我如何在DJANGO_SETTINGS_MODULE中定义环境变量？

Question

settings.py

那是我的设置。py该网站未发布，因此未发布该网站，因此此处的秘密密钥无关紧要。

一开始，我试图从Django接收一些Ajax请求

import django
django.setup()

import os

from django.conf import settings

# Build paths inside the project like this: os.path.join(BASE_DIR, ...)
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

# Quick-start development settings - unsuitable for production
# See https://docs.djangoproject.com/en/2.1/howto/deployment/checklist/

# SECURITY WARNING: keep the secret key used in production secret!
SECRET_KEY = "f6-6p&w%mxjh6dnk7n$i9ik$w-5@x*_2-!omr8)qhr)&rqbn&2"

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

ALLOWED_HOSTS = ['127.0.0.1']

    }
}

import sys
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
sys.path.append(BASE_DIR)
os.environ['DJANGO_SETTINGS_MODULE'] = 'mysite.settings'
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings")



LOGGING = {
    'version': 1,

            'level': 'DEBUG',
            'propagate': True,
        },
    },
}

wsgi.py

这是我的wsgi文件的设置。

import os
import mysite.settings

from django.core.wsgi import get_wsgi_application

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'mysite.settings')

application = get_wsgi_application()

manage.py

那是我的文件manage.pyb

#!/usr/bin/env python
import os
import sys
import mysite.settings

print(sys.path)

if __name__ == '__main__':
    os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'mysite.settings')
    try:
        from django.core.management import execute_from_command_line
    except ImportError as exc:
        raise ImportError(
            "Couldn't import Django. Are you sure it's installed and "
            "available on your PYTHONPATH environment variable? Did you "
            "forget to activate a virtual environment?"
        ) from exc
    execute_from_command_line(sys.argv)

我不知道我的错误来自哪里，我之前没有加载过注册表错误，而私钥错误只是为了在上下文中定位我的代码。

感谢您的帮助！
