早上好,
我在设置HTTPGET并在Postman中测试解决方案时遇到困难。
I’m having difficulty setting up my HTTPGETs and then testing the solution in Postman.
我试图在两种情况下都返回单个结果,但是当我输入参数时,没有任何结果。因此,我显然缺少一些需要帮助的东西。
I’m trying to return a single result on both occasions however when I input the parameters nothing loads. So I'm clearly missing something which i need some help on please.
我的CashMovementController中有1个参数{id},如果我导航到localhost / api / cashmovements / {id}会加载,但是如果在邮递员中传递{id}参数会失败。
I have 1 parameter {id} in my CashMovementController and if I navigate to localhost/api/cashmovements/{id} it loads however if pass the {id} parameter in postman it fails.
然后在我的BondCreditRatingsController中,我有2个参数{ISIN}& {Date},我不确定如何处理此问题。
Then in my BondCreditRatingsController I have 2 parameters {ISIN} & {Date} and again I'm not sure how to approach this.
喜欢听听一些建议/帮助
Love to hear some advice/help on this please
感谢GWS
Startup.cs
app.UseMvc(routes => { routes.MapRoute( name: "default", template: "{controller=Home}/{action=Index}/{id?}"); });CashMovementsController.cs
[Route("api/[controller]")] public class CashMovementsController : Controller { 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); } else { return NotFound(); } } }BondCreditRatingsController.cs
[Route("api/[controller]")] public class BondCreditRatingsController : Controller { private IBondCreditRatingRepository _bondcreditratingRepository; public BondCreditRatingsController(IBondCreditRatingRepository bondcreditratingRepository) { _bondcreditratingRepository = bondcreditratingRepository; } [HttpGet("{id}", Name = "GetBondCreditRating")] public IActionResult Get(string id, DateTime efffectivedate) { BondCreditRating _bondcreditrating = _bondcreditratingRepository.GetSingle(u => u.ISIN == id, u => u.EffectiveDate == efffectivedate); if (_bondcreditrating != null) { BondCreditRatingViewModel _bondcreditratingVM = Mapper.Map<BondCreditRating, BondCreditRatingViewModel>(_bondcreditrating); return new OkObjectResult(_bondcreditratingVM); } else { return NotFound(); } }推荐答案
如果您要将其映射到api / Controller / method / id,则需要使用下面的代码,因为要将参数顺序(无其他标识符)映射到操作中的特定参数名称。
If you want to map it to api/Controller/method/id you would need to use the code below because you want to map parameter order (no other identifier) to a specific parameter name in the action.
[HttpGet("GetCashMovement/{id}")]由于使用命名参数,并且无法将请求映射到任何其他模板,因此当前的代码应在下面使用。
Your current code should work with below since you are using named parameters and because the request can't be mapped to any other template.
/api/CashMovements/GetCashMovement?id=1但是该属性语法也会(可能是无意地)触发:
But that attribute syntax will also (possibly unintentionally) trigger:
/api/CashMovements/1由于您为该操作定义的模板的总和为:
Since a sum of your defined template for that action is:
[Route("api/[controller]/{id}")]原因为什么/ api / ApiTest / GetCashMovement映射GetCashMovement.Get(int i)是因为id在启动时被定义为可选
Reason to why /api/ApiTest/GetCashMovement maps GetCashMovement.Get(int i) is because id is defined as optional in startup
routes.MapRoute( name: "default", template: "{controller=Home}/{action=Index}/**{id?}**");
在路由参数名称定义可选字符后的问号(?) 参数。
A question mark (?) after the route parameter name defines an optional parameter.
