Python Flask 记录到多个文件

如何解决Python Flask 记录到多个文件

我有一个 Flask 应用程序，它从 2 个不同的文件调用 2 个函数。我已经设置日志记录到 2 个不同的文件。但是，日志记录似乎总是附加到一个文件中（无论先到达哪个端点）

这里是文件的结构 -

app.py

document.getElementById('add').addEventListener('click',function(e){
e.preventDefault();
// getting the list
var list=document.getElementById('playlist');
// getting the value from form
var text=document.getElementById('title').value;
// creating the new list item
var newTag =document.createElement('li');
// setting the class to list item
newTag.setAttribute('class','list-group-item');
// appending the list item value that is got from the form
newTag.appendChild(document.createTextNode(text));
// adding the list item to the list
list.appendChild(newTag)
// console.log(newTag)
});
var list=document.getElementById('playlist');
list.addEventListener('click',remove);
function remove(e){
    if(e.target.classList.contains('delete')){
        var li=e.target.parentElement;
        list.removeChild(li)
    }
}
let addbtn=document.getElementById('addtoplayer');
addbtn.addEventListener('click',addtoplayer)
function addtoplayer(){
    let getUi=document.getElementById('playlist');
    getUi=document.getChildNodes;
    console.log(getUi)
}

file1.py

        <meta charset="UTF-8">
        <meta http-equiv="X-UA-Compatible" content="IE=edge">

            <input type="text" id="title" class="form-control m-2">
            <input type="submit" value="Add" class="btn btn-primary m-2" id="add">
        </form>
        <div class="container">
            <div class="card shadow">
                <div class="card-header text-center bg-light">

                <div class="card-body p-0">
                    <ul id="playlist" class="list-group">
                        <li class="list-group-item" data-name="song title" data-artits="artist name" data-path="path-to-song.mp3" data-pic="cover.jpg">song 1<span class="badge badge-danger float-right delete" data-id="1" id="remove">X</span></li>
                        <li class="list-group-item" data-name="song title" data-artits="artist name" data-path="path-to-song.mp3" data-pic="cover.jpg">song 2<span class="badge badge-danger float-right delete" data-id="2" id="remove">X</span></li>
                        <li class="list-group-item" data-name="song title" data-artits="artist name" data-path="path-to-song.mp3" data-pic="cover.jpg">song 3<span class="badge badge-danger float-right delete" data-id="3" id="remove">X</span></li>
                        <li class="list-group-item" data-name="song title" data-artits="artist name" data-path="path-to-song.mp3" data-pic="cover.jpg">song 4<span class="badge badge-danger float-right delete" data-id="4" id="remove">X</span></li>
                        
                    </ul>
                </div>
            </div>
           <button id="addtoplayer" class="btn btn-dark btn-block my-4">Add to player</button>
            <div id="player"></div>
        </div>
        <script src="main.js"></script>
    </body>
    </html>

file2.py

from file1 import fun1
from file2 import fun2
 
@app.route("/end_point1")
def data_1:
    return fun1()
     
@app.route("/end_point2")
def data_2:
    return fun2()

当我运行单个 python 文件 - file1.py / file2.py 时，这个记录很好（单独）但是当我运行 API 时，日志只会附加到一个文件中。

我的日志记录有什么问题？我该如何解决？

解决方法

将此添加到 logger_setup.py

import logging
from pathlib import Path
formatter = logging.Formatter('%(asctime)s - %(levelname)s - [%(filename)s:%(lineno)d] - %(message)s')


def setup_logger( name,log_file,level=logging.DEBUG): 

    my_file = Path(log_file)
    # print("check the if condition for the file")
    # print(my_file.is_file())

    if my_file.is_file():
        #print(logging.getLogger(name).hasHandlers())
        # if logging.getLogger(name).hasHandlers():
        if len(logging.getLogger(name).handlers)>0:
            return logging.getLogger(name)
        else:
            handler = logging.FileHandler(log_file,mode='a')        
            handler.setFormatter(formatter)
            logger = logging.getLogger(name)
            logger.setLevel(level)
            logger.addHandler(handler)
            logger.propagate = False
            return logger
    else:
        handler = logging.FileHandler(log_file,mode='a')        
        handler.setFormatter(formatter)

        logger = logging.getLogger(name)
        logger.setLevel(level)
        logger.addHandler(handler)
        logger.propagate = False
        return logger

在文件 1 和 2 中，您可以使用类似这样的内容

import logging
import logger_setup

def fun1():
    log_location = 'logs'
    logger = logger_setup.setup_logger(__name__,log_location+__name__+'.log')
    logger.info("Logging function 1 details to to file1")
    return "1"
