Web GPS

  • URL

    /gps/web/update.cmd

    POST

  • Role

    admin

  • POST parameters

    HTTP error on failure

WebGPS Websocket

Kismet supports a Web-based GPS, where the data is provided by the browser (or submitted over the HTTP channel from another GPS source). The websocket interface allows a continual update on a single connection.

  • URL

    /gps/web/update.ws

  • API Added

    2021-08

  • Methods

    WEBSOCKET (HTTP Upgrade + Websocket handshake)

  • Role

    admin, WEBGPS

  • URI parameters

    Key Description
    user Kismet administrative username, as HTTP URI-encoded variable
    password Kismet administrative password, as HTTP URI-encoded variable
    KISMET Kismet auth cookie, as HTTP URI-encoded variable

  • Websocket interface

    The websocket subscription API accepts JSON data posting an updated GPS location.

    The JSON data should contain:

    Key Description
    lat GPS latitude
    lon GPS longitude
    alt Optional, GPS altitude in meters
    spd Optional, GPS speed in kilometers per hour

  • Result

    A valid location update receives a websocket response of: {"update": "ok"} An invalid location update receives a websocket response of: {"update": "error"} and Kismet may terminate the connection

  • Notes

    Kismet websockets will accept authentication as HTTP basic auth headers, Kismet session token cookies, or HTTP URI-encoded GET parameters of the basic auth or session cookie.

    Some tools (websocat, others) allow sending HTTP basic auth as part of the URI (ws://user:pass@host:port/eventbus/events.ws). However, modern browser implementations do not support this, and websockets must be constructed using GET parameters, such as ws://host:port/eventbus/events.ws?user=username&password=userpass.

    Websocket URIs must match the content type of the calling page; a https page must use the wss URI and a http page must use the ws URI. The Kismet UI detects this via javascript, but other implementations must provide a similar match.
