module: [kind=event] websocket_message

The @{websocket_message} event is fired when a message is received on an open WebSocket connection.

This event is normally handled by @{http.Websocket.receive}, but it can also be pulled manually.

Return Values

1. @{string}: The event name.
2. @{string}: The URL of the WebSocket.
3. @{string}: The contents of the message.
4. @{boolean}: Whether this is a binary message.

Example

Prints a message sent by a WebSocket:

local myURL = "wss://example.tweaked.cc/echo"
local ws = http.websocket(myURL)
ws.send("Hello!")
local event, url, message
repeat
    event, url, message = os.pullEvent("websocket_message")
until url == myURL
print("Received message from " .. url .. " with contents " .. message)
ws.close()
