getJSON和OAuth令牌

Question

I'm working on a script that uses jQuery (getJSON) to pullback values from a PHP page. 我正在使用jQuery（getJSON）从PHP页面提取值的脚本。 The PHP page correctly displays the encoded object with the correct keys and values, with the values being retrieved from the $_SESSION variable. PHP页面正确显示具有正确键和值的编码对象，并从$_SESSION变量中检索值。 However when the javascript attempts to access this page, the object is retrieved, but only the keys are intact with the values being replaced with null . 但是，当javascript尝试访问此页面时，将检索该对象，但只有键完整无缺，而值将替换为null 。 The values that are returning null are retrieved from the $_SESSION , whereas any values that are manually added are correctly returning. 从$_SESSION检索返回null的值，而正确添加任何手动添加的值。 Is this something that can be avoided/fixed? 这是可以避免/解决的问题吗？ Would it make more sense to store the access tokens in cookies rather than sessions? 将访问令牌存储在cookie中而不是会话中是否更有意义？

Code examples: 代码示例：

<?php
  session_start();

  $token = $_SESSION['token'] -> access_token;

  $information = [
     "media_token" => $token,
     "test" => "testing"
     ]; 

  print json_encode($information); //when page is directly accessed, 
                                   //returns correct information
?>

Javascript: Javascript：

$.getJSON('oauth.php', function (data){
            console.log(data); // media_token: null
                               // test: testing
    });

Try this code it will help you 试试这个代码将对您有帮助

<html>

oauth.php file oauth.php文件

 session_start();
  $_SESSION['token']="Hello1212";
  $token = $_SESSION['token'];// -> access_token;

  $information = array(
    "media_token" => $token,
    "test" => "testing"
);

  print json_encode($information); //when page is directly accessed, 
                                   //returns correct information

Answer 2

Turns out the issue was that I was accessing the page that contained the JS using a non-www page, whereas adding www fixed the problem. 原来的问题是我正在使用非www页面访问包含JS的页面，而添加www解决了该问题。 Not sure why but clearly this changed if the page could access the $_SESSION or not. 不知道为什么，但是很明显，如果页面可以访问$ _SESSION，则此更改。 If anyone could explain why this is the case that'd be great, cheers. 如果有人能解释为什么会这样，那会很高兴。
