无法连接到同一域中的套接字
我有一个 Flex Web 应用程序（编译为常规 SWF），它尝试连接到其自己的服务器上的（二进制，而不是 XML）套接字。因此，如果 swf 位于 example.com/app.swf，则套接字为 example.com:12869
这应该是可能的，AFAIK，但是当我尝试连接时收到安全错误，指出 example.com/app.swf 无法访问 example.com:12869。
尽管不需要它，我也有一个包含
<cross-domain-policy>
<allow-access-from domain="*" to-ports="*"/>
</cross-domain-policy>
但它没有帮助的 crossdomain.xml 文件。
我能做些什么？
您可以在此处查看该应用。
I have a Flex web app (compiled to regular SWF) that tries to connect to a (binary, not XML) socket on its own server. So if the swf is at example.com/app.swf, the socket is example.com:12869
This should be possible, AFAIK, but when I try to connect I get a security error saying that example.com/app.swf cannot access example.com:12869.
Even though it shouldn't be needed, I also have a crossdomain.xml file containing
<cross-domain-policy>
<allow-access-from domain="*" to-ports="*"/>
</cross-domain-policy>
but it doesn't help.
What can I do?

问题是，默认情况下 Flash 会从套接字请求策略，这意味着它会将
您还可以在启动套接字连接之前使用
Security.loadPolicyFile("http://axa3.axastudios.nl/crossdomain.xml")来强制它首先加载您的策略。我不是 100% 确定这是否适用于 Socket 连接，文档（搜索“套接字策略文件”）有点令人困惑。The thing is that by default Flash will request the policy from the socket, meaning it sends
<policy-file-request/>to the Socket - if you have the possibility to add it to your server implementation, you can have a look at how that guy fixed the same sort of problem.You can also use
Security.loadPolicyFile("http://axa3.axastudios.nl/crossdomain.xml")before initiating the socket connection to force it to load your policy first. I'm not 100% sure if this works for Socket connections though, the docs (search for "Socket policy files") are slightly confusing.您可以使用我的 Apache 2 模块 - 它会监听在端口 843 并应答套接字策略请求
You could use my Apache 2 module - it listens at the port 843 and answers socket policy requests
