how to send integer number from http webserver to stm32 micro controller using httpd

[abeba.1]

hii everyone 

i would like to send an integer number that i get from the user on html webpage to the stm32  controller

lets say in the controller i just want to print the number that received from the webpage 

what is the method that i need to use in order to receive an integer number from a web page 

i saw once a method to send a string called CGI but i need to transfer an integer number  not a char or a string how can i do this

Surely, HTML is inherently text based?

(the clue is in the name - the 'T' stands for "Text")

So everything is just a char or a string.

It's not difficult to convert from a char or string to a number - there are standard library functions for that ...

hii thanks for your help can you give me the name of the library to use and the function to the conversion fro char to integer

Go on - it's in the Standard C Library.

See any C reference or textbook; eg, https://en.cppreference.com/w/c/string/byte

How about web sockets?

Perhaps look at atoi() or sscanf() ?

The conversion is pretty basic stuff, using decimal math.

Perhaps look more broadly at text and string handling and parsing.
