在 Node.js 中使用 Flash 套接字 [英] Using a Flash socket with Node.js

问题描述

我一直在使用 gimite/web-socket-js 来实现 WebSocket过去只是 Chrome 和 Safari 的开发版本.我想从 Ruby 服务器转移到 Node.js.突然它在 Chrome 之外的任何东西都不起作用.

I've been using gimite / web-socket-js to implement a WebSocket past simply Chrome and development builds of Safari. I want to move away from the Ruby server and onto Node.js. Suddenly it doesn't work in anything but Chrome.

我怀疑这与 Flash Socket Policy 文件有关我需要实施.我想将其实现为外部 Node.js 进程，以免与原始应用程序混淆.我正在使用 node-websocket-server 用 Node.js 实现 WebSocket 协议，并且同样，我也希望 不要 搞砸.

I suspect that this has to do with the Flash Socket Policy file that I need to implement. I would like to implement this as an external Node.js process so as not to muddy with the original application. I am using the node-websocket-server for implementing WebSocket protocol with Node.js, and again I would prefer to not mess with that either.

似乎最简单的方法就是运行 flashsocket.js，但运行它给了我以下错误:

It seemed like the simplest thing to do would be to run flashsocket.js, but running that gives me the following error:

sys:334
    ctor.prototype = Object.create(superCtor.prototype, {
                            ^
TypeError: Object prototype may only be an Object or null

    at Module.loadSync (node.js:349:12)
    at Object.runMain (node.js:532:24)
    at node.js:762:10

这里我们遇到了 Node.js 喜欢的可爱的神秘错误.

Here we run into the lovely cryptic errors Node.js is loved for.

我的问题是是否有一个独立的全局闪存套接字策略服务器，我可以运行 Node.js 或其他应用程序?我的理解是我只需要让它驻留在端口 843 上.或者是否有另一个用于 Node.js 的 WebSocket 库可以像 Ruby 服务器那样处理 Flash 策略?

My question is is there a stand alone global flash socket policy server I can run off of either Node.js or another application? My understanding is that I only need to have it reside on port 843. Or is there another WebSocket library for Node.js that will handle the Flash Policy like the Ruby server does?

推荐答案

在 Node.js 邮件列表的帮助下，我想出了以下内容:

With a bit of help from the Node.js mailing list I came up with the following:

var net = require("net"),
    domains = ["localhost:8081"];

net.createServer(
    function(socket)
    {
        socket.write("<?xml version=\"1.0\"?>\n");
        socket.write("<!DOCTYPE cross-domain-policy SYSTEM \"http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd\">\n");
        socket.write("<cross-domain-policy>\n");

        domains.forEach(
            function(domain)
            {
                var parts = domain.split(':');
                socket.write("<allow-access-from domain=\""+parts[0]+"\"to-ports=\""+(parts[1]||'80')+"\"/>\n");
            }
        );

        socket.write("</cross-domain-policy>\n");
        socket.end();   
    }
).listen(843);

我还为 WebSockets 应用程序编写了(简要)教程使用 Flash 套接字.
