Django 无密码自定义认证 request.user.is_authenticated' 总是返回false

问题描述

我使用微信openid登录django没有密码，但是自定义验证后端总是返回false，无法被“@login_required”正确识别访问视图。我是新手。非常感谢！

settings.py

AUTHENTICATION_BACKENDS = [
    'django.contrib.auth.backends.ModelBackend','wechat.wechatAuth.WechatAuthBackend',]

自定义认证文件：wechatAuth.py

from accounts.models import CustomUser

class WechatAuthBackend(object):
    def authenticate(self,openid=None):
        try:
            return CustomUser.objects.get(openid=openid)
        except CustomUser.DoesNotExist:
            return None

    def get_user(self,user_id):
        try:
            return CustomUser.objects.get(pk=user_id)
        except CustomUser.DoesNotExist:
            return None

views.py

from django.contrib.auth import authenticate,login

def weixinbind(request):
    if request.user.is_authenticated:   # Always returnfalse
        return HttpResponse('yes login')
    else:
        print(request.user.is_authenticated)
        return HttpResponse('no login')

def weixinbind_callback(request):
    # test data
    data = {"openid": "333"}

    try:
        auth = authenticate(data['openid'])
        login(request,auth,backend='wechat.wechatAuth.WechatAuthBackend')
        print(request.user.is_authenticated)   # Can return correctly true
        return HttpResponse('auth success')

    except:
        user = CustomUser(username = data['openid'],openid = data['openid'])
        user.save()
        return HttpResponse('create success')

调用login()时，可以正确返回“true”，但是在视图函数外访问“false”
