京东商城三页数据抓取python

您可以使用Python中的requests和BeautifulSoup库来实现京东商城三页数据的抓取。具体步骤如下：

1. 导入requests和BeautifulSoup库

import requests
from bs4 import BeautifulSoup

2. 构造请求头和请求参数

headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3'}
params = {
    'keyword': '手机',
    'enc': 'utf-8',
    'page': 1
}

3. 发送请求并解析响应

url = 'https://search.jd.com/Search'
response = requests.get(url, headers=headers, params=params)
soup = BeautifulSoup(response.text, 'html.parser')

4. 提取数据

items = soup.select('#J_goodsList .gl-item')
for item in items:
    name = item.select('.p-name em')[0].text.strip()
    price = item.select('.p-price i')[0].text.strip()
    print(name, price)

5. 循环抓取多页数据

for page in range(1, 4):
    params['page'] = page
    response = requests.get(url, headers=headers, params=params)
    soup = BeautifulSoup(response.text, 'html.parser')
    items = soup.select('#J_goodsList .gl-item')
    for item in items:
        name = item.select('.p-name em')[0].text.strip()
        price = item.select('.p-price i')[0].text.strip()
        print(name, price)
