登陆的方式
1.实例化session,使用session发送post请求,在使用它获取登陆后的页面

# coding=utf-8
import requests

session = requests.session()
post_url = "http://www.renren.com/PLogin.do"
post_data = {"email":"mr_mao_hacker@163.com", "password":"alarmchime"}
headers = {
    "User-Agent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.84 Safari/537.36"
}
#使用session发送post请求,cookie保存在其中
session.post(post_url,data=post_data,headers=headers)

#在使用session进行请求登陆之后才能访问的地址
r = session.get("http://www.renren.com/327550029/profile",headers=headers)

#保存页面
with open("renren1.html","w",encoding="utf-8") as f:
    f.write(r.content.decode())

2.headers中添加cookie键,值为cookie字符串

# coding=utf-8
import requests

headers = {
    "User-Agent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.84 Safari/537.36",
    "Cookie":"anonymid=j3jxk555-nrn0wh; _r01_=1; _ga=GA1.2.1274811859.1497951251; _de=BF09EE3A28DED52E6B65F6A4705D973F1383380866D39FF5; ln_uact=mr_mao_hacker@163.com; depovince=BJ; jebecookies=54f5d0fd-9299-4bb4-801c-eefa4fd3012b|||||; JSESSIONID=abcI6TfWH4N4t_aWJnvdw; ick_login=4be198ce-1f9c-4eab-971d-48abfda70a50; p=0cbee3304bce1ede82a56e901916d0949; first_login_flag=1; ln_hurl=http://hdn.xnimg.cn/photos/hdn421/20171230/1635/main_JQzq_ae7b0000a8791986.jpg; t=79bdd322e760beae79c0b511b8c92a6b9; societyguester=79bdd322e760beae79c0b511b8c92a6b9; id=327550029; xnsid=2ac9a5d8; loginfrom=syshome; ch_id=10016; wp_fold=0"
}

r = requests.get("http://www.renren.com/327550029/profile",headers=headers)

#保存页面
with open("renren2.html","w",encoding="utf-8") as f:
    f.write(r.content.decode())

3.在请求方法中添加cookies参数,接收字典形式的cookie.字典形式的cookie中的键是cookie的name,值是cookie的value

# coding=utf-8
import requests

headers = {
   "User-Agent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.84 Safari/537.36",
}

cookies="anonymid=j3jxk555-nrn0wh; _r01_=1; _ga=GA1.2.1274811859.1497951251; _de=BF09EE3A28DED52E6B65F6A4705D973F1383380866D39FF5; ln_uact=mr_mao_hacker@163.com; depovince=BJ; jebecookies=54f5d0fd-9299-4bb4-801c-eefa4fd3012b|||||; JSESSIONID=abcI6TfWH4N4t_aWJnvdw; ick_login=4be198ce-1f9c-4eab-971d-48abfda70a50; p=0cbee3304bce1ede82a56e901916d0949; first_login_flag=1; ln_hurl=http://hdn.xnimg.cn/photos/hdn421/20171230/1635/main_JQzq_ae7b0000a8791986.jpg; t=79bdd322e760beae79c0b511b8c92a6b9; societyguester=79bdd322e760beae79c0b511b8c92a6b9; id=327550029; xnsid=2ac9a5d8; loginfrom=syshome; ch_id=10016; wp_fold=0"
cookies = {i.split("=")[0]:i.split("=")[1] for i in cookies.split("; ")}
print(cookies) 

r = requests.get("http://www.renren.com/327550029/profile",headers=headers,cookies=cookies)

#保存页面
with open("renren3.html","w",encoding="utf-8") as f:
   f.write(r.content.decode())
