ASP.NET Core Webb API 中的多个 HttpPost 方法

Question

我无法在 ASP.NET Core 中处理我的路由规则。我有以下用户身份验证操作方法的后端和前端应用程序。由于这两种操作方法在有效负载中都有一个带有不同或附加参数的参数。 Http 客户端实际上无法导航确切的方法，因此抛出一个带有错误“歧义”的异常，这是正确的，因为这两种 HttpPost 方法都有一个具有不同参数的参数。如何确保该方法根据操作触发。代码如下：-

API 控制器：-

  [Route("api/[controller]")]
  public class AccountController: Controller
  {
         [HttpPost, ActionName("Login")]
         public async Task<IActionResult> UserLogin(LoginDto user)
         {
            //Code goes here
         }

        [HttpPost, ActionName("Register")]
        [ValidateAntiForgeryToken]
        public async Task<IActionResult> UserRegistration(RegisterDto register)
        {
             //Code goes here
        }
  }

前端 API 服务

   public async Task<IActionResult> GetLoginAsync(LoginDto loginUser)
   {
                var request = "/api/account";
                var content = new StringContent(JsonConvert.SerializeObject(loginUser), Encoding.UTF8, "application/json");
                try
                {
                    var result = await ExecuteWithResiliencePolicies(() => _client.PostAsync(request, content));
                    return new StatusCodeResult((int)result.StatusCode);

                }
                catch (HttpRequestException)
                {
                    return new StatusCodeResult(StatusCodes.Status503ServiceUnavailable);
                }           
     }

     public async Task<IActionResult> PostRegistrationAsync(RegisterDto registerUser)
     {
                var request = "/api/account";
                var content = new StringContent(JsonConvert.SerializeObject(registerUser), Encoding.UTF8, "application/json");
                try
                {
                    var result = await ExecuteWithResiliencePolicies(() => _client.PostAsync(request, content));
                    return new StatusCodeResult((int)result.StatusCode);

                }
                catch (HttpRequestException)
                {
                    return new StatusCodeResult(StatusCodes.Status503ServiceUnavailable);
                }
      }

网络控制器：-

     [HttpPost, ActionName("Login")]
            [ValidateAntiForgeryToken]
            public async Task<IActionResult> UserLogin(LoginDto user)
            {
                SetCorrelation();
                if (!ModelState.IsValid)
                {
                    return RedirectToAction(nameof(Login));
                }
                await _accountService.GetLoginAsync(user);              
                return RedirectToAction("Index", "Home");
            }

            [HttpPost, ActionName("Register")]
            [ValidateAntiForgeryToken]
            public async Task<IActionResult> UserRegistration(RegisterDto register)
            {
                SetCorrelation();
                if (!ModelState.IsValid)
                {
                    return RedirectToAction(nameof(Login));
                }
                await _accountService.PostRegistrationAsync(register);
                return RedirectToAction("Index", "Home");


}

网络路由：

app.UseMvc(routes =>
            {
                routes.MapRoute(
                    name: "WebRoute",
                    template: "{controller}/{action}/{id?}",
                    defaults: new { controller = "Home", action = "Index" },
                    constraints: new { id = "[0-9]+" });                
            });

API 路由：-

app.UseMvc(routes =>
            {
                routes.MapRoute(
                    name: "KtsWebAPIRoute",
                    template: "{controller=Posts}/{action=GetAsync}/{id?}");

                routes.MapRoute(
                    name: "KtsAccountRoute",
                    template: "{controller}/{action}/{id?}",
                    defaults: new { controller = "Account", Action = "Login" },
                    constraints: new { id = "[0-9]+" });
            });

有几种可能的解决方案。对于每个解决方案前端部分都应调用以下网址

"/api/account/login"
"/api/account/register"

解决方案 1

您需要在HttpPost属性中指定模板 ASP.NET Core 路由无法从请求中获取操作名称

[Route("api/[controller]")]
public class AccountController : Controller
{
    [HttpPost("Login")]
    public async Task<IActionResult> UserLogin(LoginDto user) { /*..*/ }
}

或者你可以将模板与ActionName结合起来

[Route("api/[controller]")]
public class AccountController : Controller
{
    [HttpPost("[action]"), ActionName("Login")]
    public async Task<IActionResult> UserLogin(LoginDto user) { /*..*/ }
}

解决方案 2

更新控制器的路由以包含动作名称

[Route("api/[controller]/[action]")]
public class AccountController : Controller
{
    [HttpPost, ActionName("Login")]
    public async Task<IActionResult> UserLogin(LoginDto user) { /*..*/ }
}

解决方案 3

使用Route 属性进行操作

[Route("api/[controller]")]
public class AccountController : Controller
{
    [HttpPost, Route("Login")]
    public async Task<IActionResult> UserLogin(LoginDto user) { /*..*/ }
}

Answer 2

使用 apiController 属性和 ControllerBase

[ApiController]
[Route("api/[controller]/[action]")]
public class AccountController : ControllerBase
{
.....
}

网址应该是这样的

var uri = "............/api/Account/Login"
