做一个接口查询时，碰到要在header中填写认证身份信息的，要怎么写代码呢？

Maybe following code can help

from urllib import request, error
from urllib.parse import urlsplit
from base64 import b64encode, b64decode
import zlib
import brotli
from http import client


def read_URL(url, data=None, headers=None, encoding='utf-8', errors='ignore',
             user=None, password=None, byte=False):
    """

    Compress method for gzip, deflate, br dealed internally.
    :Parameter
      url     : string or a Request object.
      data    : an object specifying additional data to be sent, or None.
      headers : dictionary, header of Http request entity.
      encoding: name of encoding to convert bytes into string.
      errors  : error process, 'strict', 'ignore', 'replace', ...
      user    : string, user name.
      password: string, password.
      byte    : flag for not decoding by encoding
    :Return

    if not headers:
        url_base = urlsplit(url).netloc

    data = response.read()

    return (response, html)

感谢二楼的回复，测试了，没有返回值
