Question

我将Django 2.2.4用于登录功能

from django.contrib.auth import authenticate, login

def login_ajax(request):
    response = {'complete': False}

    if request.method == 'POST':
        data = json.loads(request.body)
        email, password = data['email'], data['password']

        user = authenticate(request, username=email, password=password)

        if user is None:
            #try with email
            user = authenticate(request, email=email, password=password)

        #both checks done so invalid
        if user is None:
            response['error'] = 'Username/Email and Password Combination Failed.'
        else:
            print(user.id)
            login(request, user)
            response['complete'] = True
    else:
        response['error'] = 'no post data found'

    return HttpResponse(
            json.dumps(response),
            content_type="application/json"
        )

可以使用基于Django's documentation的用户名/电子邮件登录，但会引发此错误

join() argument must be str or bytes, not 'User'

据我所知，最好的方法似乎是通过身份验证，然后尝试使用模板，这可能是引发错误的原因。

使用函数错误的Django登录：join（）参数必须为str或字节，而不是'User'
