PHP Swoole 协程,异步消息不是异步的

问题描述

我正在运行 Swoole WebSocket 服务器,并且正在尝试在脚本运行时向最终用户发送消息。我遇到的问题是消息不是异步发送的,只有在脚本完成执行后才会发送。哪一种违背了目的。

我的问题的精简版如下:

# Recipient IDs
$fd = [75371];
# Message to recipient
$message = "Ping";

# Let's send the message as a coroutine
go(function() use ($fd,$message){
    print "About to send message [{$message}] to recipients ".json_encode($fd).PHP_EOL;
    # Connect to the WebSocket and send the message
    $client = new \Swoole\Coroutine\Http\Client(0.0.0.0,1234);
    $client->upgrade("/");
    $client->push(json_encode([
        "fd" => $fd,"data" => $message
    ]));
    $client->close();
    print "Finally the message was sent".PHP_EOL;
});

# Coroutine script is done,let's continue with our other tasks
print "But wait,I'm gonna be busy with other tasks for 5 seconds first".PHP_EOL;
sleep(5); // This simulates process intensive tasks

# Another coroutine,not related
go(function() {
    print "Gonna be busy again again for another 5 seconds".PHP_EOL;
    co\System::sleep(5);
    print "And we're done".PHP_EOL;
});

我的印象是协程中的命令将一个单独的线程执行,我的意思是线程不会关心父脚本线程中发生的事情,因为它在做自己的事情。

好像不是这样。在消息发送之前,脚本会继续运行,直到我们完成下面的“任务”,消息才最终被发送。我期待的顺序如下:

About to send message [Ping] to recipients [75371]
Finally the message was sent
But wait,I'm gonna be busy with other tasks for 5 seconds first
Gonna be busy again again for another 5 seconds
And we're done

但我得到的顺序如下:

About to send message [Ping] to recipients [75371]
But wait,I'm gonna be busy with other tasks for 5 seconds first
Gonna be busy again again for another 5 seconds
Finally the message was sent
And we're done

我对协程有什么误解?我已经将协程作为一个实际的独立 PHP 线程来执行。然后它起作用了,但这似乎有点适得其反,因为我认为协程线程。 一切都必须在一个协程中才能工作吗?
