Swoole 개발 기능의 네트워크 통신 암호화 및 복호화에 대한 심층 연구

// 创建一个TCP服务器
$server = new SwooleServer("0.0.0.0", 9501);

// 设置加密密钥
$key = '1234567890abcdef';

// 监听连接事件
$server->on('connect', function ($server, $fd) use ($key) {
    echo "Client {$fd} connected.
";
});

// 监听数据接收事件
$server->on('receive', function ($server, $fd, $fromId, $data) use ($key) {
    echo "Received data from Client {$fd}: {$data}
";

    // 数据加密
    $encryptedData = openssl_encrypt($data, 'AES-128-ECB', $key, OPENSSL_RAW_DATA);

    // 发送加密后的数据给客户端
    $server->send($fd, $encryptedData);
});

// 启动服务器
$server->start();

// 创建一个TCP客户端
$client = new SwooleClient(SWOOLE_SOCK_TCP);

// 设置服务器连接参数
$client->set([
    'open_eof_check' => true,
    'package_eof' => "
",
]);

// 连接到服务器
if (!$client->connect('127.0.0.1', 9501)) {
    die("Connect failed.");
}

// 设置加密密钥
$key = '1234567890abcdef';

// 监听数据接收事件
$client->on('receive', function($cli, $data) use ($key) {
    echo "Received encrypted data from Server: {$data}
";

    // 数据解密
    $decryptedData = openssl_decrypt($data, 'AES-128-ECB', $key, OPENSSL_RAW_DATA);

    echo "Decrypted data: {$decryptedData}
";
});

// 发送数据给服务器
$client->send("Hello, Server!
");

// 关闭连接
$client->close();
