I am using lwIP over K64 and I would add REST API to my project.
I try to understand how to do that, and the only way that I have found is to use CGI. The problem is the reply: I can reply only with a static file present in the SDCARD (the return of the following function is the address of the file.
typedef const char *(*tCGIHandler)(int iIndex, int iNumParams, char *pcParam,char *pcValue);
Does someone return a JSON build at runtime?
Does someone parse a GET REST request build with / and not with &? How?
api/test/1/3 indeed of api/test.cgi?arg=1&subarg=3
