CC3200: How to do HTTP POST with JSON data to the HTTP server example code from a WebClient or POSTMAN app?

VIRENDRA KUMAR

Part Number: CC3200

Hi, 

Does the HTTP serve example code in CC3200 SDK support receiving data in JSON format?

If YES, please help me by providing a working example of HTTP POST with JSON format to the CC3200 server example.

Thanks

Virenda

    Hi Virenda,

    The CC3200 SDK contains the JSMN json parser. It is mainly used by http_client (see http_client example).
    On the server side, the CC3200 used the concept of tokens for getting (GET) or setting (PUT) dynamic content.
    It was not designed for that but a token value can contain a json string. In such case, the JSMN lib may be used for parsing it.

    Thanks Kobi, For prompt reply.

    So it means, The CC3200 server example wil only accept data of the "Content-Type:application/x-www-form-urlencoded" ?

    Is there a limit in the size of the Key value of an form , 

    Example : Key : __SL_P_ULD , Value : LED1_OFF

    However if I edit the key to only "__SL" , I do not receive the httpSeverCallback interrupts.

    Thanks
