我使用PHP开发了WebSocket服务器,并且可以与ws://一起正常工作,但是在生产环境中,它使用https://,那么我必须使用wss://。
我应该使用证书启动套接字还是类似的东西?我无法解析标题以完成握手。
如何在https服务器后面执行握手?
这是具有Amazon证书的AWS EC2计算机。
我尝试将.pem文件导入套接字初始化,在我的https://环境后面运行ws://,但没有任何效果:(
套接字初始化:
$socket = stream_socket_server(
"tcp://0.0.0.0:" . env("APP_WSS_PORTA"),
$errno,
$errstr
);
我也尝试过:
use Aws\Acm\AcmClient;
$cert = (new AcmClient(include config_path('aws.php')))->GetCertificate([
"CertificateArn" => "arn:aws:acm:sa-east-1:EDITED_TO_STACKOVERFLOW"
])["CertificateChain"];
$cert_path = "cert.pem";
file_put_contents(base_path($cert_path), $cert);
$context = stream_context_create(
["ssl" => ["local_cert"=> $cert_path]]
);
$socket = stream_socket_server(
"tcp://0.0.0.0:" . env("APP_WSS_PORTA"),
$errno,
$errstr,
STREAM_SERVER_BIND|STREAM_SERVER_LISTEN,
$context
);
我的握手功能:
function wsHandshake($data)
{
echo "> Handshake " . remoteIp() . PHP_EOL;
$lines = preg_split("/\r\n/", $data);
$headers = array();
foreach ($lines as $line) {
$line = chop($line);
if (preg_match('/\A(\S+): (.*)\z/', $line, $matches)) {
$headers[$matches[1]] = $matches[2];
}
}
var_dump($data); // to debug it :)
if (!isset($headers['Sec-WebSocket-Version']) || $headers['Sec-WebSocket-Version'] < 6) {
echo '> Versao do WebSocket nao suportada' . PHP_EOL;
return false;
}
$sec_accept = base64_encode(pack('H*', sha1($headers['Sec-WebSocket-Key'] . '258EAFA5-E914-47DA-95CA-C5AB0DC85B11')));
$response = "HTTP/1.1 101 Switching Protocols\r\n";
$response .= "Upgrade: websocket\r\n";
$response .= "Connection: Upgrade\r\n";
$response .= "Sec-WebSocket-Accept: " . $sec_accept . "\r\n";
$response .= "\r\n";
return $response;
}
带有ws://
的var_dumpstring(448) "GET / HTTP/1.1
