.ajax删除方法不起作用

Question

我的DELETE请求有问题。当方法存在时，它会保持返回404找不到。我尝试过POST方法，但它确实有用，所以我不知道发生了什么。下面是我的请求方法的jQuery。

$(document).ready(function () {
    var table = $('#example').DataTable();

    $('#example tbody').on('click', 'tr', function () {
        if ($(this).hasClass('selected')) {
            $(this).removeClass('selected');

        } else {
            table.$('tr.selected').removeClass('selected');
            $(this).addClass('selected');

        }
    });
    $('#button').click(function () {
        var person = new Object();
        var dbname = document.getElementById('Label2');
        //alert(dbname.innerHTML);//db table name
        var data = table.cell('.selected', 0).data()
        //alert(String(data));//ID
        person.name = dbname.innerHTML;
        person.surname = String(data);
        $.ajax({
            url: "http://172.20.129.139/fa/summary.aspx/relic",
            type: "delete",
            async: false,
            data: person,
            dataType: "json",
            success: function (data) {
                alert('Submitted!');
            },
            error: function (result) {
                alert('Oh no :(');
            }
        });
    });
});

以下是summary.aspx / relic的代码

 [WebMethod]
    public string relic(person data)
    {
        dynamic result = data;
        SqlConnection con = new SqlConnection(WebConfigurationManager.ConnectionStrings["hey"].ConnectionString);
        con.Open();
        string query = "delete from "+data.name+" where ID= '"+data.surname+"'";
        SqlCommand com = new SqlCommand(query, con);
        com.ExecuteNonQuery();
        con.Close();
        return result;
    }
