我正在尝试从发送POST请求中获取HTML页面：import httplib

import urllib

import urllib2

from BeautifulSoup import BeautifulSoup

headers = {

'Host': 'digitalvita.pitt.edu',

'Connection': 'keep-alive',

'Content-Length': '325',

'Origin': 'https://digitalvita.pitt.edu',

'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_4) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/21.0.1180.89 Safari/537.1',

'Content-type': 'application/x-www-form-urlencoded; charset=UTF-8',

'Accept': 'text/javascript, text/html, application/xml, text/xml, */*',

'Referer': 'https://digitalvita.pitt.edu/index.php',

'Accept-Encoding': 'gzip,deflate,sdch',

'Accept-Charset': 'ISO-8859-1,utf-8;q=0.7,*;q=0.3',

'Cookie': 'PHPSESSID=lvetilatpgs9okgrntk1nvn595'

}

data = {

'action': 'search',

'xdata': 'familyName1000001dAll',

'request': 'search'

}

data = urllib.urlencode(data)

print data

req = urllib2.Request('https://digitalvita.pitt.edu/dispatcher.php', data, headers)

response = urllib2.urlopen(req)

the_page = response.read()

soup=BeautifulSoup(the_page)

print soup

有人能告诉我怎么做吗？
