Open Swoole TLS and HTTPS

Generate SSL certificate for your development environment with mkcert

You can use mkcert to generate SSL certificate and setup CA at your local development environment.

mkcert -install

# Created a new local CA 💥
# The local CA is now installed in the system trust store! ⚡️
# The local CA is now installed in the Firefox trust store (requires browser restart)! 🦊

mkcert example.com "*.example.com" example.test localhost 127.0.0.1 ::1

#Created a new certificate valid for the following names 📜
# - "example.com"
# - "*.example.com"
# - "example.test"
# - "localhost"
# - "127.0.0.1"
# - "::1"

# The certificate is at "./example.com+5.pem" and the key at "./example.com+5-key.pem" ✅

Enable HTTPS at Open Swoole Server?

You can enable SSL for HTTP, HTTP2 or WebSocket server with the following settings:

<?php
$server->set([
    'ssl_cert_file' => __DIR__ . '/config/example.com+5.pem',
    'ssl_key_file' => __DIR__ . '/config/example.com+5-key.pem'
]);

You an find other SSL configrations at Open Swoole Server Configuration.

You have to pass OpenSwoole\Constant::SSL when defining a Open Swoole server to enable SSL:

use OpenSwoole\Server;
use OpenSwoole\Constant;

$server = new Server("0.0.0.0", 9501, Server::PROCESS, Constant::SOCK_TCP | Constant::SSL);
