我尝试使用Python登录网站并从多个网页收集信息,但出现以下错误:
Traceback (most recent call last):
File"extract_test.py", line 43, in
response=br.open(v)
File"/usr/local/lib/python2.7/dist-packages/mechanize/_mechanize.py", line 203, in open
return self._mech_open(url, data, timeout=timeout)
File"/usr/local/lib/python2.7/dist-packages/mechanize/_mechanize.py", line 255, in _mech_open
raise response
mechanize._response.httperror_seek_wrapper: HTTP Error 429: Unknown Response Code
我使用了time.sleep(),它可以工作,但看起来不智能且不可靠,还有其他方法可以避免此错误吗?
这是我的代码:
import mechanize
import cookielib
import re
first=("example.com/page1")
second=("example.com/page2")
third=("example.com/page3")
fourth=("example.com/page4")
