javascript - 如何使用 Datatable 以 POST 类型传递请求正文数据以使用 Javascript 进行服务器端分页

Question

我正在尝试使用数据表为 AJAX POST 请求实现服务器端分页

这是我的 Javascript 代码，如果我将 JSON.stringify 用于数据字段，那么 api 将不会命中

$('#tripboard_table').DataTable({
    proccessing: true,
    serverSide: true,
    ajax: {
        "url": "http://localhost:5000/api/v1/trip/get-trip-list",
        "contentType": "application/json; charset=utf-8",
        "type": "POST",
        "dataType": "json",
        "data": {
            "driver_id": "",
            "franchise_id": login_data.franchise_id,
            "page_no": 0,
            "page_size": 10
        }
    },
    columns: [
        { "data": "" },
        { "data": "reference_number" },
        { "data": "consignor_name" },
        { "data": "consignee_name" },
        { "data": "from_city" },
        { "data": "to_city" },
        { "data": "status" },
        { "data": "route_name" },
        { "data": "vehicle_number" },
        { "data": "driver_name" },
        { "data": "pickup_date" },
        { "data": "scheduled_delivery_date" },
        { "data": "total_money_allocated" },
        { "data": "total_money_released" }
    ]



});

如果我们从数据中删除 JSON.stringify 函数并按原样传递数据，那么 api 会被命中并显示错误警报

DataTables warning: table id=tripboard_table - Ajax error. For more information about this error, please see http://datatables.net/tn/7

并且表中没有插入数据。 在控制台中显示

Method Not Allowed The method is not allowed for the requested URL.

请为此提出解决方案..

使用它来添加到数据表的现有请求

function (d) {
                d.driver_id = "";
                d.franchise_id = login_data.franchise_id;
                d.page_no = 0;
                d.page_size = 10;
                return d;
            }

                d.page_no = 0;
                d.page_size = 10;
                return JSON.stringify(d)
                });
            }
        },
        columns: [
            { "data": "" },
            { "data": "reference_number" },
            { "data": "consignor_name" },
            { "data": "consignee_name" },
            { "data": "from_city" },
            { "data": "to_city" },
            { "data": "status" },
            { "data": "route_name" },

            { "data": "total_money_released" }
        ]
    
    

    });
