Invalid HTTP_HOST header: 'xxx.xx.xxx.xxx:8000'. You may need to add 'xxx.xx' to ALLOWED_HOSTS

用python3 manage.py runserver 0.0.0.0:8000命令运行django程序后，通过浏览器访问服务器网址的8000端口，出现访问错误，报错为
Invalid HTTP_HOST header: ‘xxx.xx.xxx.xxx:8000’. You may need to add ‘xxx.xx’ to ALLOWED_HOSTS

解决办法：
修改创建项目时生成的setting.py文件

将ALLOWED_HOSTS = []改为ALLOWED_HOSTS = ['*']

再次运行即可成功访问。
