python如何使用flask中的werkzeug记录器将错误消息写入错误日志和主日志

from flask import Flask
from werkzeug.exceptions import HTTPException
from werkzeug.exceptions import default_exceptions
import logging
from logging.handlers import RotatingFileHandler

app = Flask(__name__)

# 创建主日志记录器
handler = RotatingFileHandler('app.log', maxBytes=10000, backupCount=1)
handler.setLevel(logging.INFO)
app.logger.addHandler(handler)

# 创建错误日志记录器
error_handler = RotatingFileHandler('error.log', maxBytes=10000, backupCount=1)
error_handler.setLevel(logging.ERROR)
app.logger.addHandler(error_handler)

# 禁用Flask默认的日志处理器
app.logger.removeHandler(app.logger.handlers[0])

def handle_error(error):
    code = 500
    if isinstance(error, HTTPException):
        code = error.code
    app.logger.error(error)
    return "Error occurred", code

# 注册错误处理函数
for code in default_exceptions.keys():
    app.errorhandler(code)(handle_error)

@app.route('/')
def index():
    app.logger.info('Processing index request')
    return 'Hello, World!'

@app.route('/error')
def error():
    raise Exception('An error occurred')
