500（内部服务器错误）Laravel删除方法

时间：2018-09-19 09:42:34

标签： ajax laravel

我试图在laravel中使用Ajax删除，但它向我显示了类似500（内部服务器错误）的错误，我知道它是令牌错误，但是我传递令牌也仍然遇到相同的错误。没有ajax，我可以删除一条记录。

enter image description here

路线： 

Route::get('users/delete/{id}','UserController@destroy');

HTML 

    <button type="button" class="btn btn-sm btn-outline-danger js-sweetalert"  data-token="{{ csrf_token() }}" data-id="{{$obj->id}}" title="Delete" data-type="confirm"><i class="fa fa-trash-o"></i></button>
    <script>
    $(function () {
    $('.js-sweetalert').on('click', function (e) {
        e.preventDefault();
        var type = $(this).data('type');
        var id = $(this).data('id');
        var token = $(this).data("token");
        var url = $(this).attr("data-link");
        if (type === 'confirm') {
            showConfirmMessage(id,token,url);
        }
      });
    }); 
    function showConfirmMessage(id,token,url) {
    swal({
        title: "Are you sure?",
        text: "You will not be able to recover this imaginary file!",
        type: "warning",
        showCancelButton: true,
        confirmButtonColor: "#dc3545",
        confirmButtonText: "Yes, delete it!",
        closeOnConfirm: false
    }, function () {

        $.ajax({
            type: 'GET',
            url: "http://localhost:82/reports.laravel.com/public/users/delete/"+id,
            data: {
                id: id,
                _token: token
                 },
            success: function (data) {
                console.log("it Work");
                if(data==true){
                    swal("Deleted!", "Your imaginary file has been deleted.", "success");
                }

            }         
        });
    });
}
</script>

控制器： 

class UserController extends Controller
{
    public function destroy($id)
        {
            $user = User::find($id);
            $deleted = $user->delete();
            if($deleted){
                return true;
            }
        }
}

进行相应更改：

路线： 

Route::delete('users/delete/{id}','UserController@destroy');

控制器： 

class UserController extends Controller
{
    public function destroy($id)
        {
            $deleted = User::find($id)->delete();
            if($deleted){
                return true;
            }
        }
}

HTML： 

 $.ajax({
            type: 'DELETE',
            url: "http://localhost:82/reports.laravel.com/public/users/delete/"+id,
            data: {
            "_token": "{{ csrf_token() }}",
            "id": id
            }
            success: function (data) {
                console.log("it Work");
                if(data==true){
                    swal("Deleted!", "Your imaginary file has been deleted.", "success");
                }

            }         
        });

如果无法在这样的数据中添加令牌，则请显示错误

"_token": "{{ csrf_token() }}",

eports.laravel.com \ vendor \ symfony \ http-foundation \ Response.php：394） [stacktrace]

关于错误，这是因为您要在控制器中返回布尔值true，因为您是通过ajax调用触发UserController@destroy控制器的，所以我们建议您这样做

class UserController extends Controller
{
    public function destroy(Request $request)
    {
        $user = User::findOrFail($id);
        if($request->ajax()) {
            $user->delete();
            return response()->json(['deleted' =>> true, 'user' => $user]);
        } else {
            $user->delete();
            return response()->setContent(true);
        }
    }
}
