cookies组成结构

 

cookie ={u'domain': u'.cnblogs.com',
             u'name': u'.CNBlogsCookie',
             u'value': u'xxxx',              
             u'expiry': 1554959887,              
             u'path': u'/',              
             u'httpOnly': True,              
             u'secure': False
}
name：cookie的名称
value：cookie对应的值，动态生成的
domain（多米）：服务器域名
expiry（伊克斯百瑞）：Cookie有效终止日期
path：Path属性定义了Web服务器上哪些路径下的页面可获取服务器设置的Cookie
httpOnly：防脚本攻击
secure（c q）:在Cookie中标记该变量，表明只有当浏览器和Web Server之间的通信协议为加密认证协议时，
浏览器才向服务器提交相应的Cookie。当前这种协议只有一种，即为HTTPS。

 

正则提取body内容

import requests
import re
url = "http://47.104.190.48:8000/login/"
r = requests.get(url)
print(r.cookies)    # 返回的cookies
# print(r.text)

# re 正则表达式，知道前面和后面，取中间值，取出来是个list
token = re.findall('name="csrfmiddlewaretoken" value="(.+?)"', r.text)
print(token[0])

body = {
    "csrfmiddlewaretoken": token[0],
    "username": "test111",
    "password": "123456"
}
r2 = requests.post(url, data=body, cookies=r.cookies)
print(r2.text)

# 判断是否登录成功
assert "登录成功！" in r2.text

重定向302

 

import requests

url = "http://47.104.190.48:8000/change/"

r = requests.get(url)   #r就是一个Response对象
print(r.status_code)     # 最后一个状态码
print(r.url)
print(r.headers)

all = r.history  # 是个list，里面放的是Response对象302,history不包括最后一次返回的状

态码
print(all[0].status_code)
print(all[0].headers['Location'])
print(all[0].url)   

# for i in all:
#     print(i)  # Response [302] 对象   从定向302是没有body的

 

 

 取token值

 

import requests
import re
s = requests.session()   # 代码里面的浏览器
print(s.headers)
print(s.cookies)

url = "http://47.104.190.48:8000/register/"
r1 = s.get(url)

print(s.cookies)

token = re.findall('name="csrfmiddlewaretoken" value="(.+?)"', r1.text)
print(token[0])

body = {
    "csrfmiddlewaretoken": token[0],
    "username": "t1223",
    "password": "111",
    "email": "111",
}
r2 = s.post(url, data=body)
print(r2.text)

 

 post

import requests
import re
s = requests.session()   # 代码里面的浏览器

print(s.cookies)

url = "http://47.104.190.48:8000/register/"
r1 = s.get(url)

print(s.cookies)

token = re.findall('name="csrfmiddlewaretoken" value="(.+?)"', r1.text)
print(token[0])

    "csrfmiddlewaretoken": token[0],
    "username": "t1223",

}
r2 = s.post(url, data=body)
print(r2.text)

# 判断是否登录成功
