为什么websocket连接中断

Question

在我对websocket echo服务器运行客户端后,它会在大约半分钟后与WebSocket closed with status 1006消息断开连接.

请建议如何避免此类行为(浏览器客户端似乎没有受到影响)

use 5.20.0;
use Mojo::UserAgent;
use Mojo::IOLoop;

sub ws_connect {

  state $ua;

  say "Connecting..";
  $ua = Mojo::UserAgent->new;
  $ua->websocket('ws://127.0.0.1:3000/echo' => \&onConnect);

}

sub onConnect {
  my ($ua, $tx) = @_;

  if (!$tx->is_websocket) {
        say 'WebSocket handshake failed!';
  }
  say "Connected!";

  $tx->on(finish => sub {
        my ($tx, $code) = @_;
        say "WebSocket closed with status $code";
  });

}

ws_connect();
Mojo::IOLoop->start;

回声服务器

use Mojolicious::Lite;
use Mojo::EventEmitter;

helper events => sub { state $events = Mojo::EventEmitter->new };

# get '/' => 'chat';

websocket '/echo' => sub {
  my $c = shift;

  $c->inactivity_timeout(3600);

  # Forward messages from the browser
  $c->on(message => sub { shift->events->emit(mojochat => shift) });

  # Forward messages to the browser
  my $cb = $c->events->on(mojochat => sub { $c->send(pop) });
  $c->on(finish => sub { shift->events->unsubscribe(mojochat => $cb) });
};

app->start;

如果客户端和服务器之间没有数据，则可能已达到不活动超时。

您是否尝试过增加inactivity_timeout？（或者您可以简单地将其设置0为无限不活动）
