Question

我遇到3个会话变量的问题，我有一个名为 chat.php 的文件，这是：

class Chat implements MessageComponentInterface {
protected $clients;
protected $data_clients;
protected $target = "xxxxx"; //conversation target number/JID

public function __construct() {
    $this->clients = new \SplObjectStorage;
    $this->data_clients = new \SplObjectStorage;

    session_start();
    echo 'begin';
    $_SESSION["running"] = time();
    $_SESSION["inbound"] = array();
    $_SESSION["outbound"] = array();
    echo 'end';

    $this->send_message('hello');

    $this->Listen(true);

}



public function onError(ConnectionInterface $conn, \Exception $e) {
    echo "An error has occurred: {$e->getMessage()}\n";
    $conn->close();
}

public function Listen($initial){
   $band=false;

    $options = array(
        CURLOPT_HEADER => false,
        CURLOPT_TIMEOUT => 40000
    );

    $params=['initial'=>$initial, 'target'=>$this->target,'method'=>'prueba'];
    $defaults = array(
        CURLOPT_URL => 'localhost/socket/src/myApp/script2.php',
        CURLOPT_POST => true,
        CURLOPT_POSTFIELDS => http_build_query($params),
    );
    $ch = curl_init();
    curl_setopt_array($ch, ($options + $defaults));
    curl_exec($ch);

    if(curl_errno($ch)){
        $band=true;
    }
    curl_close($ch);

    if(!$band)
        $this->Listen(false);
}//fin Listen


public function send_message($mensaje){

    $band=false;
    $options = array(
        CURLOPT_HEADER => false,
    );

    $params=['method'=>'sendMessage','target'=>$this->target,'message'=>$mensaje];
    $defaults = array(
        CURLOPT_URL => 'localhost/socket/src/myApp/ajax2.php',
        CURLOPT_POST => true,
        CURLOPT_POSTFIELDS => http_build_query($params),
    );
    $ch = curl_init();
    curl_setopt_array($ch, ($options + $defaults));
    curl_exec($ch);
    curl_close($ch);


}//fin de enviar mensaje
}

所以，我 $ this-＆gt; send_message（＆＃39; hello＆＃39;）来自构造函数调用一个名为ajax2的脚本，但后来我遇到了这个错误：

Notice: Undefined index: outbound in C:\xampp\htdocs\socket\src\myApp\ajax2.php on line 16
envia
Notice: Undefined index: running in C:\xampp\htdocs\socket\src\myApp\socket2.php on line 15

ajax2的内容是：

    <?php
session_start();

$method = $_POST["method"];

switch ($method) {
    case "sendMessage":
        $target = $_POST["target"];
        $message = $_POST["message"];
        $outbound = $_SESSION["outbound"];
        $outbound[] = array("target" => $target, "body" => $message);
        $_SESSION["outbound"] = $outbound;
        break;
    case "pollMessages":
        $inbound = @$_SESSION["inbound"];
        $_SESSION["inbound"] = array();
        $profilepic = @$_SESSION["profilepic"];
        $ret = new JSONResponse();
        if ($profilepic != null && $profilepic != "") {
            $ret->profilepic = $profilepic;
        }
        $_SESSION["profilepic"] = "";
        if (count($inbound) > 0) {
            foreach ($inbound as $message) {
                $ret->messages[] = $message;
            }
        }
        echo json_encode($ret);
        break;
}

所以，问题在于会话变量，我不知道我做错了什么，我已经做了 session_start 。如果你看到，我在构造中创建了它们，然后在ajax2中使用它们。谢谢！

Answer 1

它不起作用，因为你试图访问会话变量$ _SESSION [＆＃34; outbound＆＃34;]，$ _ SESSION [＆＃34; inbound＆＃34;]，$ _ SESSION [＆＃34; profilepic＆＃34 ;] ajax2.php中完全不同的会话

导致session.start（）在chat.php中创建会话;与session_start（）在ajax2.php中创建的会话不同;因为您正在通过CURL访问ajax2.php，这会在ajax2.php中创建一个新的部分，这将与chat.php中的会话不同

带有Session变量的未定义索引
