Estou tentando usar Python para fazer login em um site e reunir informações de várias páginas da web e recebo o seguinte erro:
Traceback (most recent call last): File "extract_test.py", line 43, in <module> 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
Usei time.sleep()
e funciona, mas parece pouco inteligente e confiável, existe alguma outra maneira de evitar esse erro?
Este é meu código:
import mechanize
import cookielib
import re
first=("example.com/page1")
second=("example.com/page2")
third=("example.com/page3")
fourth=("example.com/page4")
## I have seven URL's I want to open
urls_list=[first,second,third,fourth]
br = mechanize.Browser()
# Cookie Jar
cj = cookielib.LWPCookieJar()
br.set_cookiejar(cj)
# Browser options
br.set_handle_equiv(True)
br.set_handle_redirect(True)
br.set_handle_referer(True)
br.set_handle_robots(False)
# Log in credentials
br.open("example.com")
br.select_form(nr=0)
br["username"] = "username"
br["password"] = "password"
br.submit()
for url in urls_list:
br.open(url)
print re.findall("Some String")
sleep
.
