早安,
我在设置 HTTPGET 并在 Postman 中测试解决方案时遇到了困难.
我试图在两种情况下都返回一个结果,但是当我输入参数时,什么都没有加载.所以我显然错过了一些我需要帮助的东西.
我的 CashMovementController 中有 1 个参数 {id},如果我导航到 localhost/api/cashmovements/{id} 它会加载但是如果在邮递员中传递 {id} 参数它会失败.
然后在我的 BondCreditRatingsController 我有 2 个参数 {ISIN} &{Date},我不知道该如何处理.
希望听到一些建议/帮助
感谢GWS
Startup.cs
app.UseMvc(routes =>{路线.MapRoute(名称:默认",模板:{controller=Home}/{action=Index}/{id?}");});CashMovementsController.cs
[Route("api/[controller]")]公共类 CashMovementsController : 控制器{私人 ICashMovementRepository _cashmovementRepository;[HttpGet("{id}", Name = "GetCashMovement")]公共 IActionResult 获取(int id){CashMovement _cashmovement = _cashmovementRepository.GetSingle(u => u.CashMovementId == id);如果(_cashmovement != null){CashMovementViewModel _cashmovementVM = Mapper.Map(_cashmovement);返回新的 OkObjectResult(_cashmovementVM);}别的{返回未找到();}}}BondCreditRatingsController.cs
[Route("api/[controller]")]公共类 BondCreditRatingsController : 控制器{私人 IBondCreditRatingRepository _bondcreditratingRepository;公共 BondCreditRatingsController(IBondCreditRatingRepository bondcreditratingRepository){_bondcreditratingRepository = bondcreditratingRepository;}[HttpGet("{id}", Name = "GetBondCreditRating")]公共 IActionResult 获取(字符串 id,日期时间有效日期){BondCreditRating _bondcreditrating = _bondcreditratingRepository.GetSingle(u => u.ISIN == id, u => u.EffectiveDate == efffectivedate);如果(_bondcreditrating != null){BondCreditRatingViewModel _bondcreditratingVM = Mapper.Map(_bondcreditrating);返回新的 OkObjectResult(_bondcreditratingVM);}别的{返回未找到();}} 解决方案如果你想将它映射到 api/Controller/method/id 你需要使用下面的代码,因为你想映射参数顺序(没有其他标识符) 到动作中的特定参数名称.
[HttpGet("GetCashMovement/{id}")]由于您使用的是命名参数并且请求无法映射到任何其他模板,因此您当前的代码应该可以在下面使用.
/api/CashMovements/GetCashMovement?id=1但该属性语法也会(可能无意)触发:
/api/CashMovements/1由于您为该操作定义的模板的总和是:
[Route("api/[controller]/{id}")]/api/ApiTest/GetCashMovement 映射 GetCashMovement.Get(int i) 的原因是因为 id 在启动时被定义为可选
routes.MapRoute(名称:默认",模板:{controller=Home}/{action=Index}/**{id?}**");路由参数名称后的问号 (?) 定义了一个可选参数参数.

Good Morning,
I’m having difficulty setting up my HTTPGETs and then testing the solution in Postman.
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.
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.
Then in my BondCreditRatingsController I have 2 parameters {ISIN} & {Date} and again I'm not sure how to approach this.
Love to hear some advice/help on this please
Thanks 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(); } }解决方案
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}")]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=1But that attribute syntax will also (possibly unintentionally) trigger:
/api/CashMovements/1Since a sum of your defined template for that action is:
[Route("api/[controller]/{id}")]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?}**");
A question mark (?) after the route parameter name defines an optional parameter.
