获取商品类别通常需要通过调用某个商品分类接口或者爬取某个电商网站的商品分类信息。以下是两种获取商品类别的示例代码:
1. 调用商品分类接口示例代码(以京东商品分类接口为例):
```python
import requests
# 调用京东商品分类接口,获取商品类别
def get_category(product_name):
url = 'https://dc.3.cn/category/get?callback=getCategoryCallback&'
params = {
'cids': '',
'callback': 'getCategoryCallback',
'ch': '1',
'type': 'search',
'key': product_name
}
response = requests.get(url, params=params)
# 解析接口返回的JSON数据,获取商品类别
category = response.json()['data']['search'][0]['catename']
return category
# 测试代码
product_name = 'iPhone 12'
category = get_category(product_name)
print(f'{product_name}的类别是{category}')
```
2. 爬取电商网站商品分类信息示例代码(以京东电商网站为例):
```python
import requests
from bs4 import BeautifulSoup
# 爬取京东电商网站的商品分类信息,返回一个字典,key为商品名称,value为商品类别
def get_category():
url = 'https://www.jd.com/allSort.aspx'
response = requests.get(url)
soup = BeautifulSoup(response.text, 'html.parser')
category_dict = {}
for li in soup.find_all('li', class_='clearfix'):
category_name = li.find('span', class_='items').get_text().strip()
for a in li.find_all('a'):
product_name = a.get_text().strip()
category_dict[product_name] = category_name
return category_dict
# 获取商品类别
def get_category_by_product_name(product_name, category_dict):
return category_dict.get(product_name)
# 测试代码
product_name = 'iPhone 12'
category_dict = get_category()
category = get_category_by_product_name(product_name, category_dict)
print(f'{product_name}的类别是{category}')
```
