Function: jsonRPCRequestOfContext()

jsonRPCRequestOfContext(context): JSONRPCRequestInfo | undefined

Get the JSON-RPC request behind a service action's request, when jsonRPCServiceEntrypoint serves it (to tell a notification from a request, or read the transport).

Parameters

context

ServiceContext

The service action's context (this.context in a controller).

Returns

JSONRPCRequestInfo | undefined

The request's method, id and transport, or undefined when another adapter serves the request.

Example

import {Controller, ServiceContext} from 'lakutata/com/entrypoint'
import {ServiceAction} from 'lakutata/decorator/ctrl'
import {jsonRPCRequestOfContext, type JSONRPCRequestInfo} from 'lakutata/adapter/jsonrpc'

class LogController extends Controller {
    //{"jsonrpc": "2.0", "method": "log.write", "params": {"line": "started"}}: a notification, no id
    @ServiceAction({method: 'log.write'})
    public async write(input: {line: string}): Promise<void> {
        const request: JSONRPCRequestInfo | undefined = jsonRPCRequestOfContext(this.context as ServiceContext)
        console.log(`${request?.transport}: ${input.line}`)
    }
