python 爬取图片 壁纸自动切换

1.爬取图片，作为壁纸，用来接下来的壁纸自动切换
python代码里的库如果报错，记得下库
pip install 加库名

代码

import requests
import parsel

# 10,15爬取10到15页的图片
for pag in range(10, 15):
    print(f'=========={pag}页=====')
    # 设置网页
    url = f'http://www.netbian.com/meinv/index_{pag}.htm'
    # 设置浏览器
    headers = {

    #
    responrse = requests.get(url=url, headers=headers)
    # html_data = responrse.content.decode('utf-8')
    responrse.encoding = responrse.apparent_encoding
    # print(responrse.text)
    selctor = parsel.Selector(responrse.text)
    lis = selctor.css('.list li')
    # print(lis)
    for li in lis:
        title = li.css('b::text').get()
        # print(title)
        if title:
            href = 'http://www.netbian.com/' + li.css('a::attr(href)').get()
            # print(href, title)
            response_i = requests.get(url=href, headers=headers)
            seletor_i = parsel.Selector(response_i.text)
            img_url = seletor_i.css('.pic img::attr(src)').get()
            # print(href,title,img_url)
            img_countent = requests.get(url=img_url, headers=headers).content
            # 图片保存在当前img目录下
            with open('img\' + title + '.jpg', mode='wb') as f:
                f.write(img_countent)
                print('正在保存：' + title)

运行代码，图片保存在img目录下

def read_xml():
    doc = parse("./config.xml")
    root = doc.documentElement
    global path,random_time
    path = root.getElementsByTagName("path")[0].firstChild.data
    random_time = int(root.getElementsByTagName("random_time")[0].firstChild.data)

def list_all_pic(pic_dir):
    pic_files = []

    for i in range(0,len(files_list)):

        if os.path.isfile(full_path):
            if full_path.rsplit(".")[-1].lower() in ["jpg","bmp","jpeg","png"]:
                pic_files.append(full_path)
    return pic_files
def random_pic_index():
    return picture_list[random.randint(0,len(picture_list)-1)]

def main():
    read_xml()
    global picture_list
    picture_list = list_all_pic(path)
    if len(picture_list) == 0:
        print("文件夹中没有壁纸")
        exit(1)
    while True:
        file_name = random_pic_index()
        ctypes.windll.user32.SystemParametersInfoW(20,0,file_name,0)
        print("{} 图像名：{}".format(datetime.datetime.strftime(datetime.datetime.now(),"%y-%m-%d %H:%M:%S"),file_name))
        time.sleep(random_time)

if __name__ == '__main__':
    main()




```python

编写.xml文件

    F:/python/pythonFile/wallpaper/img
