为什么pythonanywhere会出现DisallowedHost

Question

为什么 pythonanywhere 显示 DisallowedHost at :

无效的 HTTP_HOST 标头：“kimmy.pythonanywhere.com”。您可能需要 将“kimmy.pythonanywhere.com”添加到 ALLOWED_HOSTS。

我已经在

ALLOWED_HOSTS = ['kimmy.pythonanywhere.com']

中设置了

setting.py

但没有任何改变。

我想我有完全相同的问题：我试图在 PythonAnywhere 上部署我的 Django 博客应用程序，但我收到错误，未从 .env 文件中读取 ALLOWED_HOSTS 和 SECRET_KEY （我在设置的同一文件夹中创建了它） .py，在主项目文件夹中）。

这是我的设置.py：

from dotenv import load_dotenv
from pathlib import Path
import logging
import os
import sys
    
load_dotenv()
# Build paths inside the project like this: BASE_DIR / 'subdir'.
BASE_DIR = Path(__file__).resolve().parent.parent
    
    
# Quick-start development settings - unsuitable for production
# See https://docs.djangoproject.com/en/5.1/howto/deployment/checklist/
    
SECRET_KEY = os.getenv("SECRET_KEY")
    
Logger = logging.getLogger(__name__)
Logger.error(Path.cwd())
    
IS_PRODUCTION = os.getenv('DJANGO_PRODUCTION', 'False') == 'True'
    
if IS_PRODUCTION:
    DEBUG = False
    ALLOWED_HOSTS = ['sirjude.pythonanywhere.com']
    
    # # Security settings for production
    # SECURE_HSTS_SECONDS = 31536000  # 1 year
    # SECURE_HSTS_INCLUDE_SUBDOMAINS = True
    # SECURE_HSTS_PRELOAD = True
    SECURE_SSL_REDIRECT = True
    SESSION_COOKIE_SECURE = True
    CSRF_COOKIE_SECURE = True
else:
    DEBUG = True
    ALLOWED_HOSTS = ['localhost', '127.0.0.1']
...

这是我的 .env 文件，位于 settings.py 所在的同一文件夹中：

SECRET_KEY=<my django secret key>
DJANGO_PRODUCTION=False
DB_ENGINE=django.db.backends.postgresql
DB_NAME=app
DB_USER=super
DB_PASSWORD=<my postgrespassword>
DB_HOST=SirJude-4090.postgres.pythonanywhere-services.com
DB_PORT=14090

...但我不断收到此错误：

2024-10-08 12:46:38,548: Invalid HTTP_HOST header: 'sirjude.pythonanywhere.com'. You may need to add 'sirjude.pythonanywhere.com' to ALLOWED_HOSTS.
