Websocket与Perl CGI

Question

下面是我的JavaScript代码：

ws = new WebSocket('ws://www.crazygao.com:3000'); // test
ws.onopen = function() {
    alert('Connection is established!'); // test
};
ws.onclose = function() {
    alert('Connection is closed'); 
};
ws.onmessage = function(e) {
    var message = e.data;
    //alert('Got new message: ' + message);
};
ws.onerror = function(e) {
    //var message = e.data;
    alert('Error: ' + e);
};

下面是我的Perl脚本测试代码：

use HTTP::Daemon;
use HTTP::Status;

my $d = HTTP::Daemon->new(
    LocalAddr => 'www.crazygao.com',
    LocalPort => 3000
) || die; print "Please contact me at: <URL:", $d->url, ">\n";
while(my $c = $d->accept) {
    $c->send_response("1"); # test
    while (my $r = $c->get_request) {
        if ($r->method eq 'GET') {
            $c->send_response("...");
        }
    }
    $c->close;
    undef($c);
}

当页面加载时，连接立即关闭，在Chrome控制台窗口中，我看到以下错误：到“ws://198.38.89.14:3000/”的WebSocket连接失败：连接建立错误:NET::err_connection_rejected

我的问题是，如果是这样，我怎样才能做到这一点？

Answer 1

我知道这是旧的，我来这里是因为我自己在寻找答案。最后，我自己通过使用Net：：WebSocket：：Server找到了答案。

http://search.cpan.org/~topaz/net-websocket-server-0.003004/lib/net/websocket/server.pm了解如何使用该模块和示例的更多细节。

基本上，您将使用以下perl代码来匹配javascript（从Net：：WebSocket：：Server的CPAN页面复制和修改）：

use Net::WebSocket::Server;

my $origin = 'http://www.crazygao.com';

Net::WebSocket::Server->new(
    listen => 3000,
    on_connect => sub {
        my ($serv, $conn) = @_;
        $conn->on(
            handshake => sub {
                my ($conn, $handshake) = @_;
                $conn->disconnect() unless $handshake->req->origin eq $origin;
            },
            utf8 => sub {
                my ($conn, $msg) = @_;
                $_->send_utf8($msg) for $conn->server->connections;
            },
            binary => sub {
                my ($conn, $msg) = @_;
                $_->send_binary($msg) for $conn->server->connections;
            },
        );
    },
)->start;
