如何使用Flask + WSGI在我的项目中使用文件夹?

标签: python flask wsgi

我可以使用Flask + WSGI成功运行一个“ hello world”应用程序...但是在“文件夹”中使用“ routes.py”更改我的项目结构会使服务器出现错误...

  

mod_wsgi(pid = 9):目标WSGI脚本'/var/www/myfirstapp/hello.wsgi'无法作为Python模块加载。

     

mod_wsgi(pid = 9):处理WSGI脚本'/var/www/myfirstapp/hello.wsgi'时发生异常

     

从folder.routes导入simple_page

     

ImportError:没有名为folder.routes的模块

这是我的项目树:

├── folder
│   └── routes.py
├── hello.conf
├── hello.py
├── hello.wsgi
└── README.md

hello.py:

from flask import Flask
from folder.routes import simple_page # works in dev but not with wsgi.. Why?


app = Flask(__name__)
app.register_blueprint(simple_page)

route.py:

from flask import Blueprint, render_template, abort
from jinja2 import TemplateNotFound

simple_page = Blueprint('simple_page', __name__,
                        template_folder='templates')

@simple_page.route('/')
def index():
    try:
        return "Hello world"
    except TemplateNotFound:
        abort(404)

hello.conf

<VirtualHost *>
    ServerName example.com
    WSGIScriptAlias / /var/www/myfirstapp/hello.wsgi
    WSGIDaemonProcess hello python-path=/var/www/myfirstapp:/var/www/myfirstapp/.env/lib/python3.5/site-packages
    <Directory /var/www/myfirstapp>
       WSGIProcessGroup hello
       WSGIApplicationGroup %{GLOBAL}
        Order deny,allow
        Allow from all
    </Directory>
</VirtualHost>

hello.wsgi:

import sys
sys.path.insert(0, "/var/www/myfirstapp")
from hello import app as application

注意:我不明白为什么WSGI在根文件夹中的“ routes.py”(导入路由)是“好”的,但是却抱怨(hello.py)在hello中导入“ folder.routes”。 py,如果我将相同的文件放在“文件夹” ...

1 个答案:

答案 0 :(得分:0)

我找到了一个解决方案,引用了WSGIDaemonProcess hello.conf行中的相应模块(文件夹):

pythonpath=/var/www/myfirstapp/.env/lib/python3.5/sitepackages:/var/www/myfirstapp/:/var/www/myfirstapp/folder

在routes.py中: 而不是from folder.routes import simple_page,我们有了import routes

项目树也发生了一些变化:

├── myfirstapp
│   ├── folder
│   │   └── routes.py
│   └── __init__.py
├── hello.wsgi
└── README.md
