一、关于配置
django: 配置为AUTHENTICATION_BACKENDS
restful: 配置为 DEFAULT_AUTHENTICATION_CLASSES
REST_FRAMEWORK = { 'DEFAULT_AUTHENTICATION_CLASSES': [ 'rest_framework.authentication.BasicAuthentication', 'rest_framework.authentication.SessionAuthentication', 'rest_framework.authentication.TokenAuthentication', 'rest_framework_simplejwt.authentication.JWTAuthentication', ], 'DEFAULT_PAGINATION_CLASS': 'rest_framework.pagination.PageNumberPagination', 'PAGE_SIZE': 2 } AUTHENTICATION_BACKENDS = ( #new 'rest_framework.authentication.TokenAuthentication', #default ModelBackend 'django.contrib.auth.backends.ModelBackend', )
二、django什么时候调用authenticate?
1.django, 在login view中,进行用户验证时, 调用 django.contrib.auth.authenticate.
def login_custom(request): if request.method == 'POST': # create a form instance and populate it with data from the request: form = myAuthenticationForm(request.POST) # check whether it's valid: if form.is_valid(): username = form.cleaned_data['username'] password = form.cleaned_data['password'] user = authenticate(request, username=username, password=password) if user is not None: login(request, user) return redirect('login:home') else: return render(request, 'registration_my/login_custom.html', {'form': form})
验证的参数: 可以是username+password, 也可以是token,
返回:none 或 setting. AUTH_USER_MODEL (如果不custom,则是auth.user)
注意,如果不调用 django.contrib.auth.authenticate. 那么setting. AUTHENTICATION_BACKENDS根本用不上,就不会被调用。
3. restful 什么时候调用DEFAULT_AUTHENTICATION_CLASSES 中的定义类?
2.restful , 在login view中,进行用户验证时, 调用 django.contrib.auth.authenticate.
4. 2个配置参数的共同点
DEFAULT_AUTHENTICATION_CLASSES、AUTHENTICATION_BACKENDS 可以定制多个类, 有框架默认,还可以自己定制。
返回参数不同, 调用机制一样。none,user,token.
