python机械化不识别形式

Question

我正在尝试在此页面上登录。

br = mechanize.Browser(factory=mechanize.RobustFactory())
br.set_cookiejar(cj)
current_page = br.open(LOGIN_URL)
soup = BeautifulSoup(current_page.get_data())
current_page.set_data(soup.prettify())
br.set_response(current_page)
 print soup.findAll('form')
 assert br.viewing_html()
 for f in br.forms():
     print f.name

，但是即使美丽的套件完美地找到了表格，它也不会为表格打印。有人有任何想法吗？

Answer 1

类似的东西会起作用：

    from bs4 import BeautifulSoup
    import mechanize
    import cookielib
    br = mechanize.Browser()
    cj = cookielib.LWPCookieJar()
    br.set_cookiejar(cj)
    host = 'https://order.papajohns.com/secure/signin/frame.html?destination=http%3a%2f%2forder.papajohns.com%2findex.html%3fsite%3dWEB%26dclid%3d%2525n-2543611-4121096-71899047-246709315-0%26esvt%3d336192-GOUSe339376223%26esvq%3dpapa%2520johns%26esvadt%3d999999-0-3934985-1%26esvcrea%3d41751468573%26esvplace%26esvd%3dc%26esvaid%3d30536%26gclid%3dCI2psOHqtbwCFRPxOgodr0gAAg'
    br.addheaders = [('User-agent', 'Firefox')]
    br.open(host)
    br.form = list(br.forms())[0]
    br.form['userName'] = username
    br.form['pwd'] = password
    submit = br.submit()
    code = response.read()
    soup = BeautifulSoup(code)
