爬虫案例：彼岸图网4K图片数据爬取

以下是一个简化的版本，用于演示如何使用Python爬取彼岸图网上的4K高清图片。

import requests
from bs4 import BeautifulSoup
import os
 
def download_image(url, filename):
    response = requests.get(url)
    with open(filename, 'wb') as file:
        file.write(response.content)
 
def crawl_behance_images(username, max_pages=2):
    base_url = f'https://www.behance.net/{username}'
    os.makedirs(username, exist_ok=True)
    page_number = 1
    while page_number <= max_pages:
        print(f'Crawling page {page_number}')
        url = f'{base_url}/gallery/{{project_id}}/revisions?page={page_number}&display_type=grid&sort=recent'
        response = requests.get(url)
        soup = BeautifulSoup(response.text, 'html.parser')
        image_urls = [image['src'] for image in soup.find_all('img', class_='image') if image['src'].endswith('.jpg')]
        for image_url in image_urls:
            filename = os.path.basename(image_url)
            download_image(image_url, os.path.join(username, filename))
        page_number += 1
 
crawl_behance_images('username_example', max_pages=1)  # 替换为具体的用户名
