【问题描述】：
我发现a gist 可以让我将 CherryPy 网络服务器集成到我的程序中，并通过该 CherryPy 网络服务器运行 Django 项目。但是，我在让事情正常工作时遇到了一些困难。
这是我的代码中的类，基本没有变化
class ClientThread(object):
HOST = "127.0.0.1"
PORT = int("3852")
DIR = "/home/user/project/"
STATIC_ROOT = DIR + '/clientFiles/static/'
def mount_static(self, url, root):
"""
:param url: Relative url
:param root: Path to static files root
"""
config = {
'tools.staticdir.on': True,
'tools.staticdir.dir': root,
'tools.expires.on': True,
'tools.expires.secs': 86400
}
cherrypy.tree.mount(None, url, {'/': config})
def run(self):
cherrypy.config.update({
'server.socket_host': self.HOST,
'server.socket_port': self.PORT,
'engine.autoreload_on': False,
'log.screen': True
})
self.mount_static(settings.STATIC_URL, self.STATIC_ROOT)
cherrypy.tree.graft(WSGIHandler())
cherrypy.engine.start()
print("[Info]: Client started. Use http://{0}:{1} to access the WebApp.".format(self.HOST,self.PORT))
cherrypy.engine.block()
def init(self):
print("[Info]: Starting Client WebApp...")
cThread = Thread(target=self.run)
cThread.start()
整个课程都是通过ClientThread().init()发起的
我的应用顶部要点的前几行（按顺序）：
import os
from threading import Timer
os.environ["DJANGO_SETTINGS_MODULE"] = "clientFiles.settings"
import django
django.setup()
import cherrypy
from django.conf import settings
from django.core.handlers.wsgi import WSGIHandler
我的项目是这样布局的：
.
├── clientFiles
│ ├── clientFiles
│ │ ├── asgi.py
│ │ ├── __init__.py
│ │ ├── __pycache__
│ │ │ ├── __init__.cpython-37.pyc
│ │ │ └── settings.cpython-37.pyc
│ │ ├── settings.py
│ │ ├── urls.py
│ │ └── wsgi.py
│ ├── __init__.py
│ ├── manage.py
│ ├── __pycache__
│ │ └── __init__.cpython-37.pyc
│ └── static
├── main.py
我在根目录中使用 django-admin startproject clientFiles 启动了我的 Django 项目。
当我尝试运行我的程序时，我得到：
Traceback (most recent call last):
File "main.py", line 26, in <module>
django.setup()
File "/usr/local/lib/python3.7/dist-packages/django/__init__.py", line 19, in setup

File "/usr/local/lib/python3.7/dist-packages/django/conf/__init__.py", line 83, in __getattr__
self._setup(name)
File "/usr/local/lib/python3.7/dist-packages/django/conf/__init__.py", line 70, in _setup
self._wrapped = Settings(settings_module)
File "/usr/local/lib/python3.7/dist-packages/django/conf/__init__.py", line 177, in __init__
mod = importlib.import_module(self.SETTINGS_MODULE)
File "/usr/lib/python3.7/importlib/__init__.py", line 127, in import_module
return _bootstrap._gcd_import(name[level:], package, level)
File "<frozen importlib._bootstrap>", line 1006, in _gcd_import
File "<frozen importlib._bootstrap>", line 983, in _find_and_load
File "<frozen importlib._bootstrap>", line 965, in _find_and_load_unlocked
ModuleNotFoundError: No module named 'clientFiles.settings'
看起来是模块加载问题，对吧？
所以我尝试将os.environ["DJANGO_SETTINGS_MODULE"] = "clientFiles.settings" 更改为os.environ["DJANGO_SETTINGS_MODULE"] = "clientFiles.clientFiles.settings"，因为我的 Django 网址在 clientFiles/clientFiles 中
这样做之后，我的应用程序启动表明 CherryPy 启动没有问题：
[24/Dec/2020:04:37:14] ENGINE Bus STARTING
[24/Dec/2020:04:37:14] ENGINE Started monitor thread 'Autoreloader'.

[24/Dec/2020:04:37:14] ENGINE Bus STARTED
[Info]: Client started. Use http://127.0.0.1:3852 to access the WebApp.
但是当我尝试访问http://127.0.0.1:3852 的站点时，我得到：

在控制台中我得到：

好的，所以可能是目录结构的问题......
我将 clientFiles/clientFiles 的内容移动到 clientFiles 中，所以我有这个：
.
├── clientFiles
│ ├── asgi.py
│ ├── __init__.py
│ ├── manage.py
│ ├── __pycache__
│ │ ├── __init__.cpython-37.pyc
│ │ └── settings.cpython-37.pyc
│ ├── settings.py
│ ├── static
│ ├── urls.py
│ └── wsgi.py
├── main.py
啊哈！启动成功。我看到了 Welcome to Django 页面。
但是，当我尝试创建一个用于登录或其他内容的新应用时...
python3 manage.py startapp login
在我现在拥有的 clientFiles 目录中
.
├── asgi.py
├── __init__.py
├── login
│ ├── admin.py
│ ├── apps.py
│ ├── __init__.py
│ ├── migrations
│ │ └── __init__.py
│ ├── models.py
│ ├── tests.py
│ └── views.py
├── manage.py
├── __pycache__
│ ├── __init__.cpython-37.pyc
│ ├── settings.cpython-37.pyc
│ └── urls.cpython-37.pyc
├── settings.py
├── static
├── urls.py
└── wsgi.py
只需按照此处的教程进行操作：https://docs.djangoproject.com/en/3.1/intro/tutorial01/
我已经创建了视图，在登录应用中创建了 urls.py，并将以下内容插入到 clientFiles/urls.py 中：
from django.contrib import admin
from django.urls import include, path
urlpatterns = [
path('login/', include('login.urls')),
path('admin/', admin.site.urls),
]
运行程序...启动正常。但是当我尝试在我的http://127.0.0.1:3852 上浏览任何地方时，我现在得到了
ModuleNotFoundError at /
No module named 'login'
Request Method: GET
Request URL: http://127.0.0.1:3852/

Exception Type: ModuleNotFoundError

Server time: Thu, 24 Dec 2020 04:55:22 +0000
这就是我卡住的地方。我试过修改左右路径，目录结构，为新目录添加额外的 CherryPy 挂载......我不知所措。
如果您有任何想法将不胜感激......或者如果我可以通过不同的方式将网络服务器集成到我的应用程序中，从而能够通过 django 或 Laravel 提供动态和静态内容？
