python编写简单的爬取图片程序

话不多说直接上代码

import requests
from bs4 import BeautifulSoup
import os

def download_image(url, save_directory):
    # 发送GET请求
    response = requests.get(url)
    # 获取图片文件名
    file_name = url.split("/")[-1]
    # 拼接保存路径
    save_path = os.path.join(save_directory, file_name)
    # 保存图片到本地
    with open(save_path, "wb") as file:
        file.write(response.content)
    print(f"图片 {file_name} 下载成功！")

def crawl_images(url, save_directory):
    # 发送GET请求
    response = requests.get(url)
    # 使用BeautifulSoup解析HTML内容
    soup = BeautifulSoup(response.text, "html.parser")
    # 查找所有的标签
    img_tags = soup.find_all("img")
    # 遍历每个标签，获取图片URL并下载保存
    for img_tag in img_tags:
        try:
            image_url = img_tag["src"]
            download_image(image_url, save_directory)
        except Exception as e:
            print(f"图片下载失败: {e}")

# 设置要爬取的网页URL和保存图片的目录
url = "https://www.example.com"
save_directory = "images"

# 创建保存目录
os.makedirs(save_directory, exist_ok=True)

# 开始爬取图片
crawl_images(url, save_directory)
 

记得更改爬取的网址和保存目录

开头的两个库也要用pip获取
