Question

我试图通过ajax将数据提交到数据库。提交文章页面没有ajax工作正常。我已添加console.log()只是为了查看是否有任何问题，但我收到了此错误：

POST http://localhost/laravel-5/public/articles/create 500（内部服务器错误）

我的代码出了什么问题？是javascript还是控制器？

编辑：我在laravel.log

中收到此消息

exception＆＃39; Illuminate \ Session \ TokenMismatchException＆＃39;在C：\ xampp \ htdocs \ laravel-5 \ vendor \ laravel \ framework \ src \ Illuminate \ Foundation \ Http \ Middleware \ VerifyCsrfToken.php：53

路线

Route::resource('articles', 'ArticlesController');

控制器

public function store(Requests\ArticleRequest $request)
    {

        $article = new Article($request->all());
        Auth::user()->articles()->save($article);

        $response = array(
            'status' => 'success',
            'msg' => 'Article has been posted.',
        );
        return \Response::json($response);
    }

的jQuery

$(document).ready(function() {
    $('#frm').on('submit', function (e) {
        e.preventDefault();
        var title = $('#title').val();
        var body = $('#body').val();
        var published_at = $('#published_at').val();
        $.ajax({
            type: "POST",
            url: 'http://localhost/laravel-5/public/articles/create',
            dataType: 'JSON',
            data: {title: title, body: body, published_at: published_at},
            success: function( data ) {
                $("#ajaxResponse").append(data.msg);
                console.log(data);
            }
        });
    });

Answer 1

当您通过POST向资源控制器发出请求时，它会自动调用存储方法：

Verb    Path        Action  Route Name
----------------------------------
POST    /articles   store   articles.store

所以，你只需要将ajax url更改为：

$.ajax({
        type: "POST",
        url: 'http://localhost/laravel-5/public/articles',

当您需要发送会话令牌时，您可以添加一个全局元标记，例如这是您的网站：

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

然后，只需通过ajax的标题添加令牌：

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

如果您使用的是Form::open()函数（LaravelCollective），则会添加一个隐藏的输入，并将该标记作为值_token的值。因此，您可以删除元标记并编辑您的ajax标题，如下所示：

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

Answer 2

这就是我在C：\ xampp \ htdocs \ laravel-5 \ vendor \ laravel \ framework \ src \ Illuminate \ Foundation \ Htt p \ Middleware \ VerifyCsrfToken.php中得到异常'Illuminate \ Session \ TokenMismatchException'：53

你正在使用Laravel的CSRF保护。

http://laravel.com/docs/5.1/routing#csrf-protection

您需要传递隐藏的_token字段的值。这可以通过在应用程序的JS中执行此操作，在所有jQuery启动的AJAX请求上自动完成：

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

或者，您可以在每个AJAX调用中手动获取并传递_token隐藏字段的值。

Answer 4

您可以将您的URL添加到VerifyCsrfToken.php中间件。这些网址将从CSRF验证中排除：

protected $except = [ "your url", "your url/abc" ];

Answer 5

如果您正在寻找确定的答案，那么它是：如果您在代码中缺少csrf_token（），则会发生此错误这是我做的，

<h6>ITEMS  ORDERED:<a href="#" id="{{$post->identifier}}" onclick="getcart(this.id)">CLICK HERE</a></h6>
<input type="hidden" id="token" value="{{ csrf_token() }}">

现在使用Ajax

<script type="text/javascript">
function getcart(val) {
  var alpha=val;
var token=document.getElementById('token').value;

$.ajax({
 type:'post',
 url:'/private/getcart',
 data:{'alpha':alpha,'_token': token},//this _token should be as it is 
 success:function (result) {
alert(result);
 }

});


}

</script>

在我的laravel控制器

中

public function getcart(Request $req)
{
  return response ("its");
}
