Python Mechanize select_form() - ParseError : OPTION outside of SELECT

转载作者：太空狗更新时间：2023-10-30 01:29:58

我正在使用 Python 2.7 和 Mechanize 2.5。我正在尝试使用 select_form() 方法，但出现以下错误:

  File "C:\Python27\lib\site-packages\mechanize\_mechanize.py", line 499, in select_form
    global_form = self._factory.global_form
  File "C:\Python27\lib\site-packages\mechanize\_html.py", line 544, in __getattr__
    self.forms()
  File "C:\Python27\lib\site-packages\mechanize\_html.py", line 557, in forms
    self._forms_factory.forms())
  File "C:\Python27\lib\site-packages\mechanize\_html.py", line 237, in forms
    _urlunparse=_rfc3986.urlunsplit,

    _urlunparse=_urlunparse,
  File "C:\Python27\lib\site-packages\mechanize\_form.py", line 982, in _ParseFileEx
    fp.feed(data)
  File "C:\Python27\lib\site-packages\mechanize\_form.py", line 759, in feed
    _sgmllib_copy.SGMLParser.feed(self, data)
  File "C:\Python27\lib\site-packages\mechanize\_sgmllib_copy.py", line 110, in feed
    self.goahead(0)
  File "C:\Python27\lib\site-packages\mechanize\_sgmllib_copy.py", line 144, in goahead
    k = self.parse_starttag(i)
  File "C:\Python27\lib\site-packages\mechanize\_sgmllib_copy.py", line 302, in parse_starttag
    self.finish_starttag(tag, attrs)
  File "C:\Python27\lib\site-packages\mechanize\_sgmllib_copy.py", line 347, in finish_starttag
    self.handle_starttag(tag, method, attrs)
  File "C:\Python27\lib\site-packages\mechanize\_sgmllib_copy.py", line 387, in handle_starttag
    method(attrs)
  File "C:\Python27\lib\site-packages\mechanize\_form.py", line 736, in do_option
    _AbstractFormParser._start_option(self, attrs)
  File "C:\Python27\lib\site-packages\mechanize\_form.py", line 481, in _start_option
    raise ParseError("OPTION outside of SELECT")
ParseError: OPTION outside of SELECT

这是我的代码:

cj = cookielib.LWPCookieJar()
br = mechanize.Browser()
br.set_cookiejar(cj)
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)
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("website_url_which_i_will_not_share")
br.select_form(nr=0)

以下是我打开的网页html中的表单部分

<html lang="en-us" xml:lang="en-us" xmlns="http://www.w3.org/1999/xhtml">
    <head> I omitted this section </head>
    <body class="login">
        <div id="container">
            <div id="header" style="background-color: #13397A;">
            <div id="content" class="colM">
                <div id="content-main">
                    <form id="login-form" method="post" action="/admin/">
                        <div style="display:none">

                        <div class="form-row">
                            <label class="required" for="id_username">Username:</label>
                            <input id="id_username" type="text" maxlength="30" name="username">
                        </div>
                        <div class="form-row">
                            <label class="required" for="id_password">Password:</label>
                            <input id="id_password" type="password" name="password">
                            <input type="hidden" value="1" name="this_is_the_login_form">
                            <input type="hidden" value="/admin/" name="next">
                        </div>
                        <div class="submit-row">
                            <label>&nbsp;</label>
                            <input type="submit" value="Log in">
                        </div>
                    </form>
                    <script type="text/javascript">
                </div>
                <br class="clear">
            </div>
            <div id="footer"></div>
        </div>
        <script type="text/javascript">
    </body>
</html>

我已经在 stackoverflow 和谷歌上对此进行了研究，但找不到类似的问题，甚至找不到此错误的描述。

如果有人能告诉我这个错误是什么意思并帮助我找出问题所在，我将不胜感激。

谢谢

编辑:我一直在做大量的表单提交工作，除了这个以外，每个网站都运行良好。它是一个数据库 API，我正试图从中抓取数据。

最佳答案

我遇到了同样的问题(不幸的是还没有解决)，我发现了这段有趣的代码，它可能会有所帮助

来自 http://comments.gmane.org/gmane.comp.python.wwwsearch.general/1991 (参见 archive.org version)

import   mechanize
from   BeautifulSoup   import  BeautifulSoup  

class SanitizeHandler(mechanize.BaseHandler):
    def http_response(self, request, response):
        if not hasattr(response, "seek"):
            response = mechanize.response_seek_wrapper(response)
        #if    HTML   used   get   it though  a    robust  Parser    like  BeautifulSoup

        if response.info().dict.has_key('content-type') and ('html' in response.info().dict['content-type']):
            soup = BeautifulSoup(response.get_data())
            response.set_data(soup.prettify())
        return response

br = mechanize.Browser()
br.add_handler(SanitizeHandler())

# Now    you get    good   HTML

这应该覆盖 http_response 方法并“清理”您的 html。
