Php 使用websocket通信保存数据

我正在创建与WebSocket的“通信”。（谢谢：），通信工作得很好，但当它通过“websocket服务器”时，我试图保存一些日期（？）

我已经创建了socket

ws\u server.php

    <?php
require_once('filegenerator.php');
$filegenerator = new FileGenerator();

$host = '127.0.0.1'; //host
$port = '9000'; //port
$null = NULL; //null var

//Create TCP/IP sream socket
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
//reuseable port
socket_set_option($socket, SOL_SOCKET, SO_REUSEADDR, 1);

//bind socket to specified host
socket_bind($socket, 0, $port);

//listen to port
socket_listen($socket);

//create & add listning socket to the list
$clients = array($socket);

//start endless loop, so that our script doesn't stop
while (true) {
    //manage multipal connections
    $changed = $clients;
    //returns the socket resources in $changed array
    socket_select($changed, $null, $null, 0, 10);

    //check for new socket
    if (in_array($socket, $changed)) {
        $socket_new = socket_accept($socket); //accpet new socket
        $clients[] = $socket_new; //add socket to client array

        $header = socket_read($socket_new, 1024); //read data sent by the socket
        perform_handshaking($header, $socket_new, $host, $port); //perform websocket handshake

        socket_getpeername($socket_new, $ip); //get ip address of connected socket
        $response = mask(json_encode(array('type'=>'system', 'message'=>$ip.' connected'))); //prepare json data
        send_message($response); //notify all users about new connection

        //make room for new socket
        $found_socket = array_search($socket, $changed);
        unset($changed[$found_socket]);
    }

    //loop through all connected sockets
    foreach ($changed as $changed_socket) { 

        //check for any incomming data
        while(socket_recv($changed_socket, $buf, 1024, 0) >= 1)
        {
            $received_text = unmask($buf); //unmask data
            $tst_msg = json_decode($received_text); //json decode 

            if ($tst_msg->type == 'order') {

                filegen( 'String for testing',$filegenerator );

                $items_to_kitchen = $tst_msg->order->items;

                foreach ($items_to_kitchen as $key => $value) {
                    $msg_to_kitchen[$key] = $value;
                }
                $response_text = mask(json_encode(array('order'=>$msg_to_kitchen)));

            } elseif ($tst_msg->type == 'kitchen') {
                $response_text = mask(json_encode(array('type'=>$tst_msg->type,'kitchenstate'=>$tst_msg)));

            }

            send_message($response_text); //send data
            break 2; //exist this loop
        }

        $buf = @socket_read($changed_socket, 1024, PHP_NORMAL_READ);
        if ($buf === false) { // check disconnected client
            // remove client for $clients array
            $found_socket = array_search($changed_socket, $clients);

            send_message($response);
        }
    }
}
// close the listening socket
socket_close($sock);

function send_message($msg)

}


//Unmask incoming framed message
function unmask($text) {
    $length = ord($text[1]) & 127;
    if($length == 126) {
        $masks = substr($text, 4, 4);
        $data = substr($text, 8);

        $data = substr($text, 6);

    $text = "";
    for ($i = 0; $i < strlen($data); ++$i) {

    $length = strlen($text);

    if($length <= 125)
        $header = pack('CC', $b1, $length);
    elseif($length > 125 && $length < 65536)
        $header = pack('CCn', $b1, 126, $length);
    elseif($length >= 65536)
        $header = pack('CCNN', $b1, 127, $length);
    return $header.$text;
}

//handshake new client.
function perform_handshaking($receved_header,$client_conn, $host, $port)
{
    $headers = array();
    $lines = preg_split("/\r\n/", $receved_header);
    foreach($lines as $line)
    {
        $line = chop($line);
        if(preg_match('/\A(\S+): (.*)\z/', $line, $matches))
        {
            $headers[$matches[1]] = $matches[2];
        }
    }

    $secKey = $headers['Sec-WebSocket-Key'];
    $secAccept = base64_encode(pack('H*', sha1($secKey . '258EAFA5-E914-47DA-95CA-C5AB0DC85B11')));

<?php

class FileGenerator{
private $_filename;
private $_data;

public function write($str_filename,$str_data){
    $this->_filename = $str_filename;
    $this->_data = $str_data;

    $this->_checkPermission();

    $this->_checkData();

    $handle = fopen($str_filename,'w');

    fwrite($handle, $str_data."\r\n");
    fclose($handle);
}

public function test(){
    echo "This string outputs in console";
    // php -q ws_server.php
}

public function read($str_filename){
    $this->_filename = $str_filename;
    echo $this->_filename;
    $this->_checkExists();
    $handle = fopen($str_filename, 'r');
    return file_get_contents($str_filename);
}

private function _checkPermission(){
    if ( !is_writable($this->_filename)) {
        die('Change your CHMOD permissions to:'.$this->_filename);
    }
}

private function _checkData(){
    if (strlen($this->_data) < 1) {
        die('You must have more than one character for data');
    }
}

private function _checkExists(){
    if (!file_exists($this->_filename)) {
        die('The File does not exis');
    }
}
}

function filegen( $str,$filegenerator ){
$filegenerator->test();
$filegenerator->write('test.json',$str);
}

?>

当我在

ws\u server.php

的第58行调用函数filegen（）时

filegen( 'String for testing',$filegenerator );

在权限栏中，检查程序die（）。但是

该文件是可写、完全访问的（用于测试目的）

它存在

有趣的是，当我创建另一个文件来测试FileGenerator类时，它工作得非常好，但不是从

ws\u server.php

文件创建的

我在windows上使用xampp 控制台运行：php-qd:\xampp\htdocs\xxx\includes\ws\u server.php

我试着简单地说

$handle = fopen($str_filename,'w');
fwrite($handle, $str_data."\r\n");
fclose($handle);

但同样的问题也发生了。有趣的是，如果我回显，我可以得到$handle#id，回显fwrite（）可以返回字符数，但文件不会更改

谁能帮帮我，描述一下我做错了什么！谢谢

我认为这是路径问题或文件所有权问题

请尝试

$filegenerator->write（\uu DIR\uu.'/test.json，$str）

以确保它尝试在文件所在的目录中写入test.json

检查文件系统上的文件所有者是谁。Web服务器通常有自己的用户（例如www数据），这可能与您自己的登录用户冲突。您可能必须

chown

第二句话是正确的，权限是可以的，我检查过了，但是谢谢你的第一句话，它很有效！在谷歌上搜索了几个小时后，现在你的建议就完美了。我将在将来练习这一步，以关注路径。谢谢你能解释一下为什么我们的董事不为我工作吗？所有文件都在同一个目录中。如果不添加

\uuuu DIR\uuuu>或绝对路径，它将使用运行PHP的路径。您说过您使用了
php-qd:\xampp\htdocs\xxx\includes\ws\u server.php
。这取决于运行此命令的位置。例如，如果您首先
cd
到
D:\Users\YourName
，然后
运行php-qd:\xampp\htdocs\xxx\includes\ws\u server.php
，它将尝试在
D:\Users\YourName\test.json
中写入test.json。但是如果您先将cd刻录到
D:\
，然后运行
php-qd:\xampp\htdocs\xxx\includes\ws\u server.php
，它将尝试写入
D:\test.json
。所以，这就是为什么您必须始终指定文件路径的原因。
