写在前面

工作中遇到，简单整理
理解不足小伙伴帮忙指正

对每个人而言，真正的职责只有一个：找到自我。然后在心中坚守其一生，全心全意，永不停息。所有其它的路都是不完整的，是人的逃避方式，是对大众理想的懦弱回归，是随波逐流，是对内心的恐惧 ——赫尔曼·黑塞《德米安》

采集流程：

自动登陆
获取商家排名页当前页数据
获取总页数，和下一页对应元素
根据总页数循环遍历，模拟点击下一页获取数据分页数据
数据汇总

from seleniumwire import webdriver

from selenium.webdriver.common.by import By

df.to_csv('CDN_Manufacturer.csv', index=False)print("数据已保存为CSV文件")

pd 直接打印生成结果

数据可视化

通过 pyecharts 对数据做简单可视化

def to_echarts(CDN_Manufacturer):from pyecharts.charts import Barfrom pyecharts import options as opts# 内置主题类型可查看 pyecharts.globals.ThemeTypefrom pyecharts.globals import ThemeTypexaxis =  [ cdn["公司名称"] for cdn in   CDN_Manufacturer ][:10]yaxis1 =  [ cdn["CDN网站数量"] for cdn in   CDN_Manufacturer ][:10]yaxis2 =  [ cdn["IP节点"] for cdn in   CDN_Manufacturer ][:10]bar = (Bar(init_opts=opts.InitOpts(theme=ThemeType.LIGHT)).add_xaxis(xaxis).add_yaxis("CDN网站数量", yaxis1).add_yaxis("IP节点", yaxis2).set_global_opts(title_opts=opts.TitleOpts(title="主标题", subtitle="副标题"))
)  bar.render()
