.Net.Http

Assembly:System.Net.Http.dll

using System;

using System.Text;

using System.Threading.Tasks;

using System.Net.Http;

using System.Net;

using System.Web.Script.Serialization;

 

namespace HTTP_Test

{

  class program

  {

    static void Main()

    {

      Task t = new Task(HTTP_GET);

      t.Start();

      Console.ReadLine();

    }

 

    static async void HTTP_GET()

    {

      var TARGETURL = "http://en.wikipedia.org/";

 

      HttpClientHandler handler = new HttpClientHandler()

      {

        Proxy = new WebProxy("http://127.0.0.1:8888"),

        UseProxy = true,

      };

 

      Console.WriteLine("GET: + " + TARGETURL);

      // ... Use HttpClient.           

      HttpClient client = new HttpClient(handler);

 

      var byteArray = Encoding.ASCII.GetBytes("username:password1234");

      client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Basic", Convert.ToBase64String(byteArray));

 

      HttpResponseMessage response = await client.GetAsync(TARGETURL);

      HttpContent content = response.Content;

 

      // ... Check Status Code                               

      Console.WriteLine("Response StatusCode: " + (int)response.StatusCode);

 

      // ... Read the string.

      string result = await content.ReadAsStringAsync();

 

      // ... Display the result.

      if (result != null && result.Length >= 50)

      {

        Console.WriteLine(result.Substring(0, 50) + "...");

      }

    }

 

    static void GetResponseJson(string sJsonString)

    {

      string inputJson = (new JavaScriptSerializer()).Serialize(sJsonString);

      HttpClient client = new HttpClient();

      HttpContent inputContent = new StringContent(inputJson, Encoding.UTF8, "application/json");

      var byteArray = Encoding.ASCII.GetBytes("username:password1234");

      client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Basic", Convert.ToBase64String(byteArray));

 

      HttpResponseMessage response = client.PostAsync("https://testing.com" + "/GetClient", inputContent).Result;

    }

  }

}
