我想下载一个页面，填写表单并提交它。我喜欢python并碰到机械化。我可以成功下载网页，验证页面中有2个表单，但即使我可以确认机械化下载的网页数据明确包含第二个表单，机械化不会识别第二个表单（方法POST）。因此，我甚至无法修改这些值并提交我感兴趣的表单。我在OS X 10.6.8上的Python 2.6.1上。任何建议非常感谢。
我的代码
import mechanize
br = mechanize.Browser()
br.set_handle_robots(False) # no robots
br.set_handle_refresh(False) # can sometimes hang without this
br.addheaders = [('User-agent', 'Mozilla/6.0 (X11; U; i686; en-US; rv:1.9.0.1) Gecko/2008071615 OS X 10.2 Firefox/3.0.1')]
url = 'http://www.abcd.com/test.html'
response = br.open(url)
我可以验证使用response.read（）或GET_DATA（），有两种形式，如下面
<form id="lookupFormX" action="/lookup/" onSubmit="return submitLookupForm('lookupForm', 'download');" method="GET">
<label style="font-weight:normal; font-size:85%; margin-right:5px;">View a Site Report </label>
<input type="hidden" name="facet" style="margin-right:2px; font-weight:normal; font-size:85%;" value="sitereport" readonly/>
<input style="margin-right:2px; font-weight:normal; font-size:85%;" name="q" type="text" id="railtext_v11pt" value="e.g. yahoo.com"
onfocus="clearDefaultNote(this,'e.g. yahoo.com');"
onblur="addDefaultNote(this,'e.g. yahoo.com');" />
<a style="margin-right:10px;" href="#" onclick="submitLookupForm('lookupFormX');"><img src="/images/nav_right.gif" /></a>
</form>
<br>

</FORM>
仅机械化显示以下内容：
Form name: None
<GET http://www.test.com/lookup/ application/x-www-form-urlencoded
<HiddenControl(facet=sitereport) (readonly)>
<TextControl(q=e.g. yahoo.com)>>
当我用下面的代码
for form in br.forms():
print "Form name:", form.name
print form
我的问题： - 我如何才能访问第二个表单？ （使用NR = 1给了我一个错误）
编辑：
我想这一个版本的太多，同样的结果，第二个表格将不会显示出来：
request = mechanize.Request(url)
request.add_header("User-agent", "Mozilla/6.0 (X11; U; i686; en-US; rv:1.9.0.1) Gecko/2008071615 OS X 10.2 Firefox/3.0.1")
response = mechanize.urlopen(request)
forms = mechanize.ParseResponse(response, backwards_compat=False)
response.close()
for form in forms:
print form

我也试图改变我的代码看起来像这样：
# 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)
# Follows refresh 0 but not hangs on refresh > 0
br.set_handle_refresh(mechanize._http.HTTPRefreshProcessor(), max_time=1)
br.addheaders = [
('Cookie','mbox=PC#1327356910232-537677#1410633293|check#true#1347561353|session#1347561287712-498080#1347563153; s_cc=true; s_sq=%5B%5BB%5D%5D; s_nr=1347561671754-Repeat'),\

我的M拾起头值y浏览器并尝试将它们插入机械化浏览器实例中。然而，我只能看到这种形式。
是的，你是对的。该网址是http://www.siteadvisor.com/userfeedback.html – JPK
