刚学Python,用Requests试了一下登陆V2EX并对某个主题发表评论。评论成功。但是抛出异常，评论失败时（前后两条评论内容一样时,V2ex会阻止评论），也抛出一样的异常。

想请教这个异常的原因

代码和异常如下

代码

# coding=utf-8
import requests
from bs4 import BeautifulSoup as bs

s = requests.Session()
headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.95 Safari/537.36',
    'Origin': 'http://www.v2ex.com',
    'Referer': 'http://www.v2ex.com/signin',
    'Host': 'www.v2ex.com',
}

r = s.get('http://www.v2ex.com/signin', headers=headers)
soup = bs(r.content)
once = soup.find('input', {'name': 'once'})['value']
print 'login once = ' + once

login_data = {'u': 'Registering', 'p': '1111111111', 'once': once, 'next': '/'}
s.post('https://www.v2ex.com/signin', login_data, headers=headers)

v_topic = s.get('https://www.v2ex.com/t/185169', headers=headers)
soup = bs(v_topic.content)
once = soup.find('input', {'name': 'once'})['value']
print 'title once = ' + once


comment_data = {'content': 'I am a sexy robot','once': once}
s.post('https://www.v2ex.com/t/185169', comment_data, headers=headers)

异常

>>> 
login once = 50558
title once = 59608

Connection aborted
估计是防火墙限制了频繁的操作，就像快速连续刷新某个页面那样？

怎么我用楼主的程序出现错误：

@stronger
代码中的账号密码有改过来？
我用的是python2.7.9
，

[stronger]

@Registering 改成我自己的了，我的是2.7.8，还是不行呢

[Registering]

@stronger 你没安装Requests和BeautifulSoup4这两个第三方库吧

[stronger]

@Registering 安装了呀，奇怪呢！！！

[stronger]

@Registering 还是之前那个错误什么SSL错误

[HappyTrail]

把楼主代码里的https都换成http之后就成功了 - -
post相同内容也没有报异常 返回里有"创建新回复过程中遇到一些问题：你上一条回复的内容和这条相同" (

[stronger]

@Registering 请问一下，post里面的once数据是什么呀？

[Registering]

@stronger
你要学会用chrome的控制台，并查看每次点击链接发送请求时的报文
你会发现每次登陆不止发送账号密码，还有一个once字符串，该字符串是每次随机生成的，
