python爬虫天猫评论

以下是一个示例的Python爬虫代码，用于爬取天猫商品的评论数据：

import requests
from bs4 import BeautifulSoup

def get_tmall_comments(url):
    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'
    }
    response = requests.get(url, headers=headers)
    soup = BeautifulSoup(response.text, 'html.parser')
    
    comments = []
    comment_items = soup.find_all('div', class_='comment-item')
    for item in comment_items:
        username = item.find('div', class_='user-name').text.strip()
        time = item.find('div', class_='date').text.strip()
        product_info = item.find('p', class_='product-info').text.strip()
        content = item.find('div', class_='comment-content').text.strip()
        
        comment = {
            'username': username,
            'time': time,
            'product_info': product_info,
            'content': content
        }
        comments.append(comment)
    
    return comments

# 示例使用
url = 'https://rate.tmall.com/list_detail_rate.htm?itemId=1234567890&page=1'
comments = get_tmall_comments(url)
for comment in comments:
    print(comment)

请注意，这只是一个示例代码，具体的爬取逻辑和网页结构可能会有所不同。你需要根据实际情况进行调整和修改。
