Python的機械化：提交按鈕將無法正常工作沒有屬性「點擊」

有本網頁形式：https://www.avanza.se/mina-sidor/kontooversikt.html Python的機械化：提交按鈕將無法正常工作沒有屬性「點擊」

我試圖填寫並使用該提交：

# -*- coding: utf-8 -*- 
import cookielib 
import urllib2 
import mechanize 
from bs4 import BeautifulSoup 
from lxml import html 
import urllib2, base64, lxml 
import numpy as np 
import unicodedata 
import datetime 
import re 
import time 

URL = "https://www.avanza.se/mina-sidor/kontooversikt.html" 

br = mechanize.Browser() 

cookiejar = cookielib.LWPCookieJar() 
br.set_cookiejar(cookiejar) 

# Browser options 
br.set_handle_equiv(True) 
br.set_handle_gzip(True) 
br.set_handle_redirect(True) 
br.set_handle_referer(True) 
br.set_handle_robots(False) 

# Follows refresh 0 but not hangs on refresh > 0 
br.set_handle_refresh(mechanize._http.HTTPRefreshProcessor(), max_time=1) 

br.addheaders = [('User-agent', 'Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.1) Gecko/2008071615 Fedora/3.0.1-1.fc9 Firefox/3.0.1')] 

br.open(URL) 

for f in br.forms(): 
    if f.attrs['class'] == 'loginForm clearFix': 
     br.f = f 
    print f 
     break 

br.f[ "j_username" ] = "user" 
br.f[ "j_password" ] = "pass" 

res = br.submit() 

time.sleep(5) 

br.open('https://www.avanza.se/handla/aktier.html/kop/5447/abb-ltd') 

#Getting the response in beautifulsoup 
soup = BeautifulSoup(br.response().read(), 'lxml') 
print(soup.prettify().encode("utf-8"))

和我打印驗證我得到正確的形式：

<div class="section accordion-togglebar"> 
    <a class="toggleBar whiteBG normalBlack noTopBorder ubuntu active" href="#" data-login-method="userCredentials"> 
    <img src="/jmvc/avanzabank/images/inloggningsuppgifter_ic.svg" class="loginTypeIcon" alt="Inloggningsuppgifter" title="Inloggningsuppgifter"> 
    Användarnamn &amp; lösenord <span class="arrow fRight"></span> 
    </a> 
    <div class="toggleBarContent noPaddingTop "> 
    <div class="messageWrapper formLogin"></div> 
    <form autocomplete="off" class="loginForm clearFix" method="POST" action="/ab/noop"> 
     <input placeholder="Användarnamn" type="text" name="j_username" autocapitalize="none"> 
     <input placeholder="Lösenord" type="password" name="j_password"> 
     <button class="focusBtn loginButton marginTop5px marginBottom15px errorToolTipPlacement fRight" type="submit" disabled="disabled">Logga in</button> 

     <a class="marginTop4px defaultSize plcLink" href="/glomt-uppgift.html">Glömt lösenord eller användarnamn?</a> 
    </form> 
    </div> 
</div>

然而，當我試圖提交我得到：

Traceback (most recent call last): 
    File "scrap_mec.py", line 91, in <module> 
    res = br.submit() 
    File "/usr/lib/python2.7/dist-packages/mechanize/_mechanize.py", line 541, in submit 
    return self.open(self.click(*args, **kwds)) 
    File "/usr/lib/python2.7/dist-packages/mechanize/_mechanize.py", line 530, in click 
    request = self.form.click(*args, **kwds) 
AttributeError: 'NoneType' object has no attribute 'click'

我認爲你仍然必須使用select_form方法，以便瀏覽器知道你要提交的表單
