解决思路
1,利用post向wordpress提交表单
2,通过wordpress_xmlrpc模块,有轮子不用想干啥
3,通过mysqldb直接插入数据库,有服务器、不需远程,直接把py脚本放在服务器跑
我们这次要用轮子拼一台摩托车!,宝马、、自己动手吧
开始动手:需自行安装的模块requests,xmlrpc;windows系统、linux安装如下,土豪随意:
pip install requests
pip install python-wordpress-xmlrpc
caiji.py

设置采集内容到哪个默认目录,可以在wp后台设置,从代码上做修改也可以;具体可以看看xmlrpc官方文档:http://python-wordpress-xmlrpc.readthedocs.io/en/latest/overview.html
另外可以通过命令crontab -e 让脚本按需自动跑起来!
