C#的web项目ASP.NET

添加实体类和控制器类

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace WebApplication1.Models
{
    public class Company
    {
        public string companyCode { get; set; }
        public string companyName { get; set; }
        public string companyStatus { get; set; }
        public string jobGrade { get; set; }
        public string parentCompanyCode { get; set; }
        public int sort { get; set; }
    }
}

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Web.Http;
using System.Web.Services.Description;
using WebApplication1.Models;

namespace WebApplication1.Controllers
{
    public class CompanyController : ApiController
    {
        Company[] companys = new Company[]
        {
            new Company { companyCode = "10", companyName = "XXX智能有限公司", companyStatus = "1", jobGrade = "测试",parentCompanyCode=null,sort=0 },
            new Company { companyCode = "20", companyName = "YYY科技有限公司", companyStatus = "1", jobGrade = "测试",parentCompanyCode=null,sort=1 }
        };
        public IEnumerable<Company> GetAllCompanys()
        {
            return companys;
        }
        public IHttpActionResult GetCompany(string id)
        {
            var company = companys.FirstOrDefault((p) => p.companyCode == id);
            if (company == null)
            {
                return NotFound();
            }
            return Ok(company);
        }
    }
}

那么，问题来了。访问路径我是从何得知的呢？其实是从WebApiConfig.cs文件中找到的。

WebApiConfig.cs

namespace WebApplication1
{
    public static class WebApiConfig
    {
        public static void Register(HttpConfiguration config)
        {
            // Web API 配置和服务

            // Web API 路由
            config.MapHttpAttributeRoutes();

            config.Routes.MapHttpRoute(
                name: "DefaultApi",
                routeTemplate: "api/{controller}/{action}/{id}",
                defaults: new { id = RouteParameter.Optional }
            );

            //去掉xml返回格式、设置json字段命名采用
            var appXmlType =
                config.Formatters.XmlFormatter.SupportedMediaTypes.FirstOrDefault(t => t.MediaType == "application/xml");
            config.Formatters.XmlFormatter.SupportedMediaTypes.Remove(appXmlType);
        }
    }
}

其中，/{controller}/{action}/{id}的controller是CompanyController中的Company，action是方法名称GetAllCompanys，id是GetCompany方法的参数。
