python - 获取 Bing 的表单名称

Question

使用 Python 2.7.x 和 Mechanize，我试图获取 Bing 的表单名称并进行搜索:

import mechanize

AGENT = mechanize.Browser()
BING = "http://www.bing.com"

def bing_search(query):
    AGENT.open(BING)
    for form in AGENT.forms():
        print form
    AGENT.select_form(name="q")
    AGENT.form["q"] = query
    data = AGENT.submit()

输出如下所示:

C:\Users\z-perkins-thomas\Documents\bin\python\some-type-of-scanner>python querymine.py
<GET http://www.bing.com/search application/x-www-form-urlencoded
  <TextControl(q=)>
  <SubmitControl(go=) (readonly)>
  <HiddenControl(qs=ds) (readonly)>
  <HiddenControl(form=QBLH) (readonly)>>
Traceback (most recent call last):
  File "querymine.py", line 4, in <module>
    bing_search("test")
  File "C:\Users\z-perkins-thomas\Documents\bin\python\some-type-of-scanner\bin\harvest\search_engines\__init__.py", line
55, in bing_search
    AGENT.select_form(name="q")
  File "C:\Python27\lib\site-packages\mechanize\_mechanize.py", line 524, in select_form
    raise FormNotFoundError("no form matching "+description)
mechanize._mechanize.FormNotFoundError: no form matching name 'q'

如您所见，列出了表单名称，但是尝试任何列出的表单名称都不起作用并输出相同的问题，我在这里做错了什么？

Answer 1

您似乎正在尝试选择名称为 q 的表单这在 bing.com 上不存在。但是，有一个具有该名称的输入字段。

你应该像这样使用它:

def bing_search(query):
    AGENT.open('http://www.bing.com/')
    AGENT.select_form(nr=0)
    AGENT.form['q'] = query
    data = AGENT.submit()
