Duplicate Python websockets

See more WebSocket Examples

Demonstrates how to duplicate the following Python client-side websocket snippet:

async with websockets.connect('ws://192.168.1.35/websocket') as websocket:
await websocket.send("http.controller_login:username=xxx&password=xxxxx")
response = await websocket.recv()

;  This example requires the Chilkat API to have been previously unlocked.
;  See Global Unlock Sample for sample code.

;  In Python, the following line of code does more than just connect:
;  
;       websockets.connect('ws://192.168.1.35/websocket')
;  
;  It is connecting to 192.168.1.35 without using TLS.  If the URI starts with "wss://", then TLS should be used.
;  But this URI begins with just "ws:/", so no TLS.

;  Also, after connecting, a GET request is sent to the /websocket endpoint.
;  In summary, the websockets.connect function is establishing the connection and it sends a GET request.

;  First establish the connection.
;  No TLS, use the default HTTP port 80.
$oRest = ObjCreate("Chilkat.Rest")

;  Tell the WebSocket to use this connection.
$bSuccess = $oWs.UseConnection($oRest)
If ($bSuccess <> True) Then
    ConsoleWrite($oWs.LastErrorText & @CRLF)
    Exit
EndIf

;  Add the standard WebSocket open handshake headers that will be needed.
;  (This adds the required HTTP request headers to the rest object.)
$oWs.AddClientHeaders()

;  Now send the GET request to /websockets.
Local $sResponseBody = $oRest.FullRequestNoBody("GET","/websockets")
If ($oRest.LastMethodSuccess <> True) Then
    ConsoleWrite($oRest.LastErrorText & @CRLF)
    Exit
EndIf

;  If successful, the HTTP response status code should be 101,
;  and the response body will be empty. (If it failed, we'll have a look
;  at the response body..)
Local $iStatusCode = $oRest.ResponseStatusCode
ConsoleWrite("Response status code: " & $iStatusCode & @CRLF)

If ($iStatusCode <> 101) Then
    ConsoleWrite($sResponseBody & @CRLF)
    ConsoleWrite("-- Failed because of unexpected response status code." & @CRLF)
    Exit
EndIf

;  We have the expected 101 response, so let's now validate the 
;  contents of the response.

;  The application may now begin sending and receiving frames on the WebSocket connection.

;  The 1st frame sent by the Python snippet is:
;  
;      websocket.send("http.controller_login:username=xxx&password=xxxxx")
;  

;  Send the same using Chilkat, and get the response.
