websocket 服务，很大概率会出现连接失败的现像

### 问题描述
js 端 new WebSocket("ws://ip:port") 后，有时连接正常，有时连接失败，失败时提示：Error during WebSocket handshake: Unexpected response code: 302

### Swoole版本，PHP版本，以及操作系统版本信息
Swoole: 4.4.19
PHP: 7.2.9 (cli) (built: Sep  9 2018 10:38:07) ( ZTS )
OS: Linux version 3.10.0-693.2.2.el7.x86_64 (builder@kbuilder.dev.centos.org) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-16) (GCC) ) #1 SMP Tue Sep 12 22:26:13 UTC 2017

### 相关代码
```javascript
//javascript 
var ws = new WebSocket("ws://ip:port");
```

```php
//php
$server = new Server($listenIP, $listenPort, SWOOLE_PROCESS, SWOOLE_TCP);

$server->set([
            'daemonize' => $daemonize,
            'pid_file' => $pidFile,
            'log_file' => $logFile,
            'reactor_num' => $cpuNums,
            'worker_num' => $cpuNums,
            'max_request' => $maxRequest,
            'dispatch_mode' => 5,
            'heartbeat_check_interval' => 15,
            'heartbeat_idle_time' => 30,
            'open_cpu_affinity' => true,
]);

//绑定事件
$server->on('start', "Event::onStart");
$server->on('open', "Event::onOpen");
$server->on('workerStart', "Event::onWorkerStart");
$server->on('message', "Event::onMessage");
$server->on('close', "Event::onClose");

$process = new Process(function () use ($server) {
     //子进程逻辑
});
$server->addProcess($process);

```

### 你期待的结果是什么？实际看到的错误信息又是什么？
期待服务启动后，websocket 客户端每次都能正常连接
