(PHP ActiveX) Duplicate Python websocketsSee more WebSocket ExamplesDemonstrates 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()
<?php // 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. // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Rest') $rest = new COM("Chilkat.Rest"); $success = $rest->Connect('192.168.1.35',80,0,0); if ($success != 1) { print $rest->LastErrorText . "\n"; exit; } // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.WebSocket') $ws = new COM("Chilkat.WebSocket"); // Tell the WebSocket to use this connection. $success = $ws->UseConnection($rest); if ($success != 1) { print $ws->LastErrorText . "\n"; exit; } // 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->LastMethodSuccess != 1) { print $rest->LastErrorText . "\n"; exit; } // 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->ResponseStatusCode; print 'Response status code: ' . $statusCode . "\n"; if ($statusCode != 101) { print $responseBody . "\n"; print '-- Failed because of unexpected response status code.' . "\n"; exit; } // We have the expected 101 response, so let's now validate the // contents of the response. $success = $ws->ValidateServerHandshake(); if ($success != 1) { print $ws->LastErrorText . "\n"; exit; } 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 = 1; $success = $ws->SendFrame('http.controller_login:username=xxx&password=xxxxx',$finalFrame); if ($success != 1) { print $ws->LastErrorText . "\n"; exit; } // Read an incoming frame. $success = $ws->ReadFrame(); if ($success != 1) { print 'Failed to receive a frame' . "\n"; print 'ReadFrame fail reason = ' . $ws->ReadFrameFailReason . "\n"; print $ws->LastErrorText . "\n"; exit; } // Show the string that was received. $receivedStr = $ws->getFrameData(); print 'Received: ' . $receivedStr . "\n"; // Continue with whatever additional communications are desired... // .... // ?> |
