python - 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

使用google-images-download时如何从google下载图片并同时用关键字重命名图片？使用此包时，名称是从图像 URL 生成的

我所不同的是图像可以用项目名称命名 有人可以帮助我吗？

这里是代码:

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)

您需要重写 google_images_download 中的方法，包括:download_image、_get_all_items、download。 _get_all_items并下载需要发布download_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 socket_timeout:

                else:
                    timeout = 10

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