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载荷中都有一个参数不同或附加参数。Http 客户端实际上无法导航精确的方法，因此会抛出一个错误“歧义”的异常，这是真的，因为这两个 HttpPost 方法都有一个带有不同参数的参数。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);
                }
      }

网页控制器：-

     [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]+" });
            });

Answer 1

有几种可能的解决方案。对于每个解决方案前端部分应调用以下网址

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

解决方案1

您需要在HttpPost属性 ASP.NET Core 路由中指定模板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) { /*..*/ }
}

或者您可以将模板与 ActionName

[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操作名称

[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) { /*..*/ }
}
