问题：

PC: 10.245.36.203上通过chrome访问，http://10.245.242.221:8000时报错，并且此时在Linux上同时有错误log显示：

Invalid HTTP_HOST header: '10.245.242.221:8000'. You may need to add u'10.245.242.221' to ALLOWED_HOSTS.

 

解决方案：

添加10.245.242.221到allowed_hosts.

 

修改setting.py

......

# SECURITY WARNING: don't run with debug turned on in production!

DEBUG = True

ALLOWED_HOSTS = ['10.245.242.221']
