PHP $_SESSION 跨子域

Question

好的，所以我有 example.com 然后我使用 Javascript 运行 XHR 请求到 api.example.com 以前我有 api.example.com 作为 example.com/api 但我想将其移至子域并且登录工作正常，直到我将其移至 api.example.com

我正在测试登录脚本并尝试保持会话有效，但每次运行时都会清除 $_SESSION

db_connect.php

include_once("config.php");
ob_start();
session_start();
$db = new mysqli(DB_HOST, DB_USER, DB_PASS, DB_NAME);

auth.php

<?php
require($_SERVER['DOCUMENT_ROOT'].'/db_connect.php');

if (!$db) {
    die('Could not connect: ' . mysql_error());
}
$method = $_SERVER['REQUEST_METHOD'];

if ( isset($_GET['id']) ){
    $id = $_GET['id'];
} else {
    $id = 'all';
}

switch (strtoupper($method)) {
    case "GET":
        if ($_SESSION['auth']) {
            $check = true;
        } else {
            $check = false;
        }
        $arr = json_encode(array('result'=>$check));
        echo $arr;
    break;
    default:
        echo "Streets closed pizza boy!";
}

signin.php

<?php
require($_SERVER['DOCUMENT_ROOT'].'/db_connect.php');

if (!$db) {
    die('Could not connect: ' . mysql_error());
}
$method = $_SERVER['REQUEST_METHOD'];

if ( isset($_GET['id']) ){
    $id = $_GET['id'];
} else {
    $id = 'all';
}

switch (strtoupper($method)) {

    case "POST":
        $postdata = json_decode(file_get_contents("php://input"));
        $src = (array)$postdata->user;
        $password = hash( 'sha512', $src['password']);

        $q = $db->query("SELECT *
            FROM users u
            WHERE u.email = '".$src['email']."'
            AND u.password = '".$password."'");

            if($q->num_rows > 0){
                $check = true;
                $_SESSION['auth'] = 1;

                $maps = array();
                while($row = mysqli_fetch_array($q)) {
                    $product = array(
                        'auth' => 1,
                        'id' => $row['id'],
                        'name' => $row['name'],
                        'email' => $row['email'],
                        'access' => $row['access']
                    );
                    array_push($maps, $product);
                }

                //$_SESSION['company_id'] = $product['company_id'];
            }else{
                $check = false;
            }

            $_SESSION['id'] = $product['id'];   
            $_SESSION['email'] = $product['email']; 

            setcookie("username", $productx§['email'], time()+(84600*30));

            $arr = json_encode(array('result'=>$check, 'user'=>$maps));
            echo $arr;
    break;

    default:
        echo "Your favorite color is neither red, blue, or green!";
}

我试过将db_connect.php设置为

<?php
include_once("config.php");
ob_start();
session_set_cookie_params(0, '/', '.example.com');
session_start();
$db = new mysqli(DB_HOST, DB_USER, DB_PASS, DB_NAME);

但这没有任何作用，会话变量也丢失了。

PHP 文件也通过 AJAX 调用。

是否所有页面是否 angularjs DOM 都应该连接到数据库？

Answer 1

尝试设置会话名称：

$session_name = session_name("my_session");

然后，将会话 cookie 设置为跨越所有子域：

session_set_cookie_params(0, "/", ".example.com");

然后执行 session_start() - 它现在应该可以工作了。

Answer 2

要使用跨子域会话，您必须在所有子域项目中使用以下代码：

session_name('SessionName');
session_set_cookie_params(
    1800,
    ini_get('session.cookie_path'),
    '.example.com'
);
session_start();

重要：仅当所有子域都在一台服务器上时它才有效（因为会话存储在一个 tmp 目录中）。如果你想在不同的服务器上使用类似的会话，使用SAN存储或者将会话存储在memcached等

ini_set('session.save_handler', 'memcache');
ini_set('session.save_path', 'tcp://122.122.122.122:11211');

session_name('SessionName');
session_set_cookie_params(
    1800,
    ini_get('session.cookie_path'),
    '.exmaple.com'
);
session_start();

Answer 3

.htaccess 在 api.example.com

# CORS Headers (add this)
<ifModule mod_headers.c>
    Header add Access-Control-Allow-Origin "http://example.com"
      ## Post the domain that will be doing the XHR requests
    Header add Access-Control-Allow-Credentials: "true"
    Header add Access-Control-Allow-Headers "origin, x-requested-with, content-type"
    Header add Access-Control-Allow-Methods "PUT, GET, POST, DELETE, OPTIONS"
</ifModule>
<Limit GET POST PUT DELETE>
    Allow from all
</Limit>

example.com

Post您主网站header中的以下内容

ini_set('session.cookie_domain', '.example.com' );
session_start();

XHR 请求

现在我们需要 post 从 example.com 到 api.example.com 我' m 使用 AngularJS 和这个

$http({
    method: 'GET',
    url: '//api.example.com/auth/',
    xhrFields: {
        withCredentials: true
    },
    crossDomain: true
}).success....

同时更改您的配置以允许使用凭据发送

.config(function ($routeProvider, $httpProvider) {
    $httpProvider.defaults.withCredentials = true;
    //rest of route code

Answer 4

这对我有用：

ini_set('session.cookie_domain', substr($_SERVER['SERVER_NAME'],strpos($_SERVER['SERVER_NAME'],"."),100));
session_start();

起初，它不起作用，我不得不删除所有 cookie，最后它按预期工作了。
