http协议是无状态的，也就是每个请求都是独立的。那么登录后的一系列动作，都需要用cookie来验证身份是否是登录状态，为了高效的管理会话，保持会话，于是就有了session。

session简介

　　session是一种管理用户状态和信息的机制，与cookies的不同的是，session的数据是保存在服务器端。说的明白点就是session相当于一个虚拟的浏览器，在这个浏览器上处于一种保持登录的状态。

session登录

格式：

# session 用法|  Basic Usage::|  |    >>> import requests|    >>> s = requests.Session()|    >>> s.get('https://httpbin.org/get')|    <Response [200]>|  |  Or as a context manager::|  |    >>> with requests.Session() as s:|    >>>     s.get('https://httpbin.org/get')|    <Response [200]>

1.举个例子，模拟百度登录场景

2.查看登录后百度账号的cookies值，经过观察发现是由”BAIDUID“和"BDUSS"

3.导入requests模块，使用session()函数

4.携带cookies进行请求，通过返回内容，判断是否登录成功。

# coding:utf-8
import requests
# 保持登录状态
s = requests.session()
url = 'https://www.baidu.com/'
# 请求头
headers = {"User-Agent":"Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/69.0.3497.81 Safari/537.36"
}
r = s.post(url,headers=headers)
# 查看的cookies值
cooks = {"BDUSS":"xxxxxxx","BAIDUID":"XXXXXXXX"
}
# 添加登录所携带的cookies
c = requests.cookies.RequestsCookieJar()
c.set("BDUSS",cooks["BDUSS"])
c.set("BAIDUID",cooks["BAIDUID"])
s.cookies.update(c)
# 判断是否登录成功
r2 = s.get(url,headers=headers)
if '我在谁身旁' in r2.text:print('登录成功')
else:print("登录失败")执行结果：登录成功

这个时候就可以做一些登录过后的操作。

session模拟浏览器，浏览器中登录状态，只要浏览器不退出，就可以继续做其他的操作了。

自动写博客

我们先理下书写的思路：

1.通过request访问博客园；

2.通过session保存cookies；

3.携带保存的cookies进行请求写博客的接口

4.编写博客内容，进行保存，发博客

获取登录cookies

1.通过fiddler\F12进行抓取未登录的cookies值

2.再次抓取Fiddler\F12进行抓取登录后的cookies值

3.把cookies放到session中

# coding:utf-8
import requests
import urllib3
from bs4 import BeautifulSoup
urllib3.disable_warnings()
s = requests.session()
s.verify = False  # 全局的
url = 'https://passport.cnblogs.com/user/signin'headers = {"User-Agent":"Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/69.0.3497.81 Safari/537.36"
}
r = s.get(url,headers=headers)
cooks = {".Cnblogs.AspNetCore.Cookies":"XXXXXXXX",".CNBlogsCookie":"XXXXXX"
}
c = requests.cookies.RequestsCookieJar()
c.set(".CNBlogsCookie", cooks[".CNBlogsCookie"])  # 登陆有效的cookies
c.set(".Cnblogs.AspNetCore.Cookies", cooks[".Cnblogs.AspNetCore.Cookies"])
s.cookies.update(c)
url1 = "https://i.cnblogs.com/EditPosts.aspx?opt=1"
r1 = s.get(url1)
if "博客后台管理" in r1.text:print("登录成功！")

抓取写博客接口

1.抓取编写博客接口，获取编写内容，查看Raw获取接口内容

2.把这些值通过字典的形式进行编写如：{“name”：“value”}

body = {"__VIEWSTATE":"","__VIEWSTATEGENERATOR":"FE27D343","Editor$Edit$txbTitle":"编辑草稿","Editor$Edit$EditorBody":"这是编辑草稿的内容","Editor$Edit$Advanced$ckbPublished":"on","Editor$Edit$Advanced$chkDisplayHomePage":"on","Editor$Edit$Advanced$chkComments":"on","Editor$Edit$Advanced$chkMainSyndication":"on","Editor$Edit$Advanced$txbEntryName":"","Editor$Edit$Advanced$txbExcerpt":"","Editor$Edit$Advanced$txbTag":"","Editor$Edit$Advanced$tbEnryPassword":"","Editor$Edit$lkbDraft":"存为草稿"
}

requests自动写博客

1.重新编写草稿内容，然后通过session进行重新发帖（草稿内容部分进行了改变，方便区分）

# coding:utf-8
import requests
import urllib3
from bs4 import BeautifulSoup
urllib3.disable_warnings()
s = requests.session()
s.verify = False  # 全局的
url = 'https://passport.cnblogs.com/user/signin'headers = {"User-Agent":"Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/69.0.3497.81 Safari/537.36"
}
r = s.get(url,headers=headers)
cooks = {".Cnblogs.AspNetCore.Cookies":"XXXXXXXXX",".CNBlogsCookie":"XXXXXX"
}
c = requests.cookies.RequestsCookieJar()
c.set(".CNBlogsCookie", cooks[".CNBlogsCookie"])  # 登陆有效的cookies
c.set(".Cnblogs.AspNetCore.Cookies", cooks[".Cnblogs.AspNetCore.Cookies"])
s.cookies.update(c)
url1 = "https://i.cnblogs.com/EditPosts.aspx?opt=1"
r1 = s.get(url1)
if "博客后台管理" in r1.text:print("登录成功！")
body = {"__VIEWSTATE":"","__VIEWSTATEGENERATOR":"FE27D343","Editor$Edit$txbTitle":"编辑草稿自动写博客","Editor$Edit$EditorBody":"这是编辑草稿的内容自动写博客","Editor$Edit$Advanced$ckbPublished":"on","Editor$Edit$Advanced$chkDisplayHomePage":"on","Editor$Edit$Advanced$chkComments":"on","Editor$Edit$Advanced$chkMainSyndication":"on","Editor$Edit$Advanced$txbEntryName":"","Editor$Edit$Advanced$txbExcerpt":"","Editor$Edit$Advanced$txbTag":"","Editor$Edit$Advanced$tbEnryPassword":"","Editor$Edit$lkbDraft":"存为草稿"
}
# 请求保存草稿接口
r2 = s.post(url1,headers=headers,data=body)

2.发送请求后通过查看博客园的草稿箱查看是否保存成功
