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

#include <C_CkHttp.h>

void ChilkatSample(void)
    {
    HCkHttp http;
    const char *strResponse;
    int status;

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

    http = CkHttp_Create();

    CkHttp_putLogin(http,"user");
    CkHttp_putPassword(http,"passwd");

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

    strResponse = CkHttp_quickGetStr(http,"https://httpbin.org/digest-auth/auth/user/passwd");
    if (CkHttp_getLastMethodSuccess(http) == FALSE) {
        printf("%s\n",CkHttp_lastErrorText(http));
        CkHttp_Dispose(http);
        return;
    }

    printf("%s\n",strResponse);

    status = CkHttp_getLastStatus(http);
    printf("response status code = %d\n",status);

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


    CkHttp_Dispose(http);
