Websocket+HTTP Hybrid Server

[kingIZZZY]

Content

✅ Swoole supports Hybrid WebSocket+HTTP Server

• Swoole\WebSocket\Server extends Swoole\Http\Server and can receive onRequest

✅ Hyperf supports Hybrid WebSocket+HTTP Server

• See Hyperf Docs "Handle Http Request in Websocket Server"

❌ Hypervel loses hybrid server capability?

• Hypervel introduces "Kernels" (I think)
  • hypervel/foundation/src/Http/Kernel.php
  • hypervel/foundation/src/Http/WebsocketKernel.php
• we can only choose 1 kernel per config/server.php server configuration?

  components/src/foundation/src/Providers/FoundationServiceProvider.php

  Line 138 in 12e5145

  foreach ($this->config->get('server.kernels', []) as $server => $kernel) {

Can we please support Hybrid WebSocket+HTTP Server in Hyperf 🙏

In my specific case: I need custom CoreMiddleware (override in config/dependencies.php) but only one Kernerl/WebSocketKernel's middleware is used.

I made it work by

• overriding my own Hypervel\Foundation\Http\Kernel and Hypervel\Foundation\Http\WebsocketKernel
• config/server.php has 4 callback events
  • 1 for http onRequest referring to my Http Kernel override
  • 3 for websocket onHandShake + onMessage + onClose referring to my WebsocketKernel override

'callbacks' => [
    Event::ON_REQUEST => ['HttpServer', 'onRequest'],
    Event::ON_HAND_SHAKE => [MyWebsocketKernel::class, 'onHandShake'],
    Event::ON_MESSAGE => [MyWebsocketKernel::class, 'onMessage'],
    Event::ON_CLOSE => [MyWebsocketKernel::class, 'onClose'],
],

• config/server.php kernels has 'http' => MyWebsocketKernel::class (i'm not even sure what this does / how this affects anything)
• Make CoreMiddleware overrides for Hyperf\WebSocketServer\CoreMiddleware and Hyperf\Http\CoreMiddleware for each of the kernels

// dependencies.php
return [
    'HttpServer' => App\Http\MyHttpKernel::class,
    Hyperf\HttpServer\CoreMiddleware::class => App\Http\Middleware\MyCoreMiddleware::class,
    Hyperf\WebSocketServer\CoreMiddleware::class => App\Http\Middleware\MyWebSocketCoreMiddleware::class,
];
