Hi,

I'm using a SPWF04Sx WIFI module.

In AT.HTTPOST command there isn't a field for a JSON payload, but I really need it.

There is something that allow me to send a JSON payload ?

There isn't also a field for the call's header that i've to fill with a token. There is someone that can solve my problems?

Thanks in advance!

#json #spwf04sx #http-post

    Hi,

    you have to save the JSON payload in a file with .json extension and specify that file name as last parameter of AT+S.HTTPPOST command.

    Hi Elio,

    Can you make me an example of a .json file?

    it is like : 

    {

       'identifier':'centralina',

       'password':'password'

    }

    ?

    And the json file has to be saved in the WIFI module ? if it's so can you explain me how ?

    Hi,

    it's a regular text file containing JSON formatted data and named with .json extension.

    With your example you can type the following sequence into the serial console and get the data saved into example.json:

    AT+S.FSC=example.json,61<CR>{<CR><LF>   'identifier':'centralina',<CR><LF>'password':'password'<CR><LF>}

    AT-S.OK

    Now you can send your JSON object by AT+S.HTTPPOST. The following command send your post request to httpbin server to get it analyzed:

    AT+S.HTTPPOST=httpbin.org,/post,,,,,,example.json<CR>

    AT-S.Http Server Status Code:200

    {

       'args':{

       },

       'data':'{\r\n   \'identifier\':\'centralina\',\r\n   \'password\':\'password\'\r\n}',

       'files':{

       },

       'form':{

       },

       'headers':{

          'Connection':'close',

          'Content-Type':'application/json',

          'Host':'httpbin.org',

          'Transfer-Encoding':'chunked',

          'User-Agent':'HTTP-Client'

       },

       'json':{

          'identifier':'centralina',

          'password':'password'

       },

       'origin':'62.110.21.125',

       'url':'

    http://httpbin.org/post

    '

    }
