How to implement validation of incoming data on the server sent from android?

Question

PHP

Good afternoon!
The situation is as follows: there is an android application with a form. When submitting the form, the data is sent to the site.
Question: how to check the data on the server? How to generate a token?
Thanks in advance!

Answer 1

What's the problem with the form? Everything is the same as with the form sent from the site. It really depends on the framework you're using.
Session token or CSRF protection?
For the first it seems to me it will be easier to use cookies. For the second, it is easier to send a specific header, which the browser will not send and that's it.
From the point of view of routing, it is ideologically correct to use REST full, but not at all necessary.
