我认为已经完成了。

添加到settings.py

  SOCIALACCOUNT_ADAPTER = 'adapter.SocialAccountAdapter'

创建

#project/settings/adapter.py
from django.contrib.auth.models import User
from django.shortcuts import HttpResponse,redirect
from allauth.account.models import EmailAddress
from allauth.exceptions import ImmediateHttpResponse
from allauth.socialaccount.signals import pre_social_login
from allauth.account.utils import perform_login
from django.dispatch import receiver
from allauth.socialaccount.adapter import DefaultSocialAccountAdapter  

class SocialAccountAdapter(DefaultSocialAccountAdapter):
    def pre_social_login(self, request, sociallogin):
            pass

@receiver(pre_social_login)
def link_to_local_user(sender, request, sociallogin, **kwargs):
        try:
            user = User.objects.get(email=sociallogin.account.user.email)
            if user:
                perform_login(request, user, email_verification='optional')
                raise ImmediateHttpResponse(redirect('/your/url/'))
        except User.DoesNotExist:
            user = User.objects.get(id=request.user.id)
            sociallogin.connect(request, user)`

django-allauth社交账户已经退出
