使用python自动按下“提交”按钮

Twill 是一种简单的网页浏览脚本语言。它碰巧是运动A python api .

斜纹实质上是一个薄壳周围的机械包装。所有twill命令都在commands.py文件中实现,py parsing完成对输入的解析并将其转换为python命令的工作(请参见parse.py)。交互式shell工作和readline支持通过命令模块(来自标准的python库)实现。

以上链接单据的“按”提交示例:

from twill.commands import go, showforms, formclear, fv, submit

go('http://issola.caltech.edu/~t/qwsgi/qwsgi-demo.cgi/')
go('./widgets')
showforms()

formclear('1')
fv("1", "name", "test")
fv("1", "password", "testpass")
fv("1", "confirm", "yes")
showforms()

submit('0')

我建议你用 mechanize . 以下是他们页面中的代码片段,显示了如何提交表单:

import re
from mechanize import Browser

br = Browser()
br.open("http://www.example.com/")
# follow second link with element text matching regular expression
response1 = br.follow_link(text_regex=r"cheese\s*shop", nr=1)
assert br.viewing_html()
print br.title()
print response1.geturl()
print response1.info()  # headers
print response1.read()  # body
response1.close()  # (shown for clarity; in fact Browser does this for you)

br.select_form(name="order")
# Browser passes through unknown attributes (including methods)
# to the selected HTMLForm (from ClientForm).
br["cheeses"] = ["mozzarella", "caerphilly"]  # (the method here is __setitem__)
response2 = br.submit()  # submit current form

# print currently selected form (don't call .submit() on this, use br.submit())
print br.form

您很少希望实际“按下提交按钮”,而不是直接向处理程序资源发出GET或POST请求。查看表单所在的HTML,查看它提交到哪个URL的参数,以及它是get还是post方法。您可以用urllib(2)很容易地形成这些请求。
