如何使用ASP.NET Core,2.0中的Razor Pages处理Ajax请求

Question

下面我试图在CustomerModel Razor Pages中制作一个Post Request to Action方法/处理程序.

RazorPage名称是"Customer.cshtml"

从Ajax请求绑定DropdownList

<div class="col-xs-12 col-sm-6 col-md-6 col-lg-4">
<select class="form-control" id="CustomerID" 
        name="CustomerID" 
        asp-for="Customer.CustomerID"
        asp-items="@(new SelectList(string.Empty,"CustomerID", "Name"))">
</select>

Ajax请求

我也尝试只调用处理程序,但它显示错误

<script type="text/javascript">
$(document).ready(function ()
{
    $.ajax({
            type: 'GET',
            // we are calling json method

            // /Pagename/ActionMethod
            // /Pagename/Handler(OnGetListofCustomer)

            url: '/Customer/OnGetListofCustomer', 
            contentType: "application/json",
            success: function (data) {
                $("#CustomerID").append('<option value="' + "0" + '">' + "Select State" + '</option>');
                debugger;
                $.each(data, function (i, state) {
                    $("#CustomerID").append('<option value="' + state.CustomerID + '">' + state.Name + '</option>');
                });
            },
            error: function (ex) {
                alert('Failed to retrieve states.' + ex);
            }
        });
});

PageModel

发出Ajax请求时出错

我不认为你能够像这样访问剃刀页面动作方法.你能这样试试吗？

$.getJSON("/Customer?handler=ListofCustomer",function(data){
    //Do something with the data.
});

因为要访问除默认OnGet或OnPost方法之外的任何方法,我们需要处理程序,其内部运行时映射到方法.
