我有以下代碼：from urllib.request import urlopenfrom urllib.error import HTTPError, URLErrorfrom bs4 import BeautifulSoup# target = "https://www.rolcruise.co.uk/cruise-detail/1158731-hawaii-round-trip-honolulu-2020-05-23"target = "https://www.rolcruise.co.uk"try: html = urlopen(target)except HTTPError as e: print("You got a HTTP Error. Something wrong with the path.") print("Here is the error code: " + str(e.code)) print("Here is the error reason: " + e.reason) print("Happy for the program to end here"except URLError as e: print("You got a URL Error. Something wrong with the URL.") print("Here is the error reason: " + str(e.reason)) print("Happy for the program to end here")else: bs_obj = BeautifulSoup(html, features="lxml") print(bs_obj)如果我故意在輸入 url 的某些部分時出錯，urlerror 處理工作正常，即如果我故意輸入“htps”而不是“https”，或“ww”而不是“www”，或“u”而不是“英國”。例如target = "https://www.rolcruise.co.u"但是，如果在輸入主機名（“rolcruise”）或 url 的“co”部分時出現(xiàn)錯誤，則 urlerror 將不起作用，我會收到一條錯誤消息，指出 ssl.CertificateError。例如target = "https://www.rolcruise.c.uk"我不明白為什么 URLError 沒有涵蓋在 url 某處有拼寫錯誤的所有場景？鑒于它正在發(fā)生，處理 ssl.CertificateError 的下一步是什么？謝謝你的幫助！

將 ssl 導(dǎo)入您的命名空間以開始：
import ssl
然后你可以捕獲那種異常：
try:
html = urlopen(target)
except HTTPError as e:
print("You got a HTTP Error. Something wrong with the path.")
print("Here is the error code: " + str(e.code))
print("Here is the error reason: " + e.reason)
print("Happy for the program to end here"
except URLError as e:
print("You got a URL Error. Something wrong with the URL.")
print("Here is the error reason: " + str(e.reason))
print("Happy for the program to end here")
except ssl.CertificateError:
# Do your stuff here...
else:
bs_obj = BeautifulSoup(html, features="lxml")
print(bs_obj)
