前言

正文

目标网站divinl

看起来还挺清晰的,单击新窗口打开图片,还可以

大图

然后下载图片,说实话,这图片很小,我很担心不是高清原图(管他的);


比较小

PS:一定要禁用广告拦截插件,不然加载不出图,我就在这被坑T_T;

禁用过滤广告插件
接着分析我们从何入手

1、先去主页面获取每个图片的详细页面的链接
这链接还是比较好获取的,直接 F12 审核元素,或者右键查看代码,手机上chrome和firefox在url前面加上 "view-source",比如: view-source:https://www.baidu.com/

链接
2、从详细页面获取图片大图地址
随便打开一个图片详细页面如图:
详细页面
接着按 F12 审核元素,我们需要定位该图片的链接,首先单击左上角的这玩意儿,像一个鼠标的图标:
左上角,一个鼠标的图标
接着只需要单击网页上的图片就能定位到代码了:
代码

3、用大图地址下载该图片
这个很简单,看代码

代码(纯手打,没有一点复制粘贴)
