如何从管理端获取数据然后显示在客户端？

Question

admin端目前有3个职位空缺，我想在客户端carrer页面显示它们如果管理员端删除所有空缺则显示客户端现在没有空缺

管理员端（使用entity framework）：

        [HttpGet]
        [AllowAnonymous]
        public ActionResult DisplayVacancyData()
        {
            var list = _dbfltEntities.tbl_vacancy.ToList();
            return View(list);
        }

查看管理员侧视图：

客户端（不使用entity framework）

HomeController.cs

        [HttpGet]
        public async Task<ActionResult> Career(Vacancy _vacancy)
        {
            HttpClient client = new HttpClient();
            HttpResponseMessage responseMessage = client.GetAsync("https://localhost:44325/Home/DisplayVacancyData").Result;

            if (responseMessage.IsSuccessStatusCode)
            {
                await responseMessage.Content.ReadAsStringAsync();
            }
            return View();
        }

看到响应没问题，但是应该应用哪个逻辑来显示数据

vacancy.cs

    public class Vacancy
    {
        public int vacancyid { get; set; }
        public string vacancytitle { get; set; }
        public string vacancyposition { get; set; }
        public string vacancyexperience { get; set; }
        public string vacancyjobdescription { get; set; }
        public string vacancyrequiredskil { get; set; }
    }

careerpage.cshtml

<style type="text/css">
    .actionlink {
        font-size: 25px;
        color: cornflowerblue;
    }
</style>

<div class="container">
    <div class="row">
        <div class="col-md-6">
            <h2 style="margin-top:150px;">Current Job Openings</h2>
        </div>
        <div class="col-md-4" style="margin-top:155px;">
            @Html.ActionLink("Apply for Job", "ApplyForJob", null, new { @class = "actionlink" })
        </div>
    </div>
    <div class="row">
        <p> ssss ss sss a sss s of an ss-sssss s ss? s ss with s, ssss s enthusiassm s s? s s aside s s s s s s. s over ssss s s s s s sss below:</p>
    </div>
</div>

我正在尝试使用 viewbag 获取数据

HomeController.cs

            if (responseMessage.IsSuccessStatusCode)
            {
                await responseMessage.Content.ReadAsStringAsync();

                ViewBag.vacancytitle = _vacancy.vacancytitle;  //I am seeing in watch window but it is null

            }

访问职业视图页面中的视图包

@ViewBag.vacancytitle

帮助

Return 函数 responseMessage.Content.ReadAsStringAsync() 的值被忽略。

管理员端（使用entity framework），添加操作 (return json):

    [HttpGet]
    [AllowAnonymous]
    public ActionResult GetVacancyData()
    {
        var list = _dbfltEntities.tbl_vacancy.ToList();
        return new JsonResult(list);
    }

HomeController.cs
（客户端 URI“https://.../Home/GetVacancyData”）

   [HttpGet]
    public async Task<ActionResult> Career()
    {
        HttpClient client = new HttpClient();
        HttpResponseMessage responseMessage = client.GetAsync("https://localhost:44325/Home/GetVacancyData").Result;

          if (responseMessage.IsSuccessStatusCode)
        {
            string result = await responseMessage.Content.ReadAsStringAsync();
            List<Vacancy> products = JsonConvert.DeserializeObject<List<Vacancy>>(result);
            return View(products);
        }

        return View();
    }

careerpage.cshtml

  @foreach (var item in Model)
    {
        <p>@item.vacancytitle</p>
    }
