(Objective-C) HTTP Digest-MD5 Authentication Testing with httpbin.org

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.)

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

CkoHttp *http = [[CkoHttp alloc] init];

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" value: @"something=\"something\""];

NSString *strResponse = [http QuickGetStr: @"https://httpbin.org/digest-auth/auth/user/passwd"];
if (http.LastMethodSuccess == NO) {
    NSLog(@"%@",http.LastErrorText);
    return;
}

NSLog(@"%@",strResponse);

int status = [http.LastStatus intValue];
NSLog(@"%@%d",@"response status code = ",status);

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