Web interface for C++ application

[mickes27]

Hello. I have a program written in C++, but at this moment it works in console. I was using SFML for making graphic interface previously, but this time I want to try something new. My program is suppose to work on embedded system (like Raspberry Pi), so I won't have display screen for it. Instead of that, I wanted to make some web browser interface for it. User has to type Raspberry Pi IP in own browser, along with port (for example 192.168.48.5:8888) and than he should see the simple interface (not much, just a few buttons). After clicking button, certain things should happen in C++ program. Am I able to achieve that with SFML? Where should I search? Is it CGI/REST API?

Example: UV4L with it's webRTC server (it has interface I am looking for - https://i.stack.imgur.com/w5Yhz.png?fbclid=IwAR1UexTVjdM8rDe5O8apC6_lULzVMJsT9rL1qDk9mAjyEPqnVOFvBjZ5PyA)

Thanks for help

SFML only provides a HTTP client and TCP Sockets, as such writing your own server with SFML isn't exactly trivial, as you need to implement the whole HTTP protocol your self using a TCP socket.
Alternatively, you may find some (header-only) libraries that handle HTTP parsing for you.

You can start off by reading the networking tutorial, API documentation and FAQ.

So you think it should be better to use some other library?

You can try chrome cef
https://en.wikipedia.org/wiki/Chromium_Embedded_Framework

you can register javascript functions and talk via your c++ code

do not forget to built cef without sandbox security

That's a bit drastic to jump from a simple HTTP server to full-blown browser engine, also a bit apples and oranges.

SFML certainly isn't the best tool if your goal is to create a server. It can be done, but it will require a lot of work or use of third-party libraries.

For example, Wt does what you want.
