Laravel 5-CSRF禁用方法和修改为cookie存储

CSRF攻击和漏洞的参考文章

http://www.cnblogs.com/hyddd/archive/2009/04/09/1432744.html

Laravel默认是开启了CSRF功能。

关闭此功能有两种方法

方法一

打开文件:app\Http\Kernel.php

'App\Http\Middleware\VerifyCsrfToken'//注释掉

方法二

打开文件:app\Http\Middleware\VerifyCsrfToken.php修改为:

<?php namespace App\Http\Middleware;

use Closure;
use Illuminate\Foundation\Http\Middleware\VerifyCsrfToken as BaseVerifier;

class VerifyCsrfToken extends BaseVerifier {

    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        // 使用CSRF
        //return parent::handle($request, $next);
        // 禁用CSRF
        return $next($request);
    }

}

CSRF的使用有两种方法:

第一种

在HTML的代码中加入:

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

第二种

使用cookie方式。

使用cookie方式的CSRF,可以不用在每个页面都加入这个input的hidden标签。

使用cookie方式,需要把app\Http\Middleware\VerifyCsrfToken.php修改为:

<?php namespace App\Http\Middleware;

use Closure;
use Illuminate\Foundation\Http\Middleware\VerifyCsrfToken as BaseVerifier;

class VerifyCsrfToken extends BaseVerifier {

    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        return parent::addCookieToResponse($request, $next($request));
    }

}

只对GET的方式提交使用CSRF,对POST方式提交表单禁用CSRF

对指定的表单[提交方式]使用CSRF,如:

<?php namespace App\Http\Middleware;

use Closure;
use Illuminate\Foundation\Http\Middleware\VerifyCsrfToken as BaseVerifier;

class VerifyCsrfToken extends BaseVerifier {

    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        // Add this:
        if($request->method() == 'POST')
        {
            return $next($request);
        }
        
        if ($request->method() == 'GET' || $this->tokensMatch($request))
        {
            return $next($request);
        }
        throw new TokenMismatchException;
    }

}

修改CSRF的cookie名称方法

要修改这个名称值,可以到打开这个文件:vendor\laravel\framework\src\Illuminate\Foundation\Http\Middleware\VerifyCsrfToken.php 找到”XSRF-TOKEN“,修改

/**
     * Add the CSRF token to the response cookies.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Symfony\Component\HttpFoundation\Response  $response
     * @return \Symfony\Component\HttpFoundation\Response
     */
    protected function addCookieToResponse($request, $response)
    {
        $config = config('session');

        $response->headers->setCookie(
            new Cookie(
                'XSRF-TOKEN', $request->session()->token(), $this->availableAt(60 * $config['lifetime']),
                $config['path'], $config['domain'], $config['secure'], false, false, $config['same_site'] ?? null
            )
        );

        return $response;
    }

也可以在app\Http\Middleware\VerifyCsrfToken.php文件中,重写addCookieToResponse()方法做到
