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()

Ruby

require 'chilkat'

success = false

# 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.
rest = Chilkat::CkRest.new()
success = rest.Connect("192.168.1.35",80,false,false)
if (success != true)
    print rest.lastErrorText() + "\n";
    exit
end

ws = Chilkat::CkWebSocket.new()

# Tell the WebSocket to use this connection.
success = ws.UseConnection(rest)
if (success != true)
    print ws.lastErrorText() + "\n";
    exit
end

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

# Now send the GET request to /websockets.
responseBody = rest.fullRequestNoBody("GET","/websockets")
if (rest.get_LastMethodSuccess() != true)
    print rest.lastErrorText() + "\n";
    exit
end

# 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..)
statusCode = rest.get_ResponseStatusCode()
print "Response status code: " + statusCode.to_s() + "\n";

if (statusCode != 101)
    print responseBody + "\n";
    print "-- Failed because of unexpected response status code." + "\n";
    exit
end

# We have the expected 101 response, so let's now validate the 
# contents of the response.
success = ws.ValidateServerHandshake()
if (success != true)
    print ws.lastErrorText() + "\n";
    exit
end

print "WebSocket connection successful." + "\n";

# 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.
finalFrame = true
success = ws.SendFrame("http.controller_login:username=xxx&password=xxxxx",finalFrame)
if (success != true)
    print ws.lastErrorText() + "\n";
    exit
end

# Read an incoming frame.
success = ws.ReadFrame()
if (success != true)
    print "Failed to receive a frame" + "\n";
    print "ReadFrame fail reason = " + ws.get_ReadFrameFailReason().to_s() + "\n";
    print ws.lastErrorText() + "\n";
    exit
end

# Show the string that was received.
receivedStr = ws.getFrameData()
print "Received: " + receivedStr + "\n";

# Continue with whatever additional communications are desired...
