前言

使用Selenium进行自动渲染获取数据

提示：以下是本篇文章正文内容，下面案例可供参考

思路

以机油为例:

首先进入机油的界面

可以发现有很多品牌



按F12 去找到所有分类的父标签

可以发现每一个分类就是一个Li标签,我们可以通过这些标签进入每一个品牌中,跳转到每一品牌的商品列表上

然后获取每一个商品的详情链接,价格,品牌的名称,商品的图片,商品的标题名称

重点就是进行翻页的动作


有两种方式:

  1. 去发现每一页地址链接的规律
  2. 使用自动点击的方式进行获取下一页

在下面的代码中我个人使用的是第一种方式
我之前的文章有第二种方式的使用
Selenium:测试抓取京东数据练习[汽车用品-机油]

最后注意一点就是每进入新的一页它是会显示一半数据
                                                    另一半数据需要手动的下拉滑动

下拉滑动的动作有点丑陋大家见笑了:

'''
:@browser  是Selenium 的实例对象
'''
def windows(browser):for i in range(0, 10000, 50):windowBout(browser, i)for i in range(10000, 0, -50):windowTop(browser, i)for i in range(0, 10000, 50):windowBout(browser, i)
def windowBout(browser,i):js = f"window.scrollTo(0,{i})"browser.execute_script(js)def windowTop(browser, i):js = f"window.scrollTo(0,{i})"browser.execute_script(js)

在这里我只获取了每个商品详情的连接,并没有在进行下一步获取,在之前Selenium:测试抓取京东数据练习[汽车用品-机油]这个文章中就获取所有的详情页面的数据在进行返回,不过效率太慢,所有我只获取了

接下来上代码
