工作需要遇到，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》

逻辑相对简单，主要通过站长之家 https://cdn.chinaz.com/，获取全国省市的 CDN节点 IP 信息

采集流程：

获取CDN 厂家信息

在这里插入图片描述

跳转页面到指定的厂家，择需要获取的省份

在这里插入图片描述

获取当前页IP，循环处理分页数据

在这里插入图片描述

处理完当前省份，循环跳转其他省份处理
处理完当前厂家，循环处理其他厂家
