How to send POST from phone?

Question

React Native

I start the local server localhost:5555, then I start expo and from the physical phone through Expo Go I launch the application in which a post request should be sent to the local server localhost:5555. But something doesn't work :)

Answer 1

localhost does not work on the local network, but only on one computer, you can use it with the emulator. If you want to test from a physical phone, you need to contact by ip

When I throw on IP 198.168.8.100 -> 404, but I'm sure that everything is correct, I just throw it in the wrong place.
when on localhost then network error

Try specifying a port here.
Plus a small addition, not all programs work with localhost, some need 127.0.0.1
