python爬虫爬取图片

以下是Python爬虫爬取图片的基本步骤：

1. 导入必要的模块

import requests
from bs4 import BeautifulSoup
import os

2. 获取网页源代码

url = 'https://www.example.com' # 要爬取图片的网址
response = requests.get(url)
html = response.text

3. 解析HTML代码

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

4. 查找图片链接

img_tags = soup.find_all('img')
img_urls = [img['src'] for img in img_tags]

5. 下载图片

for url in img_urls:
    response = requests.get(url)
    filename = os.path.basename(url) # 获取文件名
    with open(filename, 'wb') as f:
        f.write(response.content)

完整的Python爬虫爬取图片的代码如下：

import requests
from bs4 import BeautifulSoup
import os

url = 'https://www.example.com'
response = requests.get(url)
html = response.text

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

img_tags = soup.find_all('img')
img_urls = [img['src'] for img in img_tags]

for url in img_urls:
    response = requests.get(url)
    filename = os.path.basename(url)
    with open(filename, 'wb') as f:
        f.write(response.content)
