我可以得到数据从web api在.net核心与另一个api或api密钥?

Question

我写了一个控制器。我根据我将在这里使用的web api编写了它。但我该如何创建自己的api呢?我需要有我自己创建的api，我写与HttpPost?我可能是错的，因为我是新手。

public class GoldPriceDetailController : Controller
{
string Baseurl = "https://apigw.bank.com.tr:8003/";
public async Task<ActionResult> GetGoldPrice()
{
List<GoldPrice> goldPriceList = new List<GoldPrice>();
using (var client = new HttpClient())
{
//Passing service base url  
client.BaseAddress = new Uri(Baseurl);
client.DefaultRequestHeaders.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
//Sending request to find web api REST service resource GetDepartments using HttpClient  
HttpResponseMessage Res = await client.GetAsync("getGoldPrices");
Console.WriteLine(Res.Content);
//Checking the response is successful or not which is sent using HttpClient  
if (Res.IsSuccessStatusCode)
{
var ObjResponse = Res.Content.ReadAsStringAsync().Result;
goldPriceList = JsonConvert.DeserializeObject<List<GoldPrice>>(ObjResponse);
}
//returning the student list to view  
return View(goldPriceList);
}
} 

[HttpPost]
public async Task<IActionResult> GetReservation(int id)
{
GoldPrice reservation = new GoldPrice();
using (var httpClient = new HttpClient())
{
using (var response = await httpClient.GetAsync("https://apigw.bank.com.tr:8443/getGoldPrices" + id))
{
if (response.StatusCode == System.Net.HttpStatusCode.OK)
{
string apiResponse = await response.Content.ReadAsStringAsync();
reservation = JsonConvert.DeserializeObject<GoldPrice>(apiResponse);
}
else
ViewBag.StatusCode = response.StatusCode;
}
}
return View(reservation);
}
}

基本上需要以下步骤:

• HttpClient用于本地API。
• HttpClient用于外部API
本地API控制器。
• 将外部客户端注入本地API。
• 将本地API客户端注入到razor页面/控制器中。

HttpClient for Local API

public class LocalApiClient : ILocalHttpClient
{
private readonly HttpClient _client;
public LocalAPiClient(HttpClient client)
{
_client = client;
_client.BaseAddress(new Uri("https://localapi.com"));
}
[HttpGet]
public async Task<string> GetGoldPrices(int id)
{
// logic to get prices from local api
var response = await _client.GetAsync($"GetGoldPrices?id={id}");
// deserialize or other logic
}
}

HttpClient for External API

public class ExternalApiClient : IExternalHttpClient
{
private readonly HttpClient _client;
public ExternalAPiClient(HttpClient client)
{
_client = client;
_client.BaseAddress(new Uri("https://externalApi.com"));
// ...
}
[HttpGet]
public async Task<string> GetGoldPrices(int id)
{
// logic to get prices from external api
var response = await _client.GetAsync("getGoldPrices?id=" + id))
}
}

在startup中注册您的客户端

services.AddHttpClient<ILocalHttpClient, LocalHttpClient>();
services.AddHttpClient<IExternalHttpClient, ExternalHttpClient>();

创建本地API控制器

并将外部HTTP客户端注入其中

[ApiController]
public class LocalAPIController : Controller
{
private readonly IExternalHttpClient _externalClient;
public LocalAPIController(IExternalHttpClient externalClient)
{
_externalClient = externalClient;
}
[HttpGet]
public async Task<string> GetGoldPrices(int id)
{
var resoponse = await _externalClient.GetGoldPrices(id);
// ...
}
}

将本地客户端注入razor页面/控制器

public class HomeController : Controller
{
private readonly ILocalHttpClient _localClient;
public HomeController(ILocalHttpClient localClient)
{
_localClient = localClient;
}
public async Task<IActionResult> Index(int id)
{
var response = await _localClient.GetGoldPrices(id);
// ...
}
}
