ASP.NET MVC從Web API調用在幫助控制器中創建列表

Question

我正在嘗試創建一個幫助控制器，它將基本上向Web API發出一個GET請求，以創建一個最終將用於返回JSON數據的列表。我在網上找到了一個例子，幾乎可以做我想做的事，除了數據是在控制器內硬編碼的。

控制器（在C＃）：

public class StudentAPIController : Controller 
    { 
     // GET: api/GetAllStudents 
     [HttpGet] 
     public IEnumerable<PersonalDetail> GetAllStudents() 
     { 
      List<PersonalDetail> students = new List<PersonalDetail> 
      { 
      string uri = "URL_OF_API_CALL"; 

      new PersonalDetail{ 
    // Here is where I want to make the API call to fetch the data instead of this hard-coded data 
           RegNo = "2017-0001", 
           Name = "Nishan", 
           Address = "Kathmandu", 
           PhoneNo = "9849845061", 
           AdmissionDate = DateTime.Now 
           }, 
      new PersonalDetail{ 
           RegNo = "2017-0002", 
           Name = "Namrata Rai", 
           Address = "Bhaktapur", 
           PhoneNo = "9849845062", 
           AdmissionDate = DateTime.Now 
          },     
      }; 
      return students; 
     } 
    } 

任何幫助，不勝感激！

首先添加此庫：

System.Net.Http 

然後你就可以使用這些代碼行來調用另一個Web API放在你的助手控制器：

HttpClient client = new HttpClient(); 
client.BaseAddress = @"http://[YourBaseUri]/"; 
client.DefaultRequestHeaders.Accept.Clear(); 
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json")); 
var request = client.GetAsync("[YourActionName]"); 
return request.Result.Content.ReadAsStringAsync().Result;
