如何从urllib提交此表单作为我当前的代码：

import cookielib
import urllib
import urllib2


# Store the cookies and create an opener that will hold them
cj = cookielib.CookieJar()
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))

# Add our headers
opener.addheaders = [('User-agent', 'RedditTesting')]

# Install our opener (note that this changes the global opener to the one
# we just made, but you can also just call opener.open() if you want)
urllib2.install_opener(opener)

# The action/ target from the form
authentication_url = 'https://tatts.com/tattersalls'

# Input parameters we are going to send
payload = {
  '_EVENTTARGET:' ''
  '__EVENTARGUMENT:' ''
  '__VIEWSTATE:' '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'

  'ctl00$ctl01$navLgnMember$Password:' '########'
  'ctl00$ctl01$navLgnMember$Login:'

  }

# Use urllib to encode the payload
data = urllib.urlencode(payload)

# Build our Request object (supplying 'data' makes it a POST)
req = urllib2.Request(authentication_url, data)

# Make the request and read the response
resp = urllib2.urlopen(req)
contents = resp.read()

print (resp)

是一种公平的方式，可以提交到网络的正确部分。

我试图登录并创建一个会话，然后能够将更多的webform数据发布到网站的其他部分。

提前致谢。

根据SO的另一篇文章：Mechanize and Javascript，你有不同的选择，从在Python中模拟javascript脚本正在做什么，到使用完整的Selenium及其Python绑定。

如果您尝试继续使用简单的Python方式，我强烈建议您使用网络间谍（例如优秀的wireshark）来分析通过真实浏览器成功登录的实际内容和发送方式，以及您的内容Python模拟发送。
