Python Mechanize browser.forms()

Question

我尝试列出页面 https://www.fmgroup.pl/login 上的所有表单使用 Python mechanize 模块和 browser.forms() 函数。

URL = 'https://www.fmgroup.pl/login'
br = mechanize.Browser()

br.open(URL)
for form in br.forms():
   print str(form)

我收到此错误:

Traceback (most recent call last):
  File "brows.py", line 25, in <module>
    for form in br.forms():
  File "build\bdist.win32\egg\mechanize\_mechanize.py", line 420, in forms

mechanize._form.ParseError: OPTION outside of SELECT

我尝试使用不同的模块，但它们没有给我任何形式的结果。

Answer 1

我解决了这个问题:

import requests
import sys
import urllib2
import re
import mechanize
import cookielib
from bs4 import BeautifulSoup


URL = 'https://www.fmgroup.pl/login'
address = 'https://www.fmgroup.pl/panel/developedtree'
br = mechanize.Browser()

response = br.open(URL)
soup = BeautifulSoup(response.read())
for div in soup.findAll('select'):
    div.extract()


response.set_data(str(soup))
br.set_response(response)

br.select_form(nr=0)

但我还有另一个问题:

br.form['YumUserLogin[username]'] = LOGIN
br.form['YumUserLogin_password'] = PASSWORD

错误:

Traceback (most recent call last):
  File "brows.py", line 37, in <module>
    br.form['YumUserLogin[username]'] = LOGIN
  File "build\bdist.win32\egg\mechanize\_form.py", line 2780, in __setitem__
  File "build\bdist.win32\egg\mechanize\_form.py", line 3101, in find_control
  File "build\bdist.win32\egg\mechanize\_form.py", line 3185, in _find_control
mechanize._form.ControlNotFoundError: no control matching name 'YumUserLogin[username]'

看起来像:

<GET https://www.fmgroup.pl/search/search application/x-www-form-urlencoded
  <TextControl(q=)>
  <SubmitControl(yt0= ) (readonly)>>
<POST https://www.fmgroup.pl/user/auth/login application/x-www-form-urlencoded
  <HiddenControl(returnUrl=/panel) (readonly)>
  <HiddenControl(tag=ajax) (readonly)>
  <TextControl(YumUserLogin[username]=)>
  <PasswordControl(YumUserLogin[password]=)>
  <HiddenControl(YumUserLogin[rememberMe]=0) (readonly)>
  <CheckboxControl(YumUserLogin[rememberMe]=[1])>
  <SubmitControl(<None>=Zaloguj) (readonly)>>
