我对这个程序的想法是有一个简单的（假设是）脚本来监控现在是什么时间，当它在某个时间范围内（例如早上 6 点到晚上 7 点）时，它会导航到 opendns.com 并阻止某些网站使用 web 内容过滤功能。

我以为我会从简单的开始，只需找出登录网站和阻止网站的命令，然后担心时间监控等。但可悲的是，我也遇到了麻烦。

我正在使用http://twill.idyll.org/但不确定这是否是个好主意。这是除了 mechanize 之外我能找到的唯一一个（我找不到正确的文档，但也许我只是没有在正确的地方寻找）

这是我的代码（嗯，它还不是真正的代码。只是 Python Shell 的命令列表）：

from twill import get_browser
from twill.commands import *

username = "username@email.com" # email for opendns
password = "thisisthepassword" # password for opendns
b = get_browser()

b.go("https://dashboard.opendns.com/")
b.showforms()

fv("2", "username", username)
fv("2", "password", password)
showforms()

submit("sign-in")

b.showforms()

b.go ("https://dashboard.opendns.com/settings/*MYNETWORKID*/content_filtering") # I replaced my network ID due to privacy reasons but this is basically the URL to the web content filtering page on OpenDNS for a network

b.showforms()

现在这就是我的问题开始的地方。在最后一个 b.showforms() 我收到一个错误：

Traceback (most recent call last):
  File "<pyshell#43>", line 1, in <module>
    b.showforms()
  File "C:\Python27\lib\site-packages\twill-0.9-py2.7.egg\twill\browser.py", line 225, in showforms

是的，python 的斜纹布并不是世界上最好的文档。我认为您基本上可以忘记“get_browser”的东西。这样斜纹布的东西对我来说更清楚一点：

import twill.commands as twill

username = "username@email.com" # email for opendns
password = "thisisthepassword" # password for opendns

twill.go("https://dashboard.opendns.com/")
twill.showforms()

twill.fv("2", "username", username)
twill.fv("2", "password", password)
twill.showforms()

twill.submit("sign-in")

twill.showforms()

twill.go ("https://dashboard.opendns.com/settings/*MYNETWORKID*/content_filtering") # I replaced my network ID due to privacy reasons but this is basically the URL to the web content filtering page on OpenDNS for a network

twill.showforms()
