laravel中ajax請(qǐng)求一直報(bào)parsererror錯(cuò)誤

laravel5.4中使用ajax請(qǐng)求控制器接口一直報(bào)錯(cuò)
admin.js

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

$(".post-audit").click(function(){
    var status = $(this).attr("post-action-status");
    var post_id = $(this).attr("post-id");
    var _self = $(this);
    $.ajax({
        url: "/admin/post/"+post_id+"/operate",
        method: "POST",
        data: {"status": status},
        dataType:"json",
        success: function handleSuccess(data){
            console.log(data);
            //操作后該項(xiàng)不顯示
            //_self.parent().parent().remove();
        },
        error: function(xhr, type){
            console.log(type);
        }
    });
});

控制器

public function operate(Post $post)
    {
        return ['code'=>200,'msg'=>'測(cè)試'];
        /*$this->validate(request(), [
            "status" => 'required|in:-1,1',
        ]);

        $post->status = request('status');
        $post->save();
        return response()->json([
            'error' => 0,
            'msg' => ''
        ]);*/
    }

上面的請(qǐng)求瀏覽器控制臺(tái)一直提示parsererror：

但是將返回?cái)?shù)據(jù)寫在路由里又是正常的

Route::post('/admin/post/{post}/operate',function(){
    return ['code'=>200,'msg'=>'測(cè)試']; 
})->where('post','[0-9]+');

瀏覽器控制臺(tái)輸出：

小弟新手，請(qǐng)大神多多指教
