Question

VS 2012 MVC应用程序新手，第一次使用RESTful API（目前为at this point in the tutorial)而我似乎无法在Google Chrome中正确显示信息。设置了断点，如我的控制器中的教程所示（）函数，我知道它正在调用，当在浏览器中检查网络视图时，it sees both of my entries I'm trying to display。

我的代码几乎与示例完全相同，标题已被切换：

@{
    ViewBag.Title = "Index";
    Layout = "~/Views/Shared/_Layout.cshtml";
}

<div id="body">
    <ul id="drug_entries"></ul>
</div>

@section scripts{
<script type="text/javascript">
    $(function ()
    {
        $.getJSON('/api/DrugEntry', function (drugEntriesJsonPayload)
        {
            $(drugEntriesJsonPayload).each(function (i, item)
            {
                $('#drug_entries').append('<li>' > + item.NDC + '</li>');
            });
        });
    });
</script>
}

知道可能是什么原因导致它没有看到任何东西？或者，如果我能提供更多信息？谢谢！

我的route.config：

// <auto-generated/>
using System;
using System.Collections.Generic;
using System.Diagnostics.CodeAnalysis;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Web.Routing;

namespace MedicationsShortagesDashboard
{
[ExcludeFromCodeCoverage]
public class RouteConfig
{
    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
        );
    }
}
}

我的WebApiConfig.cs：

// <auto-generated/>
using System;
using System.Collections.Generic;
using System.Diagnostics.CodeAnalysis;
using System.Linq;
using System.Web.Http;

namespace MedicationsShortagesDashboard
{
    [ExcludeFromCodeCoverage]
    public static class WebApiConfig
    {
        public static void Register(HttpConfiguration config)
        {
            config.Routes.MapHttpRoute(
                name: "DefaultApi",
                routeTemplate: "api/{controller}/{id}",
                defaults: new { id = RouteParameter.Optional }
            );

            // Uncomment the following line of code to enable query support for actions with an IQueryable or IQueryable<T> return type.
            // To avoid processing unexpected or malicious queries, use the validation settings on QueryableAttribute to validate incoming queries.
            // For more information, visit http://go.microsoft.com/fwlink/?LinkId=279712.
            //config.EnableQuerySupport();

            // To disable tracing in your application, please comment out or remove the following line of code
            // For more information, refer to: http://www.asp.net/web-api
            config.EnableSystemDiagnosticsTracing();
        }
    }
}

在WebApiConfig.cs中添加此内容

using System.Net.Http.Headers;
using System.Web.Http;

namespace XXX
{
    public static class WebApiConfig
    {
        public static void Register(HttpConfiguration config)
        {
            // Convention-based routing.
            config.Routes.MapHttpRoute(
                name: "DefaultApi",
                routeTemplate: "api/{controller}/{id}"
            );
        }
    }
}
