## 以上cookies_dict 使用手工方式处理太繁琐,使用split拆分Cookie为字典
## 方法一:
cookies_dict={}
cookies_list = cookies.split("; ")
for cookies in cookies_list:
cookies_dict[cookies.split("=")[0]]=cookies.split("=")[1]
## 方法二:列表推导式
cookies_dict={
cookies.split("=")[0]:cookies.split("=")[1] for cookies in cookies.split("; ")
}
response = requests.get(url,headers=headers,cookies=cookies_dict)
data = response.content
with open("11.4_cookies_dict.html","wb") as f:
f.write(data)
import requests
## 11.5-requests_cookies_auto_login
## 代码实现模拟登录,带着cookie访问
## session 类,可以自动保存cookies,类似于urllib.request中使用的cookieJar
session = requests.session()
# 1.代码登录
login_url = "https://www.yaozh.com/login"
member_url = "https://www.yaozh.com/member/"
headers = {
‘User-Agent‘: ‘Mozilla/5.0 (Windows NT 6.1, Win64, x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/84.0.4147.89 Safari/537.36‘
}
login_form_data = {
‘username‘: ‘moox2020‘,
‘pwd‘: ‘‘,
‘formhash‘: ‘E350124FCF‘, ## formhash和backurl在登录前的页面代码中找
‘backurl‘: ‘%2F%2Fwww.yaozh.com%2F‘, ##
}
## 注意:登录成功之后,cookie保存在response中,但此处的实现,使用session,因此不直接使用requests.post
# url_response = requests.post(login_url,data=login_form_data)
## 登录成功后,session就保存了有效的cookie,再使用session去请求即可
login_response = session.post(login_url,headers=headers,data=login_form_data)
print(login_response.content.decode()) ## 登录成功时:json中包含"state":"success"
## json内容可以使用网站查看:http://www.bejson.com/
# 2.登录成功之后,带着有效的cookies 访问请求目标数据,使用session请求
data = session.get(member_url,headers=headers).content
with open("11.5_cookies_auto_login.html","wb") as f:
f.write(data)
