Azure Django 应用程序有 SECRET_KEY 异常

编程问答 2022-05-27

问题描述

我使用 GitHub 在 azure 上部署了我的 django 网络应用程序，但我得到的错误是：

django.core.exceptions.ImproperlyConfigured：SECRET_KEY 设置不能为空。

我的 settings.py 文件是

import os

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

SECRET_KEY = os.getenv('SECRET_KEY')

DEBUG = False

TEMPLATE_DEBUG = DEBUG

ALLOWED_HOSTS = os.getenv('ALLOWED_HOSTS')


STATICFILES_Dirs = [
    os.path.join(BASE_DIR,'static/'),"C:/Users/ande/Documents/FC_Database/FC_Database/frontend/templates/frontend/index.html"
]

            'context_processors': [
                'django.template.context_processors.debug','django.template.context_processors.request','django.contrib.auth.context_processors.auth','django.contrib.messages.context_processors.messages',],},]

    }
}

USE_I18N = True

USE_L10N = True

USE_TZ = True


# Static files (CSS,JavaScript,Images)

STATIC_URL = '/static/'

MEDIA_ROOT = os.path.join(BASE_DIR,'media')
MEDIA_URL = '/media/'

出于安全原因，我在 Azure 的应用程序设置中添加了密钥和其他数据库设置，但仍然无法正常工作。

有谁知道如何解决这个问题？

解决方法

Python 允许您使用 os.environ 字典检索环境变量的内容，其中键是您试图获取内容的变量的名称。

这是可用于从 Azure WebApp 检索环境变量的部分代码

import os
...
SECRET_KEY = os.environ['SECRET_KEY']
...
