django如何设置csrf_token

from django.views.decorators.csrf import ensure_csrf_cookie
from django.utils.decorators import method_decorator
from django.views import View
class LoginView(View):
    @method_decorator(ensure_csrf_cookie)
    def get(self, request):
        pass
    def post(self, request):
        pass

// get cookie using jQuery
  function getCookie(name) {
    let cookieValue = null;
    if (document.cookie && document.cookie !== '') {
      let cookies = document.cookie.split(';');
      for (let i = 0; i < cookies.length; i++) {
        let cookie = jQuery.trim(cookies[i]);
        // Does this cookie string begin with the name we want?
        if (cookie.substring(0, name.length + 1) === (name + '=')) {
          cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
          break;
        }
      }
    }
    return cookieValue;
  }
  function csrfSafeMethod(method) {
    // these HTTP methods do not require CSRF protection
    return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method));
  }
  // Setting the token on the AJAX request
  $.ajaxSetup({
    beforeSend: function (xhr, settings) {
      if (!csrfSafeMethod(settings.type) && !this.crossDomain) {
        xhr.setRequestHeader("X-CSRFToken", getCookie('csrftoken'));
      }
    }
  });
