要爬取手机排行榜的数据,你需要先了解目标网站的结构和网页源代码,然后使用Python中的requests和BeautifulSoup库来爬取和解析数据。
以下是一些基本步骤:
1. 导入requests和BeautifulSoup库:
```python
import requests
from bs4 import BeautifulSoup
```
2. 发送HTTP请求,获取网页源代码:
```python
url = 'https://www.jd.com/allSort.aspx'
response = requests.get(url)
html = response.text
```
3. 使用BeautifulSoup解析网页源代码,查找目标元素:
```python
soup = BeautifulSoup(html, 'html.parser')
rank_list = soup.find('div', {'class': 'm m-2'}).find_all('li')
```
4. 遍历目标元素,获取手机排行榜数据:
```python
for rank in rank_list:
name = rank.find('div', {'class': 'p-name'}).text.strip()
price = rank.find('div', {'class': 'p-price'}).strong.i.text.strip()
print(name, price)
```
完整代码如下:
```python
import requests
from bs4 import BeautifulSoup
url = 'https://www.jd.com/allSort.aspx'
response = requests.get(url)
html = response.text
soup = BeautifulSoup(html, 'html.parser')
rank_list = soup.find('div', {'class': 'm m-2'}).find_all('li')
for rank in rank_list:
name = rank.find('div', {'class': 'p-name'}).text.strip()
price = rank.find('div', {'class': 'p-price'}).strong.i.text.strip()
print(name, price)
```
