C＃Net Core 2.0重构

Question

为控制器编写代码可能导致一次又一次地重复自己。如何重用下面的代码并将DRY原理应用于C＃Net Core 2.0。MVC控制器？请参见以下示例。使用EF和Web API获取部门的完整列表的代码如下。[HttpGet]public async Task<IActionResult> Department(){    using (var client = await _apiHttpClient.GetHttpClientAsync())    {        var response = await client.GetAsync("api/Department");        if (response.IsSuccessStatusCode)        {            var content = await response.Content.ReadAsStringAsync();            var dptos = JsonConvert.DeserializeObject<Department[]>(content);            return View(dptos);        }        if (response.StatusCode == HttpStatusCode.Unauthorized || response.StatusCode == HttpStatusCode.Forbidden)            return RedirectToAction("AccessDenied", "Authorization");        throw new Exception($"A problem happened while calling the API: {response.ReasonPhrase}");    }}确实只有一个部门几乎是相同的。[HttpGet]public async Task<IActionResult> DeparmentEdit(string id){    ViewData["id"] = id;    using (var client = await _apiHttpClient.GetHttpClientAsync())    {        var response = await client.GetAsync($"api/Department/{id}");        if (response.IsSuccessStatusCode)        {            var content = await response.Content.ReadAsStringAsync();            var dpto = JsonConvert.DeserializeObject<Department>(content);            return View(dpto);        }        if (response.StatusCode == HttpStatusCode.Unauthorized || response.StatusCode == HttpStatusCode.Forbidden)            return RedirectToAction("AccessDenied", "Authorization");        throw new Exception($"A problem happened while calling the API: {response.ReasonPhrase}");    }}_apiHttpClient字段包含HttpClient的自定义实现，用于令牌和刷新令牌以访问Web API。我认为在这里应用重构和DRY无关紧要，但是无论如何，我将在下面复制他的实现。无线电通信局，并预先感谢您的答复。
