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.) C#

//  This example assumes the Chilkat HTTP API to have been previously unlocked.
//  See Global Unlock Sample for sample code.

Chilkat.Http http = new Chilkat.Http();

http.Login = "user";
http.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.LastMethodSuccess == false) {
    Debug.WriteLine(http.LastErrorText);
    return;
}

Debug.WriteLine(strResponse);

int status = http.LastStatus;
Debug.WriteLine("response status code = " + Convert.ToString(status));

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