问题描述

从文件切换到数据库会话时，我的 $request->input(_token) 与 $request->session()->toke() 不匹配.

My $request->input(_token) is a mismatch of $request->session()->toke() when switching from file to database sessions.

这会导致 CSRF TokenMismatchException.当从数据库切换回文件会话驱动程序时，不会发生不匹配.

This is causing a CSRF TokenMismatchException. When switching back from database to file sessons driver the mismatch does not occur.

有谁知道我为什么会出现这种不匹配以及如何解决它?:)我做了什么:

<小时>使用 Laravel 5.0
PHP 5.6.30

php artisan session:table : 创建 Laravel 会话表作曲家转储自动加载php工匠配置:清除php arisan 配置:缓存

php artisan session:table : Created Laravel session table composer dump-autoload php artisan config:clear php arisan config:cache

我的 session.php 配置如下所示:

My session.php config looks like this:

return [

    'driver' => 'database',
    'lifetime' => 120,
    'expire_on_close' => false,
    'encrypt' => false,
    'files' => storage_path().'/framework/sessions',
    'connection' => null,
    'table' => 'laravel_session',
    'lottery' => [2, 100],
    'cookie' => 'laravel_session',
    'path' => '/',
    'domain' => null,
    'secure' => false,

];

VerifyCsrfToken IlluminateFoundationMiddleware

protected function tokensMatch($request)
{
    $tok =  $request->input('_token') ; //4ExGXl9mRM75d7brfQhgIWcQzsSVjnUHDoDcKJxp
    $tokhead  = $request->header('X-CSRF-TOKEN'); 
    $sessToken = $request->session()->token();//57DLb3uTs8brVPKpBxor14Hg0ZvQPpYW3flktP86

    $token = $request->input('_token') ?: $request->header('X-CSRF-TOKEN');

    if ( ! $token && $header = $request->header('X-XSRF-TOKEN'))
    {
        $token = $this->encrypter->decrypt($header);
    }

    return StringUtils::equals($request->session()->token(), $token);

切换到数据库sesseio驱动后，数据库表填充数据:

Database table is populated with data after switching to database sesseio driver:

SELECT id, payload, last_activity, user_id FROM kartserver_2.laravel_session;

我在 html 中生成 csrf_tokens

I am generating csrf_tokens in html

<input type="hidden" name="_token" id="_token" value="{!! csrf_token() !!}">

推荐答案

如果你在使用 Laravel 5.4* 并且碰巧遇到了这个问题，这就是你需要做的事情

If you are using Laravel 5.4* and you happen to stumble upon this problem, here is what you need to do

1- 更新您的 .env 文件

1- Update your .env file

# file = .env in your project root

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=testdb
DB_USERNAME=db_user
DB_PASSWORD=secret_pass

SESSION_DRIVER=database

注意此处的 DB_CONNECTION 设置，您将在下一步中使用.

Note the DB_CONNECTION setting here that you will need in next step.

2- 更新 config/session.php 文件连接参数应该包含您在 .env 文件中用于 DB_CONNECTION 的字符串

2- update config/session.php file Where connection param should hold the string you used for DB_CONNECTION in .env file

# file = config/session.php

'driver' => env('SESSION_DRIVER', 'database'),
'connection' => 'mysql', // this is from DB_CONNECTION in .env file 

3- 生成会话表

php artisan session:table
// run the migration !!! very very important
php artisan migrate

4- 如果出于某种原因您决定手动创建表而不使用迁移，请使用此 SQL.这是非常重要的一步，一个错误的表会导致各种问题.主要是不要犯错手动创建表，id列和往常一样bigint，session表不一样.

4- if for some reason you decided to create the table manually without using migration , use this SQL. This is very important step, a wrong table will result in all kinds of problems. Primarily do not make the mistake of creating a table manually with id column as bigint as usual, session table is different.

DROP TABLE IF EXISTS `sessions`;
create table sessions
(
  id varchar(255) not null,
  user_id int(10) unsigned null,
  ip_address varchar(45) null,
  user_agent text null,
  payload text not null,
  last_activity int not null,
  constraint sessions_id_unique
  unique (id)
)

这应该可以解决将db设置为会话保存路径后的令牌不匹配异常.

That should solve the token mismatch exception after setting db as session save path.
