Parameters and methods 参数与方法

更多http context选项, 详见php.net

// construct usage
$client = new Roiwk\SSEClient\Client('http://127.0.0.1:8888', [
    'retryInterval' => 3,
    'onmessage' => function(string $data){},
    'streamContextOptions' => [
        'http' => [
            'method' => 'POST',
            'header' => [
                'Content-Type: application/json',
            ],
            'content' => json_encode(['test' => 1]),
        ],
    ],
]);

// method usage
$client->addEventListener('ping', function ($data) {
    echo "Received ping event: $data\n";
});

$client->onmessage(function(string $data) use ($client){
    echo $data.PHP_EOL;
    $iWantClose = true;
    if ($iWantClose) {
        $client->close();
    }
});

$client->setRetryInterval(1);

$client->start();

Tips

  1. If the server sends messages without an event field, those messages are treated as message events.
  2. 如果服务器发送的消息中没有 event 字段,则这些消息会被视为 message 事件。
  1. The close method can be executed in the callback, for example: addEventListener and onmessage, onerror.
  2. close方法可以在回调中执行, 例如:addEventListener和onmessage,onerror.
