Google Places

Technical Preview

Overview

Client-mode REST API connectors for Google Maps Platform: geocoding, elevation, time zone, device geolocation, Routes API ETAs and matrices, Roads API snap to roads and speed limits, Places search, Address Validation, Weather and Air Quality. This is one of the templates in the Google Maps Platform REST API app (google-maps-platform). Deploy it alongside the other connectors of that app when they depend on each other (for example a token connector plus an API connector).

Auth

schemes: [“API key query parameter key= (Geocoding, Elevation, Time Zone, Geolocation, Roads, Address Validation, Weather, Air Quality)”, “X-Goog-Api-Key header + required X-Goog-FieldMask header (Routes API, Places API (New))”]
secrets: [“GOOGLE_MAPS_API_KEY”]
note: OAuth 2.0 service accounts not packaged (Fleet Engine and Route Optimization need OAuth).

Auth headers used by the template: X-Goog-Api-Key: {value.json.apikey}.

Template parameters

Placeholder	Type	Description	Required
`RouteName`	string	Name of the Google Places connector	no
`BaseUrl`	string	Google Places base URL without trailing slash (e.g. https://places.googleapis.com)	yes

BASE_ADDRESS default: https://places.googleapis.com.

Deploy

Get the template card (JSON with template and metadata) from the broker, then deploy the connector:

mosquitto_pub -t '$SYS/Coreflux/Command' -m "-connectorCode GOOGLE_PLACES"

The deployable connector from the REST API app, with BASE_ADDRESS already filled in:

DEFINE CONNECTOR GooglePlaces WITH TYPE REST_API
    ADD REST_API_CONFIG
        WITH BASE_ADDRESS "https://places.googleapis.com"
        WITH ENABLE_CLIENT "true"
        WITH USE_SSL "true"
        WITH REQUEST_TIMEOUT '30'
        WITH DEFAULT_CONTENT_TYPE "application/json"
    ADD EVENT SearchText
        WITH SOURCE_TOPIC "fleet/google-maps/places/search/text"
        WITH DESTINATION_TOPIC "fleet/google-maps/places/search/text/response"
        WITH METHOD "POST"
        WITH ENDPOINT "/v1/places:searchText"
        WITH HEADERS
            ADD "Accept" "application/json"
            ADD "User-Agent" "Coreflux-Broker REST_API route (https://www.coreflux.org)"
            ADD "X-Goog-Api-Key" "{value.json.apikey}"
            ADD "X-Goog-FieldMask" "{value.json.fieldmask}"
            ADD "Content-Type" "application/json"
        WITH BODY "{value.json.body}"
    ADD EVENT SearchNearby
        WITH SOURCE_TOPIC "fleet/google-maps/places/search/nearby"
        WITH DESTINATION_TOPIC "fleet/google-maps/places/search/nearby/response"
        WITH METHOD "POST"
        WITH ENDPOINT "/v1/places:searchNearby"
        WITH HEADERS
            ADD "Accept" "application/json"
            ADD "User-Agent" "Coreflux-Broker REST_API route (https://www.coreflux.org)"
            ADD "X-Goog-Api-Key" "{value.json.apikey}"
            ADD "X-Goog-FieldMask" "{value.json.fieldmask}"
            ADD "Content-Type" "application/json"
        WITH BODY "{value.json.body}"
    ADD EVENT GetPlace
        WITH SOURCE_TOPIC "fleet/google-maps/places/get"
        WITH DESTINATION_TOPIC "fleet/google-maps/places/get/response"
        WITH METHOD "GET"
        WITH ENDPOINT "/v1/places/{value.json.placeid}?languageCode=en{value.json.params}"
        WITH HEADERS
            ADD "Accept" "application/json"
            ADD "User-Agent" "Coreflux-Broker REST_API route (https://www.coreflux.org)"
            ADD "X-Goog-Api-Key" "{value.json.apikey}"
            ADD "X-Goog-FieldMask" "{value.json.fieldmask}"

Deploy it with -addConnector (do not include ADD METADATA).

Usage example

Call SearchText by publishing a JSON payload to its request topic, and read the reply on the response topic:

mosquitto_sub -t 'fleet/google-maps/places/search/text/response' &
mosquitto_pub -t 'fleet/google-maps/places/search/text' -m '{"apikey": "<apikey>", "body": {}, "fieldmask": "<fieldmask>"}'
