如何向使用POST方法的公共网站发送请求以及如何查找请求的参数，如源和目的地等

Question

I want to collect data of trains for the given 'source and destination' pairs from an public website. I don't want to do this manually, but from the code and automate it. I know it uses POST method. But how do i send my input to the page? i don't know post parameters it uses! Is it possible anyway how to find this.. solutions are much appreciated.

Answer 1

最好的解决方案是使用他们的API，如果他们提供它，否则我将carfull未经他们的许可从网站获取信息。

Answer 2

Use the site like you normally would with the network tab in your browser's dev tools open. When the site makes the request, you can inspect the headers and body of the request. If they didn't release an api they probably don't want you doing this though.

Answer 3

You might want to try to incorporate post-receive programming similar to that used for Github webhooks for your program. Take a look here: https://github.com/aegypius/github-webhook-php
