我用了corsheaders配置CORS设置，为什么`本地主机：8080`访问仍然得到错误？

Question

我在Django后端使用了csrfheaders，但我使用前端访问API，仍然得到以下错误：

Response to preflight request doesn't pass access control check: The value of the 'Access-Control-Allow-Origin' header in the response must not be the wildcard '*' when the request's credentials mode is 'include'. Origin 'http://localhost:8080' is therefore not allowed access. The credentials mode of requests initiated by the XMLHttpRequest is controlled by the withCredentials attribute.

我的Django后端项目的settings.py：

import os

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

SECRET_KEY = '8cyiv%(rkpv33s_(n8x_5&+6-9&s!ddc!0)98la3=9(y8=k$4u'

你看我已经用corsheaders配置了CORS设置，为什么当localhost:8080access仍然得到错误？在

一些用户怀疑是因为ALLOWED_HOSTS=['*']，我不这么认为，我还测试了，将允许的主机更改为：

^{pr2}$

都不管用，还是这个问题。在
