爬取京东电脑图片并保存用BeautifulSoup库

好的，下面是实现步骤：

1.导入需要的库

from bs4 import BeautifulSoup
import requests
import os

2.获取京东电脑页面的HTML内容

url = "https://search.jd.com/Search?keyword=%E7%94%B5%E8%84%91&enc=utf-8&wq=%E7%94%B5%E8%84%91&pvid=fb1d9f6b63eb4b1d8f9d5f9d9d7f0f6c"
response = requests.get(url)
html_content = response.text

3.使用BeautifulSoup解析HTML内容

soup = BeautifulSoup(html_content, 'html.parser')

4.查找所有电脑图片的标签

img_tags = soup.find_all('img', class_='err-product')

5.循环遍历所有图片标签，获取图片路径并保存

for img in img_tags:
    img_url = img['src']
    img_name = img_url.split('/')[-1]
    img_path = os.path.join('电脑图片', img_name)
    img_data = requests.get(img_url).content
    with open(img_path, 'wb') as f:
        f.write(img_data)

完整代码如下：

from bs4 import BeautifulSoup
import requests
import os

url = "https://search.jd.com/Search?keyword=%E7%94%B5%E8%84%91&enc=utf-8&wq=%E7%94%B5%E8%84%91&pvid=fb1d9f6b63eb4b1d8f9d5f9d9d7f0f6c"
response = requests.get(url)
html_content = response.text

soup = BeautifulSoup(html_content, 'html.parser')

img_tags = soup.find_all('img', class_='err-product')

if not os.path.exists('电脑图片'):
    os.mkdir('电脑图片')

for img in img_tags:
    img_url = img['src']
    img_name = img_url.split('/')[-1]
    img_path = os.path.join('电脑图片', img_name)
    img_data = requests.get(img_url).content
    with open(img_path, 'wb') as f:
        f.write(img_data)
