以上代码通过服务器端直接将 crossdomain的内容返回到flex中。 上一篇文章已经介绍过，flex会先请求843这个端口下是否会返回crossdomain的信息因此可以通过部署端口为843的服务在解决flex跨域（8043 安全沙箱的问题）的问题

843端口的服务代码为：

from twisted.internet import reactor from twisted.internet.protocol import Factory, Protocol class PolicySocketProtocol(Protocol): def dataReceived(self, data): self.transport.write("<?xml version=/"1.0/"?><!DOCTYPE cross-domain-policy SYSTEM /"/xml/dtds/cross-domain-policy.dtd/"><cross-domain-policy><site-control permitted-cross-domain-policies=/"master-only/"/><allow-access-from domain=/"\*/" to-ports=/"\*/" /></cross-domain-policy>/0") class PolicyFactory(Factory): def \_\_init\_\_(self): self.protocol = PolicySocketProtocol; if \_\_name\_\_ == '\_\_main\_\_': reactor.listenTCP(843, PolicyFactory(), interface="127.0.0.1") reactor.run()
