如何从 google 下载图片并在 google-images-download 中同时用关键字重命名图片

Question

如何在使用google-images-download的时候从google下载图片并同时用关键词重命名图片？使用此包时，名称是从图像生成的 URL

我除了图片可以用Item名称来命名谁能帮帮我？

代码如下：

from google_images_download import google_images_download

response = google_images_download.googleimagesdownload()
arguments = {"keywords":"cat, dog, pig", "limit":1, "print_urls":True, "image_directory":'home1', "size":"large"} 
absolute_image_paths = response.download(arguments)

您需要覆盖 google_images_download 中的方法，包括：download_image、_get_all_items、下载。 _get_all_items下载需要postdownload_image

# Download Images
    def download_image(self,image_url,image_format,main_directory,dir_name,count,print_urls,socket_timeout,prefix,print_size,no_numbering,search_term):
        if print_urls:
            print("Image URL: " + image_url)
        try:
            req = Request(image_url, headers={

                if socket_timeout:

                else:
                    timeout = 10

                response = urlopen(req, None, timeout)
                data = response.read()
                response.close()
