GetAuthCredentials not getting called windowless browser

[ramjana]

Hi Experts!
Trust all in good health

I have a C++ application where we are trying to integrate with Microsoft OneDrive. The application has a windowless popout browser that loads the OneDrive file picker.

The integration works well when we try to login to MS without proxy. But I does not work with proxy enabled. I have attached the fiddler trace. One thing I have noticed is I do not see GetAuthCredentials function getting called when we have the proxy enabled. I am using cef 85.3.6(it used to work fine in cef 73).
I tried setting up the flag

Code: Select all

command_line->AppendSwitchWithValue("disable-features", "NetworkService");

. But still it does not work with proxy enabled.

Also It works when we render the MS url on a normal cefbrowser (not windowless).

Kindly suggest if I could be missing anything.

You cannot disable the network service anymore.

What does your GetAuthCredentials implementation look like? Did you update the signature? Do you have override set on your methods to catch signature changes?

Thank you amaitland for the reply.

Below is how the function signature and definition looks like,

Code: Select all

bool GetAuthCredentials(CefRefPtr<CefBrowser> browser,
                                const CefString& origin_url,
                                bool isProxy,
                                const CefString& host,
                                int port,
                                const CefString& realm,
                                const CefString& scheme,
                                CefRefPtr<CefAuthCallback> callback) override;

Code: Select all

bool ClientHandler::GetAuthCredentials(CefRefPtr<CefBrowser> browser,
                                           const CefString& origin_url,
                                           bool isProxy,
                                           const CefString& host,
                                           int port,
                                           const CefString& realm,
                                           const CefString& scheme,
                                           CefRefPtr<CefAuthCallback> callback)
    {
        if (isProxy)
        {
            mScfProxyHandler->getAuthCredentials(host, callback);
            return true;
        }
        else
        {
            if (const auto lockedDelegate = delegate_.lock())
            {
                lockedDelegate->OnAuthenticationCredentialsRequired(host, callback);
                return true;
            }
            return false;
        }
    }

Is your GetAUthCredentials implementation triggered when isProxy is false? Say visit http://httpbin.org/#/Auth/get_basic_aut ... ___passwd_

M85 is no longer supported, are you able to test with a supported version? https://bitbucket.org/chromiumembedded/ ... -supported

Testing with cefclient is also something I'd look at https://github.com/chromiumembedded/cef ... er.cc#L735 t

[ramjana]

Yes, GetAUthCredentials implementation is triggered when isProxy is false. What I noticed is, It does not gets called when I try to render the url on a windowless browser. For a windowless browser, it does not trigger GetAUthCredentials implementation at all.

Code: Select all

// Window info
        CefWindowInfo window_info;
window_info.SetAsWindowless(NULL);

Tried on the latest CEF version(CEF 87.1.12). Still the same issue. Is this know to anyone specifically with MS graph API?
I am using a window less browser
