The [websocket_closed] event is fired when an open WebSocket connection is closed.

Return Values

  1. [string]: The event name.
  2. [string]: The URL of the WebSocket that was closed.
  3. [string]|[nil]: The server-provided reason the websocket was closed. This will be [nil] if the connection was closed abnormally.
  4. [number]|[nil]: The connection close code, indicating why the socket was closed. This will be [nil] if the connection was closed abnormally.

Example

local ws = http.websocket(myURL)
local event, url
repeat
    event, url = os.pullEvent("websocket_closed")
until url == myURL
print("The WebSocket at " .. url .. " was closed.")
