我正在尝试获取在本地计算机上的终端模拟器上看到的默认日志，该日志运行良好。但是，在 centos 服务器上，当我重新启动 Gunicorn 服务时，我无法将输出输出到日志文件。我想要的日志如下所示：我的解决方法是在虚拟环境中获取 shell 上的日志：

这是我在服务器中的配置：
import os
import logging
import logging.handlers
from flask import Flask, redirect, url_for, render_template, request, session, flash
from datetime import timedelta
from logging.config import dictConfig
dictConfig({
'version': 1,
'handlers': {
'file.handler': {
'class': 'logging.handlers.RotatingFileHandler',
'filename': 'server_werkzeug.log',
'maxBytes': 10000000,
'backupCount': 5,
'level': 'DEBUG',
},
},
'loggers': {
'werkzeug': {
'level': 'INFO',
'handlers': ['file.handler'],
},
},
})
#logging.basicConfig(filename='flask_record.log', level=logging.INFO, format=f'%(asctime)s %(levelname)s %(name)s %(threadName)s : %(message)s')
app = Flask(__name__)```
如果仍然相关：
werkzeug（Flask 使用的 WSGI Web 应用程序库）有一个在开发期间运行的开发服务器。该服务器生成访问日志。使用（例如 Gunicorn）部署到生产时，不使用此开发服务器，并且不会生成任何日志。
我认为你必须自己实现请求日志记录。也许这些链接会有所帮助：
