SecurityErrorEvent socket as3

flash有着自己的一套安全处理模式，在socket方面，我这样的菜鸟无法理解他的好处：一句话，不怀好意的人如果想用flash写一段带破坏意义的socket客户端（我这里只谈客户端，不谈as3 做 socketserver）程序，你给禁止了，他可以用其他的程序，实际上，这种人也不会用flash去写；你的这些安全的东东实际给真正的使用者带来很多的麻烦。

抱怨的话只能说说，我们无法改变，说说解决方案，

网上一般有以下关于SecurityErrorEvent处理的方式：

1 Security.allowDomain("*");

2 Security.loadPolicyFile("http://oa.oa.com/crossdomain.xml");

3 <policy-file-request/> <cross-domain-policy><allow-access-from domain="*" to-ports="*"/></cross-domain-policy>

4 <paramvalue="all"name="allowNetworking">

第3种是socket服务器用到的，

-------------------------------------------------------

我遇到的问题是——我要做文件上传进度，网上流行的方法是用FileReference的upload，我不想用，因为我有用URLRequest+loader的上传代码。

我的代码是正常向apache+php的服务器发送正常的post表单，代码也完全没有特殊的地方，但是URLRequest不能表现上传的进度，只能表示下载的进度，所以，我想用socket去实现，写好代码之后，出问题了，安全问题，我先试了上面的1 2 4，结果都不行，因为是apache做的服务器端，第三种派不上用场。

看了这篇文章：

http://www.adobe.com/devnet/flashplayer/articles/socket_policy_files.html

我了解到flash可以有一个统一的”socket安全配置服务器“，端口是843，于是我写了一个安全配置服务器，php的，代码如下：

<?php
define('policy_request', "<policy-file-request/>");
define('policy_response', '<cross-domain-policy><allow-access-from domain="*" to-ports="*"/></cross-domain-policy>');
define('policy_response_len', strlen(policy_response)+1);
define('EC', chr(10));$host="0.0.0.0";
$port=843;$socket=socket_create(AF_INET,SOCK_STREAM,0);
if (!socket_set_option($socket, SOL_SOCKET, SO_REUSEADDR, 1)) {echo 'Unable to set option on socket: '. socket_strerror(socket_last_error()) . PHP_EOL;
}socket_bind($socket,$host,$port);
$rett=socket_listen($socket,3);
//socket_set_nonblock($socket);
$clients = array($socket);while(1){$read = $clients;$writes=NULL;$execs=NULL;if(socket_select($read, $writes, $execs, 2) < 1){continue;}if(in_array($socket,$read)) {$clients[] = $newsock = socket_accept($socket);socket_set_nonblock($newsock);$key = array_search($socket,$read);unset($read[$key]);}foreach($read as $read_sock) {$data = trim(socket_read($read_sock, 512, PHP_BINARY_READ));if($data == false) {$key = array_search($read_sock, $clients);unset($clients[$key]);socket_close($read_sock);continue;}if($data==policy_request){socket_write($read_sock,policy_response, policy_response_len);}else socket_write($read_sock,"Bye".EC);socket_close($read_sock);$key = array_search($read_sock, $clients);unset($clients[$key]);}
}socket_close($socket);

当然还遇到其它曲折，就是如何把ByteArray分段发送，见我的上一篇文章。
