Question

我在web api中有两个或更多get方法（如下所示，代码GetProducts和GetProductsNew是get方法）。因为我正在使用角度js的ng-resource，每当我尝试调用get函数时，它都会给出一个模糊的错误。假设我想调用GetProductsNew方法然后我怎么调用？任何人都可以帮忙，提前谢谢：）

    // This is my web api code
    public class ProductController : ApiController
    {
      ...
      public HttpResponseMessage GetProducts()
      { 
      }

      public HttpResponseMessage GetProductsNew()
      {
      }
    }

    // **This is my angular** 

    // This is the code in controller.js, using which i am calling the get method from above code, but here the problem is, since the above web api is having the two gt method, i am getting the "Multiple actions were found that match the request"

    productcatControllers.controller('ProductListCtrl', ['$scope', '$routeParams',
    '$location', '$route', 'productService',
    function ($scope, $routeParams, $location, $route, productService) 
    {
        productService.query(function (data) {
            $scope.products = data;
        });
    }]);

   // This is the service of angular js
   var phonecatServices = angular.module('productcatServices', ['ngResource']);

   phonecatServices.factory("productService", function ($resource) {
       return $resource(
           "/api/Product/:id",
           { id: "@id" },
           {
              "update": { method: "PUT" }

           }
       );
   });

出现模糊错误＆＃39;我猜你得到了：＆＃34;找到了与请求匹配的多个操作....＆＃34; ？这是因为在同一个控制器中不能有多个具有相同签名的Get方法。

尝试将这些属性添加到webapi中的方法

public class ProductController : ApiController
{
  [HttpGet]
  [Route(Name = "GetProducts")]
  public HttpResponseMessage GetProducts()
  { 
  }

  [HttpGet]
  [Route(Name = "GetProductsNew")]
  public HttpResponseMessage GetProductsNew()
  {
  }
}

如果您尚未安装，请安装 AspNet.WebApi.WebHost ：

Install-Package Microsoft.AspNet.WebApi.WebHost
