header属性设置为None的GET请求将引发具有urllib3的TypeError

import urllib3

http = urllib3.PoolManager()

headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3',
    'Authorization': 'Bearer your_token'
}

try:
    response = http.request('GET', 'https://example.com', headers=headers)
    print(response.data)
except urllib3.exceptions.HTTPError as e:
    print('HTTPError occurred:', e)
except urllib3.exceptions.URLError as e:
    print('URLError occurred:', e)
except urllib3.exceptions.RequestError as e:
    print('RequestError occurred:', e)
except TypeError as e:
    print('TypeError occurred:', e)
