将数据保存在mongodb中

  • 通过vagrant 安装虚拟机
vagrant up
  • 进入虚拟机

ip 192.168.66.100

su -
#密码:vagrant
docker

  • 拉取mongodb的镜像
docker pull bitnami/mongodb:latest

  • 创建mongodb的容器
mkdir bitnami
cd bitnami
mkdir mongodb
docker run -d -v /path/to/mongodb-persistence:/root/bitnami -p 27017:27017 bitnami/mongodb:latest

通过使用代理ip隐藏爬虫

当app运维人员,发现我们的一直在请求他们的服务器,很可能就把咱们的ip给封了,通过代理ip的方式。隐藏自我。

PS:本次是app数据抓取的入门。首先是通过模拟器的代理服务,到本地的电脑(安装fiddler),这样fiddler就可以抓取数据了,分析数据这块要凭借自己的经验找到对应的url,如果能分析到url,基本爬虫就写一半。封装请求头。通过fiddler获取的。里面header内容比较多,尝试删除最简化,也是一种反爬虫的策略,有的数据放进去到容易被发现是爬虫了,例如cookies等等,但是有的爬虫爬取数据需要cookies。通过代理的方式设置代理ip,防止爬取过程中同一个ip,一直请求一个接口被发现是爬虫。引入了队列的目的就是为了使用线程池的时候方便提取。然后放入mongodb中。这样使用多线程的app数据就完成了。
