Persistent Fingerprints Using Files

[34892002]

Hi,
I need to save the generated fingerprint to a file such that I could load it back later to the browser.
Is there a way to dump and load the fingerprint to/from a file?

thanks.

The code written like this is invalid.

if os.path.exists(fingerprint_path):
        with open(fingerprint_path, 'r', encoding='utf-8') as f:
            data = json.load(f)

        fingerprint = Fingerprint(
            screen=ScreenFingerprint(**data['screen']),
            navigator=NavigatorFingerprint(**data['navigator']),
            headers=data['headers'],
            videoCodecs=data['videoCodecs'],
            audioCodecs=data['audioCodecs'],
            pluginsData=data['pluginsData'],
            battery=data['battery'],
            videoCard=VideoCard(**data['videoCard']) if data.get('videoCard') else None,
            multimediaDevices=data['multimediaDevices'],
            fonts=data['fonts'],
            mockWebRTC=data.get('mockWebRTC', False),
            slim=data.get('slim', False)
        )
    else:
        fingerprint = fg.generate()
        fingerprint_dict = json.loads(fingerprint.dumps())
        with open(fingerprint_path, 'w', encoding='utf-8') as f:
            json.dump(fingerprint_dict, f, ensure_ascii=False, indent=4)

you can use pickle.dump and pickle.load

[xmmw]

json dump does not support dataclass
