用python提交表单 [英] Submitting form with python

问题描述

我需要在我的python脚本中解析HTML。然而，要在我的浏览器中访问我需要的页面，请单击单选按钮并提交表单。那么，我如何使用python提交表单并获取呈现的html？谢谢，我会很感激任何帮助。

我在谈论的形式：

 < form id =acmethod =post> 
< input type =radioid =aname =avalue =2onchange =document.getElementById（'ac'）。submit（）;检查= 检查 > 
< input type =radioid =aaname =avalue =1onchange =document.getElementById（'ac'）。submit（）;> 
< input type =radioid =aaaname =avalue =0onchange =document.getElementById（'ac'）。submit（）;> 
< / form>

一个单选按钮以name = value的形式发送它的数据，在这种情况下a = 2。 Python URLLib / URLLib2 POST ：

  import urllib 
 import httplib 
 
 server ='myserver.com'
 get_data ='/ link / with / get / data.php？test = 1'
 
 data = urllib.urlencode（{'a'：2}）
h = httplib.HTTPConnection（'enfenion.com'）
 headers = {Content-键入：application / x-www-form-urlencoded，Accept：text / plain} 
 h.request（'POST'，get_data，data，headers）
r = h。 getresponse（）
 print r.read（）
  

I need to parse HTML in my python script. However to get to the page I need, in my browser, to click radio button and submit form. So, how can I submit form with python and get rendered html back? Thanks, I would appreciate any help.

The form I'm talking about:

<form id="ac" method="post">
      <input type="radio" id="a" name="a" value="2" onchange="document.getElementById('ac').submit();" checked="checked">
      <input type="radio" id="aa" name="a" value="1" onchange="document.getElementById('ac').submit();">
      <input type="radio" id="aaa" name="a" value="0" onchange="document.getElementById('ac').submit();">
</form>

解决方案

You can use urllib for this: http://docs.python.org/2.7/library/urllib.html

A radio button sends its data as name=value, in this case a=2.

Modified example from Python URLLib / URLLib2 POST :

import urllib
import httplib

server='myserver.com'
get_data='/link/with/get/data.php?test=1'

data = urllib.urlencode({'a': 2})
h = httplib.HTTPConnection('enfenion.com')
headers = {"Content-type": "application/x-www-form-urlencoded", "Accept": "text/plain"}
h.request('POST', get_data, data, headers)
r = h.getresponse()
print r.read()
