ASP. NET5 Web API Controller Class learning

ASP. NET5 Web API Controller Class learning

The Web API Controller Class is a template type used to add new items to ASP. NETWeb Application projects in VS2015. This template type generates a REST-style interface Class,

Why not choose MVCController Class?

Because we don't want it to involve a View, we don't need a View at all;

For masters, they are all the same, and the inherited classes are all the same, but the specific implementation is different;

For example, if other people already provide complete similar code, it doesn't matter which template to choose.

The sample code is as follows:

 

using System;using System.Collections.Generic;using System.Linq;using System.Threading.Tasks;using Microsoft.AspNet.Mvc;// For more information on enabling Web API for empty projects, visit http://go.microsoft.com/fwlink/?LinkID=397860namespace dotnethelloworld.Controllers{    [Route("api/[controller]")]    public class ValuesController : Controller    {        // GET: api/values        [HttpGet]        public IEnumerable
 
   Get()        {            return new string[] { "value1", "value2" };        }        // GET api/values/5        [HttpGet("{id}")]        public string Get(int id)        {            return "value";        }        // POST api/values        [HttpPost]        public void Post([FromBody]string value)        {        }        // PUT api/values/5        [HttpPut("{id}")]        public void Put(int id, [FromBody]string value)        {        }        // DELETE api/values/5        [HttpDelete("{id}")]        public void Delete(int id)        {        }    }}
 

 

Add method:

Right-click the project name and choose add> new project.

Select "server" on the left and "Web API Controller Class" in the middle. Enter the name you want to use in the Name field.

Browsing and calling:

When the VS2015 window is active, press F5 to enter the debugging status. A default browser window is opened, with the address similar to http: // localhost: 3753.

Note: The following ports are random;

For restful APIs, you can access only GET-type API requests in the address bar of your browser,

Let's take a look at the note of the Get () method: // GET: api/values

This shows that you can access this method through api/values. The access address is http: // localhost: 3753/api/values.

Let's take a look at the note of the Get (int id) method: // GET: api/values/5

This shows that you can access this method through api/values/5. The access address is http: // localhost: 3753/api/values/5.

The next 5 is the value passed to the corresponding int id. The type needs to be matched. If it does not match, the default value is 0;
