python爬虫—URLError的使用

python爬虫—URLError的使用,能够看到结果是404,还是超时

from urllib.request import Request,urlopen
from fake_useragent import UserAgent
from urllib.error import  URLError

url ="https://www.baidu123.comasda/"

headers = {
    "User-Agent":UserAgent().chrome

}
try:
    request = Request(url,headers= headers)

    response = urlopen(request)

    print(response.read().decode())

except URLError as e :
    if e.args == ():
        print(e.code)#404和超时
    else:
        print(e.args[0].errno)
    print(e)
