爬蟲遇到證書報錯-忽略它 ssl.CertificateError

如果在爬取過程中出現 ssl.CertificateError 報錯信息 , 這樣是證書認證報錯, 這樣可以去忽略它

 

from urllib.request import Request,urlopen
from fake_useragent import UserAgent
import ssl

url = "https://www.12306.cn/mormhweb/"
headers ={
    "User-Agent":UserAgent().chrome
}
request = Request(url,headers=headers)

###忽略驗證證書
context = ssl._create_unverified_context()    ###把這個加進去就可以忽略證書認證
response = urlopen(request,context=context)
info=response.read().decode()
