Re: [lwip-users] REST API on microcontroller with lwIP

[Marco Giammarini]

You mean genfiles_example/genfiles_example.c? But, how can I use this code with CGI reply?

Hello, 

there is example already provided on how to create a file at runtime. It works well, I have httpd basically generating all my html on the fly.

Dear all,

I am using lwIP over K64 (NXP microcontroller) 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 callback function tCGIHandler is the address of the file).

Does someone implemented REST API with LwIP?

Does someone return a JSON build at runtime?

Does someone parse a GET REST request build with / and not with &? How?  I mean api/test/1/3 instead of api/test.cgi?arg=1&subarg=3

 

Thanks

Marco
