Re: Help needed with uploading data to HTTP Server

Thanks Mark,

But how under which http_getAction(state) action is data parse?  Is it CGI_DATA? Also do I respond to client under this same action? Example of http post data is:
{
    "sensor 2": 1,
    "name": "contact sensor",
    "username": "sandy",
    "password": "access",
    "msg": [{"update"}]
}

But at the end return something else (1, CGI_DONE, CGI_SEND_DONE...). Or else you client will wait until a socket time-out will occurs.
