python爬虫指定关键字抓图片（能直接用的代码）

以下是一个简单的 Python 爬虫代码，可以利用关键字（例如“dog”）从 Google Images 上抓取图片：

import requests
from urllib.parse import urlparse, parse_qs
from bs4 import BeautifulSoup
from io import BytesIO
from PIL import Image

keyword = "dog"
url = f"https://www.google.com/search?q={keyword}&tbm=isch"

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.content, 'html.parser')
images = soup.find_all("img")
for img in images:
    img_url = img.attrs.get("src")
    if not img_url:
        img_url = img.attrs.get("data-src")
    if not img_url:
        continue
    if "http" not in img_url:
        img_url = f"https:{img_url}"
    try:
        image_content = requests.get(img_url).content
    except Exception as e:
        print(f"ERROR - Could not download {img_url} - {e}")
        continue
    try:
        image_file = BytesIO(image_content)
        image = Image.open(image_file).convert('RGB')
        file_name = urlparse(img_url).path.split("/")[-1]
        with open(file_name, "wb") as f:
            image.save(f, "JPEG", quality=85)
    except Exception as e:
        print(f"ERROR - Could not save {img_url} - {e}")
        continue
