使用方法：

百度图片爬虫，基于python3

需要安装python版本 >= 3.6

使用方法

$ python crawling.py -husage: crawling.py [-h] -w WORD -tp TOTAL_PAGE -sp START_PAGE                   [-pp [{10,20,30,40,50,60,70,80,90,100}]] [-d DELAY]optional arguments:  -h, --help            show this help message and exit  -w WORD, --word WORD  抓取关键词  -tp TOTAL_PAGE, --total_page TOTAL_PAGE                        需要抓取的总页数  -sp START_PAGE, --start_page START_PAGE                        起始页数  -pp [{10,20,30,40,50,60,70,80,90,100}], --per_page [{10,20,30,40,50,60,70,80,90,100}]                        每页大小  -d DELAY, --delay DELAY                        抓取延时（间隔）

开始爬取图片

python crawling.py --word "丁真" --total_page 10 --start_page 1 --per_page 30

另外也可以在crawling.py最后一行修改编辑查找关键字
图片默认保存在项目路径
运行爬虫：

python crawling.py
