如何添加帶有 DateTime 參數的操作？

Question

我想向我的Invoices控制器添加一個 Action，它有一個DateTime參數：

這是我的控制器和我的動作：

[Route("api/[controller]")]
public class InvoicesController : Controller
{
    private readonly IInvoiceRepository _repository;
    private readonly ILogger<InvoicesController> _logger;
    public InvoicesController(IInvoiceRepository repository, ILogger<InvoicesController> logger)
    {
        _repository = repository;
        _logger = logger;
    }

    [HttpGet]
    public IActionResult FilterBy(DateTime date)
    {
        try
        {
            return Ok(_repository.GetInvoicesByDate(date));
        }
        catch (Exception ex)
        {
            string errorMessage = "Failed to get invoices by date";
            _logger.LogError("{0} {1}", errorMessage, ex);
            return BadRequest(errorMessage);
        }
    }
}

我在startup.cs文件中有這一行：

    // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }

        app.UseMvc(routes =>
            routes.MapRoute(
                name: "getInvoicesByDate",
                template: "api/Invoices/{action}/{date:DateTime}",
                defaults: new { controller = "Invoices", action = "FilterBy" }));
    }

我的代碼有什么問題？ 謝謝

我想要一個 URL：格式http://domain/api/invoices/filterby/2017-01-01

嗯..我認為這不是 ASP.NET WebAPI 的典型路由和參數，我也不確定它是 WebSite 還是 WebAPI。

它對我有用（網址格式如：domain/api/invoices/filterby/2017-01-01）：

[Route("api/[controller]")]
public class InvoicesController : Controller
{
    
    [HttpGet("[action]/{date}")]
    public IActionResult FilterBy(DateTime date)
    {
        try
        {
            return Ok(date);
        }
        catch (Exception ex)
        {
            string errorMessage = "Failed to get invoices by date";
            return BadRequest(errorMessage);
        }
    }
}

在我看來，我想讓它變得簡單：只使用 WebAPI 的路由屬性。

只使用 app.UseMvc(); 在 Startup.cs

在控制器中添加路由屬性：

最后，確保您的 WebAPI url 帶有參數（HTTP GET）

http://localhost:xxxx/api/Invoices/FilterBy?date=2017-01-01
