Linux下类取到的静态成员变量为null

你想具体做什么

为了复用EventSource的长连接，我把$request->connection存放在一个自己写的类(PRefsGlobal)的成员变量下面(尝试过把这个静态类文件放在support目录下面并配置自动加载，或者把这个文件直接放到model下)，并且在与其他进程通信的时候从里面拿出来推送信息给用户。

程序代码

public function load(Request $request)
    {
        $dirname = $request->get('dirname');
        if (!empty($dirname) && file_exists($dirname)) {
            $task_connection = new AsyncTcpConnection('text://0.0.0.0:8888');
            $task_connection->send(loadmsg($dirname));
            $task_connection->onMessage = function (AsyncTcpConnection $task_connection, $task_result) {

                PRefsGlobal::get("loadsse")->send(ssemessage($task_result));
                if ($task_result == "Loading finished.") {
                    $task_connection->close();
                    PRefsGlobal::get("loadsse")->close();
                }
            };
            $task_connection->connect();
            return ok("success");
        }
        return error(404, "Wrong dirname!");
    }
public function loadsse(Request $request)
    {
        return $this->establishsse($request, "loadsse");
    }
private function establishsse(Request &$request, $name)
    {
        $connection = $request->connection;
        if ($request->header('accept') === 'text/event-stream') {
            // 首先发送一个 Content-Type: text/event-stream 头的响应
            $connection->send(new Response(200, ['Content-Type' => 'text/event-stream', 'Access-Control-Allow-Origin' => '*']));
            PRefsGlobal::set($name, $connection);
            return new ServerSentEvents(['event' => 'message', 'data' => 'hello', 'id' => 1]);
        }
        return ok("ok");
    }
