针对内容比较长出错,修改后的解码函数 和 加码函数 原文请看上一篇 http://yixun.yxsss.com/yw3104.html

function uncode($str,$key){
$mask = array();
$data = '';
$msg = unpack('H*',$str);
$head = substr($msg[1],0,2);
if ($head == '81' && !isset($this->slen[$key])) {
$len=substr($msg[1],2,2);
$len=hexdec($len);
if(substr($msg[1],2,2)=='fe'){
$len=substr($msg[1],4,4);
$len=hexdec($len);
$msg[1]=substr($msg[1],4);
}else if(substr($msg[1],2,2)=='ff'){
$len=substr($msg[1],4,16);
$len=hexdec($len);
$msg[1]=substr($msg[1],16);
}
$mask[] = hexdec(substr($msg[1],4,2));
$mask[] = hexdec(substr($msg[1],6,2));
$mask[] = hexdec(substr($msg[1],8,2));
$mask[] = hexdec(substr($msg[1],10,2));
$s = 12;
$n=0;
}else if($this->slen[$key] > 0){
$len=$this->slen[$key];
$mask=$this->ar[$key];
$n=$this->n[$key];
$s = 0;
} $e = strlen($msg[1])-2;
for ($i=$s; $i<= $e; $i+= 2) {
$data .= chr($mask[$n%4]^hexdec(substr($msg[1],$i,2)));
$n++;
}
$dlen=strlen($data); if($len > 255 && $len > $dlen+intval($this->sjen[$key])){
$this->ar[$key]=$mask;
$this->slen[$key]=$len;
$this->sjen[$key]=$dlen+intval($this->sjen[$key]);
$this->sda[$key]=$this->sda[$key].$data;
$this->n[$key]=$n;
return false;
}else{
unset($this->ar[$key],$this->slen[$key],$this->sjen[$key],$this->n[$key]);
$data=$this->sda[$key].$data;
unset($this->sda[$key]);
return $data;
} } function code($msg){
$frame = array();
$frame[0] = '81';
$len = strlen($msg);
if($len < 126){
$frame[1] = $len<16?'0'.dechex($len):dechex($len);
}else if($len < 65025){
$s=dechex($len);
$frame[1]='7e'.str_repeat('0',4-strlen($s)).$s;
}else{
$s=dechex($len);
$frame[1]='7f'.str_repeat('0',16-strlen($s)).$s;
}
$frame[2] = $this->ord_hex($msg);
$data = implode('',$frame);
return pack("H*", $data);
}

其中主函数run 里面的接收修改为

do{
$l=socket_recv($sock,$buf,1000,0);
$len+=$l;
$buffer.=$buf;
}while($l==1000);

服务器端代码:

var fs = require('fs')
, http = require('http')
, socketio = require('socket.io');var server = http.createServer(function(req, res) {
res.writeHead(200, { 'Content-type': 'text/html'});
res.end(fs.readFileSync(__dirname + '/index.html'));
}).listen(8080, function() {
console.log('Listening at: http://localhost:8080');
});var ids=[];
var io=socketio.listen(server);
io.on('connection', function (socket) {
ids.push(socket.id);
socket.on('key', function (msg) {
console.log('Message Received: ', msg);
console.log('sockid:'+socket.id);
console.log(ids); io.sockets.socket(ids[0]).emit('key',msg);//向指定的用户发信息
//socket.broadcast.emit('key', msg); //公告
//socket.emit('key', msg); //发给自己
});
socket.on('disconnect',function(){
console.log('关闭'+socket.id);
});
});

客服端:

最近弄html5最新功能WebSocket 网上找了很多资料 都是相互抄袭 而且用不了,经过2天的折腾 终于好了,不过还有昵称是中文名的时候会自动断了的问题 估计是转码的问题。
