爬虫基础——示例：登录抽屉并点赞

   原理

1. 访问抽屉，获取获取cookie (c1)；

2. 登录时候，携带cookie (c1)；

3. 点赞时候，携带cookie (c1)；

每一次发送请求，请求头必须设置 user-agent

   方法一

import requests

### 访问 ###
r1 = requests.get(
    url="https://dig.chouti.com/",
    headers = {
        'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.99 Safari/537.36}'
    },
)
r1_cookie = r1.cookies.get_dict()
print(r1_cookie)

### end ###

### 登录 ###
post_dict = {
    'phone': '86xxxxx',
    'password': 'xxxxxx',
    'oneMonth': 1,
}
r2 = requests.post(
    url="https://dig.chouti.com/login",
    data=post_dict,
    headers= {
        'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.99 Safari/537.36}'
    },
    cookies=r1_cookie,
)

r2_cookie = r2.cookies.get_dict()  # 该cookie没有用到
print(r2_cookie)
### end ##

### 点赞 ###
r3 = requests.post(
    url="https://dig.chouti.com/link/vote?linksId=20476281",
    headers = {
        'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.99 Safari/537.36}'
    },
    cookies=r1_cookie
)

print(r3.text)

### end ###

 

   方法二

import requests


session = requests.Session()


### 访问 ###
r1 = session.get(
    url="https://dig.chouti.com/",
    headers = {
        'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.99 Safari/537.36}'
    },
)


### end ###

### 登录 ###
post_dict = {
    'phone': '86xxxxxx',
    'password': 'xxxx',
    'oneMonth': 1,
}
r2 = session.post(
    url="https://dig.chouti.com/login",
    data=post_dict,
    headers = {
        'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.99 Safari/537.36}'
    },
)

### end ##

### 点赞 ###
r3 = session.post(
    url="https://dig.chouti.com/link/vote?linksId=20487636",
    headers = {
        'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.99 Safari/537.36}'
