ASP.. NET核心HttpGet单一Web API

Question

早上好

我有困难设置我的HTTPGETs，然后在邮差测试解决方案。

我试图在这两种情况下返回一个结果，但是当我输入参数时没有加载。所以我显然遗漏了一些东西，我需要一些帮助。

我有一个参数{id}在我的CashMovementController，如果我导航到localhost/api/cashmovements/{id}它加载，但如果传递{id}参数在邮差失败。

然后在我的BondCreditRatingsController我有2个参数{ISIN} &{日期}，我不确定如何处理这个

希望听到一些建议/帮助在这方面，请

谢谢取而代之

Startup.cs

        app.UseMvc(routes =>
        {
            routes.MapRoute(
                name: "default",
                template: "{controller=Home}/{action=Index}/{id?}");
        });

CashMovementsController.cs

    private ICashMovementRepository _cashmovementRepository;
    [HttpGet("{id}", Name = "GetCashMovement")]
    public IActionResult Get(int id)
    {
        CashMovement _cashmovement = _cashmovementRepository.GetSingle(u => u.CashMovementId == id);
        if (_cashmovement != null)
        {
            CashMovementViewModel _cashmovementVM = Mapper.Map<CashMovement, CashMovementViewModel>(_cashmovement);
            return new OkObjectResult(_cashmovementVM);
        }

        {
            BondCreditRatingViewModel _bondcreditratingVM = Mapper.Map<BondCreditRating, BondCreditRatingViewModel>(_bondcreditrating);

如果你想将它映射到api/Controller/method/id，你需要使用下面的代码，因为你想将参数顺序(没有其他标识符)映射到动作中的特定参数名称。

[HttpGet("GetCashMovement/{id}")]

由于你使用的是命名参数，并且请求不能映射到任何其他模板，所以你当前的代码应该使用下面的代码。

/api/CashMovements/GetCashMovement?id=1

但是这个属性语法也会(可能是无意的)触发:

/api/CashMovements/1

因为该动作的定义模板的总和是:

[Route("api/[controller]/{id}")]

/api/ApiTest/GetCashMovement映射GetCashMovement的原因Get(int i)是因为id在startup

中定义为可选的

routes.MapRoute(
    name: "default",
    template: "{controller=Home}/{action=Index}/**{id?}**");

路由参数名后面的问号定义了一个可选参数。
