我一直在尝试让Fleck（C# websocket 服务器实现）中的 echo 服务器示例与web-socket-js（用于旧版浏览器的闪存驱动的 websocket）一起工作，并且遇到了问题。

我遇到的第一个问题是从端口 843 上传客户端访问策略。我放弃了，只是在 Fleck 的 WebSocketConnection 读取方法中添加了一些快速而肮脏的代码......

        if (body.StartsWith("<policy-file-request/>"))
        {
            FleckLog.Debug("Reveived Flash Policy File Request");

            var policyFile = @"<?xml version=""1.0""?><!DOCTYPE cross-domain-policy SYSTEM ""http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd""><cross-domain-policy><allow-access-from domain=""*"" to-ports=""*""/></cross-domain-policy>";
            byte[] bytes = new System.Text.UTF8Encoding().GetBytes(policyFile);

            Socket.Stream.Write(bytes, 0, bytes.Length);
            Socket.Stream.WriteByte(0);
            Socket.Stream.WriteByte(13);

            FleckLog.Debug("Flash Policy File Sent");

            return;
        }

现在它似乎挂了。这是日志...

从 Fleck 回声服务器我得到这个......

有没有人让这两个库相处？我正在使用 IE 9.0、Flash 11.5.502.110 和 .NET 4.0。此示例与带有 IE 9.0、Flash 11.5.502.110 的 web-socket-ruby/samples/echo_server.rb 完美配合，并且 Fleck 示例回显服务器与 Firefox/Chrome/etc 完美配合...

找到了。用于解析 Web Socket 请求中的标头的 Fleck 正则表达式过于严格，并且需要 Flash 客户端未提供的换行符。

const string pattern = @"^(?<method>[^\s]+)\s(?<path>[^\s]+)\sHTTP\/1\.1\r\n" + // request line
                       @"((?<field_name>[^:\r\n]+):\s(?<field_value>[^\r\n]+)\r\n)+" + //headers
                       @"\r\n" + //newline*
                       @"(?<body>.+)?";
