如何使用DateTime参数添加Action？

Question

我想在我的Invoices控制器中添加一个操作，该控制器具有DateTime参数：

这是我的控制器与我的行动：

[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文件中有这一行：

    // 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" }));
    }

我的代码有什么问题？谢谢

我想要一个网址：格式http://domain/api/invoices/filterby/2017-01-01

HM .. 我认为它不是ASP.NET WebAPI的典型路由和参数，我也不确定它是WebSite还是WebAPI。

它适用于我（网址格式如：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);
        }
    }
}

在我看来，我想说的很简单：只使用带有WebAPI的route属性。

仅使用app.UseMvc（）;在Startup.cs

中

在contorller中添加路由属性：

最后，确保您的WebAPI网址带参数（HTTP GET）

  

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