编写注册接口
1.user/urls.py 中添加路由
1.1 user/urls.py 中添加路由
urlpatterns = [
path('register/', views.RegisterView.as_view()), # 注册视图, /user/register/
]
1.2 user/views.py 中写注册视图函数
class RegisterView(APIView):
"""
用户注册, 权限是: 匿名用户可访问
"""

permission_classes = (AllowAny,)

def post(self, request):
    """
    接收邮箱和密码, 前端校验两遍一致性, 注册成功后返回成功, 然后用户自行登录获取token
    1. 随机用户名
    2. 生成用户
    3. 设置用户密码
    4. 保存用户
    :param request:
    :return: {'code':0,'msg':'注册成功'}
    """
    email = request.data.get('email')
    passwrod = request.data.get('password')
    if all([email, passwrod]):
        pass
    else:
        return Response({'code': 9999, 'msg': '参数不全'})
    rand_name = self.randomUsername()
    user = User(username=rand_name, email=email)
    user.set_password(passwrod)
    user.save()
    return Response({'code': 0, 'msg': '注册成功'})

def randomUsername(self):
    """
    生成随机用户名: 格式: SYL + 年月日时分 + 5位随机数
    :return:
    """

    d = datetime.datetime.now()
    base = 'SYL'
    time_str = '%04d%02d%02d%02d%02d' % (d.year, d.month, d.day, d.hour,d.minute)
    rand_num = str(random.randint(10000, 99999))
    return base + time_str + rand_num

2.重写django认证
2.1 syl/settings.py 中指定自定义后端认证函数位置

自定义验证后端

AUTHENTICATION_BACKENDS = ['user.utils.EmailAuthBackend']

2.2 user/utils.py 中重写认证函数

以前使用username进行用户验证，现在修改成email进行验证

class EmailAuthBackend:
def authenticate(self, request, username=None, password=None):
try:
user = User.objects.get(username=username)
except Exception as e:
user = None
if not user:
try:
user = User.objects.get(email=username)
except Exception as e:
user = None
if user and user.check_password(password):
return user
else:
return None
def get_user(self, user_id):
try:
return User.objects.get(pk=user_id)
except User.DoesNotExist:
return None
