Laravel，尝试通过AJAX将数据传递给控制器​​时出现不匹配的令牌错误

Question

路线：

Route::post('/update', 'PostsController@update');

控制器：

public function update(Request $request) {
    $content = $request;

    return response($content);
}

AJAX：

data = {
    id: postID,
    title: $('[data-post-id='+postID+']').find('.blog_input').val(),
    content: 'testing testing'
};

$.post('/update', data, function(result){
    console.log(result);
});

为此我不断得到错误：

我想提一下title上的输入值来自一个独立的输入，如果有任何线索可能是问题，那么它不在一个完整的<form>内。我如何传递或理顺CSRF令牌差异？

Answer 1

确保您在请求中发送CSRF令牌。

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

<meta name="_token" content="{{ csrf_token() }}">

或者你可以关掉这个中间件，但是不建议这样做。请参阅文档：https://laravel.com/docs/5.3/csrf#csrf-introduction

Answer 2

这对我有用，同时使用@Buglinjo和@Paul的答案：

data = {
    _token: $('meta[name="csrf-token"]').attr('content'),
    id: postID,
    title: $('[data-post-id='+postID+']').find('.blog_input').val(),
    content: 'testing testing'
};

Answer 3

我用它来添加隐藏输入的解决方案

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

通过

通过AJAX访问它

$('#csrf').val()

Answer 4

您应该在data中添加：

data = {
    _token: '{{ csrf_token() }}', //this one
    id: postID,
    title: $('[data-post-id='+postID+']').find('.blog_input').val(),
    content: 'testing testing'
};
