我对这个程序的想法是有一个简单的(据说)脚本来监视现在几点，当它在特定时间范围内(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网页内容过滤功能。
我以为我会从简单的开始，只是弄清楚登录网站和阻止网站的命令，然后再担心时间的监控等。但遗憾的是，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。这是除了机械化之外我唯一能找到的(我找不到合适的文档，但也许我只是没有在正确的地方寻找)
这是我的代码(好吧，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()
这就是我的问题开始的地方。 在最后一个 b.showforms() 上我得到一个错误:
Traceback (most recent call last):
File "<pyshell#43>", line 1, in <module>

请您参考如下方法:
是的，python 的斜纹 Material 并不是世界上最好的文档。我认为您基本上可以忘记“get_browser”这些东西。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()
