Question

我创建了这个ajax函数：

function getAssociatedProperties(callback, error) {
    $.ajax({
        url: '/LayerProperty/get',
        type: "GET",
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        data: 5,
        crossDomain: true,
        success: callback,
        error: function () {

        }
    });
}

这是我的网络API类：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Web.Http;

namespace GeomindMobile.Controllers
{
    public class LayerProperty : ApiController
    {
        // GET api/<controller>
        public IEnumerable<string> Get()
        {
            return new string[] { "value1", "value2" };
        }

        // GET api/<controller>/5
        public string Get(int id)
        {
            return "value";
        }

        // POST api/<controller>
        public void Post([FromBody]string value)
        {
        }

        // PUT api/<controller>/5
        public void Put(int id, [FromBody]string value)
        {
        }

        // DELETE api/<controller>/5
        public void Delete(int id)
        {
        }
    }
}

每当ajax函数触发时，我都会收到此错误：

http://localhost/LayerProperty/get 404 (Not Found)

更新

Here is my 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 }
            );
        }

我的代码有什么问题？为什么ajax调用没有成功？

Answer 1

function getAssociatedProperties(callback, error) {
    $.ajax({
        url: '/api/LayerProperty', // <--- You do not need the 'get' here, but you do need the /api/
        type: "GET",
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        data: 5,
        crossDomain: true,
        success: callback,
        error: function () {

        }
    });
}

Answer 2

你能用下面的代码改变你的方法吗？

[HttpGet]
public IEnumerable<string> get()
{
            return new string[] { "value1", "value2" };
}

Answer 3

将控制器名称与您的控制器一起使用然后它将从ajax请求触发，目前您没有在mvc中使用正确的命名约定。

您的

public class LayerProperty : ApiController

我的

public class LayerPropertyController : ApiController

Answer 4

你的网址有错误。

function getAssociatedProperties(callback, error) {
    $.ajax({
        url: '/api/LayerProperty/get',
        type: "GET",
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        data: 5,
        crossDomain: true,
        success: callback,
        error: function () {

        }
    });
}

为什么ajax呼叫不成功？
