我有以下控制器:
public class CustomerController : ApiController
{
private ICustomerService customerService;
public CustomerController(ICustomerService customerService)
{
this.customerService= customerService;
}
public IEnumerable<Customer> GetAll()
{
return customerService.GetAll();
}
[HttpGet]
public Customer GetCustomer(int id)
{
//Get customer code...
return customer;
}
[ActionName("Save")]
[AcceptVerbs("PUT")]
[HttpPost]
public int SaveCustomer(Customer customer)
{
//Save customer code...
return customer.id;
}
[ActionName("Test")]
[HttpGet]
public string TestCustomer()
{
return "test";
}
[HttpDelete]
public bool DeleteCustomer(int id)
{
//Delete customer code...
return false;
}
}
我有以下默认的RouteConfig:
public class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
}
以及以下默认WebApiConfig:
public static class WebApiConfig
{
public static void Register(HttpConfiguration config)
{
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
config.EnableSystemDiagnosticsTracing();
}
}
当我尝试~api/Customer时,我会得到以下错误:找到多个与请求匹配的操作:类型MyApp.API.Controllers.PriceLevelController上的System.Collections.Generic.IEnumerable'1[Customer]GetAll()类型MyApp.API.Controllers.CustomerController 上的System.String TestCustomer()
我需要对我的路由配置进行哪些更改,以便在从客户端调用时,我的默认方法和自定义方法都能正常工作?
我认为当您的控制器中有多个具有相同参数的get方法时,就会出现此错误。您必须在配置文件中写入另一个Routes。
