Question

我将uWSGI设置更改为使用Emperor进行多应用程序部署。在加载mypasswords.pwds＆＃39;时使用旧设置在我的应用旁边保存的文件，没有问题。

现在我和皇帝一起运行所有的东西＆＃39;没有这样的文件或目标＆＃39;错误。这可能是因为我的设置或因为皇帝只是以不同的方式工作而且我不确定是什么情况。

目录树：

Project
    thisismyapp.py
    passwords.pwds

配置uWSGI Emperor：

[uwsgi]
# Variables
base = /var/www/Project

# Generic Config
home = %(base)/venv
pythonpath = %(base)
socket = /tmp/%n.sock
module = thisismyapp:app # Is this an issue?
logto = /var/log/uwsgi/%n.log

[Errno 2] No such file or directory: 'passwords.pwds'

Python文件访问：

f = open('passwords.pwds', 'r')

Answer 1

试试这个：

from os import path

passwords_location = path.join(path.dirname(path.realpath(__file__), 'passwords.pwds'))
with open(passwords_location) as f:
    do_something()

使用相对位置的原始方式，如果您不在“项目”文件夹中，可能无法找到该文件。另外，使用with块是处理文件的更好方法，它将确保在退出上下文块时关闭文件。

将目录中的文件提供给uWSGI Flask应用程序与Emperor一起运行
