from bs4 import BeautifulSoup

import urllib

import http.cookiejar
import string
import re

referurl="http://www.iteye.com"# 
hosturl = "http://www.iteye.com/login" #自己填写

##########################session获取
#设置一个cookie处理器,它负责从服务器下载cookie到本地,并且在发送请求时带上本地的cookie
cj = http.cookiejar.LWPCookieJar()
cookie_support = urllib.request.HTTPCookieProcessor(cj)
opener = urllib.request.build_opener(cookie_support, urllib.request.HTTPHandler)
urllib.request.install_opener(opener)

#构造header,一般header至少要包含一下两项。这两项是从抓到的包里分析得出的。
headers = {'User-Agent' : 'Mozilla/5.0 (Windows NT 6.1; WOW64; rv:43.0) Gecko/20100101 Firefox/43.0',
           'Referer' : hosturl}
#打开登录主页面(他的目的是从页面下载cookie,这样我们在再送post数据时就有cookie了,否则发送不成功)
request = urllib.request.Request(hosturl, None, headers)
response = urllib.request.urlopen(request)
htmldata = response.read()
html_doc=htmldata.decode('utf-8')
#print(htmldata.decode('utf-8'))
##########################session获取完毕,以下的操作,在一个session中进行。

soup = BeautifulSoup(html_doc,"html.parser")
tokenfind=soup.find('input', {'name': 'authenticity_token'}).get('value')#一个验证串,同一个session周期内,不会改变

print(tokenfind)


username=input('输入用户名:');
passinput=input('输入密码:');

#构造Post数据,从抓的包里分析得出的。
postData = {'name': username,'password':passinput,'authenticity_token':tokenfind}
postData = urllib.parse.urlencode(postData).encode('utf-8')
headers = {'User-Agent' : 'Mozilla/5.0 (Windows NT 6.1; WOW64; rv:43.0) Gecko/20100101 Firefox/43.0',
