HTTP Digest-MD5 Authentication Testing with httpbin.org

See more HTTP Examples

The URL https://httpbin.org/digest-auth/auth/user/passwd is password protected with user="user" and password="passwd". It requires Digest-MD5 authentication. Chilkat will automatically handle Digest-MD5 authentication as required by the server response. In this case, however, the server will fail the authentication unless a Cookie is included in the request. The cookie can have any name and any value. (Yes, this is ridiculous, and many developers have probably spent countless hours assuming their Digest-MD5 implementations were incorrect.) Java

import com.chilkatsoft.*;

public class ChilkatExample {

  static {
    try {
        System.loadLibrary("chilkat");
    } catch (UnsatisfiedLinkError e) {
      System.err.println("Native code library failed to load.\n" + e);
      System.exit(1);
    }
  }

  public static void main(String argv[])
  {
    // This example assumes the Chilkat HTTP API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    CkHttp http = new CkHttp();

    http.put_Login("user");
    http.put_Password("passwd");

    // Add a cookie to satisfy httpbin.org's desire for cookies..
    // Otherwise, it will fail the perfectly valid Digest-MD5 authentication.
    http.SetRequestHeader("Cookie","something=\"something\"");

    String strResponse = http.quickGetStr("https://httpbin.org/digest-auth/auth/user/passwd");
    if (http.get_LastMethodSuccess() == false) {
        System.out.println(http.lastErrorText());
        return;
        }

    System.out.println(strResponse);

    int status = http.get_LastStatus();
    System.out.println("response status code = " + status);

    // The output of this program is:
    // 
    // 	{ 
    // 	  "authenticated": true, 
    // 	  "user": "user"
    // 	} 
    // 
    // 	response status code = 200
  }
