Self-host Web API Learning Notes

The ASP. NET Web API does not require IIS and can be implemented directly using a console program.

First, create a new console program, the project is named Hostapi

Ii. Setting the target framework for the. NET Framework 4

Third, NuGet Add Reference Microsoft.AspNet.WebApi.SelfHost

Iv. Adding a Product model class

usingSystem;usingSystem.Collections.Generic;usingSystem.Linq;usingSystem.Text;namespacehostapi{ Public classProduct { Public intId {Get;Set; }  Public stringName {Get;Set; }  Public stringCategory {Get;Set; }  Public decimalPrice {Get;Set; } }}

Five, add a ProductsController public class named. derive this class from System.Web.Http.ApiController .

usingSystem;usingSystem.Collections.Generic;usingSystem.Linq;usingSystem.Net;usingSystem.Web.Http;namespacehostapi{ Public classProductscontroller:apicontroller {product[] products=Newproduct[] {NewProduct {Id =1, Name ="Tomato Soup", Category ="Groceries", Price =1 },              NewProduct {Id =2, Name ="Yo-Yo", Category ="Toys", Price =3.75M },              NewProduct {Id =3, Name ="Hammer", Category ="Hardware", Price =16.99M }          };  PublicIenumerable<product>getallproducts () {returnProducts ; }         PublicProduct Getproductbyid (intID) {varProduct = products. FirstOrDefault (p) = P.id = =ID); if(Product = =NULL)            {                Throw Newhttpresponseexception (Httpstatuscode.notfound); }            returnproduct; }         PublicIenumerable<product> getProductsByCategory (stringcategory) {            returnProducts. Where (p =string.        Equals (P.category, Category, stringcomparison.ordinalignorecase)); }    }}

Vi. managed Web API

Open the Program.cs file and add the following usage statement:

using System.Web.Http; using System.Web.Http.SelfHost;    

Seven, modify the Main method

usingSystem;usingSystem.Collections.Generic;usingSystem.Linq;usingSystem.Text;usingSystem.Web.Http;usingSystem.Web.Http.SelfHost; namespacehostapi{classProgram {Static voidMain (string[] args) {            varConfig =NewHttpselfhostconfiguration ("http://localhost:1234"); Config. Routes.maphttproute ("API Default","Api/{controller}/{id}",                New{id =routeparameter.optional}); using(Httpselfhostserver server =Newhttpselfhostserver (config)) {Server. OpenAsync ().                Wait (); Console.WriteLine ("Press Enter to quit.");            Console.ReadLine (); }        }    }}

Run directly F5 and then open the browser to access:

Get all data http://localhost:1234/api/products

Get data in the code of 1 HTTP://LOCALHOST:1234/API/PRODUCTS/1

Querying the category= data http://localhost:1234/api/products?category=Groceries

Return:
