php - 获取内网服务器数据

Question

公司要上一套 ERP 系统，会部署在我门自己机房的服务器上，但是我门也想从这个服务器上拿取一些例如订单数据，是要求对方提供数据接口，还是着么样一种方式，把内网的数据通过互联网来抓取，哪种方式对接比较好呢。

问法与思路也许都不对，有经验的多指教一下。

Answer 1

Providing interfaces is the best strategy, reading the database is the middle strategy, and crawling is the worst strategy

Answer 2

Do not connect the intranet server to the Internet, use an intermediary machine

Answer 3

1. If you ask for an interface, it will probably cost more.
2. Is the database also deployed in my own computer room? Then read directly from the database.
3. Capturing is not impossible, but it is unrealistic.

Answer 4

If the order does not require real-time, you can consider using sftp to transmit data. Wouldn’t it be easier to implement?
