我正在尝试学习如何自动从页面获取URL。在下面的代码中,我试图获取网页的标题:
import urllib.request
import re
url = "http://www.google.com"
regex = r'<title>(,+?)</title>'
pattern = re.compile(regex)
with urllib.request.urlopen(url) as response:
html = response.read()
title = re.findall(pattern, html)
print(title)
我得到这个意外的错误:
Traceback (most recent call last):
File "path\to\file\Crawler.py", line 11, in <module>
title = re.findall(pattern, html)
File "C:\Python33\lib\re.py", line 201, in findall
return _compile(pattern, flags).findall(string)
TypeError: can't use a string pattern on a bytes-like object
我究竟做错了什么?
