Python 下载首页图片

以下是一个使用RoboBrowser和Python下载首页图片的下载器程序，并使用https://www.duoip.cn/get\_proxy获取代理：

import os
import time
from robobrowser import RoboBrowser
import requests

def get_proxy():
    url = "https://www.duoip.cn/get_proxy"
    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)
    if response.status_code == 200:
        return response.text
    else:
        return None

def download_image(proxy):
    browser = RoboBrowser(history=True, 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")
    proxy_dict = {"http": proxy, "https": proxy}
    browser.set_proxies(proxy_dict)

    url = "https://www.jd.com"
    browser.open(url)
    time.sleep(5)

    # 获取首页图片的URL
    img_url = browser.find_all('img', {'class': 'lazy-image'})[0].get('data-original')

    # 下载图片
    response = requests.get(img_url, stream=True)
    if response.status_code == 200:
        image_content = response.content
        image_filename = os.path.join(os.getcwd(), "jd_image.jpg")
        with open(image_filename, "wb") as image_file:
            image_file.write(image_content)
        print("图片下载完成，保存在：", image_filename)
    else:
        print("图片下载失败")

if __name__ == "__main__":
    proxy = get_proxy()
    if proxy:
        download_image(proxy)
    else:
        print("无法获取代理")

这个程序首先获取一个代理，然后使用RoboBrowser打开jd.com的首页，获取首页图片的URL，并将其下载到本地。请注意，这个程序需要在Python3.6及更高版本下运行。
