Usage

To use wsget, you need to specify the WebSocket URL:

wsget wss://ws.postman-echo.com/raw

You also can pass the initial request as part command line argument by using flag -r

wsget wss://ws.postman-echo.com/raw -r "Hello world!"

By default, wsget will print the data received from the WebSocket server only to the console. You can also save the data to a file using the -o flag:

wsget wss://ws.postman-echo.com/raw  -o output.txt

Example:

wsget "wss://ws.derivws.com/websockets/v3?app_id=1" -r '{"time":1}'
Use Enter to input request and send it, Ctrl+C to exit
->
{
  "time": 1
}
<-
{
  "echo_req": {
    "time": 1
  },
  "msg_type": "time",
  "time": 1698555261
}
