DataTables警告，无效的JSON响应

问题描述

我无法从数据表中生成任何数据。它在localhost上运行良好，但是现在该站点托管在IIS上，但我收到无效的JSON响应。

我已经启动了开发工具，并在“网络”标签中获得了以下信息

下面是我的Jquery

var dataTable;

$(document).ready(function () {
    loadDataTable();
});

function loadDataTable() {
    dataTable = $('#DT-load').DataTable({
        "ajax": {
            "url": "/masks","type": "GET","datatype": "json","dataSrc": "data",},"columns": [
            { "data": "name","width": "20%" },{ "data": "author",{ "data": "isbn",{

                "data": "id","render": function (data) {
                    return `<div class="text-center">
                <a href="/MaskList/Edit?id=${data}" class='btn btn-success text-white' style='cursor:pointer; width:70px;'>
                Edit
                </a>
            &nbsp;
            <a  class='btn btn-danger text-white mx-auto' style='cursor:pointer; width:70px;'
                    onclick=Delete('/masks?id='+${data})>
            Delete
                </a>
                </div>`;
                },"width": "40"
            }

        ],"language": {
            "emptyTable": "No Data found"
        },"width": "100%"

    });

}


//Sweet Alert Function

function Delete(url) {
    swal({
        title: "Are you sure?",text: "Once Delete you will not be able to recover",icon: "warning",buttons: true,dangerMode: true
    }).then((willDelete) => {
        if (willDelete) {
            $.ajax({
                type: "DELETE",url: url,success: function (data) {
                    if (data.success) {
                        toastr.success(data.message);
                        dataTable.ajax.reload();
                    }
                    else {
                        toastr.error(message);
                    }

                }
            });
        }
    })

}

我的控制器看起来正确，并且在本地主机上工作正常

namespace MaskFit.Controllers
    {

    [Route("/mask")]
    [ApiController]
    public class MaskController : Controller
        {

        private readonly ApplicationDbContext _db;

        public MaskController(ApplicationDbContext db)
            {

            _db = db;

            }

        [HttpGet]

        public async Task<IActionResult> GetAll()
            {
            return Json(new { data = await _db.Mask.ToListAsync() });
            }

我在这里缺少明显的东西吗？任何帮助表示赞赏

解决方法

您应确保从服务器返回的数据包含如下属性数据：

{
  "data": [
            {...}
            {...}
          ]
}

否则，您应指定“ dataSrc”：“”
