Debug tool request

[ScottR]

Forgive me if this question is a basic one, but can you please suggest how to get more information displayed in the UART messages about the POST and GET requests?

The IoT_Demo code currently prints "We have a POST request.", or "We have a GET request". It would be very useful for debugging if it would also print the parsed JSON data to help make sure the JSON commands in the POST / GET are being received and interpreted properly.

Scott.

hi Scott

I ran into the same problem, but solved it by adding some printstatement, where the JSON is parsed

Like in this statement

LOCAL struct jsontree_callback status_callback = JSONTREE_CALLBACK(status_get, status_set);

Where the first parameter is used when GETting your values and setting it into the JSON-variable, and the second is SETting your variables from values in the JSON-variable.

ANd then in the status-set function adding

/******************************************************************************
* FunctionName : status_set
* Description : parse the device status parmer as a JSON format
* Parameters : js_ctx -- A pointer to a JSON set up
* parser -- A pointer to a JSON parser state
* Returns : result
*******************************************************************************/
LOCAL int ICACHE_FLASH_ATTR
status_set(struct jsontree_context *js_ctx, struct jsonparse_state *parser)
{
int type;

while ((type = jsonparse_next(parser)) != 0) {
if (type == JSON_TYPE_PAIR_NAME) {
if (jsonparse_strcmp_value(parser, "status") == 0) {
uint8 status;
jsonparse_next(parser);
jsonparse_next(parser);
status = jsonparse_get_value_as_int(parser);
user_plug_set_status(status);
os_printf("status: %d\n", status);
}
}
}

return 0;
}
