1.URLError

try: ???response = request.urlopen(‘http://gxj.com‘)except error.URLError as e: ???print(e.reason)

2.HTTPError

try: ???response =request.urlopen(‘https://cuiqingcai.com/index.htm‘)except error.HTTPError as ?e: ???print(e.code, e.headers, e.reason)

3.最好的写法先捕获子类的错误在捕获父类

try: ???response = request.urlopen(‘https://cuiqingcai.com/index.htm‘)except error.HTTPError as e: ???print(e.reason, e.code, e.headers)except error.URLError as e: ???print(e.reason)else: ???print(‘Request Successfully‘)#4.error 里reason属性返回的不一定是字符串，也可能是一个对象try: ???response = urllib.request.urlopen(‘https://cuiqingcai.com‘, timeout=1)except socket.timeout as e: ???print(type(e))
