Answer 1

使用https://plone.org/products/quintagroup.formlib.captcha解决

from mypackage import myMessageFactory as _
from quintagroup.formlib.captcha import Captcha
from quintagroup.formlib.captcha import CaptchaWidget
from plone.app.users.browser.register import RegistrationForm
from zope.interface import Interface
from zope.formlib import form

class ICaptchaSchema(Interface):
    captcha = Captcha(
        title=_(u'Prevent spam'),
        description=_(
            u'Type the text in the picture.'
        ),
    )

class CustomRegistrationForm(RegistrationForm):
    """ Custom registration form
    """
    @property
    def form_fields(self):
        fields = super(CustomRegistrationForm, self).form_fields
        fields += form.Fields(ICaptchaSchema)
        fields['captcha'].custom_widget = CaptchaWidget
        return fields
