ajax请求中的laravel TokenMismatchException

2022-01-08 00:00:00 php laravel ajax laravel-4

我正在使用资源组并使用此过滤器来解决 TokenMismatchException 问题:

i'm using resource group and use this filter to resolve TokenMismatchException problem:

Route::filter('csrf', function($route, $request) {
    if (strtoupper($request -> getMethod()) === 'GET') {
        return;
        // get requests are not CSRF protected
    }

    $token = $request -> ajax() ? $request -> header('X-CSRF-Token') : Input::get('_token');

    if (Session::token() != $token) {
        throw new IlluminateSessionTokenMismatchException;
    }
});

我的路线:

Route::group(array('prefix'=> 'admin', 'before' => 'csrf'), function(){
    Route::resource('profile' , 'ProfileController', array('as'=>'profile') );
});

现在.我收到 Ajax 请求错误，例如此代码:

now. i get error to Ajax requests such as this code:

<script type="text/javascript">
    $(document).ready(function() {
       $('#frm').submit(function(e){
           e.preventDefault();
           name         = $('#name').val();
           family       = $('#family').val();
           email        = $('#email').val();
           currPassword = $('#currPassword').val();
           password     = $('#password').val();
           password_confirmation = $('#password_confirmation').val();     

           $.post("{{ route('admin.profile.update', $profile->id) }}",
                { 
                  _method : 'PUT',
                  name                  : name,
                  family                : family,
                  email                 : email,
                  currPassword          : currPassword,
                  password              : password,
                  password_confirmation : password_confirmation  
                },
                function(data)
                {
                    alert(data.errors.name);
                },'json');
                return false;
       });
});
</script>

错误:

{"error":{"type":"Illuminate\Session\TokenMismatchException","message":"","file":"/var/www/alachiq/app/filters.php","line":83}}

我认为我必须在 $.post 中发送 _token.但我无法获得具有 name 属性的 input 标记.我得到这个错误:

i think i'm must be sent _token in $.post. but i can not get input tag with name attribute. iget this error:

TypeError: 'stepUp' called on an object that does not implement interface HTMLInputElement.

推荐答案

Laravel 文档中有一个关于如何做到这一点的提示.这在提出问题时可能不可用，但我想我会用答案更新它.

There is a tip in the Laravel docs on how to do this. This might not have been available at the time of the question, but I thought I would update it with a answer.

http://laravel.com/docs/master/routing#csrf-x-csrf-令牌

我已经测试了文档中的元标记方法并使其正常工作.将以下元标记添加到您的全局模板中

I have tested the meta tag method from the documentation and got it working. Add the following meta tag into your global template

<meta name="csrf-token" content="{{ csrf_token() }}">

添加此 JavaScript，为 jQuery 中的所有 ajax 请求设置默认值.最好在您的应用中包含的 js 文件中.

Add this JavaScript that sets defaults for all ajax request in jQuery. Preferably in a js file that is included across your app.

$.ajaxSetup({
    headers: {
        'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
    }
})

此令牌可以存在于请求标头或表单中.这会将其填充到每个 ajax 请求的请求标头中.

This token can exist in the request header or the form. This populates it into the request header of every ajax request.
