django Error: That IP address can‘t be assigned to.

運行環境：

系統:阿里雲Ubuntu 18.04.3 LTS (GNU/Linux 4.15.0-52-generic x86_64)

python:python3

mysql:5.7.27-0ubuntu0.18.04.1 (Ubuntu)

mysql-client:5.7.27-0ubuntu0.18.04.1 (Ubuntu)

報錯描述：

    在啓動Django程序(python manage.py runserver)時報錯"That IP address can't be assigned to."

解決辦法:

    在settings.py中設置ALLOWED_HOSTS,如

ALLOWED_HOSTS = ['47.244.35.68','localhost', '47.244.35.68:10001', '127.0.0.1','jokeropen.com']

然後在啓動的時候將python manage.py runserver改爲python manage.py runserver 0:10001(10001是已開放的端口)。問題解決
