get_request()

SKRequest::PendingRequest * sensesp::SKRequest::get_request ( String  request_id )

staticprotected

Returns the pending request object associated with request_id, or nullptr if no such id is found.

Definition at line 50 of file signalk_put_request.cpp.

Here is the caller graph for this function:

handle_response()

void sensesp::SKRequest::handle_response ( DynamicJsonDocument &  response )

send_request()

String sensesp::SKRequest::send_request ( DynamicJsonDocument &  request, std::function< void(DynamicJsonDocument &)>  callback, uint32_t  timeout = 5000  )

static

Sends the specified request to the server via the connected websocket.

Parameters

request	The json document to send for the request. This document should follow the formats specified in the SignalK Request/Response specification with the exception that it should not contain a "requestId" (as this method will add it).
callback	The callback method that processes any and all responses from the server that correspond to the request.
timeout	The number of milliseconds to wait for a COMPLETED or FAILED response to be received from the server

Returns

The request Id that is sent to the server.
