一个通过搜索关键词，下载谷歌的搜索结果图片的爬虫。比如：配置了关键词“猫”，“狗”，运行代码，就会把Google搜索中“猫”、“狗”的图片分别以目录的方式保存。代码运行中会弹出Chome浏览器，这是在模拟浏览器访问，不用管就行了。
开源：https://github.com/ohyicong/Google-Image-Scraper
安装使用很简单，配置好python环境后，安装分三步：
git clone https://github.com/ohyicong/Google-Image-Scraper
pip install selenium, requests, pillow
python main.py
样例代码，也就是main.py的代码也很简单：
#Import libraries (Don't change)
from GoogleImageScrapper import GoogleImageScraper
import os
from patch import webdriver_executable
#Define file path (Don't change)
webdriver_path = os.path.normpath(os.path.join(os.getcwd(), 'webdriver', webdriver_executable()))
image_path = os.path.normpath(os.path.join(os.getcwd(), 'photos'))
#Add new search key into array ["cat","t-shirt","apple","orange","pear","fish"]
search_keys= ["cat","t-shirt"]
#Parameters
number_of_images = 10
headless = True
min_resolution=(0,0)
max_resolution=(1920,1080)
#Main program
for search_key in search_keys:
image_scrapper = GoogleImageScraper(webdriver_path,image_path,search_key,number_of_images,headless,min_resolution,max_resolution)
image_urls = image_scrapper.find_image_urls()
image_scrapper.save_images(image_urls)
