python模拟登陆csdn，实测登陆正常

准备在csdn上发布文章，但是自己有个人博客网站，文章同时发布个人网站和csdn操作发布两边操作太过麻烦，于是想到了模拟登陆，通过模拟登陆csdn网站后，再进行推送文章内容到csdn上。

1、第一步是抓取到对应的登陆地址和相关传输的信息。

csdn的登陆地址是https://passport.csdn.net/account/verify，

可以在POST的信息中查看到对应的登陆信息

username:weixin_42740498
password:你的密码
lt:LT-52961-eMo02Bz4tlj3wQzDMSDA2dsqE
execution:e15s2
_eventId:submit

除了对应的登陆账号和密码外还能才开到lt，execution，_eventId这个结果参数,参考之前写过的python模拟登陆csdn，是在登陆的时候from提交中带的参数，可以直接在页面或者获取

 <!-- 该参数可以理解成每个需要登录的用户都有一个流水号。只有有了webflow发放的有效的流水号，用户才可以说明是已经进入了webflow流程。否则，没有流水号的情况下，webflow会认为用户还没有进入webflow流程，从而会重新进入一次webflow流程，从而会重新出现登录界面。 -->
                    <input type="hidden" name="lt" value="LT-2435240-Nu7f3yuoN1eMZvcAmDsRmPgq17xIMd" />
                    <input type="hidden" name="execution" value="e2s1" />
                    <input type="hidden" name="fkid" id="fkid" value="" />
                    <input type="hidden" name="_eventId" value="submit" />
                    <input class="logging" accesskey="l" value="登 录" tabindex="6" type="button" />
					<!-- data-kuick='{"act":"csdn05","desc":"直接登录"}' -->

测试只获取这几个参数还是登陆存在异常，查看了一下登陆的时候的cookie值，发现其中几个cookie都是固定不变的

"UserName":"weixin_42740498",
"UserInfo":"FK6HcljRDYdAyejwq9BQ558Z4N5YHLP4UXz3RVLRtNUVa5irrsuv558Z4N5YHLP4UXz3RVLRtNU5uH2hewDCAS6%2BaDo1eyiQx%2FWlsARwnvVC8rg5SyXoPql%2BZ12KxAo%2FKqmjShy6U1b9DQQXzKE8HKZOj5Cay0%2Bew%3D%3D",
"UserNick":"%E5%AD%A4%7%A1%E7%e%E5%B7%A1%E7%A4%BC",
"UserToken":"FK6HcljRDYdAyejwq9BQQ%2B1Pql%2BZ12KxAo%2FKqmjSv558Z4N5YHLP4UXz3RVLRtNU5uH2hewDCAS6%2BaDo1eyiQx%2FWlsARwnvVC8rg5SyXoPql%2BZ12KxAo%2FKqmjShy6U1bubjIKZ4i5P9pepVRmPmIKdCZhxA6KuC%2Fyuola8bAelGWgqOOCmrfEW7X%2BFxAPRi5"

将对应的登陆账号信息和不变的cookie存到user.ini中方便后面模拟登陆调用。

实现模拟登陆源码如下，在访问其他页面的时候直接用session去进行请求对应页面即可

import requests,os
from bs4 import BeautifulSoup
from http import cookiejar

login_url='https://passport.csdn.net/account/verify'
headers={ 'User-Agent':'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/31.0.1650.63 Safari/537.36', 'Accept-Encoding': 'gzip, deflate','Connection': 'keep-alive','Accept': '*/*'}

def get_setting():
	try:
		with open(os.path.abspath('.') + '/user.ini', 'r') as f:
			u_name = f.readline().strip()
			u_password = f.readline().strip()
			cookies = eval(f.readline().strip())
	except IOError:
		print("user.ini不存在,请检查!")
		exit()
	return(u_name, u_password,cookies)

def get_lt():
	response = requests.post(login_url)
	# f = open('csdnlogin.html', 'w')
	# f.write(response.text)
	# f.close()
	soup = BeautifulSoup(response.text, "html.parser")
	for input in soup.form.find_all("input"):
		if input.get("name") == "lt":
			lt = input.get("value")
		if input.get("name") == "execution":
			execution = input.get("value")
	return(lt,execution)

def get_session():
		global session
		session = requests.Session()
		(lt,execution) = get_lt()
		(u_name, u_pwd, cookies) = get_setting()
		c = requests.cookies.RequestsCookieJar()
		data = {
		"username":u_name,
		"password":u_pwd,
		"lt":lt,
		"execution":execution,
		"_eventId":"submit"
		}
		for k, v in cookies.items():
			c.set(k, v)
		session.cookies.update(c)
		#print(session.cookies)
		headers={ 'User-Agent':'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/31.0.1650.63 Safari/537.36', 'Accept-Encoding': 'gzip, deflate','Connection': 'keep-alive','Accept': '*/*'}
		try:
			session.post(login_url, headers=headers,data=data)
			# html=session.post('https://my.csdn.net',headers=headers).text
			# print(session.cookies)
			# f = open('csdn.html', 'w')
			# f.write(html)
			# f.close()
			print('ok')

		except Exception as e:
			raise e
