无法从python的请求库禁用日志记录

Question

我正在尝试从请求库中删除日志记录，我已经阅读并尝试了有关堆栈溢出的其他答案，但它们似乎不起作用

我正在解析网页的html代码中的URL，然后从每个URL下载zip文件。下载所有zip文件后，我从请求库收到一条消息：

从以下网址下载数据：

http://viewfinderpanoramas.org/Coverage%20map%20viewfinderpanoramas_org3.htm

这是我的密码。我正在导入该类并从另一个文件运行download_data方法

import os
import argparse
import requests
import re
import logging
from tqdm import tqdm

"""
Downloads all zip files from the viewfinder panoramas elevation dataset
"""

class ElevationScraper:
    def __init__(self):
        self.data_url = "http://viewfinderpanoramas.org/Coverage%20map%20viewfinderpanoramas_org3.htm"
        self.base_dir = "./data/elevation/"
        self.elevation_dir = os.path.join(self.base_dir, "elevation")
        logging.getLogger("requests").setLevel(logging.WARNING)
        logging.getLogger("requests").propagate = True

        
    def download_data(self):
        # get html from self.data_url and get all urls in the html code
        req = requests.get(self.data_url)
        urls = re.findall(r"\"(https?://\S+)\"", str(req.text))

        # first four are irrelevant links so remove those
        urls = urls[4:]
        with open(os.path.join(self.base_dir, "urls.txt"), "w") as url_file:
            for url in urls:
                url_file.write(url + "\n")
        
        # downloading all zip files
        if not os.path.exists(self.elevation_dir):
            os.mkdir(self.elevation_dir)

        print("Downloading " + str(len(urls)) + " data files to " + self.elevation_dir + " from " + self.data_url)
        
        for url in tqdm(urls[:3]):
            filename = url.split("/")[-1]

            with open(os.path.join(self.base_dir, "elevation", filename), "wb") as data_file:
                req = requests.get(url)
                data_file.write(req.content)

输出：

您可以像这样将setLevel更改为临界值logging.getLogger("requests").setLevel(logging.CRITICAL)，也可以使用requests.packages.urllib3.disable_warnings()。请参见：How do I disable log messages from the Requests library?。像这样的问题总是被问到
