swoole websocket服务器中添加监听tcp的端口

Question

在websocket服务器中监听tcp的9501端口代码如下:

 $aa = $this->server->listen('127.0.0.1',9501,SWOOLE_SOCK_TCP);
        $aa->set([
                'open_length_check' => true,
                 'package_length_type' => 'N',
                 'package_length_offset' => 0,
                 'package_max_length' => 8000000,
        ]);

        $aa->on('receive',function ($serv,$fd,$from_id,$data){
                $websocket = $this->server->ports[0];
                foreach ($websocket->connections as $_fd) {
                  var_dump($_fd);
                  if ($server->exist($_fd)) {
                         $server->push($_fd, "this is server onReceive");
                 }
                }
        });
        $this->server->on('close', function ($ser, $fd) {
            echo "client {$fd} closed\n";
        });

报错信息是:

[2020-06-05 09:25:22 #12948.3]    WARNING    swProtocol_recv_check_length (ERRNO 1201): package is too big, remote_addr=unknown:0, length=1751477360

就是个普通的监听,包能到达1个g,请问这是不是不正常

swoole 客户端:

<?php

$client = new Swoole\Client(SWOOLE_SOCK_TCP);
if (!$client->connect('127.0.0.1', 9501, -1)) {
    exit("connect failed. Error: {$client->errCode}\n");
}
$client->send("hello world\n");
//echo $client->recv();
$client->close();

Answer 1

你服务端启用了包长检测，客户端没有进行处理，所以报错了。

$pkg = "hello world\n";
$client->send(pack('N', strlen($pkg)) . $pkg);

Answer 2

数据包太大；
