前几日突然发现，好好的签到功能不能使用了，分析了下v2ex的源码，发现原来是网站登录的时候用户名和密码两个input的name改成自动生成的了，遂有了如下的代码：
#/usr/bin/python
# -*- coding : utf-8 -*-
from bs4 import BeautifulSoup
import requests
import os
username = 'xxx' # your v2ex username
password = 'xxx' # your v2ex password
login_url = 'https://v2ex.com/signin'
home_page = 'https://www.v2ex.com'
mission_url = 'http://www.v2ex.com/mission/daily'
UA = "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/33.0.1750.152 Safari/537.36"
headers = {
"User-Agent" : UA,
"Host" : "www.v2ex.com",
"Referer" : "https://www.v2ex.com/signin",
"Origin" : "https://www.v2ex.com"
}
v2ex_session = requests.Session()
def make_soup(url,tag,name):
page = v2ex_session.get(url,headers=headers,verify=True).text
soup = BeautifulSoup(page)
soup_result = soup.find(attrs = {tag:name})
# print soup_result
return soup_result
def getRespone(url):
return v2ex_session.get(url,headers=headers,verify=True).text
def _soup(text, tag, name):
soup = BeautifulSoup(text)
soup_result = soup.find(attrs = {tag:name})
# print soup_result
return soup_result
def _soup_all(text, tag, name):
soup = BeautifulSoup(text)
soup_result = soup.find_all(attrs = {tag:name})
# print soup_result
return soup_result
# get login parameter once_value
response = getRespone(login_url)
once_value = _soup(response,'name','once')['value']
print once_value
# get login form' user and password name
formNames = _soup_all(response,'class','sl')
# print formNames
print formNames[0]['name']
print formNames[1]['name']
post_info = {
formNames[0]['name'] : username,
formNames[1]['name'] : password,
'once' : once_value
}
resp = v2ex_session.post(login_url,data=post_info,headers=headers,verify=True)
# get final sign url
short_url = make_soup(mission_url, 'class', 'super normal button')["onclick"]
print short_url
# os._exit(0)
first_quote = short_url.find("'")
last_quote = short_url.find("'", first_quote+1) #str.find(str, beg=0 end=len(string))
final_url = home_page + short_url[first_quote+1:last_quote]
print(final_url)
# start sign
page = v2ex_session.get(final_url,headers=headers,verify=True).content
suceessful = make_soup(mission_url, 'class', 'fa fa-ok-sign')
if suceessful:
print ("Sucessful.")
else:
print ("Something wrong.")
