您可能知道,uwsgidecorators
仅在您的应用在uwsgi
的上下文中运行时才有效,这在文档https://uwsgi-docs.readthedocs.io/en/latest/PythonDecorators.html
我的代码正在使用这些装饰器,例如用于锁定:
@uwsgidecorators.lock
def critical_func():
...
当我使用uwsgi部署我的应用程序时,这工作得很好,但是,当直接从Python shell启动它时,出现了预期的错误:
File ".../venv/lib/python3.6/site-packages/uwsgidecorators.py", line 10, in <module>
import uwsgi
ModuleNotFoundError: No module named 'uwsgi'
是否有已知的解决方案在两种模式下运行我的应用?显然,在使用简单的解释器时,我不需要同步和其他功能,但是进行一些try-except导入似乎真的很糟糕。
答案 0 :(得分:0)
在此期间,我做了以下实现,很高兴知道有一些更简单的东西:
class _dummy_lock():
"""Implement the uwsgi lock decorator without actually doing any locking"""
def __init__(self, f):
self.f = f
def __call__(self, *args, **kwargs):
return self.f(*args, **kwargs)
class uwsgi_lock():
"""
This is a lock decorator that wraps the uwsgi decorator to allow it to work outside of a uwsgi environment as well.
ONLY STATIC METHODS can be locked using this functionality
"""
def __init__(self, f):
try:
import uwsgidecorators
self.lock = uwsgidecorators.lock(f) # the real uwsgi lock class
except ModuleNotFoundError:
self.lock = _dummy_lock(f)
def __call__(self, *args, **kwargs):
return self.lock(*args, **kwargs)
@staticmethod
@uwsgi_lock
def critical_func():
...
