设置会话变量的CORS策略块

Question

我是Django的新手，目前正在使用ReactTSX和Django开发一个应用程序。我使用Django作为后端，每当尝试为请求会话变量赋值时，都会出现列出的错误。

Login Page

import Cookies from "js-cookie";

axios.request({
    url: "login/",
    baseURL: window.BACKEND_BASEURL,
    method: "POST",
    data: data,
    timeout: 15000,
    withCredentials: true,
    headers: { "X-Requested-With": "XMLHttpRequest", "X-CSRFToken": Cookies.get("csrftoken") },
    validateStatus: () => true
}).then((res: AxiosResponse): void => {

http://localhost:8000/login/

def get(r):
    r.session["user_id"] = "ME"       <-- Causing ERROR when assigning a variable

settings.py

CORS_ORIGIN_ALLOW_ALL = True
CORS_ALLOW_CREDENTIALS = True
CORS_ALLOW_METHODS = ["GET","POST"]
CORS_ALLOW_HEADERS = [ "accept", "accept-encoding", "authorization", "content-type", "dnt", "origin", "user-agent", "x-csrftoken", "x-requested-with" ]

Error
