使用Angularjs在MVC控制器中访问硬编码数据

Question

I have some knowledge about Angularjs but I'm new to ASP.NET MVC. So I was following this https://docs.microsoft.com/en-us/aspnet/web-api/overview/getting-started-with-aspnet-web-api/tutorial-your-first-web-api tutorial. But I came up with a problem as it uses Jquery. I want to access the hard coded data in below controller using Angular.

using ProductsApp.Models;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Web.Http;

namespace ProductsApp.Controllers
{
    public class ProductsController : ApiController
    {
        Product[] products = new Product[] 
        { 
            new Product { Id = 1, Name = "Tomato Soup", Category = "Groceries", Price = 1 }, 
            new Product { Id = 2, Name = "Yo-yo", Category = "Toys", Price = 3.75M }, 
            new Product { Id = 3, Name = "Hammer", Category = "Hardware", Price = 16.99M } 
        };

        public IEnumerable<Product> GetAllProducts()
        {
            return products;
        }

        public IHttpActionResult GetProduct(int id)
        {
            var product = products.FirstOrDefault((p) => p.Id == id);
            if (product == null)
            {
                return NotFound();
            }
            return Ok(product);
        }
    }
}

I just want the method to access the data.

Can anyone help me with this. Thanks

Answer 1

Use $http in your service or controller of AngularJS to access data from your Web API. For example:

$http.get("http://localhost:8080/api/products/getallproducts")
    .then(function(response) {
        console.log(response.data);
    });

Answer 2

If writing WebApi application then you need to change the IHttpActionResult Name to Get. and try this URL:

localhost:8080/api/products/{id}

*{id} is optional.

if you want to use the route you should change WebApiConfig.cs in App_Start folder.

Take a look at angularjs $http service which is used to establish communication with the http server in situation as yours.

To call GetAllProducts() , using the $http , use the route "api/products" like this

$http.get("api/products")
    .then(function(response) {
        console.log(response);
});

And to call GetProduct() use the route "api/products/1" if your product is 1 like this

$http.get("api/products/1")
    .then(function(response) {
        console.log(response);
});
