Usage

Initialization

On initialization visualCaptcha function requires a Session session object as first argument:

from visualcaptcha import Session, Captcha
visualCaptcha = Captcha( Session(session) )
# Optional arguments: visualCaptcha = Captcha( Session(session, namespace), assetsPath, defaultImages, defaultAudios )

Where:

• session is a required shared session object, where correct and option values are stored for later verification in the backend
• namespace is an optional argument. Defaults to 'visualcaptcha' and you can use it to use more than one visualCaptcha in the same page
• assetsPath is an optional argument. Defaults to the full path of './assets'.
• defaultImages is an optional parameter. Defaults to the array inside of ./assets/images.json. The path key is relative to ./assets/images/
• defaultAudios is an optional parameter. Defaults to the array inside of ./assets/audios.json. The path key is relative to ./assets/audios/

visualCaptcha.Captcha attributes

• session, Session object — An object that will have a reference for the session object. It will have the following keys inside visualCaptcha key: images, audios, validImageOption, and validAudioOption.

• imageOptions, list — All the image options. These can be easily overwritten with defaultImages when initializing Captcha. By default, they're populated using the ./assets/images.json file.

• audioOptions, list — All the audio options. These can be easily overwritten with defaultAudios when initializing Captcha. By default, they're populated using the ./assets/audios.json file.

• getValidAudioOption: ( self ) — Get the current validAudioOption.
• validateImage: ( self, sentOption ) — Validate the sent image value (sentOption) with the validImageOption.
• validateAudio: ( self, sentOption ) — Validate the sent audio value (sentOption) with the validAudioOption.
• getImageOptions: ( self ) — Return generated image options.
• getImageOptionAtIndex: ( self, index ) — Return generated image option at given index.
• getAudioOption: ( self ) — Alias for getValidAudioOption.
• getAllImageOptions: ( self ) — Return all the image options.
