无聊用python写了个爬虫,来爬我喜欢的图片

Posted 2021-03-03 凌晨five点

还未解决网页超时问题，先放着，爬到一半就没了。

首先看见自己喜欢的图片，忍不住要想下载，一个一个下又很麻烦，只好请求爬虫大大帮助啦。

网页分析：

首先；每一页都对应着，很多的图片

所以我们得先找到没一页对应得url，右键检查

发现对应得页数是以一个单位递增，所以我们已经找到所以页数得url

然后我们要提取，对应页图片下得url。

就会找到对应结点下得图片url，然后进入图片url

同样右键检查。

然后就可以发现对应图片得地址

然后就可以直接写代码了

运行结果

方便多了
