flash as3 socket安全服務網關（socket policy file server）
關鍵字：javascript
SecurityErrorEvent socket as3php
flash有着本身的一套安全處理模式，在socket方面，我這樣的菜鳥沒法理解他的好處：一句話，不懷好意的人若是想用flash寫一段帶破壞意義的socket客戶端（我這裏只談客戶端，不談as3 作 socketserver）程序，你給禁止了，他能夠用其餘的程序，實際上，這種人也不會用flash去寫；你的這些安全的東東實際給真正的使用者帶來不少的麻煩。html
抱怨的話只能說說，咱們沒法改變，說說解決方案，java
網上通常有如下關於SecurityErrorEvent處理的方式：node
1 Security.allowDomain("*");apache
2 Security.loadPolicyFile("http://oa.oa.com/crossdomain.xml");安全
3 <policy-file-request/> <cross-domain-policy><allow-access-from domain="*" to-ports="*"/></cross-domain-policy>服務器
4 <param value="all" name="allowNetworking">app
第3種是socket服務器用到的，dom
-------------------------------------------------------
我遇到的問題是——我要作文件上傳進度，網上流行的方法是用FileReference的upload，我不想用，由於我有用URLRequest+loader的上傳代碼。
個人代碼是正常向apache+php的服務器發送正常的post表單，代碼也徹底沒有特殊的地方，可是URLRequest不能表現上傳的進度，只能表示下載的進度，因此，我想用socket去實現，寫好代碼以後，出問題了，安全問題，我先試了上面的1 2 4，結果都不行，由於是apache作的服務器端，第三種派不上用場。
看了這篇文章：
http://www.adobe.com/devnet/flashplayer/articles/socket_policy_files.html
我瞭解到flash能夠有一個統一的」socket安全配置服務器「，端口是843，因而我寫了一個安全配置服務器，php的，代碼以下：
<?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);
固然還遇到其它曲折，就是如何把ByteArray分段發送，見個人上一篇文章。
