会话不适用于ajaxRequest [如何使用会话变量计算ajax-request]

Question

I have the following PHP code which counts every access to the page. If I call the side direct it counts certain. If I make a Ajax call it starts always again with 1.

<?php
session_start();    
header('Access-Control-Allow-Origin: *');

        if (!isset($_SESSION['zaehler'])) {
          $_SESSION['zaehler'] = 1;
        } else {
          $_SESSION['zaehler']++;
        }
echo  $_SESSION['zaehler'];


?>

I understand that an ajax call is the same like an direct call by reading this: Do AJAX requests retain PHP Session info? How can I count each ajaxCall as long as the side is open?

I'm doing a simple jquery ajaxCall:

    $.get( "http://www.huntinggrounds.de/aa.php", function( data ) {
         console.log( "dataResponse: ", data );
    }) .fail(function(jqXHR, textStatus ) {
        console.log( "error",textStatus);
       })
       .always(function() {
        console.log( "finished" );
       });

I made test-files, testfile.html, just a black screen. Click on desktop and see the counter in your console the php-file is here.

After testing your pages, your problem is related to your domain.

http://www.huntinggrounds.de/aa.html is working fine, not http://huntinggrounds.de/aa.html

For security reasons, cookie is per-domain specific. Cookie set by PHP on http://huntinggrounds.de/aa.html will not work on http://www.huntinggrounds.de/aa.html depending of your configuration.

To by pass this problem, don't set full URL in your ajax. Preferer relative URI.

$.get( "/collect?"+setParameter(defs),
 function( data ) {
      try {
             console.log("New count is : ",data);
          } catch(e) {
             // if there is no response
             console.log( "No answer : ", data);
         }
  })
