Codeigniter 3 - 从外部代码访问会话安装 [英] Codeigniter 3 - Access Session from Outside Codeigniter Installation

问题描述

我似乎无法从我的codeigniter应用程序传递的会话数据回到我的包含文件夹中的脚本。根据我在其他答案上阅读的内容，我需要设置 session_id（）才能重新加入一个会话 session_start（）。

I can't seem to get session data passed from my codeigniter application back to a script in my includes folder. From what I've read on other answers, I need to set my session_id() to be able to rejoin a session with session_start().

ROOT /
     .. /application
     .. /system
     .. /includes
        .. /Events.php <- I need access from here

理论上代码下面应该工作，至少根据其他答案，因为新的CI会话库传递到本地会话。

Theoretically the code below should work, at least according to other answers, because the new CI session library passes on to native sessions.

session_id($_COOKIE['ci_session']);
session_start();
var_dump($_SESSION); // returns null

我误解了会话吗？

推荐答案

来自@ wolfgang1983的原始答案 Ben Swinburne 在这里结合了答案：from Atiqur Ra​​hman Sumon

The original answer from @wolfgang1983 Ben Swinburne combinded with an answer here: from Atiqur Rahman Sumon

您可以将 index.php 但是，您需要更改 $ system_path 和 $ application_folder 变量以匹配您的相对位置。如果你想完全改变你的整个应用程序的路径，但我不想，所以我只是把 index.php 文件复制到我需要的目录包含代码符号。

You can include the index.php from any directory, however, you need to change the $system_path and $application_folder variables to match your relative location. Well that's great if you want to completely change your whole application's paths, but I didn't want to, so I just copied the index.php file into the directory I needed to include codeigniter with.

ROOT /
     .. /application
     .. /system
     .. /includes
        .. /Events.php <- I need access from here
        .. /index.php <- Copied CI index with new paths
     .. /index.php

在 /includes/index.php ：

//$system_path = 'system';
$system_path = '../system';

//$application_folder = 'application';
$application_folder = '../application';

现在你可以在你的文件中加入codeigniter了：

Now you can include codeigniter in your file with the:

<?php
    ob_start();
    include('index.php');
    ob_end_clean();
    $CI =& get_instance();
    $CI->load->library('session'); //if it's not autoloaded in your CI setup
    echo $CI->session->userdata('name');
?>

如果您现在刷新页面，则会加载默认控制器。 / strong>

If you refresh your page now, you would end up with the default controller loaded.

因此，从Atiqur Ra​​hman Sumon的回答，我们可以在加载之前定义一个常量，告诉默认控制器我们要跳过正常的callstack。

So taking from Atiqur Rahman Sumon's answer, we can define a constant before load to tell the default controller we want to skip it's normal callstack.

ob_start();
define("REQUEST", "external"); <--
include('index.php');
ob_end_clean();

在 default_controller.php ：

function index()
{
    if (REQUEST == "external") {
        return;
    } 

    //other code for normal requests.
}
