python3煎蛋网的爬虫

Posted 2020-09-09

做的第一个爬虫就遇上了硬茬儿，可能是我http头没改好还是我点击次数过高导致无法循环爬取煎蛋网的妹子图。。。。

不过也算是邪恶了一把。。。技术本无罪~~~

爬了几页的照片下来还是很赏心悦目的~

    url = ‘http://jandan.net/ooxx/page-2406‘#+str(i)
    read_url(url,k)
    k+=1
    # time.sleep(3)

基本的结构框架也就是：请求网页源代码-->通过正则表达式匹配相应的图片地址返回一个列表-->将列表中所有地址中的内容全部写入一个文件夹。。

 

代码很乱，第一个爬虫权当留个纪念~~~
