Python//Mechanize//找不到表格

Question

我正在使用 Mechanize 查找和提交表单。代码如下所示:

url = "THIS_IS_A_LINK"
br = mechanize.Browser()
br.set_handle_robots(False)
br.addheaders=[('User-agent','chrome')]
br.open(url)
htmltext = br.open(url).read()
print htmltext

br.select_form(name="genericsearch_param.fulltext")
br["q"] = "metal"
res = br.submit()
content = res.read()
with open("mechanize_results.html", "w") as f:
   f.write(content) 

HTML 看起来像这样:

<form method="get" action="/WHAT_SO_EVER" accept-charset="utf-8" class="clearfix" style="display: inline;"><input type="hidden" name="session.sessionid" value="sdfosdfosdf3482374892hsdfanw9023qjh"><input type="hidden" name="global_data.designmode" value="xf"><div class="clearfix">
                                <div class="left"><label for="genericsearch_param.fulltext">Searchterm</label><input type="text" class="text" id="genericsearch_param.fulltext" name="genericsearch_param.fulltext" value=""></div> <div class="right"><label for="genericsearch_param.part_id">Searcharea</label><select id="genericsearch_param.part_id" name="genericsearch_param.part_id">

我不想使用 Selenium，因为它需要大量的浏览器打开和关闭。为什么 Mechanize 找不到表格？

Answer 1

只需选择p上的第一个表单

br.select_form(nr=0)

你确定提交按钮有效吗？:

submit_response = br.submit(name='action') 或 submit_response = br.submit(label='action')

您可能会混淆您要选择的表单。
