swoole之 swoole_process 应用于TP框架

swoole_process 实现了多进程的管理,多个进程同时进行采集任务,

公司的框架比较low,用的tp框架,结合tp框架实现多进程的采集

这是swoole好的学习资源

     /**
      * 用swoole多进程方法进行采集
      * 采集网贷天眼下各个平台的数据,由于网贷天眼的平台的每个参数指标对应一个ajax请求,
      * 所有设计每个参数指标对应一张表,这样看起来虽然比较繁琐,但有助于数据的更新和维护.
      * 先循环遍历出url表中所有的属于网贷天眼的url,和cid,调用各个抓取参数方法,进行
      * 入库操作
