当Debug = True在settings.py中时，我的django应用程序工作正常（没有任何错误），但当我将其切换到Debug = False时，我得到了服务器错误（500）。
加上我得到：

  • 未声明HTML文档得字符编码.如果文档包含US-ASCII范围之外得字符，则在某些浏览器配置中，文档将呈现为乱码文本.必须在文档或传输协议中声明页面得字符编码.
  • 404页面未找到

我的设置.py文件：

当你设置DEBUG=False时，Django不再处理你的静态文件。背后的想法是你需要设置一个合适的生产系统。我想你正在使用Heroku，所以我在这里附上了一个（测试过的）生产设置文件的配置（我建议你创建一个专用的生产设置文件，就像下面的例子）。
settings.py：

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
# and here the rest of your local settings
# ...

WSGI_APPLICATION = 'your-app-name.wsgi.application'

# Database
DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
    }
}

# Password validation
AUTH_PASSWORD_VALIDATORS = []

# Static files configuration
STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles')
STATIC_URL = os.path.join(BASE_DIR, 'static/')
STATICFILES_DIRS = (
    os.path.join(BASE_DIR, 'static'),
)

STATICFILES_FINDERS = (
    'django.contrib.staticfiles.finders.FileSystemFinder',
    'django.contrib.staticfiles.finders.AppDirectoriesFinder',
)

# ...

# Loading test/prod settings based on ENV settings
ENV = os.environ.get('ENV')

if ENV == 'prod':
    try:
        from .production_settings import *
        MIDDLEWARE.append('whitenoise.middleware.WhiteNoiseMiddleware',)
    except ImportError:
        pass

production_settings.py（适用于Heroku）：

import os

DEBUG = False

SECRET_KEY = os.environ.get('SECRET_KEY')

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': os.environ.get('DB_NAME'),
        'USER': os.environ.get('DB_USER'),
        'PASSWORD': os.environ.get('DB_PASSWORD'),
        'HOST': os.environ.get('DB_HOST'),
        'PORT': '5432',
    }
}

# Password validation (I removed them in the local settings)
AUTH_PASSWORD_VALIDATORS = [
    {'NAME': 'django.contrib.auth.password_validation.UserAttributeSimilarityValidator'},
    {'NAME': 'django.contrib.auth.password_validation.MinimumLengthValidator'},
    {'NAME': 'django.contrib.auth.password_validation.CommonPasswordValidator'},
    {'NAME': 'django.contrib.auth.password_validation.NumericPasswordValidator'},
]

ALLOWED_HOSTS = (
    'your-app-name.herokuapp.com',
    'localhost',
)

EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'

SECURE_SSL_REDIRECT = True
SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https')
CSRF_COOKIE_SECURE = True
SESSION_COOKIE_SECURE = True

您的wsgi.py文件已经就绪。请确保您有Procfile、requirements.txt文件，并在Heroku Jmeter 板上的“Config Vars”部分下设置了您的环境变量（dashboard.heroku.com/your-app-name/axdos/settings）。在这里您需要设置SECRET_KEY、DB_NAME、DB_USER、DB_PASSWORD、DB_HOST，最后是ENV（此env需要等于prod）。您可以在dashboard.heroku.com/your-app-name/axdos/resources下找到db凭据。

添加后，将WhiteNoise添加到中间件

MIDDLEWARE = [
  # 'django.middleware.security.SecurityMiddleware',
  'whitenoise.middleware.WhiteNoiseMiddleware',
  # ...
]

执行此命令

python manage.py collectstatic --noinput
