Django-通过AJAX发送数据后，不允许使用方法（POST）

Question

错误：通过POST方法通过AJAX提交表单时发生Method Not Allowed (POST): / 405。最终，这应采用所有提交的值（first_name，last_name，电话，电子邮件），并将它们分别保存到带有外键的适当模型中。我目前正在使用基于类的视图，并且在def post中，我必须通过简单的验证来保存对象，但是几个小时我不知道该怎么做。

urlpatterns = [
    path('', views.AddressView.as_view()),

    path('delete/<int:pk>/', views.AddressDelete.as_view()),
]
